摘要： A jacking machine includes a main body, a support leg, a ball screw assembly, a power device, a braking device, and a self-locking device. The self-locking device includes: a chainring surrounding and fixedly connected to the screw rod, a toothed claw corresponding to the chainring and rotatably connected to a side of the main body, a first elastic member providing force to the toothed claw, and an electric actuator. A control method thereof includes after receiving a jack-up command, controlling the braking device to leave a braking state, and controlling the toothed claw to switch to a disengaged state, controlling the power device to drive the support leg and the main body to move relatively, and after receiving a stop command, controlling the braking device to enter the braking state, and controlling the toothed claw to switch to an engaged state.

摘要： The present disclosure relates a device for lifting objects. The device comprises a pair of arms, a horizontal bar, a slide bar, and a housing. The pair of arms are configured to be in an open state to lift an object and in a closed state when the pair of arms are not being used. The device is configured to be elongated to a length for providing ease of loading and unloading of an object. The device further comprises a locking mechanism for providing stability during transit. The housing comprises a roller over a screw for providing easy displacement of the slide bar with respect to the housing.

摘要： A linear lifting device including a lifting column, a synchronous adjusting mechanism, a first motion element and a second motion element is provided. The lifting column has a fixed end and a movable end. The synchronous adjusting mechanism, disposed on the movable end, has a first force-bearing end and a second force-bearing end, which are respectively separated from the center of the synchronous adjusting mechanism by a rotating radius and remain at a synchronous state. The first and second elements respectively connect the first and second force-bearing ends for generating a first force to push the first force-bearing end to move in a first force direction and generating a second force to push the second force-bearing end to move in a second force direction, such that the movable end can move with respect to the fixed end in a resultant force direction of the first and second force directions.

摘要： A portable electronic vehicle jack is provided. The present invention provides a vehicle lifting device including a telescoping hydraulic cylinder disposed inside a portable housing, wherein a piston is extendable and retractable therefrom. The piston includes an engaging member configured to engage a vehicle and sustain the load. An electrically driven hydraulic pump is operably connected to the hydraulic cylinder and includes a reservoir having a hydraulic fluid therein. The hydraulic pump is configured to displace the hydraulic fluid into and out of an expandable chamber within the hydraulic cylinder. Displacement of the hydraulic fluid into the expandable chamber exerts an upward force onto the piston, which drives the piston upwards along a vertical axis. A remote control having one or more switches is provided for activating the electrical drive of the hydraulic pump and displacing the hydraulic fluid to either extend or retract the piston.
