Dedicated to eddy current retarders — and to safer auxiliary braking
TLM is committed to making auxiliary braking safety widespread, and is a pioneer in electromagnetic induction retarders.
Company profile
TLM Auto Braking Systems (Shanghai) Co., Ltd. was founded in 2005. The braking performance and dependable quality of TLM retarders have earned wide praise from Chinese users, making them a preferred auxiliary-braking product for bus and truck operators at home and abroad.
To raise awareness of why commercial vehicles need a retarder, TLM has worked actively with the authorities and helped establish technical standards for vehicle auxiliary-braking safety.
TLM keeps improving eddy current retarder technology and its applications — refining product design, standardising production processes and raising quality to meet users’ need for safe driving.
Fitting a TLM eddy current retarder makes vehicle operation “safer, more economical and more reliable”.
We will continue to redouble our efforts to deliver better-performing retarders, giving our users a dependable guarantee of safe operation and better economic returns.

R&D, materials, process, quality
TLM has built deep experience in the design, manufacture, testing and application of eddy current retarders.
R&D
Idle power loss of retarders is typically around 2%; TLM eddy current retarders stay below 1%.
Materials
Rotors are precision-cast in chromium-, manganese- and vanadium-alloy steel for strength, rigidity and stability at high temperature with low remanence.
Process
CNC machining throughout. A more demanding process — chosen because it delivers strong braking and durable, reliable products.
Quality
Control components are approved to more than 2 million cycles (European standard: 1 million); insulation parts pass 80 thermal-fatigue cycles.
Creating value for customers
Customer needs first
Safer, more economical, more environmentally friendly products, and solid, honest, lasting relationships with customers.
Innovation as the path
Continuous innovation brings customers new products and value, and makes our own management more efficient.
