Some Common Overhead Crane Hazards Tips to Help Avoid Them

Some Common Overhead Crane Hazards and Tips On How to Prevent Them

Preventing Overhead Crane Hazards: In any type of industry, the coming together of anticipation and pro-actively handling problems is something, which does result in greater success than just reactively responding to incidents. If an individual works in the world of construction and manufacturing, there are hazards always present at job sites, but with proper training and preparation ahead for them, a lot of issues can be prevented.

In order to keep all those involved safe, all operators and workers need to understand the most basic of all safety hazards, and how to recognize any of them right away. Please read on to learn more about the many potential risks that are a part of overhead cranes and the accompanying preventable measures.

Potential Electrical Hazards

About 50% of all crane accidents that happen overhead can be attributed to machinery coming into contact with a power source of some kind during operation. Typically, why this occurs is because, as a crane moves materials close to or beneath energized power lines, the hoist line or boom gets into contact with the electrical source. This is an issue, which is about half of all hazards that are associated with these overhead cranes, and it can be stopped with good safety planning.

Safety planning that is effective can be done before the cranes even get to the worksite. It is important to establish who will be in charge of any and all pre-job safety. Every danger zone should be clearly marked, and this does specifically apply to, the 10-foot radius of all power lines of the entire area. The whole area should be considered to be an unsafe working place from the get go. The 10-foot radius can be marked with barriers, fences, taping, etc. to give clear visual clues for all workers.

In addition to this, make sure to ask electrical companies to de-energize or to ground any existing power lines when there are individuals working in close proximity to them. However, until specifically informed by the electrical company, all operators should assume that all power lines are energized and extremely dangerous. A final preventative measure is to make sure all ladders, tools, and other systems being used on the work site aren’t at all conductive.

Crane Overloading

When a crane exceeds over its operational capacity, it can also prove to be the very thing, which tends to cause about 80% of all crane accidents and structural failures as well. The overloading of the crane’s operational capacity is caused by some of the following:

  • The presence of swinging or a sudden dropping of any load
  • Any defective components
  • The hoisting of a load that is beyond its normal capacity
  • The dragging of a load
  • Whenever side-loading a boom

A lot of these mistakes are the result of predictable human error. The formal training for operators should have a working knowledge of some key points, and any conditions where stated lifting capacities happen to be valid. Some of these key points are crane load charts and lifting capacities. Operators shouldn’t just rely on instinct or experience to decide if weight load is correct.

Any Materials Falling

One of the best ways to lessen the chance of any materials falling down from cranes is clear. It is to make sure to perform regular maintenance of hoists. An example of this is to do load testing maintenance to ensure that you know how many pounds a hoist can handle exactly. It also will provide an accurate indication of just how well the hoist is functioning currently. Another way to reduce the chance of mechanical failure is by performing inspections of the crane each day. If, and when, a potential problem is identified by the operators, they need to make sure to implement the lockout/tag-out procedure.

Though it may be obvious, what should be clearly stated is this, that workers need to always wear the proper head, foot, hand, and eye protection while working on the job site itself. They also need to be constantly aware of what is going on in their surroundings. They don’t want to accidentally go walking beneath a suspended load at any time.

Here at TNT Crane Service, Inc., we always make sure to put safety and prevention first. It is our number one priority. Because of this fact, we ensure that all the machines we have are kept well maintained and up to date. What this does is ensures that you will be getting the most effective, as well as, the most reliable equipment that is available. Please view the equipment that we have on hand for sale or rental today. It may help you to find the crane that you require for your next major project coming up.

New Wire Rope Standard in the Works

New Wire Rope Standard in the Works

A proposed engineering standard for wire rope for cranes will have separate chapters for steel and synthetic ropes, a member of the committee working on the standard told a crane and rigging conference in Edmonton last fall.

At the time, Bill Fronzaglia expected the new standard, called ASME B30.30, would be approved by a ballot at a subcommittee meeting in January. However, according to a June 2016 public schedule from the American Society of Mechanical Engineers, which develops the ASME standards, the B30.30 wire rope standard was still under development. And an agenda item from an ASME B30 standards committee meeting held in Houston in May 2016 noted that the ballot on the rope standards draft had been withdrawn. That was because of “the extent of the changes to the document” in evaluating comments.

The subcommittee planned a final review of a revised document after the May main committee meeting and anticipated “resubmitting a new first ballot shortly afterward.”

