DYW200‑224 Explosion‑Protected Electro‑Hydraulic Drum Brake is a flame‑proof fail‑safe safety brake specially designed for hoisting and conveying machinery operating in explosive‑gas hazardous environments. It follows the working principle of spring‑applied and hydraulic‑release. Under power‑off condition, high‑power compression springs push the brake shoes to clamp tightly against the brake drum, realizing reliable emergency braking and parking braking. When energized, the matched certified explosion‑protected electro‑hydraulic thruster produces thrust to pry open the brake shoes and release the brake drum, so that the host equipment can run normally.
The complete brake unit is equipped with qualified flame‑proof electro‑hydraulic thruster and meets corresponding explosion‑proof safety standards. It effectively isolates electrical spark hazards and can operate safely in coal mines, chemical plants, petrochemical facilities and other sites with flammable and explosive gas mixtures. Adopting high‑friction wear‑resistant brake shoes, the brake maintains stable braking torque under heavy‑load and frequent cyclic braking conditions. The heavy‑duty cast‑steel frame provides superior structural rigidity and impact resistance for rigorous industrial working conditions.
The clearance between brake shoe and brake drum can be easily adjusted on‑site. Worn brake shoes can be quickly replaced without complete disassembly of the brake assembly, shortening maintenance periods and reducing equipment downtime. All hinge transmission positions are precision‑machined to guarantee sensitive, smooth and consistent mechanical response during long‑term operation.
As an indispensable safety‑critical braking component, DYW200‑224 explosion‑protected electro‑hydraulic drum brake is extensively installed on overhead cranes, gantry cranes, electric hoists and belt conveyors serving explosive hazardous working zones.
