Abstract: Disclosed is a pit cover and method of installing the same. The pit cover includes a plate having a hole defining an area. A block having a threaded hole may be affixed to a bottom surface of the plate such that the threaded hole aligns with the area. A support is associated with the foundation and a groove is defined by one of the pit cover or the support. A protrusion is defined by the other one of the pit cover or the support. The groove narrows from a first width towards a second width. The first width is disposed relative to the second width such that insertion of the protrusion into the groove causes an end of the protrusion to pass the first width prior to passing the second width. The protrusion interacts with the groove to align the pit cover at a predetermined position relative to the foundation.

The lifting system includes one stationary lift; a number of moveable lifts; positioning means for defining a position of a wheel axle of the vehicle; distance measuring means for determining the distance of the vehicle to a reference point; and control means for determining the distance between two vehicle axles and steering the one or more moveable lifts to the correct position.

Abstract: Systems and methods for jacking an aircraft structure using beams coupled to seat tracks attached to a floor beam grid structure. Mechanical load distribution plates can have offset lift pin location to allow a certain percentage of the load to be applied to specific seat tracks. Different quantities of seat tracks can be utilized per requirements. Attachment rails that interface with the seat tracks use the same hardware that is used to fasten aircraft seats to the seat tracks. This helps handle the load and prevent damage to the seat tracks. The jacking apparatus also includes load swivels and a hanger link to prevent any side or twisting loads from being applied.

Abstract: A method and apparatus for replacing old, in-ground hydraulic elevator lift cylinders in which a portable tower is erected within the elevator hoistway and a shoring sleeve of larger diameter than the old cylinder is secured to a head plate slidably mounted for vertical movement on the tower and facing downwardly. After loosening the hoistway floor and subsoil surrounding the old cylinder, a drive mechanism such as a winch or hydraulic jack is actuated to lower the shoring sleeve into the ground to surround the old cylinder. The head plate is then attached to the old cylinder, and the drive mechanism is actuated to lift the head plate and cylinder upwardly until the cylinder is raised completely out of the ground. The old cylinder is discarded, and a new cylinder is attached to the head plate and lowered into the area surrounded by the shoring sleeve.

Abstract: A service area is provided with a service area floor having a service pit sunken therein. A service lift is then provided within the service pit, and the service lift includes a service platform which is adjustable between a lowermost height to an uppermost height substantially equal to the height of the service area floor. Service personnel situated on the service platform within the service pit may thus actuate the service platform to various heights within the pit to allow comfortable servicing of the underside of a vehicle without the need to crouch or resort to the use of stepladders. The service platform can also be lifted to its uppermost height to effectively close the service pit, thereby enhancing the safety of the service area. The service lift most preferably uses air springs to effect the actuation of the service platform.

Abstract: A method of retrofit includes the steps of removing the pre-existing superstructure of the lift system. A hole is then cut in the encasement securing the upper portion of the pre-existing casing. Thereafter, all hydraulic fluid is drained. Thereafter, the pre-existing gland flange is removed. The old plunger is also removed. After the same has been accomplished, there is then provided a high pressure low volume hydraulic cylinder and associated hydraulic line, all of which is positioned within the casing of the pre-existing system. The bottom of the high pressure hydraulic cylinder is mechanically locked to the base of the pre-existing outer casing. A new pump and hydraulic lines are then installed. A new plunger is then added to the new hydraulic cylinder and, with it, an appropriate bearing and guide mechanism which uses the pre-existing casing as an outer guide means for the new plunger.

Abstract: An in-ground mechanical vehicle lift apparatus including an outer cylinder and a support tube rigidly attached to the outer cylinder. A ram cylinder is located between the outer cylinder and support tube in telescoping relationship to the outer cylinder and the support tube. The drive motor is mounted to the ram cylinder and a drive screw is operably connected to the drive motor for engaging a nut rigidly attached to an upper end of the support tube. The drive screw is driven in rotation by the motor to cause the ram cylinder to move upwardly and downwardly relative to the outer cylinder, and a vehicle support portion is located on an upper end of the ram cylinder for engaging and supporting a vehicle. The lift apparatus is adapted to be installed as a replacement for an in-ground hydraulic lift system wherein the lift apparatus is of a compact design which will fit within an existing in-ground cylinder of the hydraulic system.

Abstract: The present invention provides a lift used for automobile maintenance, which has a novel link mechanism consisting of a smaller number of parts required to have significantly high precision, and is manufactured at a relatively low cost. The lift allows a mechanic to check and repair a lower portion of a vehicle in a standing attitude. The link mechanism of the invention has a smaller number of joints, thus effectively preventing excessive looseness of the lift even after long-term use. The lift of the invention includes a pair of base elements placed in a pair of pits, a pair of tables for supporting a lower body frame of a vehicle other than four wheels, and a pair of link mechanisms where a long arm crosses and is fixed to a short arm at a position in the middle of the long arm via a center shaft. Each short arm is integrally fixed at a first end thereof to a connection shaft, which is rotatably attached to one side of the base elements.
