ZT1-600 bidirectional slack adjuster is mounted on the foundation brake rigging of railway freight wagons. After brake shoe wear or replacement, the unit automatically extends or retracts the screw rod to keep the standard clearance between brake shoe and wheel tread and stabilize brake cylinder piston stroke. It features compact structure and quick mechanical response, excellent vibration resistance and wide temperature adaptability for harsh field environments. It reduces manual gap adjustment, unifies brake stroke of all wagons in train, lessens longitudinal impact and improves railway operation safety. Compliant with TB/T and UIC railway standards, widely used on heavy haul freight rolling stock.

ZT1-600 Bidirectional Slack Adjuster

Application:

This ZT1-600 bidirectional slack adjuster serves as a core component of railway vehicle brake systems. It automatically and bidirectionally compensates the clearance between brake shoes and train wheels, stabilizing braking force and eliminating frequent manual gap calibration. Widely applied to freight wagons, passenger carriages and heavy-duty rolling stock, it adapts to long-distance transportation and high-frequency braking under harsh outdoor conditions, greatly lowering maintenance labor costs and improving overall railway operation safety.
