Description
Electric hydraulic thruster operated drum brakes are widely used for deceleration and parking brakes of mechanical driving devices in lifting, metallurgy, mines, ports, docks, and construction. Some additional functions can be realized by adding additional devices: the manual release device releases (opens the brake) or closes (closes) the limit switch, which can realize the signal display or interlock protection of whether the brake is normally released or closed. The pusher with the descending delay valve can be used to realize the delay closing of the brake.
The main features of YWZ4 series brake:
1. The performance is safe and reliable, the braking is stable, and the action frequency is high;
2. The main movable hinge points are equipped with self-lubricating bearings, which have high transmission efficiency and long life. No lubrication is required during use;
3. The interlocking retreat equalization device and the pad automatic positioning device can always keep the retreat distances of the pads on both sides equal without adjustment, completely avoiding one side of the brake pad floating on the brake wheel due to uneven retreat phenomenon;
4. The brake pad is a snap-mounted integral molding structure, which is very convenient and quick to replace. It is equipped with semi-metal (non-asbestos) hard and semi-hard, soft (including asbestos, non-asbestos) and other brake materials of different materials The padding is for users to choose.
