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.

An illustrative example elevator assembly includes a header beam and a first elevator cab supported by the header beam. A plurality of vertically oriented rods extend beneath the first elevator cab. A horizontally oriented mid-beam is coupled to a first one of the rods near a first end of the mid-beam and coupled to a second one of the rods near a second end of the mid-beam. A second elevator cab is situated beneath the first elevator cab and beneath the mid-beam. At least one linear actuator is supported at least partially on the mid-beam. The linear actuator selectively causes vertical movement of the second elevator cab relative to the rods.

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.

An industrial materials handling system including a base member having a loading end with a first senor that detects when a first carriage or second carriage is positioned in a loading/unloading position at the loading end, and an operator end with a second sensor that detects when the first or second carriage is positioned in the loading/unloading position, a controller coupled to the first sensor and second sensor, the first carriage coupled to the base member and a first drive mechanism controlled by the controller to move the first carriage, the loading end, and the operator end, the second carriage coupled to the base member and to a second drive mechanism configured to move the second carriage between the loading end and the operator end under the control of the controller, and a bypass mechanism to move the second carriage between the loading end and the operator end.

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.

A radial-scissor lift assembly for a table top comprising an upper support member, a lower support member, and at least three scissor assemblies coupled to the upper and lower support members. Each scissor assembly includes a table-scissor member rotatably supporting a table wheel adapted for contacting an unattached table. Each scissor assembly further includes a floor-scissor member rotatably supporting a floor wheel adapted for contacting a surface supporting the radial-scissor lift assembly. The radial-scissor lift assembly has an actuator assembly coupled to the lower support member and to the upper support member for moving the scissor assemblies. A method for lowering a table top comprising disposing a table top on at least three table rollers, and rolling the table rollers along the bottom on the table top and away from the center of the table top to cause the table top to be lowered.

A pallet jack includes a base and a pair of tines extending from the base. The pair of tines including a first tine and a second tine. A load wheel supports an outer end of each of the pair of tines. Each load wheel is configured to move toward and away from the respective tine to raise the tine off a floor on which the load wheel is supported. The first tine including a support surface configured to selectively be a lowermost surface of the tine to facilitate lateral displacement of the first tine.

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).

A lift device includes a base, a platform that is repositionable relative to the base between a fully raised position and a fully lowered position, and a scissor assembly coupling the base to the platform. The scissor assembly includes a scissor layer including a first scissor arm pivotally coupled to a second scissor arm. The first scissor arm is configured to rotate relative to the second scissor arm about a middle axis that extends laterally. A pulley is coupled to the first scissor arm. A tensile member is wrapped around the pulley and coupled to the second scissor arm. An actuator is configured to vary a working length of the tensile member such that the first scissor arm rotates relative to the second scissor arm to move the platform relative to the base.

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.
