A lifting platform, includes a movable support frame composed of a first and a second frames being cross pivotally and slidably connect between a bearing platform and a base, at least a positioning connecting rod set between the movable support frame and a portion close to the middle of the bearing platform or the base, and a damping extension element combine with an adjustment element and mounted on the movable support frame between the bearing platform and the base; the damping extension element controlled with extension or locking for adjusting the cross angle of the movable support frame, the adjustment element is provided to adjust the position of the damping extension element to form different supporting force to balance difference of bearing weight of the bearing platform, to achieve the effect of reducing the force required to operate the bearing platform for lifting.

A scissor-lift platform comprises a scissor mechanism (1) and scissor elements (3) that are connected to form scissor element pairs by central bearings (2). At least one scissor element (3) of a scissor element pair has a bearing receiving element (4) that is removably connected to the scissor element (3) in order to receive the central bearing (2).

An apparatus for lifting vehicles includes a runway, a base, an actuation assembly, a first armature assembly, a second armature assembly, and a third armature assembly. The runway is designed to vertically lift a vehicle from a lowered position to a raised position. The runway is connected to the third armature assembly. In turn, the third armature assembly is connected to the actuation assembly, which is pivotally fixed to the base. The first and second armature assemblies also connect the base with the third armature assembly. The actuation assembly is configured to lift the third armature assembly, which is guided by both the first armature assembly and second armature assembly. In response to the actuation assembly, the third armature assembly then forces the runway from the lowered position to the raised position, thereby lifting the vehicle.

An oil pressure mobile device for a wood working machine is provided in a wood working machine, including a power mechanism and a lifting mechanism. The power mechanism is provided with an oil hydraulic cylinder having its inner wall annularly mounted with a piston fixed with a telescopic rod. The lifting mechanism is disposed with two wheel pressing plates at the underside of the wood working machine. The two wheel pressing plates are jointly provided with a connecting link connected with the telescopic rod, and respectively installed with a moving wheel. Thus, the telescopic rod is driven by the power mechanism to extend or retract and actuate the wheel pressing plates to produce angular variation to make the moving wheels stretch out of the housing of the wood working machine for facilitating shifting of the wood working machine with less labor.

A robotic under surface loader includes a mobility platform, a parallel manipulator, and a cradle. The mobility platform enables the robotic under surface loader to be moved into place beneath a downwardly facing surface to which a payload is to be attached. The parallel manipulator, which is carried by the mobility platform, carries the cradle, which may in turn carry a payload. The parallel manipulator may position the cradle in six degrees-of-freedom and, thus, precisely position a payload carried by the cradle in a location and an orientation that will facilitate its interaction with (e.g., attachment to, etc.) the downwardly facing surface. Methods for attaching objects, including large, heaving objects, to downwardly facing surfaces are also disclosed.

A scissor lift includes a base, a platform, a plurality of pivotally connected scissor links, a support column, and a locking actuator. The platform has a fixed horizontal orientation and being movable between a first elevation and a second elevation. The scissor links are arranged in a crisscross pattern and operatively connecting the base and the platform. The lift actuator is pivotally attached to at least one of the scissor links to selectively raise and lower the platform along a lift path. The support column extends alongside the lift path and positioned adjacent to the platform. The locking actuator is fixed to an underside of the platform and includes a piston member extendable toward the support column to operatively connect the platform with the support column when the platform is raised at the second elevation so that the platform is supported by the support column in the fixed horizontal orientation.

The invention relates to an in-ground lifting system and corresponding method for lifting a vehicle. The lifting system includes one or more lifts including at least one moveable lift; a support structure for mounting the one or more lifts in a pit; a moving drive configured for moving the one or more moveable lifts in the pit; a lifting drive configured for lifting one or more of the lifts for raising and/or lowering the vehicle; and a cover configured for covering the pit. The cover includes a number of cover elements. An individual cover element extends in a width direction of the pit. The cover elements are configured to move between a pit covering state and a lift moving state such that the one or more moveable lifts pass over and/or by the cover elements. The cover elements move when one of the one or more moveable lifts moving through the pit is approaching.
