SPT-300 drilling rig adopts turntable rotation, composed of main and auxiliary winch, gearbox, drilling tower, chassis, etc., hydraulic tower, wide variable speed range, easy operation, complete functions, stable and reliable performance, compact structure, easy disassembly and assembly, suitable for industrial and agricultural water well drilling, hydrogeological survey and bridge pile engineering hole drilling.
• The 300 type drilling rig is a trailer-type water well drilling rig, which can be pulled and moved by tractors such as tractors, so the relocation is convenient and fast, and the mobility is good.
• The drilling rig is suitable for the drilling construction of high-rise buildings, bridges, geological mines, ports, dam foundations, water well construction, complex ground source heat pumps, etc.;
• The rig is equipped with four hydraulic outriggers, which can be operated simultaneously or individually, facilitating rapid leveling of the rig. And the two rear legs can be extended horizontally, which improves the stability of the entire drilling rig. Borrowing hydraulic cylinders to start the tower, it is convenient, reliable and simple to use, and meets the construction needs of different working conditions to the greatest extent;
• The drilling rig is simple to operate, strong in use, easy to maintain, less in investment and quick in effect, which is the best choice for users.
