1. Characteristics of XYX-3 wheeled hydraulic water well drilling rig

·The drilling rig is equipped with wheeled walking mechanism and hydraulic cylinder support, which is convenient for the whole machine to be relocated and easy to adjust the level of the drilling rig.

·Using the ball card holding mechanism to replace chuck,can implement non-stop down rod,convenient operation,safe and reliable.

·With oil pressure feeding mechanism to improve drilling efficiency

·The pressure gauge is provided with the pressure gauge of the bottom of the hole, so it is easy to master the hole in the hole.

·The lifting and falling tower is hydraulic operation, which is convenient and reliable.

·The diesel engine uses electric start to reduce the labor intensity of the worker.
