The TR-B Train Brake Test Bench is a specialized diagnostic station designed for the performance testing of JZ-7 brake system components. It provides a professional testing environment for automatic brake valves, individual brake valves, shut-off valves, relay valves, and distribution valves (main and auxiliary). By utilizing a full pointer pressure gauge display, the TR-B transforms complex brake testing into an intuitive and clear process. This equipment is essential for railway maintenance facilities to ensure the qualified rate of valve loading and to avoid missed or false inspections during routine maintenance.




Comprehensive Valve Testing: Capable of testing the full range of JZ-7 brake machine parts, including automatic, separate, shut-off, and action valves.
Intuitive Monitoring: Equipped with 9 high-precision pressure gauges that provide real-time visualization of the entire braking process, from the train cylinder to the main air cylinder.
Improved Inspection Reliability: Reduces human error and labor intensity by providing clear, measurable data for every stage of the brake test.
User-Friendly Design: Features a cold plate bench with a durable spray-painted finish, independent air source switches, and dedicated power controls for streamlined operation.
Manual Clamping System: Simple and reliable manual clamping ensures quick installation and secure holding of various valve components.
High-Standard Performance: Designed to meet rigorous railway safety standards, improving the overall qualified rate of locomotive braking systems.
