Hydraulic control of four legs, the rear forging and casting legs can be horizontally telescopic, four legs can be operated at the same time, improve the flexibility of the rig, convenient for rapid adjustment of the car body. Sand pump gate valve is equipped with pneumatic control, drilling mortar pump, mortar pump can be used to switch, to achieve forward and reverse drilling. The working platform is spacious, suitable for drilling on mud, loose layer, pebble layer and foundation along the layer, building foundation pile hole, highway, railway, bridge pile, foundation pile hole, oil field casing, high pressure line pile, wind farm bottom pile, geological mine, port wharf, dam foundation and other foundation construction. It can also be used for drilling industrial and agricultural Wells. The machine relies on a car engine to drive all the power, which saves a lot of fuel for casting and forging. Only three people are needed on the construction site, and no manual work is needed. Beautiful appearance atmosphere, rotary torque, fast footage, favored by domestic and foreign customers. The original product is reformed to save energy and the transmission structure of the original generator is changed. The original use of two engines to use a drill engine, which can reduce fuel consumption, to achieve the effect of energy saving and emission reduction, but also can reduce the repair and maintenance costs of the machine, so that the use of the cost of the product is greatly reduced. (2) Developed a new product: 300 meters deep well drilling machine, suitable for deep underground water level area, with low cost, reliable use, wide use and other characteristics.
