ST 450 Pneumatic Borewell Machine Fetures:
Various drilling technologies can be used on this drill, such as down the hole drilling, mud drilling, cone drilling, pipe following drilling and core drilling under development. The drilling rig can be equipped with mud pump, generator, electric welding machine and cutting machine according to the needs of users. High operation efficiency: due to the full hydraulic and top drive rotary propulsion lifting, it is suitable for various drilling processes and drilling tools. It has the advantages of convenient and flexible operation, fast drilling speed and short auxiliary time, so the operation efficiency is high. Low cost: DTH hammer drilling technology is mainly used for drilling on rock. DTH hammer rock drilling has high efficiency and the lowest drilling cost per meter. High outrigger crawler type: high outrigger is convenient for loading and transportation, and can be loaded directly without crane. Crawler walking is more suitable for muddy field movement. Function of oil mist device: the down the hole hammer drilling technology is mainly used in rock drilling. The down the hole hammer has high rock drilling efficiency, longer service life of the lubricated impactor and low drilling cost per meter. Drilling rig chassis: it can be crawler type self-propelled chassis or vehicle mounted self-propelled chassis.
