KW300 Water well drill rig is our hot sale products and have a very good reputation in our customers, in real drilling test, we drill a 219mm diameter , the depth reached to 325 meters, we believe the final depth can reach to 350 meters.
 
The Main Technical Advantages of KW300 as follow:

The drilling depth for one time can reach 6.6 meters, which save the time to load the drill pipes and also save the human resources;
Adopting double cylinder to lifting, lifting force can reach 20 tons;
The four strong legs can lift 1.7meters, and the real ground clearance can reach 1.45 meters, which easy to stable the machine and convenient for the loading during the transportation;
KW300 water well drill rig equipped with a multi-function generator that can be used to generate electricity or to drive other tools, also equipped high-pressure pumps for a variety of applications.

More Features:
1.Equipped with 84KW Yuchai brand turbocharged engine, strong power;
2. Patented design composite boom, double cylinder lift, long stroke, large tonnage
3. The main boom of each rig is equipped with a stopper to protect the cylinder;
4.Drilling machine chassis: professional excavator chassis ,durable,heavy bearing capacity,wide chain plate, less damage to hard road.
5.Parallel gearbox design, separate oil pump, sufficient power supply, reasonable distribution, unique design of hydraulic system, simple maintenance and low cost
6. The travel motor is equipped with reducer, durable and long service life;
7.Fast distribution valve: the speed of three gears up to 150-160 rpm, basically achieve the dual-use function of water and air
8. Each hydraulic hose is covered with soft management set to make the hose last longer.
9. The rig power is driven by the diesel engine, and the rig's walking, turning, propulsion, lifting, outriggers, and unloading rods are all controlled by hydraulic pressure.
10.The rig's walking is a crawler-type self-structure, which is easy to move. Its rubber crawler-type chassis makes it easy to walk in the city and the courtyard, and it is not easy to damage the ground.
11.High and Strong hydraulic legs allow quick and stable adjustment of the rig's body level for easy loading and unloading and shifting positions.  
12.Dedicated wellhead setting provide a the certain center for drilling to ensure the  vertical opening and positioning accuracy
13.Mechanical positioning of the carriage and frame improves the stability of the carriage
14.The pneumatic system has a custom oil injector that lubricates the impactor, effectively increasing the life of the impactor.
