Hook Block

 

 

 

 

 

 1.  Joining the traveling block and the hook together reduced overall length to satisfy the requirement of a top drive.

 

2.The shaft of the traveling block are forged with alloy steel and provided with a lubrication hole of bearing for one sheave.

 

3.The sheave grooves are intermediate frequency quenched so as to improve surface hardness and extend service lift of sheaves.

 

4. All sheaves had double-row conical roller bearings and each bearing has individual lubricating channel.

 

5. There is a reliable safety device at the hook.

 

6. The primary-load-carrying parts of the hook are subject to NDE test.

 

7. The hook block conform to API Spec. 8A/8C and API monogram can be used.
