<p>The machine can be permanently or detachably attached to a motor vehicle, for various work to be carried out on roadside embankments, esp. under guide-rail boards, on either side of the road. The attachment unit (1), for joining to front or rear, carries running and/or sliding rails (3) at a horizontal slope, which is adjustable, and these in turn accommodate a movable carrier or frame (4), with rails (8) or a slide adjustably set at right angles to it. A plate (25) on these is fitted with a fixture for selective accommodation of various working appliances, which operate where required relative to the vehicle, and are stored above or behind it when at rest. They are surrounded by a contact frame equipped for the transmission of optical, acoustic or radio wave impulses or control instructions, the devices being mechanically or hydraulically driven.</p> |
