The 300 type water well drilling rig is a light, efficient and multifunctional crawler-type full hydraulic drilling rig. It is high efficiency because of having a larger torque of the turntable and is mainly used for water well in industry and agriculture, national defense building foundation, geological exploration, geothermic well and other foundation working, it is popular at home and abroad.
SL330S can drill holes in different strata (rock layer, mud layer, sand layer), and the maximum diameter can reach 330mm.Unique bump design and centralized control operating system are easy to maintain and operate.This machine adopts excavator crawler chassis, which has high off-road performance and can also be installed on trucks, with stronger mobility.
Zhengyuan Serises crawler mounted drilling rig can drilling in all kinds formations by mud drilling in soft formation and air DTH hammer in rock drilling,DTH Hammer is applied in rock drilling, slag is discharged by air pressure and the offstage efficiency is ten times than traditional rotary drilling.
Zhengyuan Serises deep water well drilling rigs, in cutting drilling or rotary drilling can be operated in unconsolidated layer,and the slag can be discharged under by mud, the impact drilling operation can also be adopted and slag can be discharged by pressure air, the hydraulic water well drilling rig suitable for drilling complicated geological conditions.
