Vector Lifting  offers a compact and efficient drop table developed specifically to assist with the safe replacement of a wheel set-traction motor assembly from under a locomotive.           

The drop table is designed to improve safety and efficiency within maintenance depots to ensure faster turnaround on locomotive services.

Installed in a pit below rail level, the drop table consists of a trolley, lifting columns, lifting platform and traction motor positioner. When not in use, the drop table is positioned in the ‘Home’ position to ensure the rail through the depot is continuous and the area of the pit is enclosed.

In the ‘Home’ position, the drop table rails are aligned to the service track rails and also locked into the foundation. Locking tongues slide from under the lifting table into the pit wall support brackets to support the lifting table for safe passage of locomotives and rolling stock over the drop table.

A pair of rails is fixed to the base of the pit to allow the drop table to traverse along the pit. Once the wheelset and traction motor are disengaged from the locomotive, the carriage will lower the assembly and travel to the maintenance line to allow the wheelset traction motor to be removed or repaired.

The lifting platform provides a work area for personnel to access the wheel set. An elevated structure from the floor of the lifting platform supports the traction motor positioner located on the platform to support and tilt the traction motor. This action positions the traction motor for its release from or reconnection to the locomotive bogie.

The wheel set is removed from or installed under the locomotive through the combined efforts of the trolley, lifting columns and traction motor positioner.
