High-Power Core Drilling Machine Jr350 with Superior Lifting Force

Product Description

Detailed Photos

Our company not only produces and sells new machines, but also has a vast network of premium second-hand drilling rigs and air compressors. The major advantages of second-hand machinery include affordability, excellent quality, and superior cost-effectiveness.

This machine is equipped with an excavator track chassis, offering exceptional off-road performance. It can also be mounted on trucks, enhancing its maneuverability and versatility in various terrains.

Upon receiving these units, our first step is to meticulously prepare them. We replace all non-functional valves, oil, and gas pipes, followed by applying an anti-rust paint coating on the casing to ensure durability and longevity.

This machine features a high-torque hydraulic motor power head and branded diesel engine. The hydraulic control system incorporates a large diameter hydraulic cylinder. The branded diesel engine comes with a two-stage air filtration system for enhanced protection and can be directly cleaned using air from the compressor.

The innovative convex block design and centralized control operating system simplify maintenance and significantly ease the operation of the machine.

This machine can be equipped with either a mud pump or an air compressor drive, making it suitable for both water and steam applications. It is adaptable to various working environments..

While the quality of our second-hand machines is nearly on par with new ones, the cost is significantly lower, providing exceptional value for your investment.
