Anti-entanglement problem of single-beam crane electric hoist rope stuck

Electric hoist is a necessary lifting mechanism for electric single-beam cranes used in enterprise production. In the past, if there is a problem with the rope arranging device and not replaced in time, the wire rope is prone to entanglement. If the electric hoist wire rope of the single-beam crane is entangled, stop using it immediately and straighten out the wire rope in time.

The main steps are as follows:

Remove the motor → cut the wire rope → sort out the messy rope → install the motor → re-thread the rope (new wire rope).

The winding methods of electric hoist wire rope mainly include single-layer winding and multi-layer winding. The single-layer type means that there is a rope on the reel, which is also called a rope guide, which helps to wind the wire rope on the reel neatly and avoid the wire rope from being messy. Multi-layer winding of steel wire ropes is a rope hoist. In order to avoid the slack of the inner steel wire rope, the winding of the first steel wire rope should be carried out under tension. In order to prolong the service life of the wire rope and rope guide, we must strictly follow the requirements in the maintenance manual, and forbid crooked pulling and diagonal hanging. The tighter the wire rope is drawn, the better the winding effect. The advantage of the chaotic rope electric hoist (winding hoist) is that it can save the volume of the electric hoist itself and reduce the cost. It is often used to lift the lifting range with a height of more than 30 meters.

In fact, many electric wire rope hoists now have rope guides. With the help of the rope guides, the rope will not be tangled unless the rope guides are damaged.

What should I do if the electric hoist is stuck?

Rope jams of electric hoists are generally caused by crooked pulling and oblique cranes. Wire rope jamming is one of the common problems of wire rope electric hoists. How can we avoid the phenomenon of wire rope electric hoists?

Aiming at the above problem, after analysis and research, a simple method is adopted to effectively solve this problem. A retaining ring is welded on the inner side of the flange, so as to prevent the wire rope from getting stuck in the appeal part due to various reasons, and at the same time, it does not affect the assembly of the drum and the motor and the performance of the wire rope electric hoist. We have made improvements to some electric hoists. After more than a year of use, we have completely eliminated the problem of wire rope jamming. Even if the rope disorder occurs in the production process, it can only be handled between the shell of the electric hoist and the drum. It can be handled in a short time by simple methods such as traction and increased load. It not only maintains the service life of the equipment, but also does not affect the normal production.

Winding accidents often occur when electric hoists are in use. Especially when the wire rope is stuck in the gap between the drum and the lifting motor, the only way to deal with it is to remove the motor and take out the wire rope. It is time-consuming and laborious, and it also delays normal production. Sometimes in order to maintain production, the steel wire rope is cut off by gas welding, leaving the broken steel wire rope very easy to wear the drum and motor casing, causing greater equipment accidents.

At present, the electric hoist produced by our factory has adopted anti-winding and anti-rope devices, the product failure rate is smaller, and the use is more assured. Welcome to call to order.
