If you plan to undertake a major construction project, you certainly in need crane riggers. Your project will involve handling heavy loads that you cannot carry by hand. Investing in a crane and using riggers to move such loads is both economical and safe. Unfortunately, this is not the kind of activity you do every day, and it helps to read some information on how you can go about it. The following piece lays out the basics of crane rigging to help you during your operations:
Get the Right Crane
Rigging activities depend on the particular crane that you choose for the project. It is critical to balance the crane, riggers and the load in question for the operators' efficiency and safety. Today, there are different types of cranes available in the market. The rule of thumb would be to use a mobile or truck-mounted crane for relatively lighter loads. Heavy-duty cranes will come in when the loads are extremely heavy.
Understand Your Wire Rope
Wire ropes are the mechanism used by the crane to do the actual rigging. They wrap around the load and move through strong pulleys that hoist your load from one point to the other. These ropes have three fundamentals you need to know. The first one is the fibre, which is can be made from sisal or synthetic material. Synthetic is the best option. Secondly, there is a strand. These are the individual members that assemble to form the solid cable. Lastly, you have an independent wire rope that supports the main wire rope components.
Ensure that you protect your whole wire rope assembly with softeners, especially when hoisting over corners and sharp bends. It would also help if you ensured that the rope lay equals the arc's length to prevent damage to the rope.
Rope Fatigue Resistance When Rigging
Fatigue refers to a degradation of the metal components that make up the rigging rope. When fatigue sets in, there is a high risk of the rope snapping and releasing the load unexpectedly. The results will be catastrophic. Your ropes need high fatigue resistance, meaning that they can bend multiple times under stress. The stress results from operational scenarios like running over a sheave when hoisting the load. Refrain from bending the ropes over heaves and drums, especially when the rope has a small diameter that kinks the wires. These are some of the operational reminders you need for your team as you rig loads on your site.
