Product Details

Specifications

1.Complies with API 8A and SY/T5527 specification.
2.The pulley can exchange with the matching crown pulley.

1.Drilling rig traveling blocks is one of the lifting equipments for petroleum drilling rig and workover rig with the integral design,which can shorten the length between traveling block and hook, perfectly meeting the traveling space for lifting system.

2.Drilling rig traveling blocks can be in accordance with Spec 8C PSL1.

3.The advanced heat treatment processes such as carburetion, etc. is used on some crucial driving components with high strength and long service life.

4.The sheave grooves are intermediate frequency quenched so as to provide surface hardness and extend service life ofsheaves.
