Operation of rerailing with the SAMS system for ALSTOM tram



In motion, the horizontal plays ensure that the jacks remain straight, even in the most extreme positions. This unique design eliminates any risk of the equipment slipping, at all times.

The rerailing equipment can be fitted under the vehicle from one side, making rerailing possible under a tunnel or near a platform. That is a decisive advantage over other existing systems using a single rerailing beam. It is also possible to shift a vehicle in one operation placing one rerailing device on each bogie (in accordance to constructor’s recommendations).

Due to its design, SAMS’ systems are lighter than single beam systems. Two technicians can operate it safely. The two CRP rerailing devices are easy to handle thanks to retractable wheels. The 500 mm sliding stroke was designed to reduce the number of required operations.
