ZWZA Series DC Electromagnetic Drum Brake
Purpose and Main Characteristics：
-
Widely applied to the deceleration and parking braking of mechanical drive units in lifting, transportation, metallurgy, mining, port and dock, and construction engineering sectors.
-
Its mounting dimensions and braking torque parameters comply with JB/ZQ4386-1997, and technical requirements conform to JB/T7685-2006.
Operating Conditions：
- Ambient temperature: -25℃ ~ 40℃
- Relative air humidity: ≤ 90%
- Service altitude: ≤ 2000 m
- No flammable, explosive, corrosive gases or metal-corrosive, insulation-damaging conductive dust in the working environment.
- Operating frequency: ≤ 720 cycles/h
- Power supply: DC 110 V or DC 220 V. An optional DKZ power box is required for an AC 380 V power supply.

Model Designation
ZWZA Series DC Electromagnetic Drum Brakes are primarily used for deceleration and parking braking of various mechanisms in DC motor-driven, DC grid-supplied lifting, port handling and metallurgical machinery. Their use is not recommended for AC motor-driven lifting, port handling and metallurgical machinery. Mounting dimensions and braking torque parameters comply with JB/ZQ4386-1997, while technical requirements conform to JB/T7685-2006. This series is designed as an upgrade replacement for the existing ZWZ Series legacy products.
