EXCAVATING AND PIPE LAYING MACHINES

摘要

A pipe laying machine comprises a vehicle carrying a trench excavator followed by a pipe laying box (10) running in the trench. Pipe lengths are stored in the pipe laying box one above another and the lowermost pipe length is periodically released by movement of bars (48, 50) into the bottom of the pipe laying box and is pressed by a ram (6) into the mouth of the last laid pipe length.
