Key Upgraded Advantages
Auto Equal Clearance & Auto Wear Compensation (Core Upgrade)Built-in linkage balancing mechanism maintains identical gap between two friction linings and brake drum automatically during operation. No frequent manual gap adjustment, completely avoids unilateral lining dragging, uneven wear and overheating failure. As linings wear, the structure self-compensates clearance to keep stable constant braking torque long-term.
Ultra-Low Maintenance Structure
All hinge pivot points fitted with self-lubricating bearings, no regular grease refilling required;
Snap-in plug-in non-asbestos friction linings, replace quickly without disassembling the whole brake frame, cutting maintenance time by over 60%;
Braking spring with visual torque scale, read and adjust rated braking torque directly without complex measurement.
Reliable Fail-Safe Safety PerformanceStandard power-off emergency braking design: when power failure, sudden stop or equipment fault occurs, preloaded heavy-duty springs push brake shoes to lock the drum tightly, effectively prevent cargo falling or trolley sliding. Optional travel limit switches feed back full-brake/full-release signals to PLC for safety interlock control.
Matching & Customization FlexibilityMatched with ED/E301 standard electro-hydraulic thrusters; BEd flameproof thruster versions available for underground mines and chemical flammable hazardous zones. Support vertical standard mounting & custom horizontal transition brackets for narrow installation space. Anti-corrosion coating, dust/rain protective covers and semi-metallic high-wear linings are optional for coastal salt fog, high-dust cement plant and high-frequency heavy-duty working conditions.
Wide Application Scenarios
Overhead crane, gantry container crane, yard travel trolley, metallurgical transfer cart, mining conveyor, tower crane, belt conveyor emergency stop and all heavy-duty lifting & transportation machinery.
