Abstract
A transportable lift includes a base and an elevator connected to the base which is arranged to support and vertically lift a load relative to the base. Transport wheels are connected to the base and are vertically moveable relative to the base. A control mechanism is connected to a frame for the transport wheels to selectively disable transport when a load is on the elevator. The control mechanism includes a drive connected to the frame for the transport wheels which, in use, exerts a first transport enabling force on the frame. A counter drive is connected to the base and the drive which, in use, exerts a second force to compensate the first force and a weight of exclusively the lift.

A transportable lift comprising:
- a stand;
- a carriage connected to said stand, said carriage being arranged to support and vertically lift a load relative to said stand;
- transport elements connected to said stand, said transport elements being vertically moveable relative to said stand;
- an enable mechanism connected to said transport elements to selectively disable transport when a load on said carriage is present;
- said enable mechanism comprising a drive connected to said transport elements, said drive in use exerting a first transport enabling force on said transport elements and a counter drive connected to said stand and said drive, said counter drive in use exerting a second force sufficient to prevent contact of said transport elements with the around or floor therebeneath when the load is not present on said carriage.
