| 20080210485 | CONTROL SYSTEM FOR FRAME-STEERING OF A VEHICLE AND METHOD FOR CONTROLLING TWO STEERING CYLINDERS IN A FRAME-STEERED VEHICLE - A control system ( | 09-04-2008 |
| 20120118661 | STEERING SYSTEM OF INDUSTRIAL MACHINE AND METHOD OF CHANGING BODY-ARTICULATING ANGLE - A steering system, in a state where a first steering means is not operated, a third signal pressure output means outputs a third signal pressure in response to a second signal pressure fed to the third signal pressure output means, and feeding and discharging control means operates based in the third signal pressure, while in a state where the first steering means is operated, the third signal pressure output means stops outputting of the third signal pressure regardless of whether or not the second signal pressure is fed to the third signal pressure output means, and the feeding and discharging control means operates based on the first signal pressure. | 05-17-2012 |
| 20120138380 | Hydraulic Steering System For Forklift Trucks - A hydraulic steering actuator system for a forklift with front and rear sections includes a hydraulic steering motor. The forklift front section includes a mast mounting a pair of fork blades and a pair of wheels. The forklift rear section mounts a pair of drive wheels. The forklift front and rear sections are connected by an articulated connection with a vertical rotational axis. The steering actuator motor driveshaft extends generally along the vertical rotational axis. First and second actuator mounting brackets are connected to the forklift front and rear sections respectively. One of the mounting brackets includes upper and lower locking assemblies locking the hydraulic steering motor driveshaft whereby torque applied to the steering motor is transmitted to the articulated connection for turning the forklift front section relative to the forklift rear section. The range of motion is preferably 180°-205° for accommodating sideloading operations from relatively high storage shelves, e.g. in narrow-aisle warehouses. | 06-07-2012 |

| 20180022381 | POWER STEERING DEVICE | 01-25-2018 |
| 180420000 | Reciprocating power assist | 2 |
| 20110067944 | STRAIGHT MOTION ASSISTING DEVICE FOR A WORK MACHINE - A straight motion assisting device for a work machine is adapted for receiving an input indicative of a steering angle from a position of a moveable member and adapted for applying a restoring force for affecting the work machine towards a straight motion when the steering angle input indicates that the work machine deviates from the straight motion. The device includes a hydraulic system adapted to be effected by the displacement of the moveable member and adapted to apply the restoring force. | 03-24-2011 |
| 20150298730 | PRESSURIZED MEDIUM ASSEMBLY - A pressurized medium assembly includes a first working chamber and a second working chamber. The first and second working chambers are adapted to together produce a load. The pressurized medium assembly includes a first control arrangement adapted to provide a fluid communication between the first working chamber and a pressure line in an on/off manner. The pressurized medium assembly further includes a second control arrangement adapted to provide a fluid communication between the second working chamber and a pressure line. The second control arrangement is adapted to proportionally regulate the pressure in the second working chamber. | 10-22-2015 |
