Overhead Crane Electric NHA type Low Headroom Wire Rope Hoist
 
Low Headroom Electric Wire Rope Hoist is the newly developed type which is specific to the box type beam but not the traditional I beam. You can benefit from shock absorption and noise reduction. What's more, the distance for the gauge can be adjusted. this products, by its newly unique design and great originality, have gained a good reputation among users in China and abroad.
1. Reducer
Third-class dead axel helica gear transmission structure is adopted,; gear and gear axel are made of heat treated alloy steel.
2. Control Box
It has device with up an down stroke protection of break off limiter and can cut off main circuit in an emergency,which ensures safe operation of electric block.Electric elements are of long service life and operational safety.
3.Steel Wire Rope
It uses GB******4(6**7*1) hoist steel wire rope which is durable in use.
4. Conical Motor
the hoist motor uses conical motors of relatively stronger starting torque to brake asynchronous motor and does not need extra arrester. the motor s load duration factor is *5%.
