Whether it is an electric hoist or a chain hoist, it is expressly forbidden to pull it and hang it. Some users say that they have also been slanted and slanted without any accidents. So what are the hazards of slanting and slanting? Let's take electric hoist as an example to introduce the hazards of diagonal pulling and crooked hoisting.

First of all, the oblique pulling of the electric hoist will cause serious harm to the motor. When the load of the obliquely hung object is lifted to leave the ground and suspended in the air, the object will swing, causing the object to produce centripetal force, increase the load of the motor, the lighter motor will reduce the motor speed, self-overheating, the noise will increase or even abnormal noise, the severer will burn Motor coil.
The oblique pulling and crooked crane causes a certain amount of squeeze on the wire rope and the rope guide of the electric hoist, causing the friction between the two to increase, causing the wire rope to be squeezed and deformed or grooving disorder. The rope guide is also prone to displacement, and the screw that drives the stopper is displaced correspondingly, so that the rising limit has an advance or lag action.
Oblique pulling and crooked hanging will also cause certain damage to the electric hoist hook. When the load is suspended in the air, it will inevitably swing. When the swing range is large, the rope sleeve is easy to unhook, and it will also accelerate the dangerous section of the hook and reduce its service life.
Generally speaking, the electric hoist oblique pulling and crooked crane may not only be overloaded, but also cause different degrees of wear and tear on the parts. It is harmful to no benefit. Users are hoped not to have a fluke mentality, and wait until it does appear. I regretted it when the accident happened.

Why is the electric hoist forbidden to pull crookedly?
