The invention relates to an axle lifting device comprising a load bearing support body; a base portion proximate a lower end of the support body, wherein an upwardly curved portion extends from the base portion, the upwardly curved portion including a plurality stepped formations for frictionally engaging the ground; and an axle seat proximate an upper end of the support body, to support or accommodate the axle of the vehicle or trailer, wherein the axle lifting device can rotate on the curved portion between a lowered position and a lifted position, wherein the axle seat extends substantially upright with respect to the ground with the base portion engaging the ground, for lifting the axle off the ground, with the stepped formations functionally and sequentially engaging the ground as the axle lifting device moves between the lowered and lifted positions

A robotic lifting and orienting system for an overspray-free paint system includes: a base coupled to wheels; and an automated carrier coupled to the base. The automated carrier includes: a fixture assembly configured to hold an object to be painted; one or more manipulators configured to move the fixture assembly relative to a paint robot; a propulsion system connected to the wheels and configured to move the robotic lifting and orienting system; and a control module configured to control the one or more manipulators and the propulsion system to control positioning and orienting of the object relative to at least one of the paint robot and an overspray-free paint applicator of the paint robot.

A multi-lift point elevator, which may be employed to lift a large, cumbersome object via independent lift points in order to elevate an object either levelly or at an angle and methods of use of same.

An apparatus for installing and removing glass panels and methods of using the apparatus are disclosed. The apparatus includes a base portion, a back support structure secured to the base portion, and a glass adjustment system moveably coupled to the back support structure. Methods for using the apparatus to install and remove glass panels from, for example, ice rink boards, are also disclosed.

A parking robot includes a lifting rail, a wheel clamp, and a lift motor. The wheel clamp is disposed on the lifting rail and is moveable from a first position to a second position along the lifting rail. The lift motor is operatively connected to the lifting rail and moves the wheel clamp from the first position to the second position.

The present invention relates to the field of engineering mechanics and more particularly, relates to an engineering work vehicle, and most particularly, relates to a vehicle with a low gravity center and aerial work platform. The vehicle includes a vehicle frame, a power system, a fuel tank, and a hydraulic tank all of which are mounted at a side of the frame. Correspondingly, the embodiment of the invention also provides an aerial work platform which provides better off-road performance and grade-ability, can work in complicated environment, and owns a longer horizontal reach and larger working range. Moreover, maintenance and repair cost is decreased, lifetime is extended, integrity is higher and appearance looks better.

The present disclosure provides embodiments of tilt hoists and lumber unstacking systems with a rotation table, a tier alignment system, or both. The rotation table may include a base and a tilt frame supported on the base. The tier alignment system may include an alignment beam and an actuator operable to raise and lower one end of the alignment beam relative to the opposite end to thereby adjust the lateral slope of the spill edge. Optionally, a control system may include distance sensors to detect tiers of lumber as they approach the spill edge and a computer system configured to determine a difference between the lateral slope of the tier and the lateral slope of the spill edge. The computer system may also be configured to automatically adjust the slope of the spill edge to match the slope of the tier before the tier is spilled over the spill edge.
