Some of the drum brakes have a compensation device and brake cylinder. The drum brake is used for automobile crane QY12T, QY16T, QY20T, QY25T, QY30T, QY50T and QY75T, etc., big tonnage cargo truck, pavers, graders, road rollers and excavators and so on. Both the brake shoe and brake bracket use the nodular cast iron, and the friction plate employs the non-asbestos materials. The processing line including processing center, CNC lathe and special purpose machine tool is used to process the brake shoe and brake bracket. The traditional riveting technology is used to process the friction plate and brake shoe and can achieve reliable linkage. Using the milling and grinding process, the drum brake features high precision and sound performance. There are more than 20 kinds of products for you to choose.

The drum brake is a brake in which the friction is caused by a set of brake shoes or pads that press against a rotating drum. It is an important part of the engineering equipment, and has low price and good braking performance. The brake shoe and brake drum of the similar drum brake are more prone to deformation under high temperature, thereby decreasing the braking efficiency. In order to avoid this problem, our drum brake equipped with a unique automatic self-adjuster is made of new materials with high temperature stability and processed by using precision CNC machining technology. This drum brake has pneumatic and hydraulic two brake mode for operation, and is widely used in the brake system of QY12T, QY16T, QY20T, QY25T, QY30T, QY50T truck cranes, large tonnage dump trucks, road rollers and other heavy machinery. The adoption of new technologies and new materials has dramatically increased the product performance, so our drum brake is now well received by customers both at home and abroad.
