摘要： The invention concerns a hewing or cutting roller (1) with variable cutting width, wherein two pivotable cutting or hewing tool carriers (4, 5) are disposed on at least one lateral end face (2) of the hewing or cutting roller (1), transversely to the axis thereof. One of the tool carriers bears a locking bolt (10) which, in the extended position of the tool carriers (4, 5), co-operates with a hook-shaped locking member on the other tool carrier.

摘要： The invention concerns a partial cutting machine for use as a working or advance heading machine, the machine having a cutting arm which comprises a rotating cutting head, in particular a transverse cutting head, and is mounted so as to be vertically and laterally pivotable on a pivot mechanism of the moving gear frame provided with tracklaying gear. The machine is provided with a loading table, which is disposed on the moving gear frame at the front below the cutting arm, and a central conveyer which extends from the loading table between the moving gear tracks to the rear of the machine where it forms a vertically and laterally pivotable extending ejector arm. The moving gear frame is divided in the longitudinal direction and consists of frame parts which can be pivoted relative to one another in the lateral direction and of which the front part comprises the tracklaying gear, with the pivot arm and the cutting arm, and the loading table, whilst the rear frame part forms the carrier of the extending ejector arm of the conveyor, said arm being laterally pivotable with the rear frame part. The rear frame part is connected to the front frame part via a pivot connection so that it can be pivoted laterally and drawn thereafter. The pivot mechanism with the cutting arm (12) is guided in an axially displaceable manner on the front frame part (1) in the direction of the working face and in the opposite direction by means of an advance cylinder device (20). The pivot connection (3) is disposed between the two moving gear frame parts (1, 2) at a spacing behind the tracklaying gear (4) of the front frame part (1). The front frame part (1) is provided with claws (7, 11) which relieve the load on the tracklaying gear (4) during cutting and can be extended towards the worked stratum (10).

摘要： The invention relates to a device for damping vibrations in part-face cutting machines (1), comprising an extension arm (3) pivoting round two axes (5, 9) with cutting tools (7) rotationally fitted thereon. Said device has a hydraulic regulating drive mechanism (6) which is impinged upon by fluid via a valve arrangement. Sensors (13 or 14) are provided in order to detect vibrations, accelerations, load and/or position of the cutting arm (3) and which trigger a corresponding compensation of the regulating drive mechanism formed by the hydraulic cylinder piston units (6) by means of a control device (16). The position of the extension arm (3) is thus kept basically constant round the vertical rotational axis (9) when the swing gear swivels.

摘要： The invention provides for renovation of railroad track installations through the use of a sliding shield driver (9) which in the work area secures the trench (6) formed by the removal of the old track foundation and, as the renovation work advances, travels in the direction of the old track to be renovated. The sliding shield driver (9) has lateral shields (15) securing the trench walls as well as ground shields (13) resting on the trench bottom; these shields are linked to the base frame (10) of the shield driver via hydraulic shield cylinders. Preferably, the shield driver consists of a header frame and a trailer frame with trailer shields (20) pivotably attached to the lateral shields (15) at the trailer frame (19). The lateral shields with the trailer shields are of such a length as to secure the trench walls over the entire work area.

摘要： In a cutting control process for kirving tools (6) on advance working machines (2), the depth of cut of the kirving tool (6) is detected and the measurement data for the depth of cut are linked to a control unit in which the geometry of the winning tool is stored and measurement data for load-bearing capacity are taken into account. To carry out the process a device is provided for detecting the depth of cut of kirving tools (6) of advance working machines (2) into the rock face, said device comprising in the forward region of the advance working machine (2) at least one proximity sensor (7) directed to the rock face and connected to an evaluation unit.
