摘要： A lifting device having an axle and a pair of wheels attached to the axle, a support element secured to the axle, a vertical element secured to the axle at an angle relative to the support element, and a handle secured to the distal end of the vertical element. In some embodiments, a safety arm is rotatably connected to the support element and the safety arm is moved from a closed position to an extended position, and vice versa, by simply rotating a handle grip which actuates a lever thereby moving a release pin from an engaged position to a dis-engaged position. The release pin secures the safety arm in the closed and extended positions. In further embodiments, a tooth is rotatably connected to the distal end of the support element and the tooth is biased inwards towards the lifting device by at least one spring.

摘要： An airplane jack to lift a light airplane nose wheel off the ground by the nose wheel fork to allow maintenance. The jack uses a lever to manually pivot on rollers to lift the nose wheel fork by non-marring cradling supports. A sliding lever provides unencumbered wheel access and extra safety against any possible pivoting of the jack by repositioning the lever. The jack's width can be adjusted to work with a plurality of nose wheel forks and varied in size and material to operate with a plurality of airplanes.

摘要： An aircraft jack and system is provided. The present aircraft jack may use electric, as opposed to hydraulic power. A scale may be incorporated into the jack to determine the lift load of the aircraft jack and a leveling device may be used to properly level the aircraft when lifted. A system of multiple jacks may allow the multiple aircraft jacks to communicate with each other and to synchronize movement electronically and automatically. A worm gear may also reduce the occurrence of collapse.

摘要： Method and apparatus for improved height adjustment of wall partitions. According to the present disclosure, an extendable Foot Controlled Elevator Device is placed beneath a wall partition. A user may then apply downward force on a Vertical Height Control to adjust the vertical position of the wall partition. In some embodiments, the Foot Controlled Elevator Device has a compressible base, allowing it to fit into tight areas (e.g., between toilets in a restroom under construction). In other embodiments, one or more Foot Controlled Elevator Devices may be linked, allowing for better control over the wall divider and simultaneous or distinct control of the respective Foot Controlled Elevator Devices.

摘要： A loading and unloading device is disclosed that provides users with a convenient and hands-free way to move a dragster or other suitable vehicle in and out of a trailer. The loading and unloading device comprises a dolly, a winch, and a pulley system. The winch is secured to the dolly, and functions to secure a winch cable to a dragster and pull the dragster in toward the dolly. Furthermore, a pulley system is secured to the dolly for redirecting the winch cable from the winch. The dolly can also comprise an arm that is secured to either end of the dragster and that raises or lowers either end of the dragster. The dolly can also comprise wheels secured to front and rear axles of the dolly to allow for ease in transportation of the device.

摘要： The present disclosure is directed to device to lift, maneuver, hoist, and install an item such as a flat screen TV, cabinet, mirror, window, on the wall, such installation that would normally require more than one person. The present disclosure relates generally to a device that can lift large bulky heavy items in both vertical and horizontal directions for installing, mounting, and placing on the wall. This is accomplished by smooth and precise horizontal and vertical motion that is controlled by the operator. Manpower has been the common device of choice in many of these instances, and this invention will succeed in the cases that include handling bulky, large, cumbersome items or general items in congested or hard-to-reach places that would typically require more than one person to perform the lifting, installing, mounting, or moving.
