It is important to note that the hoisting rope used for 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 rope.

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

Causes to hoisting rope

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

Why your hoisting rope is damaged so easily?

The Answer is that most likely as follow:

Hoist operation. There’s a problem with how the Rope hoist is operated. Hoisting 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 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 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 rope must be allowed to return it to the correct drum grooves. If the operator continues to use the hoist with the hoisting 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 rope jumps over the drum guard, it could get caught between the drum and the shaft, and the hoisting 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 ROPES. If not, your replacement may be the wrong type, grade, or end fitting.

• For maximum safety, the hoisting rope must be replaced when even one strand of wire is broken. Refer to OSHA guidelines for construction (1926.1413) for more defined instances of deficiencies.
• Broken strands may be detected by allowing the hoisting rope to pass through a gloved hand holding a rag. The broken strand will catch on the rag.
