The hazards and preventive measures that electric wire rope hoists may cause during diagonal pulling and lifting are as follows:

The hazards of diagonal pulling and suspension

Equipment damage:

Diagonal pulling and lifting can cause uneven stress on the steel wire rope, which may lead to increased wear and even breakage.

Long term diagonal suspension can cause abnormal stress on the transmission mechanism of the hoist, which may lead to damage to internal parts and even the entire hoist being scrapped.

Diagonal suspension may also cause damage to the cable feeder of the electric hoist, affecting its normal operation.

Personal injury:

When inclined hoisting, the equipment may suddenly lose control or become unbalanced, which can easily cause personal injury to operators or nearby personnel.

preventive measure

Reasonable design:

When designing an electric hoist, full consideration should be given to its working environment and conditions, and its structure and performance should be reasonably designed to reduce the possibility of cable-stayed suspension.

Installation and usage specifications:

The installation and use of electric hoists should strictly comply with relevant regulations and standards to ensure their stable installation and correct use.

Avoid using electric hoists in situations where diagonal lifting is not allowed, and ensure that they work within the specified working range.

Use anti diagonal lifting device:

Special anti diagonal lifting devices can be used, such as using steel wire ropes to generate a deviation angle to activate the limit switch, automatically disconnect the lifting contactor, and limit the lifting.

This device is usually composed of rope clamps, welding components, and limiters, which can effectively prevent the occurrence of diagonal pulling and lifting.

Regular inspection and maintenance:

Regularly inspect and maintain the electric hoist, promptly identify and deal with potential hazards that may cause inclined suspension.

Check the wear of the steel wire rope, whether the transmission mechanism of the hoist is normal, and whether the cable puller is damaged.

Operator training:

Operators should receive professional training to understand the structure, performance, and usage of electric hoists, and master the correct operating methods.

Operators should strictly follow the operating procedures, strictly prohibit diagonal pulling and lifting, and ensure the safe operation of the equipment.

Environmental control:

Control the working environment and avoid using electric hoists under adverse conditions such as strong winds and vibrations.

In situations where inclined suspension may occur, necessary protective measures should be taken, such as setting up guiding devices.
