Cradle assemblies for supporting a door of an aircraft to facilitate servicing the door, and arrangements and methods for the same are provided. In one example, a cradle assembly includes a base and a cradle support subassembly pivotably coupled to the base. The cradle support subassembly is configured to support an outer section of the door.

A pallet sled includes an upper frame including spaced-apart arms adapted to receive feet of a pallet therebetween. A lower frame supports the upper frame. A plurality of pivotable arms connect the lower frame to the upper frame. A handle is pivotably connected to the lower frame and the upper frame, such that pivoting the handle selectively raises and lowers the upper frame relative to the lower frame.

A transport cart for transporting a ballast block upon a ground surface by a user. The ballast block has a front, rear, top, bottom, and has a plurality of fastening openings on the top. The transport cart has a main frame having a pair of parallel side members, a wheel assembly, a pair of overhead frames attached between the side members, and a cross member attaching the overhead frames. A lifting mechanism is attached to the cross member and includes a lifting arm extending parallel to the side members, and a pair of engagement plates attached to the lifting arm. The engagement plates fasten to the fastening openings on the top of the ballast block. The lifting arm is raised by rotating a handle to raise the block above the ground surface, whereupon the ballast block may be moved along the ground surface using the wheel assembly.

A vehicle door removal and storage dolly using a height controllable upper frame with side extending door support platforms that allows the vehicle doors to be positioned both vertically and horizontally for installation and removal from a vehicle. The extending door platforms are planarly aligned for a compacted position and include padded vertical door supports for supporting the vehicle doors during storage periods.

A method to maneuver a load is disclosed, and includes providing a set of uprights, including spacing a set of front legs laterally apart from one another, to extend in a generally vertical direction, and spacing a set of rear legs laterally apart from one another and longitudinally from the set of front legs, to extend in a generally vertical direction. The method also includes coupling a set of front arms to the set of front legs in a generally vertically adjustable manner, coupling a set of rear arms to the set of rear legs in a generally vertically adjustable manner, providing a set of rollers to support the front and rear legs to facilitate rolling of the apparatus over the ground, suspending a load in a space between the arms, and adjustably moving the uprights in a direction toward one another to maneuver the load.

A free access floor structure to install a manufacturing apparatus such as a semiconductor manufacturing apparatus, in a short time, and a manufacturing apparatus and a carrier apparatus adapted for the floor structure. An embodiment of the manufacturing apparatus includes an apparatus-side connector which is provided, facing downward, to a bottom plate of a manufacturing apparatus. A floor structure of an embodiment includes a floor plate to be worked into a floor surface. The floor structure includes a floor-side connector which is provided, facing upward, to the floor plate so as to be connected with the apparatus-side connector according to a lowering operation of the manufacturing apparatus. An installation step (mounting step, piping/wiring step) of the manufacturing apparatus may thereby be performed in one step. As a result, the labor and the time required to install the manufacturing apparatus may be saved.

An apparatus to maneuver a load includes a set of uprights including a set of legs extending generally vertically upward and a set of arms extending from the legs in an adjustable manner. A set of rollers supports the legs to facilitate rolling of the apparatus over the ground. The load is suspendible within a space between the arms, and the uprights are adjustably movable in a direction toward one another to maneuver the load. The apparatus also may include a set of adjustable links extending between at least two uprights of the set of uprights, wherein the set of adjustable links aid in adjusting the uprights between angled and substantially upright positions. The apparatus may be a hoist for raising or lowering a hard top from a vehicle, wherein the apparatus straddles a vehicle hard top. A method is also disclosed and claimed.

A wear blade installation system for mounting a wear blade on a plow includes a wear blade that may be installed on a plow. A floor jack is provided and the floor jack may be manipulated. The floor jack has a lift arm and the lift arm has a lift plate. The lift plate is selectively raised and lowered. A lifting unit is coupled to the floor jack and the lifting unit is positioned on the lift plate. A gripping unit is movably coupled to the lifting unit. The gripping unit selectively engages the wear blade thereby facilitating the floor jack to lift the wear blade. In this way the wear blade is positioned to be installed on the plow.

A pallet jack includes a base and a pair of tines extending from the base. The pair of tines including a first tine and a second tine. A load wheel supports an outer end of each of the pair of tines. Each load wheel is configured to move toward and away from the respective tine to raise the tine off a floor on which the load wheel is supported. The first tine including a support surface configured to selectively be a lowermost surface of the tine to facilitate lateral displacement of the first tine.

A pallet lift includes a base and at least one platform for supporting an object thereon. The at least one platform extends forward of the base. A plurality of load wheels are below the at least one platform and configured to move toward and away from the platform to selectively lower and raise the platform. A plurality of load motors are each configured to drive one of the plurality of load wheels. At least one rear wheel is positioned below the base. At least one processor is programmed to control the plurality of load motors to provide differential steering to the pallet lift.
