Inclined and inclined cranes are very harmful to group hoists. Inclined pulling will affect many parts of the group hoist. When the load of the group crane electric hoist is in the air, and the degree of wear of the hook is in the air, the load will jitter, so that the possibility of the hook hanging off the hook is very high. It is in a slanting state when it is slanted, and it is easy to cause the hook to loosen when the electric hoist of the group crane is hoisted. Unusual lifting will cause the hook to wear easily and shorten the life of the hook. When the load is lifted to the ground, the inclined group crane is suspended in the air, and the load must be shaken, and the shaking will make the load attack the centripetal force and increase the load of the motor. Especially when the shaking direction is parallel to the operating direction of the trolley, the load will be shaken and has corrosion resistance to the thrust and resistance of the electric trolley, so the load of the motor driven by the motor is unstable, that is, the current through the motor is suddenly large and small . The fire may cause the motor to rotate and overheat. Increased noise or even abnormal noise, which may cause the fuse to blow or damage the motor coil. Regarding the damage of the steel wire rope, the cable rope and the guide rope will be squeezed together due to the diagonal pulling and slanting, so that the impulse force between the guide rope and the steel rope is increased, thereby forming the wear and rubbing deformation of the steel rope. When the steel wire rope is damaged, the group hoist electric hoist steel wire rope can easily cause the problem of chaotic slotting and reduce its service life. Therefore, we should not take the risk that it is not important that the cable-stayed sling occurs. When it is found that the electric hoist appears to be pulled diagonally, the number of loads should be reduced immediately. While ensuring power, it is also very important to choose the quality of the group hoist electric hoist. In order to prevent this situation, I will talk about a skew-proof group crane equipment, which is composed of a rope clamp, two welding components and a limiter. The rope clamp is the lowest point of the shell arc welded relative to the center point of the balance wheel. The principle is that it can play a protective role in any direction. Therefore, when planning the component 2, the center hole is planned to be circular, which will make the declination of the reverse inclined cable crane in all directions the same; the travel limit switch contacts. The size of the view point of the rod-type anti-slanting group crane is adjusted according to the actual operating conditions. If the view point size needs to be increased. There are 3 methods: expand the center hole of component 2; lower the sensitivity of the limit switch; the operating principle will set a suitable wire rope deflection angle according to the status of the operation practice, when the skewed slanting viewpoint is greater than the set value At this time, the deflection of the steel wire rope is sufficient to make the edge of the center hole of the component 2 touch the limit contact rod, causing the limit operation.
