Abstract: A rolling lift includes a tiltable and laterally shiftable load table. Tilt mechanisms at the mutual corners of a lift deck and the load table enable tilting of the load table. The apparatus caster units at corners of the cart frame and a handle stowable relative to a base frame of the lift.

Abstract: A compact telescoping lift arm assembly includes an outer arm section pivotally connected by a pivot member to a lift carriage vertically slidable on a post and an inner arm section telescopically received within the outer arm section and movable in and out of the outer arm section. The inner arm section has a nesting slot formed at an inner end thereof to nest about the pivot member when the inner arm section is retracted into the outer arm section.

Abstract: A telescoping lift arm for a two-post vehicle lift has pivot structure radially offset from a longitudinal axis of the arm. An outer arm section is open at a distal end to enable an inner arm section to be retracted therethrough. A pair of the arms are bilaterally symmetrical and configured to be removable from lift carriages to enable lateral swapping of the arms.

Abstract: A three-level vehicle lift. The lift includes a four-post configuration in which each post includes a pair of vertically extending, side-by-side channels. Two platforms are provided. Each includes a carriage configured to engage a respective one of the channels in each post and a hydraulic actuator and lifting cable system disposed within the platform for lifting the platform. An actuation system having a single hydraulic pump is provided with a valve for selectively supplying hydraulic power to either an upper- or a lower-platform hydraulic circuit. The simplified lift and actuation system configuration reduces manufacturing, shipping, installation, and materials costs and complexities.

Abstract: A mobile lift apparatus includes a mobile base frame with sets of height adjustable, triple caster units, frame mounted floor brakes, a load deck, scissor linkage engaged between the base frame and the load deck, and a load table movable on the load deck. An actuator is engaged with the scissor linkage to extend and retract the scissor linkage.

Abstract: A safety latch mechanism for a vehicle lift includes a pawl support member secured to a support post guiding a lift carriage having vertically positioned stop blocks. A pawl plate rests on the pawl support member and is urged toward engagement with the stop blocks to arrest downward movement of the lift carriage. A release lever selectively retracts the pawl plate to release the carriage for downward movement. A cable connects between a pair of the pawl plates on a system with a pair of the lift units.

Abstract: A parking lift for vehicles. The parking lift includes a platform on which a vehicle can be parked and lifted by a pair of scissor-lifts configured to raise and lower the platform to enable parking of a second vehicle beneath the platform. A deck of the platform is provided with a gradual slope throughout its length to enable vehicles with low ground clearance to travel onto the platform without contacting an underside of the vehicle with the deck. Each of the scissor-lifts includes short leg and a long leg that is longer than the short leg. Upon actuation between lowered and raised positions, the legs raise an entry end of the platform a greater vertical distance than an opposite terminal end. The platform is thus tilted upward to place a deck thereof in a substantially level or downwardly sloping orientation from the entry end toward the terminal end.

A deck of the platform is provided with a gradual slope throughout its length to enable vehicles with low ground clearance to travel onto the platform without contacting an underside of the vehicle with the deck. The scissor-lifts each include a leg with a recessed portion that increases a spacing between a door of a vehicle parked under the platform and the leg and thus a range of motion available to the door. A pad may be disposed on the leg in the recessed portion to protect the door against damage caused by contacting the leg.

Abstract: A jack assembly includes a base, a support platform, a pair of links connecting the base to the support platform and an actuator connected between the base and the support platform. The actuator is operable to move the support platform between lowered and raised positions. The actuator may be coupled to a power assist cylinder which utilizes pressurized compressible fluid to assist in lowering the support platform. A safety lock system includes a lock bar pivotally connected to the support platform and one or more pockets on the base positioned to receive a free end of the lock bar to retain the support platform in a selected raised position. A preferred support platform includes trays which receive contact blocks selected from a set of varied contact blocks. A portable automobile lift comprises a pair of the jack assemblies in combination with a portable power unit.
