XY-4L drill is a new type core drilling machine. It can meet the new multi-drill technics and suit for multi- vocations, especially for the diamond drilling. It can be used in engineering geology exploration, hydrology, well, and big caliber construction It’s a spindle type drill. It has inherited many merits from the former type, such as simple structure, easy operation, and convenient maintenance. Except for the above merits, there are also some outstanding advantages as follows:
1. XY-4L drill has many velocity shelves which are distributed in reason. It can meet the demand of various high efficiency drilling technics such as diamond rope sampling, impact gyration, directional drilling, reverse circulation consecutive coring (sampling) and so on, and conventional method’s aperture matching. It suits for multi-drill technics.
2. XY-4L drill can export big torsional moment whose intensity is high. Its drilling capability is strong. It can be used in wide range.
3. Adopting the connecting rod reinforcement spring cramp and hydraulic pressure loosen normal close chuck whose structures are novel and compensate performance is good and hard alloy welded on spider, the clamping can be with large force, longevity and high reliability.
4. Equipped with the brand automobile’s gearbox, clutch, universal transmission shaft and other high quality general parts which leads to long-life, high reliability and convenient replacement.
5. XY-4L drill carries hydraulic lifting drill tower itself, which is convenient and agile.
6. Adopting crawler type base and with four hydraulic rams the complete machine can be moved by itself conveniently.
