Description

Product Description



We have all heard the phrase... "A chain is only as strong as its weakest link". When it comes to crane operations, rigging can often be that "weak link". How a load is attached to a crane can make the difference between a successful lift and an unfortunate accident. And rigging-related accidents can often be deadly, due to the large and heavy loads that are lifted. Once a load or a crane itself falls not much can be done to stop it, and there is little time for people to move safely out of the way. OSHA has become so concerned about crane and rigging accidents that they have recently revised their crane safety regulations… for the first time in almost 40 years! 

Atlantic Training's "Rigging Safety" VHS or DVD training program point out to employees that over 90% of rigging-related accidents are caused by human error... and that they are the key to preventing these incidents. Topics covered in these products include:

Rigging Safety

From freight, to equipment, to building supplies, loads come in all shape and sizes, and there are many different ways that can be reached so that the crane can lift them. If we miss a step in the rigging process, things could go seriously wrong. As we all know, anytime we're dealing with cranes, it can be dangerous.

OSHA Regulations

Because of the hazards associated with working with cranes, OSHA has had crane safety regulations enforced for sometime. But until recently, they haven't been changed for almost 40 years. However, with the crane related accidents in the construction industry increasing rapidly, in August of 2010 OSHA updated a number of provisions in the construction portions of the regulations. To be more in tune with today’s sophisticated equipment and operating environments. 

The crane regulations cover a number of areas, including:

  • Ground conditions.
  • Assembly and disassembly.
  • Work around power lines
  • And inspections.

They also address:

  • Signaling.
  • Fall protection.
  • Work area control.
  • Operator certification.
  • Qualifications for "signal persons" and maintenance personnel.
  • And training.

While you should be familiar with all of the provisions of the crane regulations that affect you and the people that you work with, some of the recent changes in the regulations are particularly notable. Before a crane is positioned or assembled, it must be verified that the "ground conditions" are firm, drained and graded so that the crane can set up safely. Crane assembly, disassembly and set-up must be overseen by personnel who are "competent" and "qualified". There are new restrictions as to how far a crane must be from power lines when it is being assembled, operating or traveling. Generally it must be at least 20 feet away at all times. But this can vary depending on the amount of current going through the lines).

By November 10, 2014 all crane operators must be "certified" by either: 

  • An accredited testing organization.
  • A licensed government agency or a qualified employer program.

"Signal persons" must be "qualified" by either:

  • A "third party qualified evaluator".
  • Or their employer’s own "qualified evaluator". They set the criteria OSHA specified in the regulation.

A maintenance employees can only operate a crane as they work on it if they’re familiar with how that specific type of crane functions or they’re directly supervised by a qualified or certified crane operator. The first step to preventing accident is preparation. Let's begin by taking a close look in a unique set of signals that are used in a rigging process.

Hand Signals

Communication is essential in a riggers work. In order to move a load successfully, both the rigger and the crane operator need to use a number of hand signals. Let's review the basics. 

To indicate to an operator that  you want to hook on a crane lowered, point downward and move your hand in small circles. When the load is ready to be hoisted, raise your arm and point up, then again move your hand in small circles. By extending one arm out to the side with your palm facing down and moving your arm back and forth horizontally, you can show that you want the crane to stop. To call for an emergency stop, extend both arms out to the sides with palms down and move your forearms horizontally.

There are two other special signals that are used only when working with boom cranes. To show that you want the boom to be lowered, extend your arm, close your fist and point your thumb down. When you need the boom raised, extend your arm, close your fist and point your thumb up.

Once you're comfortable that everyone can communicate effectively, check with the operator to make sure that the crane has been inspected. That way both you and the operator will know that the crane is ready to lift safely.  

Make sure that you both know the weight capacity of the crane. This will help you to not overload it. Inspecting the hook is important too. Never used a hook with a broken or bent safety latch on it. The sling could slide off with the hook and damage the load or cause an injury. Keep in mind that hooks are made to carry loads at their centers. Never lift a load on the tip of the hook. This can cause the hook to stretch and weaken. If the hook you're about to use has an opening that are stretched 15% or more from its original size or twisted more than  10 degrees, don't use it. Take the time to get another hook.

