Products 

Hydraulic power-block brakes are widely used in appliances, metallurgy, mining, ports, terminals, construction machinery, such as mechanical drives or slow down the parking brake. Safe and reliable performance, braking smooth, high-frequency motion. The main point swing hinges with self-lubricating bearings, drive efficiency, long life in use without lubrication.
Standard JB/ZQ4388-1997 installed with the standard size. According to the users need to install the brake pad has two forms: riveting and plug-in (when ordering).
