20080217874 | Active air suspension for mobile liquid tanks - Apparatus, systems and methods for the stabilization of a mobile liquid tank during transportation of a liquid. Sensors feed information regarding the status and position of a liquid retained therein to a control unit which calculates expected movement of the liquid, and controls a set of pneumatic valves to adjust airsprings of a pneumatic suspension as to minimize undesirable movement of the liquid. | 09-11-2008 |
20100237573 | Air suspension control apparatus - An air suspension control apparatus for a vehicle is disclosed. The apparatus includes a charge tank maintained at a first air pressure such that selective filling of the charge tank with compressed air is permitted. The arrangement is such that, in a first disposition of the tank air valve, the charge tank is maintained at a second air pressure which is less than the first air pressure. When the tank air valve is in a second disposition thereof, the charge tank is maintained at the first air pressure. In a third mode of operation of the air suspension control apparatus, the tank air valve is in the first disposition thereof and a ride height air valve is in the first setting thereof. The arrangement is such that the first pressure within the charge tank rapidly inflates the air spring from the third pressure to the second pressure so that driving of the vehicle is permitted. | 09-23-2010 |
20100276897 | AIRPLANE TRAILER - A trailer having a frame movable between a raised position, suitable for towing of the airplane on a roadway, and a lowered position, allowing the airplane wheels to be in contact with a common surface with the trailer wheels when the trailer is under the airplane. A hitch assembly, suitable for towing the trailer in a closed position with the frame in the raised position, is coupled to the front of the frame. The open position allows the airplane to be loaded/unloaded on land from the front of the frame when the frame is in the lowered position. The airplane may be loaded/unloaded from the rear of the frame when the airplane trailer is placed in water. Also, a method of loading the airplane onto the trailer from the rear in water and unloading the airplane from the front on land. | 11-04-2010 |
20100276898 | STABILIZED MOBILE UNIT OR WHEELCHAIR - The present invention relates to a mobile vehicle or wheelchair having the ability to provide stabilized transport to at least one individual on a variety of surfaces, slopes and/or terrains. The mobile unit or wheelchair of the invention may travel across smooth and very rough surfaces, slopes of varying or different angles and various outdoor terrains (including grassy, rocky, sandy, muddy and/or hilly terrains). In one aspect of the invention, the height of any part of the unit or the overall height of the device may be adjusted preferably to raise or lower the center of gravity. For example, the height of the device may be lowered to provide more stable transportation. In another aspect, the device may be adjusted to increase or decrease the size of the footprint (or any part of the footprint) of the device. For example, the footprint of the device may be enlarged to provide more stable transportation. Preferably, both the height of the device (or any part of the device) and the size of the footprint (or any part of the footprint) may be adjusted preferably to provide more stability. | 11-04-2010 |
20100314843 | CHARGING VEHICLE FOR AN AUTOMATIC ASSEMBLY MACHINE FOR PHOTOVOLTAIC MODULES - A ground vehicle for feeding photovoltaic modules to an automatic assembly machine is disclosed, wherein the automatic assembly machine is movable on previously installed PV modules and the PV modules that still need to be installed are fed to the automatic assembly machine above a supporting structure. The ground vehicle has six vertically movable rams arranged in spaced-apart relationship in pairs in the direction of travel, with the PV modules to be installed located above the rams. Timing of the vertical ram motion is controlled so that a retracted ram of a ram pair is always extended before the other ram of the ram pair is lowered. | 12-16-2010 |
20100327544 | Cylinder Cart - A cylinder cart system that incorporates a stabilizing platform for safely loading and offloading of gas/fluid cylinders from trucks and the like is disclosed. The cylinder cart system incorporates a stabilizing platform to which a tank retention mechanism is attached that permits a gas/fluid cylinder to be retrained and raised/lowered via the use of an integrated elevator mechanism that may be manually or power operated. In the raised position, the cylinder cart provides sufficient stability to permit safe offloading of a gas/fluid cylinder onto a pickup truck or the like by a single person. In the lowered position, the cylinder cart incorporates hand truck functionality to permit transport of the gas/fluid cylinder across rugged terrain. An optional integrated safety braking system may in some embodiments provide additional stabilization of the system when the cylinder cart is in the raised position. | 12-30-2010 |
20120187641 | CART WITH HEIGHT ADJUSTABLE TRAY - A cart includes a frame body, a tray, a driving mechanism, and a transmission mechanism. The frame body includes a top portion, a bottom portion including a number of castors, and a number of connecting bars between the top portion and the bottom portion, which cooperatively defines a receiving space. The tray is configured to support a workpiece and to be slidably received in the receiving space. The transmission mechanism is connected between the tray and the driving mechanism to transmit the power of the driving mechanism to the tray to drive the tray to move in the receiving space. | 07-26-2012 |
20140232074 | TRAILER AXLE SUSPENSION SYSTEM AND A METHOD OF CONTROL - A trailer axle suspension system and a method of control. The trailer axle suspension system may be deflated when the trailer is approaching the dock and proximity of the trailer to the dock is within a predetermined limit. | 08-21-2014 |
20140312581 | TORSION SLIDE SUSPENSION - A torsion slide suspension has a pair of polyethylene slides on each side of the suspension that is received in slide channels on a trailer frame. The torsion slide suspension has a rubber spring on top for bearing against the trailer frame and provides suspension to support the wheels of a ground level loading trailer. | 10-23-2014 |
20150298519 | ASSEMBLY TO ADJUST THE HEIGHT OF AN AXLE OF A VEHICLE - An assembly for adjusting the distance between a wheel axle of a vehicle and a surface of a road. The assembly comprises: an axle casing connected substantially parallel to at least one wheel axle and rotatably connected proximal to an underside of the vehicle. The assembly also includes at least one actuator arm fixed to and exact tending from the axle casing. The assembly further having at least one retraction mechanism connected in a fixed position in relation to the vehicle. The mechanism has at least one retractable linkage connected to the at least one actuator arm, which is adapted to be adjusted in length to rotate the actuator arm with respect to the vehicle. | 10-22-2015 |
