THE MODEL Of YWZ4 ELECTRO HYDRAULIC DRUM BRAKE

Drum brake is a typical radial brake. It includes a rotating cylindrical brake drum and a brake bottom plate, and brake shoes made of cast iron, steel or aluminum are connected with the brake lining.

When braking, the brake shoe is pushed out by the camshaft, wedge device or wheel brake cylinder, squeezing the surrounding brake drum to achieve the purpose of braking. After being used for a long time, the brake will wear out. At this time, manual or automatic turnbuckles will work to correct the displacement and compensate for the wear.

External beam drum brake can also be used for lifting equipment and windlass.

The maximum adjustment coefficient of braking torque of drum brake is five. Due to the good internal amplification function, only a small force is needed to activate the brake.

Internal tension drum brakes have good corrosion resistance, which is why they are often used in vehicles on construction sites. They are the most common brakes for heavy cranes.
