摘要： The self-propelled construction machine according to the invention, in particular road-milling machine, recycler, stabiliser or surface miner, comprises a machine frame 2, which is supported by a chassis 1, which has wheels or tracks 1A, 1B. A milling drum 4 is arranged on the machine frame. The wheels or tracks 1A, 1B and the milling drum 4 are driven by a drive unit 8. Furthermore, the construction machine comprises a control unit 19 for controlling the drive unit 8 and a signal-receiving unit 18 for detecting at least one measurement variable M(t) which is characteristic of an operating state of the milling drum 4. The construction machine is characterised in that the rotational speed of the milling drum 4 is adapted, on the basis of at least one measurement variable M(t) which is characteristic of a critical operating state of the milling drum, to the operating conditions of the construction machine in such a way that the milling drum is operated in a non-critical operating state. The adaptive open-loop control of the milling drum rotational speed allows the construction machine to be operated at an optimum operating point with respect to the milling drum rotational speed.

摘要： A communicator in one aspect of the present disclosure includes a connector, a communication circuit, and a communication controller. The connector is electrically coupled to an electric working machine. The communication circuit performs wireless communication. The communication controller cyclically transmits operational information without specifying a recipient via the communication circuit in response to an operating mode of the communication controller being set to an operation-transmission mode. The operational information indicates an operating state of the electric working machine.

摘要： A method for controlling a wall saw system during creation of a separation cut in a workpiece between a first and second end point, is disclosed. The separation cut is carried out in a plurality of main cuts. In addition to the main-cut sequence, an overcut sequence having at least two overcuts is defined for each end point defined as a free end point. For each overcut sequence, a starting position and an end position are defined, the overcuts being carried out therebetween. The wall saw is positioned in the starting position and is pivoted into a first overcut angle; subsequently, the saw head is moved by way of the inclined saw arm until the end position has been reached. The wall saw is displaced back into the starting position and pivoted into a second overcut angle. This sequence is repeated until all of the overcuts have been carried out.

摘要： A method for controlling a wall saw system during the creation of a separating cut in a workpiece. The movement of the saw head is controlled at the end points such that a boundary of the wall saw facing the end point coincides with the end point after the pivoting movement of the saw arm. In the case of a free end point, the boundary of the wall saw is formed by an upper exit point of the saw blade. In the case of an obstacle, the boundary of the wall saw is formed by the saw blade edge of the saw blade if the processing occurs without the blade guard or by the blade guard edge of the blade guard if the processing occurs with the blade guard.

摘要： A numeric-control work center can be used for carrying out cutting operations or grinding and/or milling operations on plates of stone, marble, or, in general, natural or synthetic stone material, or ceramic material. The work center comprises at least one working head movable along at least two mutually orthogonal horizontal axes on a work surface. The work surface includes a rigid supporting board, which defines a first planar supporting surface, and a series of sacrificial elements rigidly connected to the rigid supporting board. The sacrificial elements are arranged in positions spaced apart from each other and define a second supporting surface located at a higher level than the first planar supporting surface, so that a cutting tool coupled to the working head engraves the sacrificial elements, without interfering with the supporting board during a cutting operation on a plate resting on the sacrificial elements, whichever is the path followed by the cutting tool. Between the sacrificial elements there remain free portions of the planar surface of the supporting board, so that they can be removably engaged by one or more blocks for supporting and holding the plate. These blocks project above the sacrificial elements and are adapted to define a third supporting surface, located at a higher level than the second supporting surface, for supporting and holding a plate during a milling or grinding operation on the plate.

摘要： A self-contained truck-mounted brick laying machine (2) is described. A truck (1) supports the brick laying machine (2) which is mounted on a frame (3) on the truck chassis. The frame (3) supports packs or pallets of bricks (52, 53) placed on a platform (51). A transfer robot can then pick up an individual brick and move it to, or between either a saw (46) or a router (47) or a carousel (48). The carousel is located coaxially with a tower (10), at the base of the tower (10). The carousel (48) transfers the brick via the tower (10) to an articulated (folding about horizontal axis (16)) telescoping boom comprising first boom element in the form of telescopic boom (12, 14) and second boom element in the form of telescopic stick (15, 17, 18, 19, 20). The bricks are moved along the folding telescoping boom by linearly moving shuttles, to reach a brick laying and adhesive applying head (32). The brick laying and adhesive applying head (32) mounts to element (20) of the stick, about an axis (33) which is disposed horizontally. The poise of the brick laying and adhesive applying head (32) about the axis (33) is adjusted and is set in use so that the base (811) of a clevis (813) of the robotic arm (36) mounts about a horizontal axis, and the tracker component (130) is disposed uppermost on the brick laying and 110,111 adhesive applying head (32). The brick laying and adhesive applying head (32) applies adhesive to the brick and has a robot that lays the brick. Vision and laser scanning and tracking systems are provided to allow the measurement of as-built slabs, bricks, the monitoring and adjustment of the process and the monitoring of safety zones. The first, or any course of bricks can have the bricks pre machined by the router module (47) so that the top of the course is level once laid.
