Main purpose:

The GFD-2000 reverse circulation crawler drilling rig is suitable for:

Engineering construction such as drilling foundation piles for high-rise buildings, bridges, geological mines, ports, dams, etc

Product features:

This model adopts a mechanical transmission track chassis, which has strong load-bearing capacity, high traction, low noise, smooth, reliable and safe driving, wide application, and is suitable for complex terrain operations. The transfer case, main transmission system, double winch working group, mud pump, drilling tower, etc. are all installed on the track chassis.

This model is a motor-driven mechanical power head with pump drilling reverse circulation drilling rig designed and manufactured by our company. The characteristic of this drilling rig is the power head type, which provides a long travel distance and facilitates the addition of drilling rods without the need for active drilling rods. The power head with pump top suction reverse circulation mud drilling is beneficial for improving drilling efficiency. It has a large operating diameter, high efficiency, strong capability, low construction cost, mature technology, reliable performance, simple operation, convenient use and maintenance, and is particularly suitable for water wells and foundation piles in soil layers, sand layers, pebble sand layers, and soft rock layers. The power head has two speeds and can be used for drilling in different formations. The drill rod has a novel structural form, unique lifting and loosening tools, and convenient and fast connection and disassembly of drill rods. It has two assembly methods: track chassis and car chassis, making it easy to move and position the drilling rig. Convenient for field operations. Hydraulic lift drilling tower, easy to operate, time-saving and labor-saving.

The standard configuration of the drilling rig is driven by a diesel generator set, which can also be connected to an external power source to achieve dual power drilling operations.

This model is a mature product developed by our factory for many years, with stable and reliable performance, and has been highly praised by domestic and foreign customers.

This model of drilling rig has a large torque, high lifting force, strong power, simple operation, convenient and fast addition and removal of drill rods, and high efficiency.
