    1482093 Mining machines SALZGITTER MASCHINEN AG 13 Nov 1974 [9 July 1974] 49161/74 Addition to 1433756 Heading E1F The mining machine of Parent Specification is modified in that the impactor tool-carrying boom includes a variable length structure, e.g. a telescopic structure, instead of being an articulated structure and is pivotally mounted on the or a cross beam of the machine chassis for movement about an axis orientated perpendicular to the said cross beam and to the direction of advance of the machine. Preferably the boom is mounted by a carriage for rotational movement about its longitudinal axis and about upright and horizontal axes on a bridge 30 that is connected about an upright axis to the or one 20 of the cross beams of the self propelled chassis gantry 15 of the machine. Preferably the bridge is' pivotally connected for movement about a further upright axis 27 to a carriage 25 movable along a second 19 of the cross beams. The second cross beam 19 may be located either ahead of or behind the first cross beam 20. The pivot between the bridge and the cross beam may involve an axial rocker bearing 33 in which a guide rod 37 of the bridge is slidably mounted. Movement of the bridge 30 relative to the cross beam(s) of the gantry is controlled by rams 43.

    de coroook, which have welded legs 5 and 6 on the bottom. Side walls 5 and 4 are welded at the top to the top plate 7 and connected to one side of the front plates 8 and 9 on the front side of the upper plate 7 with the screws 10 to the bottom side frame 11 driving machine.
    The top plate 7 is provided with two holes 12 and 13, in which are fixed with screws 14 and 15 parts 16 and 17 of the lifting cylinders 18 and 19.
    The pistons 20 and 21 of the lifting cylinders 18 and 19 are connected to the rods 22 and 23 entering the inside and outside parts / and 2. The piston HITOKH 22 and 23 at their free ends are equipped with fork parts 24 and 25 and the rollers 26 and 27 installed which are driven into the surface of the bottom part 28 of the inner part 2.
    The inner part (see Fig. 2) has two side walls 29 and 20, welded to the bottom part 28, which are connected to one another with the end sides using end plates 31 and 32. Along one part of the upper edge of the side wall 29 and 30 irivarevs against each other, gripping bars 33 and 34, which have a yield of 1O of the inner part 2. On the other side:; the gripping bars 33 and 34, the gripping elements, which are mounted on opposite opposite sides of the integral parts 24 and 25 and are bolted 35 to 36, interact .
    In the outer part / on the hinge 37 and in the inner 2 on the horner 38 from the stand and cylinder and enmesh, 39.
    The gripper, which interacts with the gripping strips 33 and 34, is embodied in the form of rollers 40, attacking fork parts, and, for example, detail 25 (see Fig. 3).
    The outer and inner parts 1 and 2 are supported on the uneven ground 41 (Fig. 4). When the mechanism is in operation, the lift cylinders 18 and 19 are advanced so that the outer part with its lower edge can overcome all the unevenness of the soil 41 without collision. The lifting cylinders 18 and 19 remain in this extended position, if the displacement cylinder 39 is advanced. Due to this, the outer part rolls on the rollers 26 and 27 to the right until
    occupies the position shown in FIG. 6. In this position, the outer part with the help of lifting points, cylinders 18 and 19 is lowered onto the SOIL} 41 and the outer and inner parts / and 2 touch the ground (see Fig. 7). Due to the subsequent retraction of the numerous cylinders 18 and 19, the internal part rises from the ground 41 so that in turn it can overcome all
    soil irregularities. After that, the outer part / remains on the soil 41, and the cylinder is retracted 39 is retracted, and the inner part 2 will not take the right position (see Fig. 9). In this position, the inner part is lowered due to the output of the rods of the lifting cylinders 19 and 18 to touch the ground, and the walking mechanism is mixed inside the walking length. During the working phases, the inner part 2 is enclosed by means of gripping bars and gripping elements (not shown in the drawings) with the help of lifting cylinders 18 and 19.
