Under the condition that the entire subway train is not disassembled, it can jack up the wheel-set axle box and rotate thewheelsso as to fill the motor bearings oil dynamically anddetect the operating status of the axle box bearingssimultaneously.
Function: It has an axle box swing arm jacking device suitable for different heights of track bridges, and can drive thewheelset to detect the bearing status and dynamically fill the oil. It is convenient to move.
Innovation: It changes the previous mode that required the whole train to be jacked up and the bogie to be removed formaintenance. It can realize online driving detection of bearing status and dynamic filling of lubricating oil withoutdisassembling the vehicle and dropping the bogie, greatly improving the maintenance efficiency. The modular designmakes it possible to freely match with other testing equipment.

Train washing machines are used for the cleaning operations of the exterior surfaces of variouskindsoftrains (sides, side top arcs, top surfaces, and end faces).
The equipment can perform synchronous lifting operations of a whole or a half of a train set without decoupling, if can also lift one single carriage.
This system enables synchronized lifting of multiple coupled train sets without uncoupling, facilitating inspection,maintenance, repair, and replacement of mechanical, el...
