A skip pan for handling materials comprising a base of the skip pan for containing the materials. A portion of a contour thereof has walls and a remainder of the contour is a wall-less edge. A bridge holds the base and comprises, at the top, a connecting portion for connecting to an arm of a material handler. The connecting portion is rotatable along a vertical axis thereof to provide a spinning movement to the skip pan. The connecting portion is tiltable by the arm of the material handler. An actuator provides an adaptable inclination of the base of the skip pan with respect to the bridge to keep the base balanced when the connecting portion is tilted to avoid contents to slide by the wall-less edge during movement.

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.

The invention relates to a method for reproducing audio in a multi-channel sound system including two input signals (L and R), wherein output signals are generated for different sound perception levels. In order to develop said method in such a way that audio can be reproduced within a larger range of applications in a multi-channel sound system, according to the invention, only a lower sound perception level (7) and a higher sound perception level (6) are generated, and a maximum of six output signals are generated, a maximum of two output signals being allocated to the lower sound perception level (7) and a maximum of four output signals being allocated to the higher sound perception level (6).

The invention relates to a hydraulic rotator (11) for rotating a tool with respect to a crane arm, the hydraulic rotator comprising a first attachment piece (12) for connection to a crane arm and a second attachment piece (13) for connection to a tool; and a stator (14) and a rotor (15), the rotor (15) being rotatably arranged inside the stator (14) to rotate around an axial axis (A), wherein the rotor (15) comprises vanes (18) that are biased to extend radially outwards from said rotor (15), and wherein the stator (14) comprises an inner circumferential surface (25) to receive said vanes (18), which inner circumferential surface (25) comprises at least two chambers (19a) arranged to receive each vane of said vanes (18) to a first extent, and at least two shallow portions (19b) arranged to receive each vane of said vanes (18) to a second extent, which is substantially less compared to said first extent, wherein said inner circumferential surface (25) is arranged to receive at least a tip portion of the vanes (18) throughout its whole periphery.

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 machine is disclosed including a sensor on a limb, an implement, an architecture, and a linkage assembly (LA) including a boom and a stick. The architecture comprises one or more LA actuators and a controller that generates a sensor location and offset angle ϕ and is programmed to: pivot the limb (either the boom or stick) about a pivot point and generate a set of sensor signals. The controller is programmed to repeatedly execute an iterative process n times until exceeding a threshold, which process comprises determining a sensor location estimate .sub.n (a distance between the sensor and the pivot point) and an offset angle estimate ϕ.sub.n defined relative to a limb axis. A utilized optimization model includes the set of sensor signals and error terms.

The invention relates generally to hydraulic rotator. More specifically, the invention relates to a system that provides for the successful three hundred and sixty-degree, clockwise or counterclockwise rotation of heavy weights. The system successfully bears the weight of the equipment, the hydraulic rotator, the attachment to the hydraulic rotator and the materials being targeted by the attachment, as well as the torque load and stress produced by the successful three-hundred-and-sixty-degree rotation.

A digging equipment includes a coupling portion coupling the digging equipment to an operating machine, an equipment body having abutment runners with a working surface, a digging tool movably mounted in the equipment body around a rotation axis (R), projecting partially frontally to the abutment runners and peripherally having a plurality of excavation elements. Adjustment means of the excavation depth of the digging equipment are functionally connected to the equipment body and to the digging tool to adjust a relative distance between the abutment runners and the plurality of excavation elements. Articulation means, mechanically interposed between the coupling portion and the digging tool allow the rotation axis (R) to move around an incident or orthogonal tilting axis (T) with respect to the rotation axis (R).
