It can be operated in all terrains and complex working conditions, and the meteorological weathered rock, strong weathered rock, cobblestone, backfill stone, etc. can be taken by one machine
Sany SR75 excavator is used as the platform and converted into a small rotary drilling rig. It uses an imported Isuzu engine, with a drilling depth of 15m, aperture diameter of 350-1500mm, and an overall weight of 12t. It is compact and suitable for transportation and transition, and is especially suitable for construction in low, narrow and small spaces.
Power system
It is equipped with an Isuzu 4JG3X engine with a rated power of 55kW and more power margin. It adopts high-pressure common rail technology and reduces fuel consumption at the rated point.
Hydraulic system
Equipped with a load-sensitive system, it has higher operating efficiency, better control performance and superior drilling performance.
The main valve diameter is large, the pressure loss is reduced, the valve body oil passage is optimized, the hydraulic force is reduced, and the overall operating energy efficiency is improved.
DPD+EGR technology line
Part of the exhaust gas circulates into the intake system, mixes with fresh air and is burned to inhibit the generation of Nox. The EGR is upgraded from a tubular type to a laminated type for faster cooling;
Structural parts optimization-durable
Upgrading of luffing mechanism, mast and drill pipe: Using national standard thickened plates, the wear resistance is enhanced, the mechanism is optimized, and the service life is effectively improved.
Reinforced lower frame: The reinforced one-piece welded X-shaped lower frame has more advantages in safety and reliability than the H-shaped one, and its service life is greatly improved.
Upgraded cab-new experience
Interior upgrade: The interior styling is newly designed, and the water cup position is adjusted to in front of the right operating lever to reduce the air duct space on the right side. The multi-function panel, one-button start and throttle knob are combined into one, and it comes standard with a water cup holder, 12V power port and USB interface, making it more user-friendly.
7-inch smart touch screen: The screen integrates Bluetooth, USB, phone, radio and other functions. You can freely switch between multimedia audio source devices and view vehicle status information at any time.
Air-conditioning upgrade: Use automotive-grade air outlets to optimize the position of the air-conditioning outlets, which is more ergonomic and under constant temperature control from head to toe.
