20090152025 | HYDRAULIC SYSTEM FOR LEVELING APPARATUS IN EXCAVATOR AND FORESTRY EQUIPMENT - A hydraulic system for a leveling apparatus in excavator and forestry equipment is provided, whereby an upper frame of the equipment is kept in a horizontal state even if a lower frame of the equipment is on an inclined ground against a horizontal surface H. The hydraulic system a pair of first and second actuators and a pair of third and fourth actuators for rocking the lower part of the upper frame, first leveling control valves for simultaneously controlling extension and contraction of the first and second actuators, second leveling control valves for simultaneously controlling extension and contraction of the third and fourth actuators a reducing valve for discharging a reducing pilot signal pressure, and flow control valves for discharging the pilot signal pressure for the spool shifting of the first and second leveling control valves when a control signal is applied from a preset leveling controller. | 06-18-2009 |
20100320010 | VEHICLE WITH LEVEL-ADJUSTING ARRANGEMENT - By means of the proposed invention, an extremely simple arrangement is achieved for obtaining level-adjusting movements in a vehicle ( | 12-23-2010 |
20120085588 | SUSPENSION SYSTEMS FOR A VEHICLE - A utility vehicle is disclosed. The utility vehicle may include storage areas under the dash. The utility vehicle may include suspension systems for utility vehicles having shocks with both a fluidic stiffness adjustment and a mechanical stiffness adjustment. The utility vehicle may include an electrical power steering. | 04-12-2012 |
20120318588 | Linkage Lift Mechanism for Off-Road Vehicle - A self-propelled implement may include a suspension arrangement with a suspension spring, an elevation toggling linkage, and a wheel. The suspension spring may support a main frame of the self-propelled implement at a sprung end. The elevation toggling linkage may be mounted at an unsprung end of the suspension spring. The elevation toggling linkage may be used to configure the self-propelled implement at a raised elevation or a lowered elevation. | 12-20-2012 |
20130168165 | MASS TRANSIT VEHICLE - A mass transit vehicle includes one or a combination of the following: floor portions that are angled for creating an incline of a floor of the buss; a door or entranceway that is angle relative to a fore-aft axis of the vehicle; and/or an entranceway that opens a relatively low height relative to the ground. | 07-04-2013 |
20150060162 | STANDING WHEELCHAIR - A standing wheelchair device includes a wheeled base for enabling the device to move on a supporting surface. A harness assembly includes a plurality of braces for attaching to parts of a body of a user of the device, at least some adjacent braces of being connected by joints. A lifting unit mounted on the base, supports a hip joint of the harness assembly, and is configured to raise or lower the hip joint. When the user is attached to the harness assembly and is in a sitting position, raising a height of the hip joint causes the user to assume a standing position. When the when the user is attached to the harness assembly and is in a standing position, lowering the hip joint causes the user to assume a sitting or reclining position. | 03-05-2015 |
20160375845 | WORKING MACHINE - A working machine includes a travel device, a motive power transmission device configured to transmit a motive power to the travel device, a transmission case configured to house the motive power transmission device, and a hydraulic operation fluid tank disposed on an upper surface of the transmission case. | 12-29-2016 |
