API 8A / 8C Oil Rig Equipment Hook Block Assembly Traveling Block And Hook

Oil Rig Equipment Oil Well Drilling Rig API 8A/8C Hook Block

Hook block complies with API Spec 8A/8C. Joining traveling block and hook together reduces overall length and can help satisfying the requirements of top drive operation. The hook block is equipped with the reliable safety devices on the main hook. The main parts are made of high strength alloy steels and are subjected to nondestructive testing. The sheave grooves have been intermediate frequency quenched, which can improve the hardness of the surface, the wearness, and the service life.

Features:

* Joining traveling block and hook together reduces overall length and can help satisfy the requirements of top drive operation.

* The shafts of travelling block are forged with alloy steel and provided with a lubrication hole of bearing for one sheave.

* The grooves of sheave are intermediate frequency quenched so as to improve the surface hardness and prolong the service life.

* The sheaves are equipped with double-row conic roller bearings. Each bearing has its own lubrication channel.

* There is a reliable safety device at the hook,

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

* The hook block assembly conforms to API 8A/8C.
