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.

A lifting device with a head cavity in the lifting member shaped to accept a removable lifting head. The head cavity in the lifting devicee.g., the piston of a bottle jackmay 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.

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.

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 machine leveling pedestal incorporating a cylinder and piston defining an interior space, having a helically threaded outer surface, and having an upwardly facing land; a hydraulic fluid port opening the interior expansion space; a nut having a downwardly facing land and gear teeth, the nut being threadedly mounted over the helically threaded outer surface; a drive gear connected to the cylinder and piston for vertically slidably engaging the drive gear with the gear teeth, and, upon alternate rotations of the drive gear, rotating the nut about the cylinder and piston so that the nut vertically moves between a mechanical support position and a hydraulic support position, the upwardly and downwardly facing lands contacting each other upon movement to the mechanical support position, and the downwardly facing land displacing upwardly upon movement toward the hydraulic support position; and a motor connected to the drive gear.

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.
