| 20090107015 | Lock Device of Work Machine - A lock device is improved in durability by operating the operation member of a boom lock device in a non-contact state to solve a problem in a conventional work machine because there is a problem that the operation member is worn at the lateral rotating part of a boom bracket. In the lock device | 04-30-2009 |
| 20090107014 | Push block for a scraping device - An earthmoving scraping device is disclosed. The scraping device includes a bowl-shaped frame having a front end, a back end, and opposing first and second side walls extending upwardly from a floor. The first side wall, the second side wall, and the floor define an interior of the frame for transporting material over a surface. A mechanism is configured for adjusting the frame to change the height of the frame relative to the surface. A push block is mounted adjacent the back end of the frame and includes a bumper. A linkage system pivotally connects the push block to the back end of the frame and is configured to maintain a consistent height of the push block from the surface when the mechanism adjusts the frame to change the height of the frame relative to the surface. | 04-30-2009 |
| 20140123524 | BACKHOE ASSEMBLY - A backhoe assembly for securement to a common road vehicle, such as a pickup truck. The backhoe assembly includes a horizontally extending rigid trailer hitch receiver insert for insertion and retention into the vehicle trailer hitch receiver and a rigid support column is provided having one end detachably secured to the vehicle rear bumper and the other end secured to the trailer hitch receiver insert. An articulatable backhoe arm is secured at its proximal end to the rigid support column for pivotal movement of the backhoe arm in vertical and horizontal directions. A drive is connected to the backhoe arm for articulating the backhoe arm whereby the work loads applied by the backhoe arm to the vehicle are equally born or supported by the vehicle trailer hitch receiver and the rear bumper. | 05-08-2014 |

| 20100257758 | ARRANGEMENT FOR SUSPENSION OF AN OPERATOR CAB ON A WORK MACHINE FRAME - An arrangement for suspension of an operator cab on a machine frame in order to permit controlled motion of the cab relative to the frame is provided. The arrangement includes at least one first suspension member disposed between an underside of the cab and the frame for supporting the cab on the frame. The arrangement further includes at least one second suspension member disposed between a rear side of the cab and a rigid support structure and wherein the second suspension member is arranged at an elevated position relative to the underside of the cab. The second suspension member is adapted to provide an increased rigidity against cab movements both in the longitudinal and lateral direction of the machine during operation of the work machine. | 10-14-2010 |
| 20110061271 | HYDRAULIC LOCKING MECHANISM FOR SECURING TOOTH CARRYING ADAPTERS TO LIPS OF EXCAVATING BUCKETS AND THE LIKE - A connection for firmly securing an adapter for detachably carrying a replaceable digging tooth at its front end to a lip of an excavating container of excavating equipment. The adapter has an upper leg and a lower leg located proximate respective upper and lower surfaces of the lip. The connection has substantially aligned openings in the legs and the lip, and engagement sections of the adapter legs traverse the opening in the lip proximate and forward of an aft end thereof. A pressure applying unit, such as a hydraulic actuator, is arranged inside the opening and generates a generally horizontally acting force which draws the adapter and the lip towards each other. A stress member, which can be a C-clamp, is operatively coupled to the hydraulic actuator and resiliently deforms relative to its relaxed shape when it is subjected to the horizontally acting force. A spacer, such as a wedge, is inserted between the hydraulic actuator and the openings while the horizontally acting force resiliently deforms the stress member. The wedge is shaped so that upon a reduction or cessation of the horizontally acting force the stress member, e.g. the C-clamp, remains in the resiliently deformed state in which it draws the adapter and the lip towards each other and keeps them immovably secured to each other until the wedge can be withdrawn following a repressurization of the hydraulic actuator. | 03-17-2011 |
| 20110088291 | DIG UNDER APPARATUS AND PROCESS - A soil removal apparatus in one embodiment has a motive power unit and an excavator joined to the motive power unit by a coupler, the excavator extending laterally of the motive power unit. The coupler includes a manipulator for manipulating the excavator to loosen and displace soil material in a path lateral to a path of movement of the motive power unit. The method relates to undercutting an object with a motive power unit, selectively halting and moving the motive power unit, and loosening and displacing soil lateral to the path of travel of the motive power unit. | 04-21-2011 |
| 20120055050 | Multi-Function Wheel Loader Linkage Control with Optimized Power Management - A hydraulic system and earth-moving vehicle employing the hydraulic system are disclosed. The hydraulic system may include a first hydraulic cylinder and a second hydraulic cylinder, first and second hydraulic pumps and control valves to modulate provision of hydraulic fluid and pressure from the first and second hydraulic pumps to the first and second hydraulic cylinders as appropriate for the task being performed. If the task is digging with the earth moving vehicle, the first and second cylinders may be associated with tilting and lifting, respectively, and the control valves may be oriented so as to make each pump dedicated to one of the cylinders, and if demand is not being met, to then diminish power to the drivetrain to allow the tilting and lifting to be performed. The combiner may or may not be open during this time. If the task is not digging, a combiner valve can be opened to allow for cross-flow between the pumps and the cylinders. | 03-08-2012 |