Once the crane and hook has been inspected, you could move on picking out the proper sling for your job.

Slings

Slings are used to carry a load, they can be made up of many different types of materials, such as:

  • Chain
  • Wire Rope
  • Synthetic Fabrics
  • Or Metal Mesh

When choosing a sling, consider the size, shape, and even the temperature of the load. Knowing the temperature of the load is important because some sling may stretch, melt or even break in extreme heat. By selecting the right sling you can make rigging and controlling the load a lot easier and safer. Let's take a look.

A chain sling should be used for lifting your heaviest loads. It also works well when you are in a high temperature environment such as a steel mill because it's less likely to be damaged by heat and other type of slings. Before using a chain sling inspect it for cuts or worn links by pushing the links together and checking where metal rubs metal, you can find hidden worn spots and catch other potential problems.

Synthetic slings are the most flexible type of sling and are used when loads have to be protected from abrasion. Their light weight also helps to reduce fatigue and needed stressed you may experience on the job. Metal mesh sling are best for lifting object with sharp edges such as plate steel, since the edges can cut through the mesh. Metal mesh sling also make it easier to balance a load because of their wide load-bearing surfaces.

The most widely used type of sling is the wire rope sling. These are commonly found at construction site and other rugged environments. Before working with a wire rope sling, inspect it for broken or worn wires. Check the end connections for corrosion, kinks, crushed or broken wires and unwinding strands. If you find any of these conditions don't use the sling, it could be a hazard to you and to the lift.

Once you have picked up your sling, you are ready to attached the load, you should start by determining which hitch to use. Let's check it out.

Hitches     

A hitch is the way a sling is attached to the load and a hook. There are three basic kinds of hitches:

  • Vertical Hitch
  • Basket Hitch
  • Choker Hitch

You can only use vertical hitches on loads equipped with lifting attachments such as eye bolts or latches. To create a vertical hitch, just attached the hoist hook to the sling then connect the sling to the lifting attachment.

A choker hitch works particularly well with wide loads. Wrap the sling snugly around the load then run one into the shackle on the other end and fasten it to the hook. Sometimes a regular choker hitch isn't tight enough. In this situations, you should use a double wrap choker hitch. Wrap the sling around the load twice then loop one into the other and attach it to the hook.

The most commonly used hitch is the basket hitch. To form this hitch, cradle the sling around the load then place both ends of the sling over the hoist hook. When deciding which hitch to use, keep in mind that the same factors that apply to slings also apply to hitches. Both the hitch and the sling are affected by weight, size and shape of the load. For example, because of its length a long metal pole will need a double wrap choker hitch to keep it in place and you will want to use a synthetic sling since its flexibility and strength will help keep the pole stable. 

No matter which hitch you're using, it's important not to wrap the hoist rope around the load. This could damage the rope, the hook or the load itself. The hoist rope should only be used to lift and lower the hook. After you have selected which sling and hitch to use, you still need to determine how to prevent the load from damaging the sling. The easiest way to do this is to place padding around the sling, to protect both the sling and the load, you could place wood or other softeners between them. This will help to prevent the sling from cutting into the load as well as stop the load from causing wear and tear on the sling. Sometimes a load needs more than one sling to keep it stable as it's being lifted. To figure out the safest way to rig the slings, we need to look at sling angles.

Sling Angles

A sling angle is the angle between the sling and the load itself. By paying close attention to sling angles for each sling we rigged, we can be sure that the load will be safe and secure while it's being lifted. The force exerted on each sling increases as its sling angle decreases. If this force exceeds the slings weight capacity, the sling could break. 

A sling angle of 90 degrees is ideal because it puts the less stress on the sling. There are two ways to get a sling angle of 90 degrees. One is to use a lifting attachment and the other is to use a single sling. Unfortunately, most loads don't have lifting attachments and many loads require two slings. To find the right sling angle for two or more slings, ask your supervisor for a sling angle chart. A sling angle chart list various sling angle factors, if you are using two slings to lift a load, multiply the sling angle factor by half of the weight of the load, that way you could determine what the weight capacity of each sling needs to be. 

