ABSTRACT:
A platform lift has support posts, and a platform that is coupled to the lift so as to be capable of being raised and lowered relative to the posts. A lifting mechanism moves the platform up and down relative to the posts. The platform has support structure and decking located on top of the support structure so as to provide a work area. An opening is provided in the support structure and the decking, which opening receives an engine, such as an aircraft engine. The platform provides a work area around the entire circumference of the engine, while the platform can be raised or lowered to provide access along the length of the engine. Filler plates can be provide so as to change the size of the opening to work on engines of different diameters.