Deborah Wetzel, the society’s manager of media relations, confirmed by email in July that the B30.30 standard was still under development and had not just been approved by the B30 standards committee. Once that approval takes place, the public will have a chance to review the standard and submit comments during a public review process that will be announced on the ASME website at https://cstools.asme.org.

“Since our standards are developed under a consensus process, we are unable to predict when the committee will reach consensus on this new volume,” Wetzel said, adding that “a timeline for approval/publication is not available at this time.”

Of the 29 existing ASME B30 standards, “16 are incorporated into Canadian provincial and territorial regulations,” according to an August 2014 report of the Standards Council of Canada on hoisting and rigging regulations in Canada. However, none of the ASME B30 standards are incorporated into any federal Canadian regulations. As of August 2014, B.C. had incorporated 13 ASME B30 standards, the most of any Canadian jurisdiction. Yukon had incorporated 12, Nova Scotia, 10 Manitoba 6, and Newfoundland two. None of the other provinces or territories had incorporated any.

In Europe, the situation with synthetic rope is more complicated than in the U.S., Fronzaglia said. The European Union has a machinery directive that for a piece of equipment that doesn’t have a standard, a manufacturer can create a technical file and show evidence that it works and is safe, Fronzaglia said. That enables the manufacturer to place a CE mark on the product, such as on a high-performance sling.

However, the European Federation of Material Handling has met with major crane manufacturers to develop a standard “in a short period of time” that won’t be legally binding but will act as a guideline.

And the International Standards Organization in a meeting of Technical Committee 96’s subcommittee SC 3 redefined wire rope for cranes as applying to ropes “regardless of their material properties,” Fronzaglia said.

Basically that means the committee acknowledged the need to develop a synthetic crane rope standard, he added.

For all of us at TNT Crane, we realize that this is an integral part of crane safety.

Use Cranes In A Safe Manner

Use Cranes In A Safe Manner

How to perform the safe operation of cranes? Cranes have made a lot of things easier. In order to operate cranessuccessfully and efficiently, the safety considerations need to be taken into account. The safety of the persons operating the crane as well as the all others around it is of prime importance. Following are some tips which can be followed to ensure the safe operation of cranes:

License:

Obtaining the license of crane operation is the first thing that all the crane operators must do. The National Commission for the Certification of Crane Operators (NCCCO) handles the standards for crane operator certificates. Crane operators must prove their knowledge of efficient crane operation by obtaining the certification.

Mobile Crane Computer:

You should never override the computer of the mobile crane.

Be Mindful of Your Surroundings:

Be aware and alert about your surroundings. Be watchful and observe all overhead hazards, including power lines and nearby buildings.

Create a checklist before operation:

Prepare an operating manual which includes all the steps and safety procedures of the crane operation, along with a checklist. The checklist should include:

  • Checking hoist
  • Examination of loading chain
  • The place and positions of hooks

Ground Conditions:

Ensure that your mobile crane can easily be supported and safely operated on the site.

Pads and Cribbing:

Ensure that appropriate pads or cribbing are being used.

Don’t Ignore The Safe Working Load (SWL):

One can easily make a mistake of thinking to lift more than the SWL of the crane, which can be a really hazardous task. The definition of SWL is self-explanatory – the crane cannot lift more than that safely. Make sure that all the operators are using the right sized crane, sling and equipment for the current job.

No Slack Chains:

It does not matter if your workers are fresh or highly experienced, they should not operate the crane just based on their instincts as it can be very risky. The chain or wire must be taut and firm before lifting any load. The operators must ensure:

  • Never run the hook with a slack chain
  • The chain or wire must never be bent on sharp edges
  • If they see any damaged chain or wire, they must immediately report it

Oil and Fluid Levels:

Before staring the crane, ensure that there is sufficient gas, oil and any other type of required fluid.

Other Safety Precautions:

Indeed, even with all of the safety precautions, there is still a chance that accidents may happen and it is essential that you know what steps to take in case of an accident. Take all the necessary precautions like ensuring that the proper attire and safety equipment are worn by the operators.

Ensure that all the personnel are properly trained to handle an emergency situation so that the risks and problems may be minimized in case of an incident.

Conclusion:

Operating cranes with proper safety precautions can make the workplace safer and the work more efficient. Make sure that all the operators are licensed to operate the cranes in order to have a great working place with a safe atmosphere.

