dakota excavator, 2017-12-29 03:05:15. Excavator is the machine that can excavate the soil of various types forcefully and then using hydraulic system a hydraulic force is generated and utilizing this force bucket is pull back towards the machine. Bucket of excavator is replaceable. If front bucket is exchange with some other attachments then excavator can be used for multi-purpose. For example: pile diver, hydraulic jack hammer etc…

dakota excavator, 2017-12-29 03:06:03. The fundamental mechanism of an excavator consists of the undercarriage that includes the tracks, track frame, blade and the finalexcavator track (components) drive. The final drive has a hydraulic motor and gears that provide drive to the tracks. The operators cabin, engine, counterweights, hydraulic and fuel tanks are attached to the undercarriage, enabling the excavator to swing 360° without any hindrance.

Larger rigs are capable of drilling through thousands of metres of the Earth s crust, using large "mud pumps" to circulate drilling mud (slurry) through the drill bit and up the casing annulus, for cooling and removing the "cuttings" while a well is drilled.

Rigs can range from 100 ton continuous flight auger (CFA) rigs to small air powered rigs used to drill holes in quarries, etc. These rigs use the same technology and equipment as the oil drilling rigs, just on a smaller scale.

This can be counteracted, however, with the use of "stabilizers" also known as "reamers", which are large cylindrical pieces of steel attached to the drill string, and made to perfectly fit the size of the hole being drilled. These have sets of rollers on the side, usually with tungsten buttons, that constantly break down cuttings being pushed upwards.

Other equipment can force acid or sand into reservoirs to facilitate extraction of the oil or natural gas; and in remote locations there can be permanent living accommodation and catering for crews (which may be more than a hundred). Marine rigs may operate thousands of miles distant from the supply base with infrequent crew rotation or cycle.

Hollow stem auger drilling is used for softer ground such as swamps where the hole will not stay open by itself for environmental drilling, geotechnical drilling, soil engineering and geochemistry reconnaissance work in exploration for mineral deposits.
