It is important to note that the hoisting wire rope used for wire rope hoists and overhead cranes is specially made of extra flexible Improved Plow Steel (IPS). It’s considered superior in durability and tensile strength (bending) to standard, everyday hoisting wire rope.

When properly sized and lubricated, a hoisting wire rope should last for years, even with frequent use. Hoisting wire rope wire rope hoists are recommended for heavy duty applications, high frequency usage, and where long lifts are needed.

Causes to hoisting wire rope

Hoisting wire rope can be damaged easily when it is misused, which will largely lower your working efficiency, and endangers the hoisting safety.

Hoisting wire rope damaged

Why your hoisting wire rope is damaged so easily? The Answer is that most likely as follow:

Hoist operation. There’s a problem with how the wire rope hoist is operated. Hoisting wire rope failure is almost always due to operator error. By design, hoist hook blocks must be raised and lowered straight up and straight down, and the hoisting wire rope cable wraps around the drum, within the grooving, in one layer. In the course of picking up a load, if the operator side pulls the rope by more than about three degrees from vertical, the hoisting wire rope will jump the drum’s grooves.

Once the grooves are jumped, the operator must realize the error and stop using the hoist immediately. To correct the issue, the load must be lowered and the hoisting wire rope must be allowed to return it to the correct drum grooves. If the operator continues to use the hoist with the hoisting wire rope piled up at one end of the drum, the rope gets pinched and the cable can become damaged. Also in the course of usage, if the cable goes slack and the hoisting wire rope jumps over the drum guard, it could get caught between the drum and the shaft, and the hoisting wire rope could fail.

To prevent this problem, we recommend operator training and regular inspection of the unit. Every shift should start with an examination of the rope by lowering the hook all the way down. If the rope is damaged, including even one strand broken, stop the process and get the rope replaced. We recommend keeping spare ropes in stock to avoid downtime and ALWAYS BUY OEM HOISTING WIRE ROPES. If not, your replacement may be the wrong type, grade, or end fitting.
