China 350m Crawler Mechanical Top Drive Water Well Drilling Machine Equipped Mud Pump or Compressor

1.JDL-350 mechanical top drive drilling rig equipped with mud pump or compressor for water well, geological exploration or core

JDL-350 drilling rig is a mechanical top-drive drilling equipment , Which can be equiped with mud pump to slove the slow drilling speed at hard rock layer, and air compressor to slove the slow drilling at clay layer.

Features

· Crawler type with good off-road capacity

· With four hydraulic square tube high outriggers, good stability .

· Equipped with drill rod holders and foot pedals in left and right.

· The front end of the drilling rig is equipped with an auxiliary rod unloading cylinder, which makes it easier to loosen the drill rod;

· Double sections oil pump, quick rotatry head lifting and descending speed.

· AMT manual automatic gear box, rotation speed range and torque can meet the requirements of both mud pump and compressor.

· Equipped with a foldable auxiliary tower, which can lift two 3 m / ari drill rods at a time.
