The inflatable jack consists of an air jack, extension hose, built-in car compressor and an air tank. Optionally, impact lug nut gun and tire gauge can be provided with the system. The air jack consists of two parts, flexible rubber bag, base and top plates which are made out of solid plastic to keep the jack intact and free from getting damaged. The air compressor and air tank are attached to the car and it draws power from the car battery itself. The air jack is able to withstand the weight of the car and it does not move from its location due to the solid plastic plate with a top rubber surface. There will be a button on the dashboard which upon pressing will turn on the compressor, which in turn fills up the air tank and releases the air into the jack. The air drain valve available on the air jack will let it deflate flat and it can then be placed in the trunk.

A pneumatic jack includes at least a base platform and a top platform. The base platform is configured to be supported by a plurality of pneumatic jets. The pneumatic jets are configured to raise and lower the base platform and endow the apparatus with the ability to hover. An air bladder, with internal baffling, is positioned between a middle platform and the top platform. As the air bladder is inflated, the top platform rises relative to the other platforms.

A lifting device, configured to expand in a first direction between a deflated configuration and an inflated configuration upon being filled with compressed gas, may have a continuous surface including a bottom surface, a lower and upper intermediate surfaces and a top surface. A bottom plate may be coupled to at least part of bottom surface and a top plate may be coupled to at least part of the top surface. The continuous surface may include a plurality of surface undulations that provide a low height profile when in the deflated configuration and a higher height profile when in the inflated configuration. The plurality of surface undulations may vary between a first and second height when in the deflated configuration, but in the inflated configuration the variance between the relative heights of any remaining undulations is relatively smaller.

A compact air compressor and vehicle jack comprises a case, an air bladder, and an air compressor. The case comprises a durable two-piece construction further comprising a plurality of latches and a carrying handle. The air bladder comprises a durable inflatable vessel located internally within the case. The bladder is capable of withstanding the weight of a car. An internal electric air compressor inflates the air bladder. Power to the air compressor is provided via a cigarette lighter adapter. In use, a user would undo the latches, place the case beneath the vehicle, supply power to the air compressor using an external switch, and inflate the bladder until the vehicle achieves a desired height.

The invention relates to a lifting apparatus (16) for an aircraft (1), comprising: at least one cushion (19) which can be blown up and has at least two chambers (20, 21); at least one compressor; and at least one pressure control device, wherein each of the chambers is connected to the compressor (7) via the pressure control device by means of a hose (9), wherein the lifting apparatus comprises a pressure-sensitive device (23) having at least two pressure sensors (25), and the pressure-sensitive device is arranged between the uppermost chamber of the cushion and that region of the aircraft to be lifted.
摘要:
An elevated platform is provided. The elevated platform includes a platform, a central support structure, and an inflatable bladder structure. The inflatable bladder structure is coupled to and partially encases the central support structure. The inflatable bladder structure is also coupled to the platform so that the platform is moved in a first direction as the inflatable bladder structure is inflated and the platform is moved in a second direction opposite the first direction as the inflatable bladder structure is deflated.

A material mover includes substantially rectangular top and bottom sheets connected to perimeter sidewalls defining at least one chamber. The bottom sheet is perforated with orifices at least in a central portion and has a greater width than that of the top sheet at least in middle and lower regions of the top and bottom sheets. A plurality of partition members connect at least portions of the top and bottom sheets to one another within the chamber, extend parallel to lateral edges of the top and bottom sheets, and are spaced from the perimeter sidewalls. A fluid weir is defined along an outer periphery of the bottom sheet to provide a fluid film reservoir at least under the central portion of the bottom sheet including the orifices. Fluid in the fluid reservoir is substantially contained by the fluid weir.

A control apparatus for carrying a heavy object is composed of a base which is connected with an elastic assembly that can move upward and downward, and the elastic assembly which is provided with an upper plate for loading the heavy object. By an upward displacement of the elastic assembly, the upper plate can push up the heavy object, and by a downward displacement of the elastic assembly, the upper plate of the elastic assembly can be escaped from the heavy object, and the heavy object can be escaped from the elastic assembly and the base, such that during a process of moving or transporting the heavy object, the heavy object can be quickly, conveniently, and safely escaped from or slid into the base, and in the mean time, a displacement of a weight-lifting vehicle or a crane can be eliminated upon being loaded with the heavy object.
摘要:
Load handling apparatus such as a lifting device has a movable platform on to which goods can be loaded that is movable relative to a base by at least one inflatable bag. The bag defines an internal inflation chamber and is disposed between the platform and the base such that upon inflation of the bag the platform is raised relative to the base. The bag is configured such that the inflation chamber is in the form an endless loop, or alternative has ends with seams that are configured to be loaded in shear when the bag is inflated. The bag is folded so as to define a plurality of superposed bag portions such that the chamber is divided into a plurality of interconnected and stacked sub-chambers. The device is simple, compact and stable. The bag has improved lifting capacity and is less prone to leakage.
