HD-C20 Mechanical Drive Crawler Drilling Rig 

1, Drilling rig Characteristic:

With different of combination methods, the rig has the function of air drilling, air hammer drilling, auger drilling, mud drilling for mineral exploration prospecting, it is suitable for marsh, beach, snow, grasslands, snow, forests, swamps, the seasonal farmland etc. The drilling depth is deep to 20meters.

It employs hydraulic driven, simple to use and easy to maintain. The machine selects the mature products of well-known specialized company of the world, for example: Kubota, HAWE, STAUFF, Eaton and so on, guarantee the rig reliable.

The rubber crawler chassis is driven by hydraulic motor via gear box, it has high speed, low ground pressure, strong adaptability to ground surface. The hydraulic operation of chassis walking or rig can use the remote control or manual. It is meet the demand of vegetation protection and green construction.

The rig is powered by 14Hp gasoline engine. it is the ideal power in field reducing fuel consumption.

Slide-way type mast is made of rectangular section material and slide plate by welded together.

The rig equipped a new type power swivel, which separate the fluid circulation channel and the bearing shell, and which can reduce the probability of bearing damage.

Drill tools hoisting/pull down through roller chain system driven by a hydraulic motor. System adopt 12A type sleeve roller chain to ensure the lifting power to meet the 1500 kg at the same time safely and reliable.

Drill rig equipped with the weight balance system components to ensure the rig working in the smooth movements, reliable and safe under load. The system sets the hydraulic balance valve and pressure relief valve.
