Core Advantages
Two mainstream series for different demands
YWZ4: Cost-effective basic model with built-in equal clearance linkage, stable performance for conventional medium-load working conditions.
YWZ8: Upgraded version with automatic wear compensation, no frequent manual gap adjustment, ideal for high-frequency heavy-duty continuous operation.
Freely adjustable braking torqueGraduated scale on the main braking spring tube allows intuitive adjustment of spring pre-compression, matching torque requirements of different loads.
Low daily maintenance costSelf-lubricating hinge bearings eliminate regular greasing; plug-in snap friction linings can be replaced quickly without disassembling the entire brake frame.
Diverse matching & customizable optionsCompatible with standard ED, YT1 electro-hydraulic thrusters; BEd flameproof thrusters optional for coal mines and chemical explosive hazardous zones. Vertical standard mounting and custom horizontal transition brackets available for narrow installation space. Dustproof, rainproof and anti-corrosion coatings are provided for coastal open-air sites.
Complete safety accessoriesOptional manual emergency release lever and travel limit switches to feed back brake open/closed signals for PLC safety interlock protection.
Main Application Scenarios
Overhead travelling crane, container gantry crane, port yard trolley, metallurgy heavy transport cart, mining belt conveyor, construction tower crane and all heavy-load lifting & transportation machinery.
Working Conditions
Ambient temperature: -20℃ ~ +50℃Standard power supply of thruster: AC380V; AC220V, 660V, 1140V customizableExplosion-proof versions meet Ex d I (coal mine) and Ex d IIB T4 (chemical plant) standards.
