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]

Excess pressure is relieved by allowing the pressurized fluid to flow from an auxiliary passage out of the system. The relief valve is designed or set to open at a predetermined set pressure to protect and other equipment from being subjected to pressures that exceed their design limits. When the set pressure is exceeded, the relief valve becomes the "" as the valve is forced open and a portion of the fluid is diverted through the auxiliar. [pdf]
In the oil industry, waterflooding or water injection is where is injected into the oil reservoir, to maintain the (also known as voidage replacement), or to drive oil towards the wells, and thereby increase production. Water injection wells may be located on- and offshore, to increase oil recovery from an existing reservoir. Normally only 30% of the oil in a reservoir can be extracted, but water injection increases the re. [pdf]
