摘要： A framework comprises a laser distance meter (LDM), reflector, and excavator comprising a boom, a stick, boom and stick sensors, implement, and a controller. The LA comprises a boom and stick defining LA positions. The LDM is configured to generate a DLDM and θINC between the LDM and the reflector, and the controller is programmed to generate θB at a plurality of boom positions, generate θS at a plurality of stick positions, and calculate a height H and a distance D between a node on the stick and the LDM based on DLDM and θINC, build a set of H, D measurements and a corresponding set of θB, θS, and execute a linear least squares optimization process based on the H, D set and corresponding set of θB, θS to determine and operate the excavator using LB and LS.

摘要： A common connection apparatus for coupling a power tool to an extensible arm and a power supply, the apparatus including a tool support base designed to support a tool, and a power supply support base designed to be affixed to the end of the extensible arm. The tool support base and the power supply support base each include a plurality of power connectors, positioned for engagement when the bases are aligned. The tool support base also has an alignment stab, which is received within a channel of the power supply support base. A plurality of pins are further positioned on the tool support base, to be received in apertures of the power supply support base. By this configuration, the bases may be aligned and engaged, facilitating the transmission of power from the machinery to which the arm is affixed, to the tool.

摘要： A quick hitch for coupling and decoupling a tool at a rotator for rotating the tool that has a rotator attachment part that is attachable to an excavator arm or the like and that has a rotary rotator part rotatable relative thereto, wherein the quick hitch has a coupling part at the rotator side that is fastenable to the rotatable rotary rotator part and has a coupling part at the tool side, wherein the two coupling parts can be brought into engagement with one another and can be latched to one another by at least one latch element. A latch operating actuator is provided at the rotator attachment part for actuating a latch adjustment part movably arranged at one of the coupling parts for the unlatching and/or latching of the latch element, the latch operating actuator being rotatable about the rotator axis of rotation relative to the latch adjustment part.

摘要： A hydraulic excavator is equipped with a bucket, a tilt cylinder, a fourth stroke sensor, and a bucket information computing unit. The bucket is able to rotate about the center of a tilt axis. The tilt cylinder causes the bucket to rotate about the center of the tilt axis. The fourth stroke sensor detects a stroke length of the tilt cylinder. The bucket information computing unit obtains a tilt angle of the bucket on the basis of the stroke length detected by the fourth stroke sensor.

摘要： The invention concerns a demolition arrangement for a remote-controlled working machine (1) equipped with a manoeuvrable arm (9), which machine, electrically powered and able to be driven on tracks (17), is principally intended for destruction and demolition work through the demolition processing with an impact tool (50) that operates through a hydraulically powered hammer (32) and where an operator walking next to the machine controls its various movements with a remote-control unit (4), which machine has a chassis (5) with an upper part (6) that is mounted in bearings on a lower part (7) in a manner that allows rotation for the rotation of the upper part in a horizontal plane around a vertical axis (8), whereby the manoeuvrable arm is supported at the upper part and including a series of arm parts (10, 11, 12) mutually joined to each other and that can be manoeuvred in a vertical plane by associated hydraulic cylinders (13, 14, 15), a link system (20) arranged at the free end of the arm that can be adjusted by means of a hydraulic cylinder (29) and designed as a combination of a coupling arrangement (21) for the attachment of a tool and a tilt or demolition arrangement (22) for the controlled oscillation around the centre of an axis (23) at the free end of the manoeuvrable arm of an impact tool inserted into the hammer. In order to make the work of demolition efficient, a rotary joint (35) is arranged at one of the arm sections (12) that are a component of the manoeuvrable arm (9), which rotary joint allows, through the influence of a rotator (36) a forward arm subsection (12:2) of the arm section, on which arm subsection the link system (20) is located, to place the end of the impact tool (50) that is located farthest forward against a working point in space though the forward arm subsection (12:2) being rotated around the longitudinal axis (A) of the arm section (12).

摘要： A multiple tool attachment system is adapted to be attached to demolition equipment. The system includes a universal body attached to the demolition equipment. A series of tools are independently attachable to the universal body. The universal body includes a guide slot extending longitudinally along the universal body. Each tool generally includes a pair of pivotable jaws adapted to be pivotably attached to the universal body with at least one linkage extending from the universal body and attachable to each jaw of the tool. A slide member is received within the guide slot, with each linkage attached to the slide member, and a piston cylinder arrangement is attached to the universal body and coupled to the slide member for moving the slide member and the jaws. The multiple tool attachment system is provided with quick change features and is designed to optimize the cutting characteristics throughout the movement cycle.
