A material handling bucket apparatus including a material handling bucket and method of use thereof. The material handling bucket includes a bucket back half and a bucket front half. The bucket back half is configured to engage a loader. The bucket back half includes a plurality of guide slots and a dozer scraping lip configured to engage a surface. The bucket front half is pivotally coupled to the bucket back half. The bucket front half includes a plurality of slide members receivable in the plurality of guide slots. The plurality of slide members are configured to slide within the plurality of guide slots to allow the bucket front half to move linearly and pivotally relative to the bucket back half.

A skid-steer implement allows for the rotation of a tool attachment relative to the body of the skid-steer by coupling an attaching element and a rotation attachment device with a shaft and force generating devices. The slim construction of the device allows for bucket rotation while limiting the tipping load change caused by the extension of the implement.

A swivelable adapter device used with skid steer loaders includes a mounting plate and a swiveling work tool plate for holding, rotating, and positioning skid steer attachments. Rotation about a longitudinal axis of skid steer arms is accomplished using a barrel within a barrel assembly allowing the work tool plate to be positioned from angles between horizontal and vertical. A mounting plate is attached to skid steer arms and is rigidly affixed to an inner barrel. An outer barrel with a notch plate and a work tool plate slides over a greased inner barrel. Swivel operation of the work tool plate is accomplished by hand, eliminating the need for hydraulic systems. Once positioned, the work tool plate is locked to a notch plate using a locking mechanism, such as a locking pin or locking latch. The device is reinforced with metal plates to handle torsion forces created by heavy loads.

A hoisting apparatus includes a rotation device with connectors for connecting pressure-medium lines to a rotation device, a boom, from which the pressure-medium lines are arranged to lead to the rotation device, and a pivoted joint for suspending the rotation device on the boom. The pivoted joint includes two consecutive pivots in a longitudinal direction of the rotation device. The rotational axes of the pivots are at right-angles to each other. The pressure-medium lines are routed between lugs of the pivot on a boom side of the pivoted joint, past the connectors of the rotation device in the longitudinal direction of the rotation device, to turn towards the connectors to form a hose loop and then routed to the connectors of the rotation device. The pressure-medium lines are arranged on both sides of the rotation device related to a plane defined in the longitudinal direction of the boom and the longitudinal direction of the rotation device.

A control system for an excavator, the excavator comprising a movable arm, a movable excavator thumb and a tiltrotator attached to the arm, the tiltrotator being arranged to hold an auxiliary tool which is rotatable and/or tiltable by means of the tiltrotator. The control system is arranged to control the tiltrotator to rotate and/or tilt the auxiliary tool between a plurality of first positions and at least one second position. The excavator thumb is movable between at least one rest position and a plurality of work positions. The auxiliary tool is arranged to cooperate with the excavator thumb when the auxiliary tool is positioned in any of the at least one second position and when the excavator thumb is positioned in any of the plurality of work positions. The control system comprises a first blocker arranged to block the movement of the excavator thumb when the auxiliary tool is positioned in any of the plurality of first positions.

A hydraulic rotational drive for rotating load-handling equipment relative to a crane arm includes a shaft, which has a first securing element for connecting the shaft to the load-handling equipment or the crane arm, a shaft bearing, which has second securing element for connecting the shaft bearing to the crane arm or the load-handling equipment, vanes arranged in the shaft which can be acted on by oil via an oil feed, and an oil discharge for the transmission of a torque to the shaft. The rotational drive also has a rotary encoder for the detection of the angular position of the shaft relative to the shaft bearing.

A hydraulic drive system includes a swing directional control valve 81 and a third boom directional control valve 82 that are connected to a third hydraulic pump 33. Furthermore, the hydraulic drive system includes: a second auxiliary directional control valve 84 that is connected to the third hydraulic pump 33, and is connectable with a second special hydraulic actuator 64 for driving special attachments; and a first selector valve 96 that is connected to the third hydraulic pump 33 upstream of the second auxiliary directional control valve 84, and is connectable with an additional hydraulic pump 97. The first selector valve 96 switches the hydraulic fluid source of the second special hydraulic actuator 64 connected to the second auxiliary directional control valve 84 at least between the third hydraulic pump 33 and the additional hydraulic pump 97. Operability for combined operation of a special attachment can be improved in the hydraulic drive system equipped in advance with an auxiliary directional control valve that is connectable with an additional hydraulic actuator for driving the special attachment.

Fully rotating rotary actuator of a multi-purpose machine in which an axle supports the frame of a felling head by a bearing mount, there being a rotary mechanism driven by a rotary motor between the axle and the frame, and in which the connection of the axle includes rotatable joints, the axle includes conduits for electrical cables and a processing fluid line, and in which an additive fluid line tube is arranged in the conduit in the axle and connected to its lower end is a rotatable connector, which is connected to a second tube fastened in the frame for the application of the additive fluid.

A construction machine capable of reducing a resistance that a bucket receives from the ground and improving smoothness of a construction surface includes a working device including a working device body and a bucket, first and second bucket actuators that rotationally move the bucket, and a control device. The control device controls the second bucket actuator to make the second bucket actuator periodically oscillate the bucket in a direction of a yaw motion during excavation work or ground leveling work.

A system for controlling movement of multiple links of an excavator can move a tool at the end of an excavator arm. The system includes a sensor data interface configured to receive sensor data for determining relative orientations of the multiple links with respect to each other, and a surface setting unit configured to access design data defining a reference surface. The system has a remapping unit configured to remap a user command for moving two links with respect to each other about a corresponding joint to a rotatory tool degree of freedom. The system then coordinates output signals, such that as a function of the remapped user command the tool is rotated within the associated rotatory tool degree of freedom, without the need that an operator coordinates underlying joint movements.
