Base machine, usually a crawler crane, of adequate capacity Hose handling system, for both hydraulic and slurry hoses; these systems can use either a hose drum or a hose tension design Hydraulic cutter, which typically consists of two cutter wheels powered by a hydraulic motor , a slurry pump , and flaps to control its direction in case of ...
Drilling a blast hole with a pneumatic drill (jackhammer). A pneumatic tool, air tool, air-powered tool or pneumatic-powered tool is a type of power tool, driven by compressed air supplied by an air compressor. Pneumatic tools can also be driven by compressed carbon dioxide (CO 2) stored in small cylinders allowing for portability. [1]
Gas cushion (spring) pre-filled accumulators of liquids are called hydropneumatic accumulators. "Hydro" because a liquid (like water) is involved. "Pneumatic" because a gas (like air) is involved. "Accumulator" because the purpose is to store or accumulate liquid volume by easy compression of the gas.
The usual recoil system in modern quick-firing guns is the hydro-pneumatic recoil system. In this system, the barrel is mounted on rails on which it can recoil to the rear, and the recoil is taken up by a cylinder which is similar in operation to an automotive gas-charged shock absorber , and is commonly visible as a cylinder mounted parallel ...
A mud gun is commonly used to guard against precipitates in a solids control system. The mud gun is installed in a mud tank. Furthermore, it is usually used together with mud agitator. The mud agitator is used in the middle of the tank while the mud gun is placed in the corner of the tank. [1] [2]
The first known patent application is from Christopher G. Cross in 1873 for "Drills for Boring Artesian Wells", [1] followed in 1884 by the brothers Morris and Clarence Baker for a "Machine for Operating Drills" [2] The methods used to direct the well path fall into two broad categories, these being “push-the-bit” or “point-the-bit ...
A magnetic drill is a portable machine for drilling holes in large and heavy workpieces which are difficult to move or bring to a stationary conventional drilling machine. It has a magnetic base and drills holes with the help of cutting tools like annular cutters (broach cutters) or with twist drill bits. There are various types depending on ...
Since 1993, RSP UK Suction Excavators Ltd. has produced suction structures mounted onto two, three, and four-axle vehicles, stationary suction units, and custom-made machines. [3] Pacific Tek, [ 4 ] also founded in 1993, has created the Angled Vacuum Excavator Tank (1997) and the 180° Swivel Mount Valve Operator (1999).
