How Riggers Help With Ensuring a Safe Crane and Rigging Operation
When it comes to lifting and lowering heavy loads by crane, crane operators require the input of riggers. Crane riggers perform different tasks to ensure a safe rigging operation.
Read on to learn exactly what these workers do.
1. They Determine the Appropriate Way of Lifting a Load
Different loads have different weights. A crane rigger's job is to determine the weight of each load and find a suitable way of lifting it. The crane to be used for hoisting any load should be able to safely support the weight of the load.
The 'load', in this context, refers to the combined weight of the material or object to be lifted and the weight of the rigging equipment. The capacity of the rigging hardware also matters – it should be able to withstand the weight of the material or object to be moved. Another important consideration is the working load limit of the rigging equipment. The equipment should be able to withstand the external forces exerted on them during rigging operations.
Once all the weights and capacities have been identified, the rigger must then decide on how to lift the load so that crane and rigging accidents can be prevented.
2. They Identify and Assess Workplace Hazards
As rigging operations involve lifting loads at heights, the risk of an accident happening on the job is always inherent. Crane riggers are responsible for identifying and taking steps to minimise hazards that may arise during rigging work.
Some common examples of workplace hazards during rigging operations include contact with energised overhead electricity lines, swinging and rotating loads and falling loads.
Rigging operations should be stopped when hazardous wind conditions set in. While the crane and rigging equipment may be within the required weight and load capacity limits, windy conditions may cause an overload, putting the entire crew in harm's way.
3. They Inspect All Rigging Equipment Prior to Use
In order to minimise hazards arising from the use of questionable rigging systems, riggers pre-inspect all rigging equipment to determine their suitability for the job. Any faulty component must be replaced and properly discarded.
4. They Communicate With Crane Operators on Safety Protocols
Working from the operator's cabin, crane operators need someone on the outside to help them ensure safe crane and rigging operations. This is where riggers come in – they can use two-way radios, signals or other agreed-upon means of communication to help crane operators perform their job safely.
Using trained and experienced riggers is vital to ensure a safe crane and rigging operation. If you don't have competent riggers, you can always hire them.
