2.Application:
●YW-E Electro-hydraulic drum brakes are mainly used for large/middle outdoor crane with excellent deceleration braking and storm braking performance. This brake can also used on large and middle special cranes to assure stable deceleration braking and maintenance braking. It is also good choice to use on belt transport vehicle.
●YW-E series brake is two-step braking device. In the first step, a minor torque is exerted to make stable deceleration braking. The second step will start when the device stopped; a bigger torque is exerted to realize reliable maintenance or storm braking. The second step can be adjusted by damping single way throttle in cylinder circuit(with 1-15 seconds)

3.Main Feature:
● The overall shape of the structure brake pads mounted on the card, the replacement is very convenient, fast, with semi-metallic (asbestos-free) of hard and semi-rigid, soft (including asbestos, asbestos-free), the braking of different materials pad for the user to select.
● Interlocking shoe clearance balancing device and shoe auto-aligning device constantly equalize the clearance of brake shoes on both sides and make adjustment unnecessary，completely avoiding brake lining one side sticking to brake wheel;
● Braking by spring power;
● Lifting by thruster;
● Brake torque adjustable;
● Brake closes in case of power failure (Fail-Safe Principle);
