c. Trenching machines. Trenching machines can quickly dig trenches and give better accuracy in terms of depth and width. A suitable speed can be chosen for any job as the machine is crawler-mounted with a wide range of speed. Wheel-trenchers and Ladder-type trenchers are the two types of trenching machines.
