摘要： A high-performance sports car having: a chassis; a bottom facing a ground on which the sports car moves; four wheels supported by the chassis; four suspensions, each of which connects a corresponding wheel to the chassis, has a variable geometry, and is equipped with at least one actuator device adapted to modify the geometry of the suspensions; and a body which covers the chassis and is equipped with four wheel arches, each of which surrounds a corresponding wheel at the top. The chassis is provided inferiorly with a plurality of support feet which are adapted to rest on the ground to support the weight of the sports car. The actuator devices are configured to lift, only when the sports car is parked, the wheels upwards with respect to the chassis changing the geometry of the suspensions up to rest on the ground the support feet i.e. until the wheels detach from the ground.

摘要： A method of retrofitting a trailer having a crank jack with a jack housing and a jack leg into a hydraulic jack includes removing mechanical components from within the jack housing, the mechanical components comprising gearing of the crank jack, placing a hydraulic cylinder within the jack housing, wherein the hydraulic cylinder comprises a main cylinder and a ram piston extending outwardly therefrom as the main cylinder is filled with pressurized fluid, securing the hydraulic cylinder by fastening a top portion of the hydraulic cylinder to the jack housing using a fastener inserted through a hole in a platform positioned within the jack housing, and further securing the hydraulic cylinder by fastening the ram piston to the jack leg using a bolt extending through a pre-existing hole in the jack leg.

摘要： A tractor trailer jacking assembly f includes a plurality of jacks that is each mounted on a bottom of a tractor trailer. Each of the jacks is positionable in an extended position to engage the ground to inhibit the tractor trailer from tipping. A control circuit is mounted on a semi tractor and the control circuit detects the speed of the semi tractor. A gyroscope unit is mounted on the semi tractor to detect a degree and a direction to which the semi tractor is tipping. The control circuit actuates the respective jacks into the deployed position on a corresponding side of the tractor trailer when the gyroscope unit detects the semi tractor has tipped beyond a pre-determined angle of tilt.

摘要： The independent hydraulic jack system uses four independent jacks strategically mounted on the four corners of the bottom of a vehicle. Each of the jacks is connected via hydraulic hoses to a central hydraulic pump, also mountable on the bottom of the vehicle. The hydraulic pump can raise or lower any of the four jacks without affecting the other three. This hydraulic pump is controlled by a user-operated remote control whereby the user can directly adjust the height of the four jacks. The control also has a locking feature whereby the jacks will not alter their height until the control is unlocked. As a safety precaution, the pump cannot be utilized unless the vehicle brakes are applied.

摘要： A semi-trailer landing gear assembly can include a set of legs actuable to raise and lower a semi-trailer. Each leg can include a foot abutting the ground and a support abutting the semi-trailer. A rotatable shaft couples to the set of legs where rotation of the rotatable shaft raises and lowers the legs. A crank can operably couple to the rotatable shaft to rotate the rotatable shaft. At least two air drivers operably couple to the crank to rotate the crank in an opposing manner such that at least one air driver is always offset from the direction of rotation to provide continuous torque.

摘要： An apparatus is mountable on a truck or trailer bed for lifting industrial or agricultural spools for transport. The apparatus includes a pair of vertically pivotable lifting members, each one of the pair of lifting members having a distal end. A pair of lifting pins are mounted to a distal end of a corresponding lifting member. A drive system is operably connected to the pair of vertically pivotable lifting members whereby the pair of lifting pins engage a hole of a spool and the spool is lifted with the vertically pivotable lifting members by a drive system.

摘要： This device is designed for any automobile to have a built in vehicle jack and wheel chuck to safely change a tire or tires without the need to use a manual jack as all car manufactures supply somewhere in there car. This Vehicle Self Lifting Device uses a Hydraulic Air Compressor which is mounted on four locations on the chassis of the vehicle for solid and stable lifting of the vehicle. This device can be used on one or more sides of the vehicle as required by the operator of the device. Once the device is needed the operator will have to place the vehicle in a parked position in order to begin vehicle lifting operation. By pressing switch inside the vehicle the hydraulic air compressor will begin to lift the vehicle on the required side front or back of the vehicle or all four locations. Once the vehicle lifting is desired a lock pin inserted through device for safety. Then a wheel chuck that is housed within the vehicle is pulled down from the chassis to the ground to prevent any additional movement of the vehicle. Once the vehicle task is completed a reverse procedure is required to have the device in unused position.
