Design Features

Joining the travelling block and the hook together reduces overall length to satisfy the requirements of a top drive.

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 bearing has its own lubrication channel.

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 Spec 8A/8C.
