Hoisting and Rigging Hazards
The hoisting and rigging activities must be performed by trained personnel. Many rigging accidents occur due to the lack of knowledge of the rigger. The rigger must know the following facts to operate a sage rigging operation.
- Weight of the load and the rigging hardware
- Working load limit of the hoisting rope, hardware, and slings
- The capacity of the hosting device
After these points, the rigger must know how to lift the load stably. When a crane rental operator works with a rigger in any operation, the operator must be evident in communication and signals used during the process.
Factors affecting the Hoisting Safety
The following factors are factors affecting hoisting safety and must be observed keenly during the operation.
Workload limit: never exceed the workload limits and do not work on any assumptions. You must be precise about the weights you are working on and reference source documentation related to the lift load.
Unknown equipment: if you are not sure of or aware of any equipment or part of the system, do not use it and get the correct information on its proper use from a competent source.
Defective components: To avoid damaging or destroying loads or parts, first start by conducting a thorough examination. of the hoisting system.
Extreme winds: Please beware of the hazardous windy weather as it may cause disturbances in balancing and cause the load to swing or twist.
Weather condition: some typical climate factors such as fog, snow, darkness, rain, or dust may cause reduced visibility and do not perform any operations in such weather.
Electrical contact: you should not perform hoisting operations near powerlines to prevent any electrical hazards which may result in the deaths of riggers. It is good to maintain approximately 10 feet minimum distance from a powerline of any kind at all times.
Crane Sling Rigging
A sling is an essential part of the rigging equipment. Take care of the following precaution while using the sling.
- Check carefully that the sling is not damaged, cracked, rusted, or corroded.
- Mark every sling with the weight capacity it can hold.
- Avoid crushing, pinching, and sharp bends.
- Do not let slings lie on the ground or moist surfaces for an extended period.
- Do not drag slings from beneath the loads.
- Never wrap a wire sling around a hook.
- Never tie the knot in slings.
- Balance the load on multileg slings.
Rigging While Lifting and Landing Loads
Follow the mentioned guidelines while lifting and landing loads.
- Ensure to rig the load entirely before it is set in motion to prevent it from dislodging or shifting.
- Manage to control the load at every moment during its shift.
- Land the loads safely and block the load before unhooking it. Blocking prevents the slings from being damaged.
- Do not wrap the load with the hoist rope. Attach the load to slings, hooks, or some rigging device.
- Use gloves while you are handling wire ropes.
- Make should make the area of operation clear of obstacles while lifting, moving, and landing the load. The slings might get loose at any moment.
- Do not make temporary repairs to the slings. If it is possible, get it appropriately repaired or discard it.
- Secure the extra legs of the sling before the operation.
- Lift the load slowly and make sure that the slings have taken the load.
- Avoid sudden movement during the operation to include construction crane operations
Fiber Ropes Used in Crane Operations
Fiber ropes are most commonly used in the applications of hoisting. Both natural and synthetic fiber ropes are available for the purposes. If you are using natural fiber ropes, take extra care as they are quickly deteriorated by mildew, rot, and chemicals compared to the synthetic ropes.
Among synthetic ropes, polypropylene, nylon, and polyester ropes are available. When they are wet, they can conduct electricity.
Inspect the ropes before every use and look out for cuts and wears in the ropes. Discoloration and variation in the shape and size of strands are a sign of its deterioration. Broken and excessively loose yarns also ask for a change in the rope.
Keep the ropes in a cool, dry place with good air circulation. Hang them on large pegs on the wall, and don’t leave them on the ground. Keep the ropes away from heat sources, radiators, steam pipes, chemical fumes, and gases. Suppose the rope gets wet during use dry or before storing them. Do not overload a rope and avoid dragging on sharp or rough surfaces as it will cause wear and tear.
