ABSTRACT:
Installation apparatus for installing pre-assembled escalators having upper and lower ends in an operating position between upper and lower landings, including wheeled support apparatus for supporting and transporting an escalator. Scissors lift apparatus mounted on the wheeled support apparatus, and a pivotal escalator truss support and locater assembly mounted on the scissors lip apparatus, cooperate to provide both vertical and angular adjustment of the escalator, in order to permit the upper end to be aligned with and then supported by a support wall associated with the upper landing, and to permit its lower end to be subsequently lowered into a pit associated with the floor of the lower landing.
