MODEL DD2
Hydraulic Drill Jumbo
Advanced Performance • Extended Boom • Superior Versatility
Product Overview
The DD2 hydraulic drill jumbo is an upgraded model based on our standard design, featuring an extended boom structure. With its narrow body and telescopic boom, the machine is capable of working efficiently in both confined tunnels of 2.6–3 meters and larger mining chambers of 3–6 meters. This versatility makes it ideal for a wide range of underground mining applications.
Equipped with a high-performance 22kW Swedish rock drill, the DD2 delivers a drilling speed of 0.8–2m/min, ensuring reliable performance under various rock conditions. Its diesel engine, four-wheel drive system, and articulated chassis allow smooth operation and excellent maneuverability, even in narrow turns and complex tunnel layouts.
