Unit Brake Replacement Tooling – Product Description

Yunxin Intelligent Equipment (Chengdu) Co., Ltd. , a National High-tech Enterprise certified since 2019 and holding ISO 9001 and AAA credit ratings, has developed a specialized Train Unit Brake Replacement Tooling to address the critical challenges of brake unit maintenance in railway and metro operations. Designed for electric locomotives, diesel locomotives, and metro vehicles, this tooling enables the safe and efficient removal and installation of unit brakes—vital components mounted on bogies for tread air braking. Given that a single unit brake can weigh up to 75 kg and conventional replacement requires at least two workers operating in a maintenance pit, our tooling offers a transformative upgrade in both safety and productivity.

Innovative Structural Design

The tooling features a rotating assembly that allows the lifting hook to be repositioned as needed. A limit mechanism on the mounting frame restrains the lifting cable, preventing excessive sway during hoisting and lowering. This stabilizes the unit brake throughout the operation and protects workers from accidental impact caused by swinging loads. An adjustable lifting rod and connecting rod accommodate various hook positions, ensuring compatibility across different locomotive and metro vehicle models.

Enhanced Operational Safety

The design effectively eliminates the safety risks associated with traditional brake unit replacement, where sudden spring ejection and heavy manual handling often led to injuries. Our tooling provides stable, controlled lifting and precise positioning, significantly reducing the physical strain on maintenance crews and minimizing the potential for accidents.

Improved Maintenance Efficiency

By streamlining the replacement process, the tooling substantially reduces labor hours and downtime. It allows a single operator to perform tasks that previously required multiple workers, making it an ideal solution for depots and maintenance facilities seeking to optimize workflow and reduce operational costs.

Quality Assurance & Compliance

As a trusted supplier to China Railway Chengdu Bureau, Xi‘an Bureau, Guangzhou Bureau, and other railway bureaus, as well as CRRC Qingdao Sifang and CRRC Digital Technology, every unit of our tooling is manufactured under strict ISO 9001 quality management standards. The product has been granted a utility model patent (CN224493565U), reflecting its novel design and practical utility in the field.
