and steel rope
A steel rope (Fig. . ) connects the plough to the traction vehicle and the latter can be
supported on the ground by means of a support plate, to enable the tractive forces to be
transmitted into the ground. The string of ductile cast iron pipes, which is connected by
longitudinal force-fit joints, is laid out along the line of the run. The string is then hooked
onto the widening body (Fig. . ) and is ploughed into the earth (Fig. .7) from a launch
pit with an inclined ramp (Fig. . ). The length of the launch pit depends on the angular
deflection of which the longitudinal force-fit restrained joints are capable.
