Core Competitive Advantages
Built-in interlocking equal clearance structure (Core Highlight)
Patented balance linkage automatically maintains identical gap between two brake shoes and brake wheel all the time. No repeated manual gap calibration needed, thoroughly eliminate unilateral lining friction dragging, local overheating and uneven abrasion, double friction lining service life and reduce spare parts cost for factories.
Power-free labor-saving foot hydraulic control, spring auto reset
Complete independent hydraulic pedal system, no electricity, air compressor or external hydraulic station required, fully adapt to mobile, outdoor and mining equipment without stable power supply. Optimized hydraulic force amplification design reduces pedal operation strength, release foot pressure and the brake automatically resets, no need to keep stepping for long time, effectively relieve operator fatigue in long-shift work.
Smooth stepless modulated braking, stable medium-duty performance
Hydraulic pressure outputs linear and uniform clamping force, realize soft cushioned slow deceleration or emergency stop according to pedal depth. Effectively avoid heavy cargo swing, trolley collision and conveyor material backflow; large-area non-asbestos friction lining ensures stable torque without thermal attenuation under frequent continuous operation, suitable for 3–10 tons medium-load equipmentZhongyuan ....
Ultra-low maintenance modular design
All swing hinge points equipped with maintenance-free self-lubricating bearings, cancel regular grease filling work;
Snap-in plug-type friction linings, replace without disassembling the whole brake frame, save over 60% maintenance time;
Sealed dustproof spring tube prevents workshop dust, mine debris and humid air erosion, reduce component failure rate;
Visible graduated scale on spring tube for intuitive stepless braking torque adjustment to match different load weights.
Reliable emergency backup safety function
Serves as dual safety protection for all lifting and conveying machinery. Once the main electromagnetic or electro-hydraulic brake malfunctions due to power cut, circuit damage or oil leakage, workers can immediately step the TWZ(B) foot brake to lock equipment, prevent major safety accidents such as load falling and trolley sliding. It can also be used as auxiliary windproof parking brake for unattended outdoor small gantry cranes.
Diversified customized matching options
Complete specifications TWZ-200/TWZB-315 and other torque models to cover light & medium load demands. Explosion-proof versions available for underground coal mines and chemical flammable hazardous workshops. Anti-corrosion salt-fog coating and rainproof housing optional for coastal port high-humidity environments, standard horizontal installation, customized transition brackets adapt narrow crane slewing space layout, fully comply with JB/T6406 industrial brake standardZhongyuan ....
