Traveling Block & Hook
Source:SIQUAN|[ 2014-03-05 ] Hits:1121
摘要:
Main features(Traveling block):
●The side plate of traveling block is thick steel plate. Its mass is strong enough.
●When lifting and lowering down an empty elevator, the wire line is in a tension status. It is good for line winding and empty hook lowering speed, and for prolonging the service life of the line. 
●Sheave grooves has been quenched at intermediate frequency to decrease the wearing speed of line. 
●There are double row tapered roller bearings installed in pulley holes, and each bearing has its own lube oil passage. 
●Traveling block sheaves and bearings are interchangeable with that of the matched crown block.

Main features(Hook):
●T
he hook is manly composed of elevator bail, elevator bail seat, barrel, hook body, hook rod and spring etc. In the barrel there are inner and outer springs which can make the pin of standpipe spring up backwards. 
●On the top of the barrel there is a safety positioning device. When lifting an empty elevator, the positioning device can stop the rotation of the hook body.
●When lifting a elevator with drill string, the positioning device no longer can stop the rotation of the hook body; the hook body can rotate freely. 
●The detent device can lock hook body at any one of eight even positions. And the safety pin body of the hook can also be locked by locking deice. 
●For protecting DP connector while breaking out, there is a hydraulic buffer device installed in the hook. 
●A reliable safety device is installed at hook opening. 
●The main load-bearing parts have been inspected by NDT completely.
