|20140231564||DEMOLITION APPARATUS - A demolition apparatus and an adapter frame of the demolition apparatus are disclosed. The adapter frame may be formed with coupling seats which engage pins on a jaw set to assemble the demolition apparatus. The openings of the coupling seats face different directions for quick and simple assembly of the demolition apparatus. A rotatable locking element may be provided on the adapter frame to lock a pin on the jaw set.||08-21-2014|
|20130327864||JAW ASSEMBLY FOR A DEMOLITION TOOL - A jaw assembly for a demolition tool is disclosed. The jaw assembly comprising at least one seating portion disposed on a second jaw. The seating portion having a slot; and at least one work module removably mounted in the at least one seating portion. The at least one first work module comprises a base; at least one tooth extending from the base; and a mounting element extending from the base in a direction opposite to the at least one tooth and engaging the seating portion. The work module may be replaced when worn out.||12-12-2013|
|20130199644||COUPLING ARRANGEMENT - A coupling arrangement for fluid coupling a worktool to a machine comprising at least one coupler assembly slideably mounted in a cavity for coupling a machine fluid circuit and a work tool fluid circuit, the coupler assembly partitioning the cavity to form a chamber; a diversion path connecting the machine fluid circuit to the chamber; and a check valve positioned in the diversion path for flow of fluid from the machine fluid circuit to the chamber to generate a force on the coupler assembly for maintaining the fluid coupling.||08-08-2013|
|20130181150||COUPLING ARRANGEMENT - A coupling arrangement for fluid coupling a work tool to a machine comprising at least one coupler assembly slideably mounted for coupling a machine fluid circuit and a work tool fluid circuit at a connect position; an actuation circuit arranged to actuate the at least one coupler assembly from a disconnect position to the connect position; and a sensor to detect presence of the work tool for activation of the actuation circuit.||07-18-2013|
|20130177377||COUPLING ARRANGEMENT - A coupling arrangement for fluid coupling a work tool to a machine comprising at least one coupler assembly slideably mounted for coupling a machine fluid circuit and a worktool fluid circuit; at least one actuator for retracting the at least one coupler assembly from a connect position to a disconnect position; and a sensor to detect the position of the at least one actuator for actuation of a locking device.||07-11-2013|
|20130177376||COUPLING ARRANGEMENT - A coupling arrangement for fluid coupling a work tool to a machine comprising a plurality of coupler assemblies slideably mounted in a plurality of corresponding cavities for coupling a machine fluid circuit and a work tool fluid circuit, the coupler assembles partitioning the cavities to form chambers; and a rail circuit connecting the chambers.||07-11-2013|
|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|
