Features of the travelling block
1. Side board is thick steel plate and heavy enough to keep wireline tight during lifting and lowering for easy spooling and no-load lowing of the hook and longer wireline service life.
2. Sheave groove subject to intermediate frequency quenching for better case hardness and longer wireline service life
3. Sheave is equipped with double cone roller bearing, each has independent oil passageway
4. Alloy steel shaft with oil port to each sheave bearing
5. Heavy-duty wireline guard
6. High strength wireline elevator
7. The sheave and bearing are interchangeable to those of mated crown block
8. Built to API 8A, have the certificate of authority to use the official API monogram
