 This rig123.net' target='_blank'>drilling rig can be used to drill water wells with a depth of 985ft and wellhead diameter of 1.6 ft. It can also be used to drill the gas wells of the same specification and also can engage in workover operations.
 The water-well drilling rig is a kind of mobile rig. The heavy-duty and cruise chassis is chosen for loading the hoisting/spinning and circulation system integrally, which has a perfect movement.
 With a full hydraulic drive, the operations of this kind of drilling rig, such as hoisting operations, spinning operations, mud circulation and power drive, use a hydraulic loop system. The drilling parameters can realize stepless regulation. 
 The water-well drilling rig also has an auto driller system and high working efficiency, by equipped with a pressure device for pressurization and depressurization to DP.
 A hydraulic brake and a Crown-O-Matic are adopted to meet drilling-process requirements, and an emergency hydraulic source is installed on the chassis to ensure the safety and reliability of the rig.
