Rockwheel Trenchers


New Aardvark Rototrench R.W.T 75 S Rock Wheel Trenching Train


750mm DEEP X 60 TO 135mm CUT

Trenching Train System digs trench, conveys away spoil, lays pipe or cable & backfills all in one pass at work rates of up to 600 linear metres per hour.


Robust & proven mechanical tractor P.T.O. drive ensures ground penetration even in the toughest of geological stratas.


Epicyclical final reduction gives massive torque magnification to the wheel & carbide teeth just where it is needed.
