Outline

The light railcar maintenance garage for Calgary Transit was searching for a method to raise transit cars for maintenance and repairs. Calgary Transit wanted to ensure that the equipment would provide a non-straining ergonomic level for their maintenance personnel. The solution:  a local machine builder designed and built eight “jacks” incorporating a Joyce/Dayton screw jack in each. In order to elevate a railcar,  four jacks are positioned on each side of the railcar and raised separately to the desired height, allowing maintenance personnel to perform work underneath and on each side.

Each piece of equipment features a Joyce® mechanical screw jack (model WJ810-96-KFTN). The screw jack is covered with a bellow to protect the screw from dust and debris, as well as eliminating any pinch points. By using Joyce screw jacks, there is zero backlash when the car is in the raised position and require minimum maintenance. These jacks have been in service for well over 20 years.