Overhead Crane Inspection Guide

Overhead Crane Inspection Guide

Being prepared is the best way to avoid an accident, and this is especially true when it comes to overhead cranes. OSHA has found that an average of 71 crane-related fatalities happen each year. In most of these cases, an inspection could have identified the fatal problem before tragedy struck. That’s also not counting the thousands of less-serious accidents involving cranes that could have been prevented if the equipment had been subjected to the required inspection. Although these accidents may not result in the loss of life, they can result in injuries as well as serious fines for safety violations and costly downtime.

Regularly inspecting overhead crane equipment is one of the most important steps companies can take to cut down on these unfortunate crane-related incidents. However, it is crucial that operators and supervisors do more than give their equipment a quick glance to see if everything simply looks all right. Overhead crane equipment must be put through a rigorous and thorough inspection process before it can be cleared for safe crane operation. What’s more, there are dozens of inspection points that must be checked during these inspections. Additionally, certain inspection points must be checked on a more frequent basis than others, so it is essential that operators and supervisors understand OSHA’s requirements for these inspections. The following crane guide illustrates many of the most important inspection points on overhead crane equipment. By following it, companies can help ensure that their equipment and their job sites will be much safer and better prepared.

How To Find The Right Crane

This article will teach you how to find the right crane

Almost all the industries rely heavily on cranes. They can lift and move extremely heavy objects with unreal ease. The importance of cranes cannot be denied in any way. They are extremely reliable and the success of mega projects depends heavily on cranes.

If you have the need for a crane, you need to understand the importance of selecting the right crane for yourself. To be able to do that, you need to understand the details and specific things regarding the project.

Crane Cafe is passionate about cranes and we are excited to share all the cool stuff related to cranes. An article is shared here, which is in the form of questions and answers and  will teach you how to find and pick the right crane for yourself.

Read the full article to learn more!

Following are the questions and answers that you need to know in order to select a proper crane for your project:

What Load is Being Lifted?

Loads can shift at random intervals, and they may be balanced in unusual ways. One important part of deciding which kind of crane to use is to determine what type of load you are going to move. This inquiry process needs to include both the materials inside, and the method of containing them. A liquid inside a tank is going to have dramatically different movement characteristics than a flat car trailer full of tightly packed solid objects. Exploring the entire fleet of possibilities can benefit you if you are unaware of the types of cranes available to you.

How High is the Work to Be Done?

The height of the work is going to impact how the boom is set up, as well as what kind of boom will be necessary. Furthermore, the extension of the crane’s boom can be affected by the wind, which increases exponentially as the height increases. In addition, the amount of counterweight needed to heft loads to ever-increasing heights needs to be calculated differently versus if the height is lower. Tower cranes now have dramatically higher capacity than they once did, and they can often lift over 1,000 meters into the air.

What Kinds of Obstacles are There?

In many environments, especially urban and suburban ones, cranes need to be adapted to circumventing obstacles. In addition to winds, there may be power lines, other buildings and other obstacles that can keep a crane from being able to simply raise the load directly from its origin point to its destination. In some instances, even the control scheme the crane uses can be difficult in the presence of obstacles, with pendant station cables getting caught. Radio controls may be more effective and less potentially hazardous.

How May the Crane Affect the General Public?

Just like how tower cranes are affected heavily by windy weather, the public in the area the crane is operating may be affected by this operation. If the crane’s size impacts the flow of traffic beyond a reasonable threshold, this can cause problems for the entire construction site. Further, if the crane is likely to cause issues with the operation of nearby buildings, this needs to be taken into consideration prior to selecting the type of crane you are going to use for your project.

Lumens, not watts

Forget what you know about incandescent lamps — your watts are no good here.

When shopping for bulbs, you’re probably accustomed to looking for watts, an indication of how bright the bulb will be. The brightness of LEDs, however, is determined a little differently.

Contrary to common belief, wattage isn’t an indication of brightness, but a measurement of how much energy the bulb draws. For incandescent lamps, there is an accepted correlation between the watts drawn and the brightness, but for LEDs, watts aren’t a great predictor of how bright the bulb will be. (The point, after all, is that they draw less energy.)

You’ll pay more for an LED light bar

LED light bars are like hybrid cars: cheaper to operate but pricey upfront.

When switching to LED light bars, don’t expect to save buckets of cash. Instead, think of it as an investment. Luckily, competition has increased and LED light bars have come down in price but you should still expect to pay much more than an incandescent light.

