MWZ brakes are DC power 220V rated voltage
Special requirements can be discussed in order.




2.Application:
ZWZA ZWZB series of DC electromagnetic drum brakes is mainly used for the lifting of the electromagnetic and DC drive or DC power grid, the deceleration of the various agencies in the port handling and metallurgical machinery and parking brake for a variety of exchange-driven crane, port handling and metallurgical machinery is not recommended to use.




MWZ electromagnetic drum brake is complied with JB/ZQ4388-86 standard
3. Main Feature
1) the main fixed hinge point equipped with self-lubricating bearings, high transmission efficiency, long life, the use of the process without lubrication;
2) Interlocking clearance balancing device can always keep both sides of the shoe clearance equalization, be completely avoided due to retire from the uneven brake pads at the side of sticking to brake the wheel phenomenon;
3) the brake pads for the card installed, the overall shape of the structure, 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;
4) Brake spring arrangement in the square tube with a ruler, users can easily read out the braking torque value, which eliminates the trouble of measuring and calculating.




4. Standards compliant
1, ZWZA series of DC electromagnetic drum brake connection dimensions and braking torque parameters in line with JB/ZQ4388-86 standards, technical requirements in line with the JB/T7685-2006 standard. This series is mainly used to replace the original the ZWZ a series of old products;
2. Series of DC 2, ZWZB of electromagnetic drum brakes comply with GB6334-86 standard connection dimensions and braking torque parameters and technical requirements to meet the JB/T7685-2006 standard. This series is mainly used to replace the original ZWZ3, ZWZ3A series of old products.
