The common feature of these devices is that the degree of automation is getting higher and higher, and some functions realize the application of intelligent i GPS technology on these RIGS, which realizes the automatic positioning of the boom, saves the time of field marking and positioning, improves the efficiency of the operation, and enables the operator to concentrate on monitoring the process of drilling. At the same time, more attention is paid to safety and environmental protection and the improvement of human-machine relationship. With the impact of the implementation of engine emission regulations, mobility, intelligent handling and environmental regulations Tier 3/ Euro ⅢA emission regulations, most foreign rig manufacturing companies have adopted diesel engines that meet the emission standards.

Sandpumpen werden verwendet, um abrasive Materialien wie Sand, Kies oder Schlamm zu transportieren. Sie kommen häufig in der Bauindustrie zum Einsatz, beispielsweise beim Aushub von Fundamenten oder dem Transport von Baumaterialien. Auch in der Bergbauindustrie sind sie von großer Bedeutung, da sie dabei helfen, Rohstoffe effizient zu fördern und zu verarbeiten. Zudem spielen Sandpumpen eine entscheidende Rolle in der Umwelttechnik, etwa bei der Sanierung von kontaminierten Böden.

1.Downhole drilling machine: When drilling a downhole gun hole with a aperture less than 150 mm, in addition to the application of a rock drill, it can also be used to drill a small diameter of 80 ~ 150 mm. When drilling a gun hole with a diameter of less than 70 mm in coal or softer mineral rock, it is generally used to drill or air drill, driven by a motor (or air motor) to drill the drill pipe, and the rock (coal) chips drilled out are discharged through the spiral groove on the drill pipe.

Roof covering is a vital component of any building, serving both functional and aesthetic purposes. Functionally, it shields the interior from rain, snow, wind, and other environmental factors. A well-designed roof covering can prevent moisture penetration, reduce heat gain, and enhance energy efficiency—leading to lower utility bills and a more comfortable indoor environment. Aesthetically, the roof contributes significantly to a building's character, influencing its overall design and style.
