Hydraulic Disc Brake
The hydraulic disc brake system is a mechanical, electrical and hydraulic integrated product, which is an important component of the drawworks.
Main Mechnical Features
1.It can meet the operation requirements of desert, Gobi, tropical and other harsh oilfield field environment.
2.It can realize the functions of working braking, emergency braking, parking braking and over roll protection braking.
3.The hydraulic station has double motor pump sets, double circuits and multiple protection functions, with high reliability.
4.With power failure alarm, low voltage alarm function, high security.
