Excavators are also called diggers, scoopers, mechanical shovels, or 360-degree excavators (sometimes abbreviated simply to "360"). Tracked excavators are sometimes called "trackhoes" by analogy to the backhoe. In the UK, wheeled excavators are sometimes known as "rubber ducks". OverviewExcavators are primarily consisting of a , dipper (or stick), , and cab on a rotating platform known as the "house". The modern excavator's house sits atop an undercarria. .
Modern hydraulic excavators come in a wide variety of sizes. The smaller ones are called mini or . For example, smallest mini-excavator weighs 2,060 pounds (930 kg) and has 13. [pdf]
A drifter drill, sometimes called a rock drill, is a tool used in mining and civil engineering to drill into rock. Rock drills are used for making holes for placing dynamite or other explosives in rock blasting, and holes for plug and feather quarrying. While a rock drill may be as simple as a specialized form of chisel, it may also take the form of a powered machine. The mechanism may be worke. History and typesThe simplest form of rock drill consists of a long chisel or drill steel that was struck with a . , who worked unsuccessfully as a silver miner in the early 1860s before taking up journalism, described t. .
In reciprocating power drills, the drilling cylinder is mounted on a feed-screw, such that as the hole is drilled and the drilling point recedes from the rock face, the drill-bit continues to move into it, while the anchor point (on th. [pdf]
A mud pump (sometimes referred to as a mud drilling pump or drilling mud pump), is a reciprocating piston/plunger pump designed to circulate drilling fluid under high pressure (up to 7,500 psi or 52,000 kPa) down the and back up the . A mud pump is an important part of the equipment used for oil well drilling. [pdf]

The screw compressor is identical to the screw pump except that the pockets of trapped material get progressively smaller along the screw, thus compressing the material held within the pockets.OverviewA rotary-screw compressor is a type of , such as an , that uses a rotary-type positive-displacement mechanism. These compressors are common in industrial application. .
Rotary-screw compressors use two very closely meshing spiral rotors to compress the gas. In a dry-running rotary-screw compressor, timing gears ensure that the male and female rotors maintain precise alignment. .
The capacities of rotary-screw compressors are typically rated in (HP), ()* and (PSIG.) For units in the 5 through 30 HP range the physical siz. [pdf]
As said before, oil-free screw compressors used two stages, with an intercooler to reach the desired end pressure. But why is it so difficult, in this age of computer-aided design, robot controlled cnc-mac. [pdf]

But the air end needs a power source to operate, which is where the diesel engine comes in. A diesel driven engine converts diesel fuel into motion, forcing the air end to move and the system to compress air. .
When you turn on the engine, the battery powers the pistons in the cylinder up and down. The pistons push the air through the cylinders, into a combustion chamber where it is. .
While the above process occurs, additional fuel is delivered by the system. The fuel is pumped from the fuel tank, passing through filters, a higher pressurization pump,. .
During the ignition process, air is also pumped to the cylinders. On some engines, this air passes through a simple air cleaner en route. [pdf]
