摘要

Jenkinson Electrical Engineering, a specialist panel builder and system integrator, has chosen Eaton to supply automation products which form the basis of a new versatile train lifting system developed by Mechan. The new lifting system allows a virtually unlimited number of lifting jacks to be synchronised with an accuracy of better than 2mm, allowing even the longest trains to be conveniently and safely lifted for servicing. A key requirement for the jacking system is that the jacks needs to be accurately synchronised while the train is lowered and lifted, so that the risk of distorting the vehicle bodies is eliminated, and the weight of the train, which may be as much as several hundred tonnes, is evenly distributed between the jacks. Also, to ensure that the system is fully compatible with current and future train types, the individual jacks must be physically separate units so that they can be positioned as required to suit different types of train body.
