The invention relates to a lifting platform for lifting vehicles, with two base assembly halves (14) with in each case one lifting device (24) arranged on the base assembly half (14), which includes a load arm (25) and a guiding arm (27), which arms, by means of at least one drive, are pivotably transferable out of a starting position arranged on the floor into an operating position (32), and which comprises a carrier (31) in in each case one end region of the lifting device (24), which carrier is mounted pivotably to the load arm (25) via a pivot bolt (54) and is mounted pivotably to the guiding arm (27) via a bearing bolt (63), and each carrier (31) receives at least one support arm (34) arranged pivotably thereon, so that the support arms (34) opposite one another are pivotable in a working space (50) formed at least between the lifting devices (24), wherein an angle of inclination is adjustable between the at least one support arm (34) and the lifting device (24).

A refrigerator includes a lift that moves a container upward and downward. The refrigerator may include: a cabinet having a storage chamber provided therein and an opening; at least one door provided such that a front of the storage chamber provided in the cabinet is opened and closed; a cooling device cooling the storage chamber; the lift provided at a side of the storage chamber to fold downward and unfold upward so as to move the container upward and downward; and an anti-loosening device provided at a side of the lift and allowing the lift to rotate relative to a front end thereof when the lift is removed upward so as to maintain a folded state of the lift.

A vehicle lift comprising a movement system configured to be installed in a pit in the ground, a platform engaged with the movement system and movable entering to and exiting from the pit, at least one arm carried by the platform and configured for contacting a vehicle to be lifted. The arm is movable between an extended position and a retracted position. The lift comprises a stop movable relative to the platform between a grip position where it engages the arm and a release position where it disengages the arm. The lift comprises an actuator carried by the platform and active on the stop to move said stop between the grip position and the release position.

A motor vehicle receiver hitch adapter with associated wheeled scissor lift cargo cart and mounted payloads. The hitch adapter comprises a variable pitch control system for mounting a cargo cart and attached payload in which the scissor lift mechanism within the cart is also capable of compressive force to power a dynamic pitch control system. The cargo cart also incorporates a restraint system to prevent carrying vehicle damage, and a vibration dampening system to protect carried payloads.

The present invention discloses a multifunctional vehicle lifting, steering, moving and obstacle crossing device. The apparatus is composed of a rotating mechanism, a lifting mechanism, a running mechanism and a control mechanism, is mounted at a bottom of an automobile, can be conveniently folded at the bottom of the automobile when not used at ordinary times, and has characteristics of portability, flexibility, no space occupation and easy operation. The apparatus can realize functions of a vehicle, such as lifting, rotating, moving and the like, in a wired or wireless control manner, and effectively overcome defects that the vehicle cannot realize four-wheel off-ground, entire side movement and in-situ rotation or pass through a narrow road or stride across a wide ditch or cross a high and narrow obstacle, thereby completing relatively difficult tasks of the vehicle, such as parking, moving, turning-around and turning in a narrow space, crossing ditches etc.

The system can include: a container no, a set of sensors 120, and a controller 130. The system can optionally include a robot 140. However, the system 100 can additionally or alternatively include any other suitable set of components. The system functions to monitor and/or maintain a fullness level of a container. The system can additionally or alternatively function to enable robotic picking out of the container (e.g., in a pick-and-place setting). The system can additionally function to maintain candidate objects within reach of the robot's end effector to increase robot uptime while minimizing the extent of the robot's required motion (e.g., in the z-axis).

An apparatus for aligning tubes of a heat exchanger includes a generally planar body having an insertion end and an actuator end, a first driving member received by the body and extending between the insertion end and the actuator end, the first driving member being movable axially with respect to the body, and a first biasing member operatively connected to the first driving member. The first driving member is actuatable to move the first biasing member between a clearance position in which the first driving member lays generally flat within respect to the body, and an extended position in which the first biasing member extends generally perpendicular from the body.

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).

A lift assembly for a utility vehicle storage area includes a floor supported by a scissor mechanism, an actuator for raising the scissor mechanism and the floor from a neutral position to an elevated position, a plurality of rollers attached to the floor, guide members attached to the scissor mechanism and within which the plurality of rollers move, and a detent protruding into one of the guide members to resist rotation of at least one of the plurality of rollers and create a pivot point about which the floor rotates to a pivoted position. The floor may be rotated to the pivoted position from the neutral position, the elevated position, or any position between the neutral and elevated positions. In addition, the floor may be removed from the assembly by passing the first and second pairs of rollers through the cutouts in the guide members.