Eventually, the LED light bars will pay off, and in the meantime, you’ll enjoy less heat production and longer lifespan.

The complete article describing the various things that you need to learn before getting LED light bars will explain everything in detail.

A Good Guide For Crane Operator Hand Signals

Crane operator hand signal guide

A Guide explaining different hand signals for crane operators

Cranes are extremely important for all industries. Be it construction, production,  car manufacturing or cargo industry, cranes are an essential and inalienable part of the industry.

Operators need to be attentive, vigilant and cautious while operating the cranes. Although, accidents can not be completely avoided but they can be mitigated and the best way to do it is by being careful.

Safety should be the primary concern in all the industries and there should be no compromise on incorporating the safe practices. Crane Cafe is aimed at presenting you the best quality content. With that spirit,  presented here is an article which highlights the importance of hand signals in operating the crane safely. The article also explains various hand signals and their meanings.

Read the complete article to get this valuable information!

The definitions and explanation regarding different hand signals for crane operators are as follows:

Hoist

To hoist, or raise the load, the signaler stands with his/her right arm bent 90 degrees upward. From there, the signaler points his/her finger upward and and turns it around from the elbow in a counter-clockwise motion.

Lower

Lowering the load is where the signaler places his/her right arm pointing straight downward to the side by the hip, points the finger off to the right, and turns the finger around from the elbow in a counter-clockwise fashion.

Raise Boom

To raise the boom, the signaler begins with the right arm outstretched to the side. From there, the signaler points the thumb upward.

Lower Boom

To lower the boom is the reversal of the signal to raise the boom. The signaler begins with the right arm outstretched to the side. From there, they point their thumb downwards.

Dog Everything

Dog everything, or pause, can be useful if the situation changes, if there is a need for further instructions, or if there is the potential for danger. The signal for dog everything is to place the signaler’s hands clasped in front of the stomach.

Stop

To signal stop, the signaler bends his/her elbow with the upper arm extended, palm down, and rhythmically extends and retracts their hand to a fully extended arm out to the side. Emergency stop is the same, only with both arms.

The information relating to other hand signals for crane operators can be obtained by accessing the brilliantly written article on TNT Crane & Rigging. Read the complete article to obtain the information and spread to your crane operators and workers.

All of us at Crane Cafe send our deepest condolences to the families of the men who died and a speedy recovery to the person who was injured.

How Working at Night Can Create a Safer Jobsite

Today, highway construction in urban areas is almost always performed at night. State Departments of Transportation (DOTs) around the country have discovered that night jobsites are safer and more efficient for a number of reasons.

  • Roadways can be closed at night without major public inconvenience.
  • Traffic is not an issue.
  • Worksites can be expanded.
  • Cranes have more space in which to operate and swing.

Working at night

OSHA and DOTs have developed comprehensive safety measures for nighttime jobsites, and modern construction lighting systems create a work environment that is as luminous as working in daylight. Crane-owning companies are adjusting to the increase in nighttime work, and crane manufacturers are looking for ways to adapt cranes to these conditions.

At ConExpo in March 2014, Link-Belt introduced its first crane with a standard lighting package, the 210-ton capacity ATC-3210. The lighting package on the new all-terrain crane makes it easier to set up and rig the crane in the dark hours of the early morning or dusk. There are high intensity LED lights on the front of the operator’s cab and at the outriggers. The engine bay now has lighting as do the ground control stations for outriggers and suspension. Other optional lighting includes high intensity work lights above the operator’s cab, lights that illuminate the walkways on the upper, a right-side, forward-facing high intensity work light and left and right high-intensity work lights mounted atop the upper to illuminate the swing area. Plus, remote-controlled single and dual boom floodlight options are available.

Albuquerque, NM-based Crane Service Inc. recently took delivery of a new Link-Belt ATC-3210 and has already seen the value in the new lighting package, according to Bob Warianka, business development manager.

While his company doesn’t do that much night work, he said it is becoming more prevalent. Warianka pointed to a recent job that involved the company’s ATC-3210 and ATC-3275 setting bridge girders at night.

“The contractor had the job lit up really well, with four light plants illuminating the work area of each crane,” he said.

While the crane’s lighting package isn’t really a factor in lighting up the worksite, it’s still a great convenience for rigging the crane.