For example, the sling angle factor for two slings attached to a load at angle 60 degrees = 1.155 so, for a 1000 lbs load you will multiply 500 lbs, half the load's weight by 1.155. This tells us that each sling would need to be weighted for at least 578 lbs.  If the sling angles were 45 degrees, the chart would tells us that each sling would need to have a weight capacity of at least 707 lbs. Sling angles of less than 45 degrees should be avoided because they put too much stress on the sling. Keep in mind that the shorter the sling the sharper the sling angle will be. So, if you use slings that are too short, you could easily overload them causing the slings to break. By taking your time by consulting the chart you can catch sling angle problems and find the slings that are right for your lift.

Now that you know how to rig a load, it's time to lift it. Cranes are only intended to lift straight up and down. A diagonal lift puts too much stress on the crane and could tip the crane over. So before you lift, make sure that the operator has position the crane directly over the load and that the out riggers are extended and planted firmly on the ground. 

While lifting, you also need to be careful on accidental drops. Most often accidental drops are caused by having a bad angle of the load, (the angle between the load and the level ground). Most drops occur when the load is not parallel to this ground level. Never let the angle of the load exceed 10 degrees. More than that and the load could slip and fall and material could be damaged or people injured. 

While accidental drops are dangerous, the most common hazard that a rigger faces is electrocution and the most frequent cause of electrocution is contact with overhead power lines or electrical equipment. Make sure that you know the height of any power lines near your job site as well as the location of all electrical equipment before you start work. This way you can direct the crane away from danger. You should also keep an eye on the weather, you don't want to stand next to a crane or hold onto a tagline in a storm. If you do, you could easily become a target for lightning.

Now that we've rigged the load safely and know what hazards to look out for during a lift, we're ready to move on.

Making the Lift

As the lift progresses you need to pay close attention to the load. Often it can shift and change the angle of the load. Remember, the angle should never exceed 10 degrees from horizontal. Once the load is in the air, the next step is to move it. To help control and position the load, it is often a good idea to use ropes or taglines. By putting tension on the tagline, you can prevent the load from spinning, or help direct it toward its destination. Taglines can also help you maneuver the load into tight places. During the lift, stop periodically to make sure that the load is secure. As you travel with the load, do not carry it above people or allow anyone to walk under it. When you come to a stopping point, remember, a suspended load should never be left unattended. It is an "accident waiting to happen", so move to within a few inches of a good landing point then slowly lower the load until it is "grounded".

If the load is at its final destination, make sure you remove the slings from the hook. If they are left on the hook, they can snag on other objects when the crane starts to move again. Make sure you return the slings to their proper storage place.

Now that we know how to rig, lift and land a load, lets look at one last set of precautions you should take whenever you are rigging. Wearing the necessary protective clothing for the job. The right clothes and gear can protect you from cuts, bruises and other more serious injuries as well. First, its important to wear heavy leather gloves. They protect your hands from rope abrasions and sharp objects. Safety shoes and steel toes should be worn to protect feet from dropped loads and heavy equipment. A hard hat and safety glasses will help protect your head and eyes from falling or hanging objects. Sleeveless shirts can leave arms exposed to sharp objects and rough surfaces so make sure you that you are wearing a shirt with sleeves that can protect you from cuts and abrasions and don't forget to tuck your shirt tails in, so they will not get caught on the sling or the load.

Rigging plays a pivotal role in crane operations. If a load is not rigged properly, the consequences can be devastating. But by taking the proper precautions, you can get the job done safely.

Let's review:

  • Know the OSHA crane regulations and how they affect you and your co-workers.
  • Before rigging a load, make sure that both you and the crane operator know the standard hand signals.
  • Know the weight capacity of the crane and the lifting accessories that you're using.
  • Familiarize yourself with the different types of slings and hitches that can be used to rig a load.
  • Make sure every load you rig is secure and at the sling angles are safe.
  • Never carry a load above other workers or allow anyone to walk under a load.
  • And be sure to wear the proper protective clothing and equipment for the job you're working on.

See? It's not so hard after all, once you get the hang of it, it can be easy to rig and move a load safely.
