Product Description

 HC726 Crawler Open-air Down-to-hole Drilling Rig

Product Description
HC726 crawler down-the-hole drilling rig is a model between light down-the-hole drilling rigs and large-scale down-the-hole drilling rigs. The drilling rig is hydraulically controlled for walking, propulsion, rotation, and positioning, and is equipped with a medium-pressure mobile screw rod. Air compressors and medium and high pressure down-the-hole impactors have high performance, affordable prices and low cost of use.
 

Product Features

Orbital motor gyrator
The gyrator with orbital motor and planetary gear has the characteristics of large slewing torque, high efficiency and durability.

Console
The multi-way valve adopts a single-layer combination method, with reasonable location and simple and convenient operation.

Drill boom
The drill boom has a novel structure and is easy to adjust, which greatly increases the drilling range and is suitable for drilling low-level horizontal holes.

Engine
Yuchai 40Kw four-cylinder diesel engine is used, elastic coupling transmission, stable and reliable, equipped with pre-filter, oil bath air filter and air filter for three-stage filtration, and equipped with auxiliary water tank (with antifreeze inside), greatly Improving the adaptability of the diesel engine to the environment.

Filtering system
The use of pre-filter, oil-bath air filter and air filter for three-stage filtration provides a guarantee for the diesel engine to work in a high-dust environment.

Travel motor track frame
It adopts engineering travel motor, which has strong climbing ability and low failure rate.
