Mackworth TX Advanced Ceiling Track Lift
About Lesson

This section will cover the details of how to remove, refit and replace all serviceable parts of the ceiling lift. Ensure to read and understand each step thoroughly before removing any component from the ceiling lift.

Ideally, the ceiling lift should be removed from the track and placed on a work bench before any dismantling. But servicing can be done with the ceiling lift remaining within the track system. (Depending on the service required).

Unless stated otherwise, all images refer to a Mackworth TX600 Advanced with a standard wheel assembly (Track Type 1). Where necessary, additional images for alternative track and ceiling lift types have been included.

Before carrying out any dismantling of the ceiling lift, the power should be turned off using the red pull cord.
