Crawler Chassis Gas 300m Pneumatic Borewell Machine
Pneumatic Borewell Machine Brief Introduction
The Pneumatic Borewell Machine is a highly efficient, multi-functional drilling equipment primarily designed for drilling wells, agricultural irrigation wells, geothermal air conditioning holes, and other well holes. It is especially suitable for water intake projects in mountainous and rocky strata. The efficiency is more than ten times higher than traditional rotary drilling rigs, creating considerable economic benefits for users. This machine effectively solves drilling difficulties in soil and air DTH operations, addresses construction problems in hard rock layers and gravel layers with rotary drills, and works efficiently in various geological structures to achieve the perfect combination of water and pneumatic drilling.

- Primarily uses mechanical transmission with hydraulic transmission for auxiliary functions, effectively utilizing power and reducing overall power loss for lower drilling costs
- Features multiple positive speed series with a 14-500 r/min speed range and output torque of 13428-250 N.m
- Includes 2-speed reversal for easy accident handling
- Utilizes mechanical power head with long stroke and speed multiplication system (3800mm stroke) to improve drilling efficiency and reduce drill blocking and burning accidents
- Eliminates double fuel pump usage - drilling with single pump, hoisting and lowering with double pump confluence to reduce power loss and shorten auxiliary time
- Incorporates advanced structure with reasonable layout for easy maintenance and repair
- Uses crawler chassis with 1.5m leg cylinder stroke for automatic loading and easy transport
- Reserves functional interfaces in hydraulic system for extension according to different user technical requirements
Mainly suitable for drilling wells, agricultural irrigation wells, geothermal air conditioning holes, and other well holes. Particularly effective for water intake projects in mountainous and rocky strata.
