A tire lifting assembly used to remove and replace a wheel and a tire on a vehicle is disclosed. The tire lifting assembly is configured to take the weight of the wheel and the tire when the service technician removes or replaces it thereby eliminating the need for manual efforts from a service technician. The assembly is rolled under the mounted wheel and tire and quickly adjusted to secure the wheel and tire by using a roller platform. A scissor jack mechanism is used to adjust the height of the roller platform which allows the rotation of the tire during the mounting procedure.

A vehicle lift includes a hydraulic cylinder having a component that rotates as the cylinder lengthens and shortens. A sensor measures the rotation or rotational position of the rotating component, and the sensor's output is used by a controller to control the vehicle lift. In some embodiments, the vehicle lift includes a scissor or parallelogram mechanism, while others are column lifts. In some embodiments, the controller uses the sensor's output to manage the limits of travel of the vehicle lift, and in others, the controller uses it to coordinate lift operations with other lifts.

A vehicle lift includes a vehicle support member, a cylinder, and a controller. A linear transducer—such as a string potentiometer—is (preferably removably) positioned inside the cylinder. The transducer detects the position of the cylinder and sends a corresponding signal to a controller that controls the height of the support member in response to the signal. The cylinder acts on the vehicle support member through a scissor mechanism, parallelogram linkage, or straight vertical hydraulic lifting.

A pit for containing a vehicle lifting apparatus is constructed from a plurality of precast concrete pieces and assembled in a trench. Conduit, plumbing, heating elements, and the like are cast into the pieces to facilitate safe construction/assembly of the pit. A lift apparatus is assembled or positioned in and at least partly attached to the pit. One or more mounting features are cast into and/or attached to the pit wall to help fix the lifting apparatus relative to the pit and/or to help fix the pit relative to a surrounding building.

An integrated lift and dolly is presented which includes a lift mechanism for elevating a vehicle while simultaneously positioning wheels underneath to enable moving the vehicle as the vehicle's wheels are elevated off the ground. The lift assembly can further elevate the supporting frame to remove weight from the wheels of the lift assembly to allow long term storage without relying on the wheels to support the weight of the vehicle. This integrated lift and dolly lifts and supports the vehicle for storage and also facilitates easier service, inspection and cleaning.

A lift for relocating a toolbox includes a base plate attached to a truck bed having a lifting mechanism mounted thereon. The lifting mechanism is attached to a rectangular support frame that is dimensioned and configured to cradle and grip the bottom wall of a given toolbox. When actuated, the lifting mechanism rotates within a ninety-degree range to move the toolbox from a lowered position, adjacent and parallel to the truck cab, to a raised position, adjacent and parallel to the bed sidewall.

A floor service jack includes a battery and a control panel provided at a distal end of a handle of the jack for electro-mechanically or hydraulically controlling a lift arm to raise and lower a vehicle for servicing without exposure to an undercarriage of the vehicle to replace the battery or to operate the control panel.

A lifting device with a head cavity in the lifting member shaped to accept a removable lifting head. The head cavity in the lifting device—e.g., the piston of a bottle jack—may be provided with threads, or may have the threads removed. A yoke fitted on the lifting head provides registration, horizontal restraint, or both against a lifted object, component, or surface to prevent sliding off the lifting head while in use. In a smooth-walled-shaft embodiment, a set of risers (spacers, adjusters, trims, or shims) serves to adjust an extension height of the shaft, elevating the lifting head with respect to the piston prior to beginning to lift the hydraulic piston.

In a lifting and transporting device for lifting a load (13) and for transporting the same transversely to the lifting direction (8), for use in the production of a screwed flange connection (35), in order to bring a tensioning tool (13) into a tensioning position in which it is in engagement with a screw bolt connection (18) to be pretensioned, or into a transport position in which it is out of engagement with a screw bolt connection and can be transported to the next screw bolt connection, wherein the flange (36a, 36b) extends horizontally, comprising a frame (2) for picking up and for lifting a load (13), a holding device (3) for holding the load, wherein the holding device is movable relative to the frame in the lifting direction (8), and comprising a hoisting device (4) for lifting and lowering the holding device (3) with the load (13) attached thereto, wherein the frame (2) is mounted on a first and a second support bearing (5, 6) and the first support bearing (5) is designed for abutment against the flange upper side (14), the frame (2) is designed to extend from the flange upper side (14) along the flange face (15) to below the flange underside (16), the second support bearing (6) is designed for abutment against the flange upper side (14) or against the flange face (15), the holding device (3) is equipped to hold the tensioning tool (13) below the flange underside (16) with the engaging means directed upwards, and the hoisting device (4) is equipped to lift the holding device (3) with the tensioning tool (13) attached thereto from a lowered transport position into a tensioning position.
