Electric wire rope hoist slanting pull hazards
In the use of electric wire rope hoist often found when the electric wire rope hoist pull slanting hanging, but very few people know that this is harmful to the machine, let's say!
Electric wire rope hoist and its accessories are the main part of the lifting mechanism of single-beam crane. The slanting tension and slanting crane in lifting load will cause the following hazards to electric wire rope hoist and its accessories:
The harm of motor when the tilt hanging load lifting hanging in the air to leave the earth, load must be swing, swing load causes centripetal force, increase the load of the motor especially swing direction with the car running in parallel to their direction of load will swing through repeated a thrust and drag acting on the electric trolley, make the motor to drive the car when the load of big is small, namely through the motor current is big and small, light person to lower the speed of the motor, its overheating, the abnormal noise, noise increases even the person that weigh can burn out the fuse of or damage to the motor coil.
The damage to the wire rope is caused by the extrusion of the wire rope and the guide wire, which increases the friction between the guide wire and the wire rope and causes the wire rope to wear and crush.
When the guide device is damaged, the wire rope is easy to be out of groove disorder, reducing its service life. Wear on the hook when inclined hoisting load is in the air, the load must be swing, when the oscillation amplitude is bigger, sling chain or wire rope sling rope will be on the hook hook the dangerous section of the possibility of repeated slip phenomenon suspension slanting decoupling, tilt hanging hook and rope hanging load when also in the tilt state when lifting load, noose easily decoupling, the decoupling, the noose would also be friction with the hook, over time will speed up the hook dangerous section wear and reduce its service life.
So in the discovery of electric hoist slanting pull slanting to reduce the number of loads in a timely manner, to ensure the working efficiency while ensuring the quality of electric wire rope hoist machine
