Crane riggers work alongside the crane operator to ensure site safety and prevent potential accidents. Below is an extract discussing the work of crane riggers and the considerations to make when hiring a crane rigger.
The Work Of A Crane Rigger
Crane riggers assist in setting up the crane. They conduct a site inspection to understand the prevailing ground conditions and determine an appropriate location to set up the crane. They also conduct regular inspections to ascertain the condition of the crane. They test the functionality of the hydraulic and electrical systems, assess the wire ropes, crane frame, boom, and outriggers. In addition, they will also review regular crane maintenance such as lubricating the moving parts.
Riggers also formulate a safety protocol to prevent accidents. For instance, they will inform site personnel how the crane will move to ensure they do not get hit by moving components. Additionally, they identify blindspots and ensure that the crane is not overloaded. Likewise, they attach loads to the hook and signal the operator when raising or lowering the crane. Besides, they will inform the operator of hazards such as strong winds and storms.
In addition, riggers will prepare documentation. At the end of each shift, they detail any problems they may have encountered and any repairs that the crane might require.
Hiring A Crane
You should assess the required work to determine the crane rigger qualifications. For example, a crane rigger with a basic rigging (RB) licence can perform dogging works and light rigging such as the erection of structural steel, installing safety nets and the operation of mast climbers. On the other hand, an advanced rigging (RA) licence allows the rigger to conduct complex tasks such as rigging sheer legs, dredges and gin poles.
Once you know what you will require from the rigger, inquire about their availability. Ideally, they should be available from the start to the end of your project. Remember, they will oversee the installation and operation of the crane. Besides, the rigger will be the point person if the crane develops problems while at your site. Ideally, the crane rigger should be personable with excellent communication skills. These skills are especially important since they will be in constant communication with all site personnel and the crane operator.
Most crane hiring companies will have riggers to help in the installation of their cranes. However, if this is not the case, conduct some internet research and seek referrals to identify reputable and experienced riggers in your locality. As a rule, the rigger should have a high-risk work licence and adequate insurance coverage. Contact a rigging company for more information.
