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.
