Jiaozuo brake

Electric hydraulic block brake: Using hydraulic electromagnetic blocks instead of long travel block brake electromagnets, there are two types: YWZ (hydraulic push rod) and YDWZ (hydraulic electromagnet). The YWZ type brake is stable, noiseless, and small in size, making it suitable for operating and rotating mechanisms. Due to its slow braking action, it is not suitable for the use of lifting mechanisms to prevent hook slipping. The YDWZ model has good performance in various aspects and does not require frequent adjustments. It only requires a DC power supply.

2. Belt brake: when the overall dimensions are affected and the braking torque is required greatly, the belt brake can be considered. This kind of brake device is commonly used on Mobile crane. The disadvantage of band brakes is their low safety, and breaking the brake band can cause serious consequences.

3. Disc brake: the disc brake is widely used due to its large braking torque, small overall dimensions, large friction area and small wear. Disadvantages of disc brake: the electromagnet coil is easy to heat, impact, noise and parts are easy to be damaged when the temperature rises.

4. The brake ring and brake wheel of the conical brake are both conical, and the conical brake is a part of the conical electric motor. The reason why the rotor and stator of the conical electric motor are designed and made into conical is to obtain a simple and lightweight structure, convenient assembly and adjustment, and inseparable from the electric motor. The conical brake is currently widely used by electric hoists, CD, AS DH electric hoists all use conical brakes.

The hydraulic push rod brake pads for cranes are mainly made of asbestos material with copper wire inside, which is sturdy and not slippery
