In one embodiment, a self-elevating platform lift for moving objects between a first level and a vertically-elevated second level is provided. The platform lift comprises: (A) a platform for supporting the objects; (B) a plurality of lift lines for connection at the second level and for moving the platform; and (C) a motor connected to move with the platform and wherein the motor operably is connected to the lift lines for moving the platform between the first and second levels while being supported by the lift lines. In another embodiment, a lift installation is provided for moving objects between a first level and a vertically-elevated second level comprising: (A) a platform for supporting the objects; (B) a plurality of lift lines fixed at one end to extend downward from the second level for moving the platform; and (C) a motor connected to move with the platform and wherein the motor operably is connected to the lift lines for use in moving the platform between the first and second levels while being supported by the lift lines.

The invention discloses a lift-press lock catch foldable crane and relates to loading machinery, namely, a crane. The crane comprises a wheel, a wheel lift-press lock catch, a horizontal positioning hole B, a foldable positioning hole A and a jack and is characterized in that: moving wheels at the lower end of a base can support the crane to move freely; a support leg is connected with the base through a pin shaft so as to form a revolving pair; the support leg and the base are provided with positioning holes; a bolt passes through the positioning holes on the support leg and the base so as to fix the support leg and the base in a U shape at a horizontal position or the support leg is rotated vertically around the pin shaft and fixed at a folding position with the base; and the wheel is mechanically connected with the wheel lift-press lock catch, so that the wheel is locked in a hoisting process. The crane has the advantages that: due to the adoption of the technical scheme, the novel support leg of the crane can be folded vertically, so that the crane has a greatly reduced floor area, convenient and flexible movement, convenient folding and high adaptability. The wheel is mechanically connected with the wheel lift-press lock catch, so that the wheel is locked in the hoisting process and does not slide when an object is hoisted and hoisting is performed safely.

A combination shipping container and vehicle is disclosed that may be handled and lifted in a similar fashion to a standard shipping container, and also may provide its own motive force for driving as a vehicle. The combination includes a vehicle frame that is generally the length and width of the standard shipping container. The frame provides a strong support framework for the combination. An engine is supported by the frame, and a suspension supports at least four wheels by the frame. A transmission mounted to the frame transfers rotational energy from the engine to at least two of the wheels through a transfer case and an axle. A driver's cab is fixed to and above the frame at a forward end thereof and includes driver controls for controlling the engine, steering and braking of at least two of the wheels, and other related motor vehicle functions. A container portion is fixed to and above the frame at a rear end thereof. The container portion is substantially hollow and is adapted for cargo to be transported therein. The length and width of the combination is approximately that of a standard shipping container, and the overall height of the combination is the height of the standard shipping container plus the height of the frame plus half of a height of the wheels. The frame may further include a license plate holder, a flap for each wheel, and any other required equipment to conform to vehicular laws in various jurisdictions.

A light fixture having a head, a yoke and a base, the yoke having handles for carrying the light fixture. Placing the handle at the upper part of the yoke is very efficient if the light fixture is to be carried. Access to these handles is possible directly in a flight case because there is sufficient space for getting access to the handles above the yoke. In terms of small light fixtures, an individual can easily carry the light fixture by these handles and safely lift the light fixture from a flight case. In the case of very large light fixtures, two individuals can lift the fixture from both sides of a flight case and can carry the light fixture by the handles. By placing the handles as high as possible in relation to the light fixture, the light fixture can be carried in a very stable manner.

A manual lifting apparatus for providing adjustable handles that allow a person to more effectively, efficiently, and safely lift objects. The present invention provides a webbing attached to two ergonomic handles that assists a user in lifting objects. The handles are adjustable to allow a user to adjust the height from which the user must lift the object thus allowing the user to effectively lift an object from the power zone to more effectively and safely lift objects.

A load handling mechanism for use with loaded tankers has two transverse attachment members associated with longitudinal beams supporting the tank structure. Cables and associated spreader bars are attached to the transverse attachment members to provide a single lift point loading means for the tanker allowing loaded tankers to be easily loaded and unloaded in to transport means such as ships.

The invention discloses a spray chamber hydraulic lifting device capable of achieving synchronous lifting. The spray chamber hydraulic lifting device comprises four stand columns arranged in a spray chamber. Gear bases are arranged on the four stand columns respectively, lifting racks are arranged inside the gear bases, lifting gears matched with the corresponding racks are arranged in the gear bases, the lifting racks are connected with lifting plates through bolts, pulleys matched with one sides of the lifting plates are arranged inside the gear bases, the gear bases are connected through a driving rod and two connecting shafts, the driving rod is arranged inside the spray chamber through a guiding base, the middle portion of the driving rod is connected with an air cylinder through a connecting plate, the two ends of the driving rod are connected with transmission gears and the connecting shafts respectively, and the lifting gears are arranged on the connecting shafts.

A wheel dolly for lifting and transporting a flat tire attached to an aircraft is comprised of a frame assembly having first and second laterally spaced frame members and a telescopic frame structure interposed between the laterally spaced frame members. A pair of tire scoops are pivotally coupled the frame assembly. An actuator is coupled between the tire scoops to pivot the tire scoops relative to the frame assembly in order to raise the tire scoops. A plurality of castors is coupled to the frame assembly to allow the frame assembly to roll in any direction.

Method for lifting a sinus membrane located between a sinus and a maxilla that involves the drilling of a hole of a given diameter in the maxilla reaching the sinus membrane, and includes introducing in the hole an ultrasonic tip having a distal part including a ring-shaped part of increasing cross-section and a distal end formed by a flat area extending generally perpendicular to the longitudinal axis of the distal part. The flat area of the distal part has a distal side facing away from the proximal part and is bordered by a rounding, the ring shaped part being larger than the body of the tip but closely corresponding to the diameter of the hole. The tip includes an internal irrigation channel emerging on the distal side of the flat area. While the tip is within the hole, the tip is advanced towards the membrane while ultrasound vibrations are fed to the tip and irrigation fluid is supplied to the internal irrigation channel. This creates a cavitation effect in the irrigation fluid between the tip and the membrane and a lifting force that gently detaches and elevates the sinus membrane without requiring a direct contact between the membrane and the distal part of the tip.