Rigging asset

“The lights are really an asset when you are rigging the crane or setting it up in the early morning hours, or sometimes we will assemble a crane at night,” Warianka said. “We envision more crane companies offering better lighting packages in the future. I can see them being used on rough terrain cranes too.”

He said crawlers cranes would be the least likely cranes to be equipped with comprehensive lighting packages because the type of work they do at night generally involves a well-lit jobsite, and rigging a crawler is different than rigging a mobile crane.

“Tower cranes have lights on them,” said Warianka. “Tower cranes are sometimes on a job working 24 hours a day and two shifts. With mobile cranes, we can see a need for a lighting package for the short days of winter or when you want to keep working at dusk or during cloudy weather. These lights will also come in handy when doing concrete pours, like on a high-rise job. Sometimes concrete pours go into the night or start early in the morning. The lights you use on a crane will be job specific.”

Remote controls

In a few cases, Crane Service has provided lighting equipment, for instance when the crane might be grabbing on and needs to be tied to the load for a while.

He has been impressed with the remote-controlled lights on the new ATC-3210.

“The light on the boom can be operated by remote control so that you can actually rotate the light and spotlight something below the crane,” he said.

Rick Curnutte, product manager, telescopic truck and all-terrain cranes, Link-Belt, said the driving factor for the lighting package was lighting the jobsite, but for set up and tear down of the crane.

“People in our industry tell us what they want to see on a crane and we try to listen,” said Curnutte. “In order to beat traffic, cranes are being dispatched much earlier to the jobsite, and to be there in a timely manner, crews are often setting up the crane in the dark.”

Rigging a crane at night without big jobsite lighting systems means the crane owner will have to bring out his own lighting system. With a crane lighting package, the rigging is much easier.

Curnutte said that not having a lighting package makes it difficult to lay down mats and perform the ordinary challenges of rigging the crane in darkness.

Customer feedback has been positive, especially the remote control boom lights and the engine bay lights that allow the operator and rigger to check the oil and provide maintenance to the crane.

“There are lighting packages for looking down at loads on the boom and cab lighting, but I don’t think anyone has gone to the extent that Link-Belt has gone to,” Curnutte said.

While the new lighting package from Link-Belt has only been out for a few months, crane lighting has become a topic of discussion for customers, he said.

“It’s still early and there’s been a lot of discussion. How far we take it down the product line is going to depend on the demand we see. Definitely for the ATs it’s been a hit and the ATC-3275 will get the same lighting package as the ATC-3210. This idea definitely struck a chord when we showed it at ConExpo.”

Again, Curnutte stressed that Link-Belt’s goal with its crane lighting package is not to provide lighting for the jobsite lifting.

“There are some aspects of lighting we did that do benefit the jobsite, but you have to be cautious about using some of those lights during lifting because you have ground personnel who need to be able to look at the operator in the cab, and you don’t want the light affecting their vision or ability to see what they need to see. But generally, we feel like we’ve hit a home run with this lighting package.”

Recent Use of Zoomlion Tower Cranes to Erect the Astana Expo 2017

With the recent Expo 2017 coming to Astana, Zoomlion placed and used multiple tower cranes to erect the pavilions main buildings.

The building has a diameter of 80m and a height of 100m, with pavilions of other countries evenly distributed around it in a ring shape.

Twelve large-tonnage Zoomlion tower cranes, seven Zoomlion truck cranes and one Zoomlion bulldozer have participated in the pavilion construction.  “Among which four Zoomlion D1100-63, the super-large tower cranes with the maximum hoisting capacity in the Central Asia,” said the manufacturer.

The D1100-63 is a new model of self-climbing tower crane, featuring superstructure slewing, double lifting points, level jib and horizontal trolleying. With a hoisting capacity of 9.8t at the 80m jib end, the tower crane adopts variable frequency stepless speed-regulating motor to significantly optimize the system’s running stability and improve positioning accuracy.  PLC (programmable logical controller) is used to control all actions.

The event will take place between June 10 and September 10, 2017.

This was the second time that Zoomlion has been involved in Expo construction, having helped to build the Chinese Pavilion in Expo 2015 Milano.

Zoomlion said: “The direct economic and trade cooperation and cultural exchanges between China and Kazakhstan are of far-reaching significance to promote the development of the “Belt and Road” [Chinese government-backed investment and trade strategy]. As a leading enterprise in the engineering machinery industry, Zoomlion has explored the market in Kazakhstan for over ten years, dedicated to efficiently helping the construction of local infrastructures.”
