Built-In Equal Clearance Balance Linkage YWZ5 Explosion-Proof Brake, Uniform Wear Extend Service Life Of Friction Linings

 

Core Competitive Advantages

Standard universal installation dimension, easy equipment renovation (Core Highlight)

Mounting hole spacing, center height and torque parameters consistent with ordinary non-explosion-proof YWZ5 brake. Customers can directly replace original common brakes without cutting or modifying mounting base, greatly shorten transformation construction cycle and engineering cost. Perfect choice for old production line safety upgrade projects with explosion risk.

Interlocking equal clearance balance linkage

Built-in synchronous balance mechanism automatically maintains uniform gap between two brake shoes and brake wheel. Effectively eliminate unilateral friction lining dragging, local overheating and uneven abrasion caused by long-term vibration, prolong friction block service life and reduce spare parts consumption for hazardous enterprises.

Support matching ED series non-immersed explosion-proof thruster

Cooperate with ED flameproof thruster adopting non-immersed motor design, motor winding fully isolated from hydraulic oil, avoid common motor burnout failure of immersed explosion-proof thruster. Support 0–180° multi-angle installation, adapt narrow internal layout of explosion-proof cranes and conveyors.

Optional automatic friction lining wear compensation device

As friction pads wear gradually, the compensation structure automatically adjusts stroke to keep stable braking torque. No repeated manual gap inspection and adjustment, reduce frequent maintenance operations in hazardous environments and improve workshop operation efficiency.

Passive spring fail-safe safety protection

High-strength alloy springs provide stable static braking torque. When power outage, circuit fault or hydraulic failure occurs, brake instantly locks brake drum, prevent hoist cargo falling, belt conveyor reverse sliding and crane trolley drifting, meet mandatory safety standards for equipment operating in explosive atmosphere.

Low maintenance modular construction

All swing hinge points adopt maintenance-free self-lubricating bearings, eliminate periodic manual greasing work;

Plug-in snap-on non-asbestos friction linings, can be replaced without complete disassembly of brake frame;

Thickened cast steel integral frame with anti-corrosion coating, adapt chemical corrosive gas, mine dust and humid working conditions;

IP54 sealed structure, dustproof and splash-proof, effectively prevent debris intrusion affecting braking performance.

Diversified customized configurations

Complete specification range YWZ5-160/B30 up to YWZ5-710/B500 covering light to heavy load torque demands. Support ExdⅠMb and ExdⅡB T4 dual explosion-proof grades; AC660V special voltage explosion-proof thruster optional; travel limit switches can be added for PLC signal interlock feedback; anti-salt fog coating optional for offshore platform and coastal chemical plant equipment.
