YW-L200/E23 Electro-Hydraulic Drum Brake is a normally closed delay-release braking unit equipped with ED23/5 electro-hydraulic thruster. Its unique adjustable delay release function buffers startup shock and restrains cargo swing during equipment startup. Meanwhile, the spring fail-safe design ensures automatic emergency braking upon power cut for reliable safety protection.
Built-in interlocking equal-clearance mechanism extends the service life of friction linings, and self-lubricating hinges reduce routine maintenance workload. Flexible adjustment of braking torque and delay time makes this brake an ideal choice for overhead cranes, gantry crane travel systems and industrial conveying machinery demanding stable and smooth operation.
YW-L200/E23 Electro-Hydraulic Drum Brake is a specially optimized normally closed delay-release brake matched with ED23/5 electro-hydraulic thruster. Distinguished from conventional YWZ standard brakes, this model adopts an integrated adjustable delay release structure. When the lifting or traveling equipment is started, the brake maintains the braking state for a preset period before releasing, which effectively buffers startup impact and suppresses cargo swing, greatly improving operation stability.
It retains spring fail-safe performance: once power supply fails, the built-in compression springs will instantly actuate braking to prevent equipment drifting and load falling. The interlocking equal-clearance linkage structure keeps uniform clearance between brake shoes and brake drum, avoiding unilateral friction lining dragging, overheating and uneven wear. All pivot joints are equipped with self-lubricating bearings to eliminate frequent manual greasing and lower long-term maintenance costs.
Both braking torque and delay release time can be flexibly adjusted to fit diverse working conditions. Manufactured in compliance with JB/T6406 industrial standards, the brake features a high-rigidity cast steel frame with excellent vibration resistance for frequent start-stop cycles. Widely applied to overhead cranes, gantry crane travel mechanisms and metallurgical conveying machinery that require smooth startup and anti-swing control.
