Crane riggers are professionals that work alongside crane operators to ensure onsite safety. When hiring a crane, you should ask the company to provide experienced and qualified crane riggers. Below is a comprehensive guide on crane riggers.
Types Of Crane Riggers
Crane riggers can be categorised according to their licences. A basic rigging (RB) licence allows the individual to perform rigging works such as directing the crane operator and inspecting the crane's lifting gear. An intermediate rigging (RI) licence permits the professional to conduct basic rigging works, install tilt slabs, operate self-climbing hoists and dual lifts. An advanced rigging (RA) licence allows the rigger to conduct intermediate rigging works, install and inspect flying foxes, shear legs and derricks.
Hiring A Crane Rigger
The crane rigger must be experienced. Preferably, they should have dealt with similar or larger cranes in the past. The rigger should have excellent communication, problem-solving and leadership skills. At the site, they will work with employees and the crane operator to ensure safety.
The Work Of Crane Riggers
Below are the functions of crane riggers:
The rigger will assess the following when inspecting the crane:
- The presence of corrosion, cracks and bends along the frame of the crane.
- The condition of the crane's hydraulic system. The rigger will check the fluid levels and assess the system for signs of leakage.
- The condition of rollers, gears and bearings. For instance, they might require lubrication to prevent friction.
- The functionality of the crane's electrical system. For example, blown fuses and scorched connections are considered red flags.
- The condition of the wire rope and the drums. Ideally, the rigger will ensure the wire rope can handle loads at the site.
Crane Installation and Operation
The rigger will help set up the crane at your site. They will assess the site conditions and advice on a suitable place to install the crane. You may need to use outrigger pads if the area has soft soil. During crane operation, the rigger will help the operator identify blindspots. Besides, they will instruct the operator when and where to move the boom.
Enforcing Safety Standards
The rigger will help ensure safety at the site. For instance, they will conduct weather forecasts to predict windy conditions and storms. Additionally, the rigger will check load charts to ensure the crane does not exceed its weight limits. They will also ensure site personnel have the required protective clothing.
A crane rigger is a vital component of crane operation. They ease the work of the operator and ensure safety at the site.
