According to the United States Army, there are several methods by which combat engineers can dig an anti-tank ditch on the battlefield. Using only hand tools, a platoon of soldiers can dig a triangular-shaped ditch 100 feet (30 m) long, 12 feet (3.7 m) wide and 6 feet (1.8 m) deep in seven and a half hours; a trapezoidal-shaped ditch of similar ...
– The machines are laying out the site for a new park When Diggs and Scooch see the plans they figure they can save Bozer some time and just get on with it themselves. But when they manage to dig a perfectly good pond - in completely the wrong place - it's going to take some clever thinking to solve the problem before Bozer finds out.
A bulldozer or dozer (also called a crawler) is a large, motorized machine equipped with a metal blade to the front for pushing material: soil, sand, snow, rubble, or rock during construction work. It travels most commonly on continuous tracks , though specialized models riding on large off-road tires are also produced.
Power shovels normally consist of a revolving deck with a power plant, drive and control mechanisms, usually a counterweight, and a front attachment, such as a crane ("boom") which supports a handle ("dipper" or "dipper stick") with a digger ("bucket") at the end. The term "dipper" is also sometimes used to refer to the handle and digger combined.
Buckets have numerous shapes and sizes for various applications. There are also many other attachments that are available to be attached to the excavator for boring, ripping, crushing, cutting, lifting, etc. Attachments can be attached with pins similar to other parts of the arm or with some variety of quick coupler.
“The pond is completely surrounded by sand and he was up on the embankment,” Hunt said. “It looks as though some of the sand gave away and his dozer rolled backwards.”
The M9 armored combat earthmover (ACE) is a highly mobile armored tracked vehicle that provides combat engineer support to frontline forces. Fielded by the United States Marine Corps, and the United States Army, its tasks include eliminating enemy obstacles, maintenance and repair of roads and supply routes, and construction of fighting positions.
The workgroup of a compact hydraulic excavator consists of the boom, dipper or arm, and attachment (e.g. auger, bucket or breaker). It is connected to the front of the excavator's house structure via a swing frame that allows the workgroup to be hydraulically pivoted left or right to achieve offset digging for trenching parallel with the tracks.
