Device for laying and perfectly aligning modular prefabricated parts, in the form of ducts or pipes, especially those intended to receive electrical or other types of cable

摘要

A roller chute 2, along which fall a succession of parts 1, carries at A a hinged structure 3, with an attitude that can be adjusted by means of the tie rod 10, shaped and equipped to produce the trench in the ground and lay the parts 1 in it. To the structure 3 is hinged at B a fork 6 carrying a rubber tyred wheel 7 that rests by gravity on the parts 1 and is driven by its own motor 9 so that it exerts sufficient pressure on the emerging parts to ensure that they are perfectly laid. To the fork 6 are hinged the arms 11 of a carriage 12 whose wheels 13 run on the parts 1 to complete and check their perfect positioning. IMAGE
