A chain is only as strong as its weakest link as the saying goes. The same can be said for crane operation and the type of wire rope used in lifting. Breaking strength, rope cores, rope diameter, and other factors all play a part in which wire rope should be used for each lifting operation.
Generally speaking, all wire rope should have a lifting capacity of five times that of what’s being hoisted. When considering which type of wire rope to install on a crawler crane, all-terrain crane, hydraulic truck crane, and so forth, think about what the job entails.
Swage rope has smoother sides ideal for tower cranes while synthetic rope is found commonly on boom trucks. Each has specific advantages for different situations. As always, if you’re unsure which wire rope to use, always refer to the original equipment manufacturer’s (OEM) specifications.
Before any lifting job, all gear should be inspected to ensure a safe lift, including crane wire rope and all rigging tethers. If you see frayed rope strands, reverse bends in the rope, or any other damage to the rope, make sure it is replaced before any lifting occurs.
This includes connections between the ropes and any rigging connections attached to the rope. When working with 100 tons 100 feet in the air, safety factors simply cannot be overlooked. Properly sized rope sheaves and other factors will make sure you get the proper service life out of your equipment.
There are a few different ways to perform wire rope installation. Pulling the new rope through with the old rope is common when working with larger cranes. It is advisable to use a rotation-resistant rope or a smaller diameter rope during this process.
As factory-trained Link-Belt technicians, Triad Machinery will use the safest, most cost-effective way to install wire rope on your crane. This could mean pulling the wire rope through the system to the drum or in reverse order. There are advantages and disadvantages to both methods.
We offer installation at any of our six locations as well as bringing wire rope to the site for installation to save time. After a quick conversation, one of our service trucks will arrive on-site to install the new rope. Our fully-equipped trucks are ready to help with most other repair jobs in the field as well.
