摘要:
An assembly and a method for lifting a module of a lithography system from its support and a lithography system including such device are provided. The assembly includes a body and a track. The track comprises a ramp. The body is provided with two wheels. The first wheel vertically may extend a distance h further from a central horizontal plane of the body than the second wheel. An axis of the first wheel may be positioned in the horizontal direction at a distance D from an axis of the second wheel. The track may include a first and a second ramp. The first ramp is positioned at a distance D from the second ramp in the horizontal direction and a distance h in the vertical direction. Insertion of the body between the module and the support causes the module to be lifted from the support.

A lifting column includes first and second lifting column components, one slidably receivable in the other, each having mutually facing guide surfaces. The first lifting column component has first and second openings in its guide surface, and first and second guide components mounted in these openings. Each of the guide components includes an attachment structure that projects into one of the first and second openings and a substantially planar guide section connected to the attachment structure that overlies a guide surface of the first lifting component and that is configured to abut on the guide surface of the second lifting column component. The first and second guide components are configured such that they are in contact with each other when the attachment structures are mounted the openings.

A portable and foldable lift can be attached to a surface such as a tailgate of a truck. The lift can be slid off the gate and used to lift heavy objects from the ground to the bed of the truck. The portable and foldable lift is returned in a folded position to the tailgate for easy storage. The portable and foldable lift can also be attached to a work bench, either on top or underneath, and can be folded up and stored out of the way.

A storage apparatus and system, especially for kitchens. The apparatus includes a stationary counter portion, a moveable island riser, a lift assembly, and a guide assembly including vertically mounted guide shafts that support guide bearings situated in a housing mounted to the moveable island riser. Electronic sensors protect against operation of the lift assembly when interfering objects are sensed, and then lift assembly operation is interrupted. The moveable island riser provides cabinet space or shelving and may be provided with electrical outlets for use with common kitchen appliances.

A system for collecting liquids from scrapped vehicles, suitable for completely collecting liquids remaining in a scrapped vehicle, such as fuel, engine oil, brake oil, transmission oil and the like. The system includes a floor having rails positioned in a longitudinal direction on which a bogie frame moves, a lift having posts and carriages for raising the bogie frame together with a scrapped vehicle loaded thereon, a first scaffold and a second scaffold, hydraulic cylinders installed at each corner of the second scaffold, thereby adjusting the height of the second scaffold and a control panel for controlling the operation of collection of liquids from a scrapped vehicle.

A utility cart unloading system that is both functional and necessary. The system includes lifting platform that fits inside dimension of a cart and is attached with two sheets of canvas on each side to two steel tubes which are than installed into a metal frame that fits onto the top rim of a cart. An electrical DC motor rotates the steel tubes clockwise and counterclockwise simultaneously by means of chain transmission in the same direction at the same time and at the same speed and is controlled by rocker switch. By winding the canvas around the steel tubes, the lifting platform travels up and the contents of the cart are lifted.
摘要:
A device for lifting and positioning a heavy object, comprising a base, a pair of arcuate arm moving rack gears, a pair of arms rotatively affixed to the arcuate rack gears, a pair of arm moving pinion gears fixed to an axle rotatively affixed to each arm and in mechanical engagement with one of the pair of arcuate arm moving rack gears adapted when rotated to move the pair of arms up and down, a foot device rotatively affixed to the pair of arms, a foot pinion gear fixed to an axle rotatively fixed to the pair of arms and fixedly attached to the foot to rotate the foot when the foot pinion gear is rotated, a foot control pinion gear fixedly attached to the base, an elongated member having a rack gear on both of its terminal portions, one of such rack gears in mechanical engagement with the foot pinion gear and the other elongated member rack gear in mechanical engagement with the foot control pinion gear so that when the arm moving pinion gears rotate they cause not only the arm to move up and down but also cause the rack gear of the elongated member in engagement with the foot to linearly move the elongated member rack gear in engagement with the foot control pinion gear and to thus rotate the foot pinion gear to maintain the foot stable and essentially horizontal as the pair of arms are moved from the horizontal to the vertical position and points in between.
摘要:
A truck with a sidemember (1) resting, by its ends, on two adjustable crossmembers (3) fitted with a plurality of rotatable wheels (4) and including two slides (8), each bearing a support (15,16). The height, the longitudinal position, and the angular orientation of support 15, 16 can be adjusted by various adjustment devices. Each slide (8) has a locking device (9) on the sidemember (1), including a screw adapted to engage a nut in a plate (10) located in the sidemember. Each support (15-16) has a screw-jack (13,14) rests on a pipe (11) interdependent with each slide (8).
摘要:
A car hoist comprising runways, a lift mechanism disengageably engageable with the runways and operable to lift and lower them through a range of elevations, props for temporarily propping the runways at selected elevations within the range, and a jack carried by each runway operable by the lift mechanism when the runways are propped to raise and lower the car relative to the runway.
摘要:
A mobile lift caddy is configured to remove a vehicle from a primary lift while the vehicle is elevated above the workplace floor and then transport the vehicle to another location. The mobile lift caddy is dimensioned to fit between vertical lift posts of the primary lift. A mobility drive arrangement moves the caddy under operator control to and from the workplace location. Caddy lift arms are configured to accept a portion of removable lift pad assemblies at the lift arms of the primary lift, to lift out the lift pad assembly with the vehicle supported on the lift pads.
