Drilling Rig Hook block

Drilling Rig Hook block 1) Joining traveling block reduces overall Length 2) Conform to API Specification 8C PSL1 and API

 Drilling Rig Hook Block

Hook Blocks Design Features:

1. Joining traveling block and hook together reduces overall Length and can help to satisfy the requirements of operating a top drive.

2. The hook blocks conform to API Specification 8C PSL1 and API monogram can be used

3. Critical driving parts uses advanced heat treatment process such as cementation, can satisfy process requirements of overhead drilling.

4. Before leaving factory all productions have passed depth flaw detection.
