XY-4L Core Drilling Rig

XY-4L crawler mounted core drilling rig is a new type of core drilling machine especially suitable for the diamond drilling. XY-4L diamond core drilling rig can be used in engineering geology exploration, hydrology, well, and big caliber construction. 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 crawler mounted core drilling rig 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.
2. XY-4L diamond core drilling rig can export big torsional moment whose intensity is high. Its drilling capability is strong. It can be used in wide range.
3. XY-4L crawler mounted core drilling rig has firm structure by adopting the connecting rod reinforcement spring cramp.
4. XY-4L diamond core drilling rig is 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 crawler mounted core drilling rig carries hydraulic lifting drill tower itself, which is convenient and agile.
6. By adopting crawler type base and four hydraulic rams, the complete machine can be moved by itself conveniently.
