Product Overview

The YW-L series electro-hydraulic drum brake is a commonly used braking device for lifting, transportation, metallurgy and other industrial fields. Its mounting dimensions comply with DIN 15435 and JB/T 7021-2006 standards, and technical specifications conform to JB/T 6406-2006 standards. It is typically driven by an electro-hydraulic thruster: when energized, the built-in motor of the thruster drives the impeller to rotate, generating hydraulic oil pressure that pushes the piston and other components to actuate the brake arm, which in turn drives the brake linings to clamp the brake drum tightly to achieve braking; when de-energized, the brake linings separate from the brake drum under the action of the brake spring, releasing the brake. Different models are suitable for different brake drum diameters, with the braking torque range varying accordingly. For example, the YWL200-500A is suitable for a drum diameter of 200 mm with a braking torque of 500 Nm. The standard operating voltage is AC 380 V/50 Hz, and the brake is suitable for continuous (S1) and intermittent (S3-60%, operating frequency ≤ 1200 cycles/h) duty cycles.
