The controller includes a swinging stopper unit to stop the swinging movement when the swing bracket in the pivotal movement reaches a center position at which the boom is orientated in a forward direction of the machine body.

The present invention provides a boom system 1 for breaking and manoeuvring oversize material. The boom system 1 is mounted or attached to a vehicle. The boom system 1 comprises a base 2, a column 5 protruding upwardly from the base 2 and a boom arm 3 moveably connectable to the upright column 5 at connection point 16. A moving arrangement 4 is provided to move all or part of the upright column 5 towards and away from the base 2 so that the connection 16 between the boom arm 3 and the upright column is moveable towards and away from the base 2. A mobile crusher comprising a boom system 1 for breaking and manoeuvring oversize material is also provided.

The present disclosure relates to a backhoe loader for efficient digging. The backhoe loader includes: a vehicle body, including a first vehicle body and a second vehicle body which are connected sequentially; a loading device, arranged on the first vehicle body; a control platform, arranged on the second vehicle body and configured to rotate by 360? relative to the second vehicle body; a cab, arranged on a first side of the control platform; and an excavating device, arranged on a second side of the control platform opposite to the first side, the excavating device being configured to rotate by 180? relative to the cab. The backhoe loader can realize functions of 360? excavating and bidirectional driving. When the excavating device works, the backhoe loader can be directly moved by folding stabilizers and without changing the position of a seat back and forth, so that the excavating efficiency is improved.

A working machine according to one aspect of the present invention, includes a support member, a turn member, a pin inserted to both of the support member and the turn member to turnably support the turn member on the support member, a flange fixed to the pin, a collar inserted to an insertion hole formed in the flange, a retainer bolt inserted to the collar and attached by being screwed to the turn member and the support member, a contact portion included in the flange, and a regulator included in the support member. The regulator contacts to the contact portion with a clearance kept between the collar and an inner circumference surface of the insertion hole, thereby regulating turning of the flange around the pin.

A pressure medium cylinder (1) for moving a toothed bar (3), comprising a toothed bar (3) on at least one side of which is formed a toothing (4). Inside the toothed bar (3), a cavity (6, 6a, 6b) is formed, extending to at least one end (7a, 7b) of the toothed bar. The pressure medium cylinder (1) further comprises a longitudinal structure (8, 8a, 8b), the longitudinal structure (8, 8a, 8b) and the toothed bar (3) being adapted movably in relation to each other, and the longitudinal structure (8, 8a, 8b) is adapted at least partly inside said cavity (6, 6a, 6b). The toothed bar (3) and longitudinal structure (8, 8a, 8b) are adapted in a sealed manner in relation to each other so that the toothed bar and the longitudinal structure are movable in relation to each other by the effect of a pressure medium.

A power bucket having a first and second bucket half pivotally secured together about a main axis by a pivot pin. The bucket halves are movable between an open and a closed position. A head is disposed above the bucket halves and at least one arm pivotally connects the head to one bucket half while at least one second arm is pivotally connected between the head and the other bucket half. A cylinder support is pivotally mounted to the pivot pin and one end of a hydraulic cylinder is attached to the pivot support. The other end of the cylinder is attached to the bucket. Upon actuation of the cylinders, the cylinders move the bucket halves so that a cutting edge of the bucket half moves in a substantially horizontal plane.

A floor support frame (8) is provided with a left side pilot valve (21). The left side pilot valve (21) is provided with a left side operating pedal (23) that is foot-operated. The left side operating pedal (23) is configured of a first foot board (26) that is mounted on the left pilot valve (21) to be rotatable in an upper-lower direction, a shaft (27) that is mounted in a rear portion of the first foot board (26), and a second foot board (28) that is mounted through the shaft (27) on the first foot board (26) to be rotatable in a horizontal direction. The second foot board (28) is rotatable between a storage position of overlapping the first foot board (26) and a use position of being rotated in the rear side of the first foot board (26). An operation regulating mechanism (29) is provided in the front side of the first foot board (26) to be engaged to the second foot board (28) when the second foot board (28) is rotated to the storage position to regulate a foot operation.

The present invention is provided with: a plate provided while one surface is directed toward the machine body structure of a working machine; a first support and a second support, which are raised from the one surface of the plate and which affix the plate to the machine body structure; a hydraulic hose which is routed on and along the one surface of the plate; and an electric component mounted on the one surface of the plate. The one surface of the plate has a hydraulic hose arrangement section where the hydraulic hose is arranged between the first support and the second support, and an electric component mounting section where the electric component is mounted so as to be adjacent to the hydraulic hose arrangement section.

A position detection device for detecting the position of a bucket of an excavator having a cab and one or more booms is disclosed. A boom is rotatably attached to the cab by a mounting structure that is rotatably attached to the cab by a shaft having a longitudinal axis extending basically vertically during normal use of the excavator. The bucket is rotatably mounted to a stick that is rotatably attached to the boom. The mounting structure is arranged and configured to allow the boom to be rotated with respect to the longitudinal axis of the shaft. The position detection device comprises one or more antennas arranged and configured to receive satellite signals. The position detection device comprises a sensor assembly configured to detect the angular position of the boom with respect to rotation about the longitudinal axis of the shaft.
