Description

A chain trencher cuts with a digging chain or belt that is driven around a rounded metal frame, or boom. It resembles a giant chainsaw. This type of trencher can cut ground that is too hard to cut with a bucket-type excavator, and can also cut narrow and deep trenches. The angle of the boom can be adjusted to control the depth of the cut. To cut a trench, the boom is held at a fixed angle while the machine creeps slowly.

The chain trencher is used for digging wider trenches (telecommunication, electricity, drainage, water, gas, sanitation, etc.) especially in rural areas. The excavated materials can be removed by conveyor belt reversible either on the right or on the left side.

There are various methods for excavating trenches in rock – principally drill and blast, hydraulic breakers and chain trenchers. Selection of a trench excavation method must take into account a range of rock and machine properties.

Micro trencher
A micro trencher is a "small rockwheel" specially designed for work in urban area. It is fitted with a cutting wheel that cuts a microtrench with smaller dimensions than can be achieved with conventional trench digging equipment.

Microtrench widths range from about 30 to 130 mm (1.2 to 5.1 in) with a depth of 500 mm (20 in) or less. These machines are sometimes radio-controlled. With a micro trencher, the structure of the road is maintained and there is no associated damage to the road. Owing to the reduced trench size, the volume of waste material excavated is also reduced. Micro trenchers are used to minimize traffic or pedestrian disturbance during network laying.

Tractor-mount trencher
A tractor-mount trencher is a trenching device which needs a creeping gear tractor to operate. This type of trenchers is another type of chain trencher. The tractor should be able to go as slowly as the trencher's trenching speed.

Portable trencher
Landscapers and lawn care specialist may use a portable trencher to install landscape edging and irrigation lines. These machines are lightweight (around 200 pounds) and are easily maneuverable compared to other types of trenchers. The cutting implement may be a chain or a blade similar to a rotary lawn mower blade oriented so that it rotates in a vertical plane.
