A lift device includes a base including at least two rotatable wheels, a retractable lift assembly, and a coupler. The retractable lift assembly includes a first end coupled to the base and a second end that is movable relative to the base. The coupler is attached to the retractable lift assembly a distance from the first end and is configured to detachably couple the retractable lift assembly to an electro-mechanical device. The coupler includes a first flange, a second flange, a pair of diametrically opposed mounting studs, and a pin. Each one of the pair of mounting studs extends from a respective one of the first flange and the second flange. The pin extends through at least one of the first flange or the second flange below the pair of mounting studs.

A portable vehicle lift and methods of using the same are provided. The portable vehicle lift comprises a carriage, a head saddle, and a lift driver. The head saddle is movably connected to the carriage so that it is shiftable between a lowered position and a raised position. The lift driver supported on the carriage and configured to lift the head saddle.

A lift device includes a base, a retractable lift mechanism, a work platform, and a lift controller. The retractable lift mechanism is moveable between an extended position and a retracted position. The work platform is configured to support a load and is coupled to and supported by the retractable lift mechanism. The linear actuator is configured to selectively move the retractable lift mechanism between the extended position and the retracted position. The linear actuator has an electric motor and an electromagnetic brake. The lift controller is in communication with the linear actuator and is configured to determine the load supported by the work platform based on the actuator force applied to the work platform and the height of the work platform.

A conveyance system and the like capable of preferably conveying a conveyed object is provided. The conveyance system includes a conveyance robot, which is a conveyance apparatus, a drive controller, which is a controller, an information accepting unit, and a setting unit. The conveyance robot conveys the conveyed object. The drive controller controls an operation of the conveyance robot. The information accepting unit accepts an input from a user regarding information indicating stability of the conveyed object in a conveyance state. The setting unit sets an operation parameter of the conveyance apparatus in the drive controller based on the accepted information.

A motorized cart assembly for use in gardening and other outdoor chores includes a first motor that is operationally coupled to a rear axle of a rolling chassis. The first motor is configured to selectively rotate the rear axle to locomote the rolling chassis. A lift module that is coupled to the rolling chassis is configured to selectively raise and lower an item that is positioned upon an upper plate of the lift module. A handle, which is coupled to at least one of the rolling chassis and the upper plate, is configured to be grasped in at least one hand of a user to steer the rolling chassis.

A roller reversing and jacking device for handling equipment comprises a directional roller set, at least one set of reversing and jacking assemblies and a reversing roller set. The reversing and jacking assemblies comprises: a jacking slider restricted to and disposed on the frame through a slider guide post; a reversing and jacking eccentric shaft correspondingly disposed on the jacking slider, comprising an eccentric shaft segment, an eccentric roller and a transmission shaft segment; and a reversing and jacking drive motor connected to and/or disconnected from one end of the transmission shaft segment, and the reversing and jacking drive motor fixedly mounted on the frame.

A transport device for lifting an automated guided vehicle (AGV) from a floor surface includes a first frame including a plurality of first frame members and a plurality of wheels coupled to the plurality of first frame members, wherein the plurality of wheels are configured to contact the floor surface. The transport device also includes a second frame including a plurality of second frame members, wherein the second frame is configured to mechanically engage the AGV. The transport device further includes a lifting system configured to move the second frame and the AGV with respect to the first frame between a first position where the AGV contacts the floor surface and a second position where the AGV is spaced from the floor surface.

An integrated lift and dolly is presented which includes a lift mechanism for elevating a vehicle while simultaneously positioning wheels underneath to enable moving the vehicle as the vehicle's wheels are elevated off the ground. The lift assembly can further elevate the supporting frame to remove weight from the wheels of the lift assembly to allow long term storage without relying on the wheels to support the weight of the vehicle. This integrated lift and dolly lifts and supports the vehicle for storage and also facilitates easier service, inspection and cleaning.

An apparatus for lifting a vehicle top is disclosed. The apparatus may include a base frame including two or more legs and one or more support structures couplable to the one or more legs at a selected angle. The apparatus may include a body frame including a main support and a lifting arm bracket couplable to the main support. The apparatus may include a lifting arm including a lifting platform couplable to a lifting support and one or more stabilizing linkages couplable to the lifting arm bracket, the lifting arm, and the lifting support. The lifting platform may engage an underside of a vehicle top and maintain an orientation substantially parallel to a ground surface as the lifting arm rotates about an axis through the lifting arm bracket.

Cradle assemblies for supporting a door for uninstalling and/or installing the door to a fuselage of an aircraft, and arrangements and methods for the same are provided. In one example, a cradle assembly includes a first contoured board and a second contoured board that is spaced apart from the first contoured board. The first and second contoured boards are cooperatively configured to support outer sections of a first door. A third contoured board is configured to be selectively positioned adjacent to and extending higher than the first contoured board to support a first outer section of a second door that has a different outer shape than the first door. The third contoured board is contoured to substantially match the first outer section of the second door. The cradle assembly is configured to be positioned proximate to the fuselage.
