A jack pad device adapted to transfer loads between an aircraft and a jack device for jacking the aircraft, and a method for jacking an aircraft are provided. In one non-limiting example, the jack pad device includes a jack pad body. A jack engagement portion extends from the jack pad body and is configured to engage the jack device. A first coupler is attached to the jack pad body and is configured to couple to the aircraft to hold the jack pad device to the aircraft.

A crank mechanism incorporates a ratchet driver post coupled with a conventional, manually operated crank handle. The post is configured, possibly relying upon biasing members, pins, or sleeves, to ensure the ratchet driver may be operated without unwanted rotation of the handle. A number of iterations provide for multiple positions of the handle itself so as to speed up the early stages of jack actuation and then allow for repositioning in the later stages to maximize the user's leverage. Further still, a disengagement driver gear can be employed, and the invention may incorporate any combination of these features to improve operation and extension/retraction of the jack.

Height-adjustable fixtures for buried tubulars and methods of adjusting the height-adjustable fixtures. The height-adjustable fixtures include a frame and a plurality of slot nuts. The frame has an upper frame surface, a lower frame surface, a flange that defines a plurality of slots, and a central opening that extends between the upper frame surface and the lower frame surface. The central opening is sized to provide access to a buried tubular conduit of the buried tubular. Each slot nut is shaped to be received within a corresponding slot. In some examples, each slot nut defines a lower nut surface, an upper nut surface, and a neck region positioned between the lower nut surface and the upper nut surface. In some examples, when each slot nut is received within the corresponding slot, the lower nut surface is recessed within the corresponding slot.

A door hanging apparatus includes a base for ground contact. A height adjustment bracket is located above the base and includes a lifting platform for supporting an underside of a door. A leadscrew assembly, including a leadscrew, interconnects the base and the height adjustment bracket. The leadscrew assembly operates to vary spacing between the base and the height adjustment bracket in response to rotation of the leadscrew.
