When it comes to hoists, wire ropes are one of the components that are replaced most often.
They can be compared to tires on a car. Wire ropes are prone to wear and tear over time and with continued use. The more often they’re used and the heavier their loads, the sooner they wear. They should last their full expected life if they are properly maintained. However, it’s important to note that wire ropes are susceptible to being ruined due to improper installation or external damage caused by improper operation. Continue reading to find out more about replacing hoist wire ropes.
Purchasing Hoist Wire Ropes
Using a generic wire rope to replace a damaged or worn rope can be dangerous because the rope being replaced may already be the wrong size or type if it isn’t the original rope. It’s also important to mention that identifying the correct type, size, and length of wire rope needed can be tricky.
Replacement wire ropes should be purchased or sourced from the original manufacturer to ensure that the correct rope is being used for the hoist. The installation of the wire rope is a crucial task. Whoever installs the new wire rope needs to be sure no twists are introduced into the rope while maintaining the hoist’s proper reeving.
Replacing Hoist Wire Ropes
Load test requirements are excluded when it comes to the replacement of wire rope or chain for underhung hoists. This is because the manufacturer should have already tested the wire rope or chain during the production process. To properly check lifting and lowering function, brake operation, and to check limiting devices, the technician should perform a test without a load attached. Breaking in the rope beforehand is recommended by some wire rope manufacturers. Once the rope has been installed, and a light load has been attached (following manufacturer’s recommendations), it’s recommended that you run through 20-25 lifting and lowering cycles at a reduced speed, gradually increasing the weight up to full capacity if possible. Doing this will allow the rope to adjust and properly seat itself. After this procedure is followed to break in the wire rope, secure the hook block and disconnect the rope end to relax or correct any possible torque or twists that may have developed during the new installation and break-in.
