Chassis Dynamometer - Rolling Road

The CRT rolling road is a conventional twin drum eddy current chassis dynamometer, capable of testing front or rear wheel drive vehicles to at least 300hp. The dynamometer is installed in a pit in the CRT No.1 environmental test chamber and therefore the vehicle is at normal inclination and level.

The dyno can be used for energy consumption and temperature profiles for refrigerated trucks and vans with electric or traction engine driven refrigeration systems and as it is situated in an environmental chamber, a variety of conditions can be simulated, e.g. stop start with door openings for pharmaceuticals or home delivery etc.
