Abstract

1432256 Trench excavators TELEFONAKTIEBOLAGET L M ERICSSON 19 June 1973 [21 June 1972 20 Feb 1973] 29127/73 Heading E1F [Also in Division H2] Cable is laid in the ground by moving a cutting tool 12 through the ground, to loosen it, by means of a vehicle 10, then moving a laying tool 13, through which cable 14 to be laid extends, through the loosened ground 16, using the vehicle. For the second step the cutting tool is hooked to fitting 131 of the laying tool. The laying tool comprises parallel plates 70, Fig. 7, formed into a plough at one extremity. Cable may be carried by a drum 75 on pivotally mounted arms 72 whose lower ends 142 are formed with a track and shaped to cooperate with a wall 72 connecting the plates 70 to guide the cable.
