TRENCH CUTTER USING ENDLESS CUTTER CHAIN

摘要

Trench cutting apparatus particularly for cutting deep narrow trenches has a power-driven endless cutter chain on an elongated chain support which is linearly movable in a carrier mounted on a vehicle. In operation the carrier is vertical (or inclined to the vertical if a sloping trench is required) and is held in position by adjustable rams which permit the cutter to be positioned across the width of the vehicle as required and serve to maintain the carrier in the required plane.
