Abstract

A modular inground lift is supported by the lift bay floor. The lift includes self contained modules which have their own power units. A telescoping cylinder and locking leg allow the depth of the lift to be shallower than before. The use of VFD to control the motors allows monitoring of the loads, both during raising and lowering. The modular lift includes integral rebar to provide the structural connection with the lift bay floor.

Claims

1. An inground lift for use in a lift bay having a lift bay floor, said lift comprising:

a. at least one vertically moveable jack having a distal end; and

b. structure configured to interact with said lift bay floor to transfer substantially all load placed on said distal end of said jack to said lift bay floor.
