| 20110262212 | WORK TOOL COUPLING ARRANGEMENT - A coupling arrangement for coupling a work tool to a machine is disclosed. The coupling arrangement has a locking arrangement for locking the work tool to the machine. The coupling arrangement further has at least two fluid couplers arranged to be connected to each other for establishing a fluid passage between a main pressurized fluid circuit channel of a work tool and a main pressurized fluid circuit channel of a machine. The coupling arrangement further has a driving arrangement for driving at least one of the fluid couplers for connection to the other fluid coupler, the driving arrangement being separate from the main pressurized fluid circuit. | 10-27-2011 |
| 20110259441 | Extendable Pressurized Fluid Coupler - An extendable pressurized fluid coupler is disclosed. The extendable pressurized fluid coupler has a guiding portion having a central fluid channel. The extendable pressurized fluid coupler further has a piston having a central fluid channel, the guiding portion and the piston having a common central axis. The extendable pressurized fluid coupler also has a drive circuit for driving the piston. The piston is extendable with respect to the guiding portion. The guiding portion is arranged for guiding the piston along the central axis. The piston is arranged for connecting the pressurized fluid coupler to a corresponding coupler having a second fluid channel, so that a fluid passage for a main pressurized fluid circuit is established. | 10-27-2011 |
| 20100301622 | Gripping Member For A Work Tool - A gripping member for a work tool is provided such that in one embodiment, the gripping (or cutting) member includes a top and bottom surface, and a first gripping edge extending between the top and bottom surfaces, and a overbite block located proximate to the first gripping edge. | 12-02-2010 |
| 20100283275 | WORK TOOL FOR A MACHINE - The disclosure relates to a work tool for a machine and, more particularly, to such a work tool having an actuatable tool portion. According to one exemplary aspect of the disclosure there is provided a work tool for attachment to a machine, comprising a supporting tool portion. The actuatable tool portion is pivotally connected to the supporting tool portion via a hinge construction. The hinge construction includes a hinge drive having an outgoing, rotatable shaft. The rotatable shaft has a single outgoing end that is configured to carry the actuatable tool portion. By providing the work tool with a hinge construction that includes a hinge drive with an rotatable shaft that carries the actuatable tool portion on a single outgoing end a directly driven hinge construction is obtained that is both compact and reliable. The disclosure also relates to a hinge drive and to a method of operating a work tool for a machine. | 11-11-2010 |
