  • Patent number: 7534095
    Abstract: An in-ground lift (10) is provided with a condensate scavenging system (30) that includes a pump (32) and a control (34) that is connected to the pump (32) and configured to selectively switch the pump (32) between a non-pumping state wherein the pump (32) is inactive and a pumping state wherein the pump (32) is expelling condensate from the base structure (12) of the lift (10). It is preferred that the control (34) be configured so that the pump (32) automatically switches between the non-pumping state and the pumping state in response to a predetermined change of state in the in-ground vehicle lift (10).

  • Patent number: 7219768
    Abstract: A lift with a multiple locking position safety leg includes a lift bed for engaging in objects to be lifted together with a fluid cylinder to be connected to the lift bed and extendable and retractable to move the lift bed between two extreme positions including a fully lowered position and a fully raised position. A latching mechanism is provided for holding the lift bed in any of a plurality of positions between the extreme positions and includes a plurality of vertically spaced latches operated by gravity to move to latching positions, one for each of the plurality of positions, and a single actuator for simultaneously moving and holding each of the latches against gravity from the latching positions to allow the lift bed to be moved to the fully lowered position. Also disclosed is a kit for retrofitting existing lifts with the safety leg.
