Siton DD4-2b is a double-boom face drilling rig specifically designed for mining and tunneling applications with coverage area from 4.5×4.5m to 8×6.8m. This underground drilling jumbo features two independent, fully hydraulic drilling systems that can operate simultaneously without interference. Witha high-power rock drill, the two-boom jumbo rig delivers a drilling speed penertration rate of 2.5 m per minute,and offer strong adaptability and high efficiency in various underground environments.

Features and Benefits

1. Safety First

Given the inherent risks associated with drilling operations, such as falling rocks, equipment rollover, it is crucial to ensure the safety of operators. Siton addresses these concerns by equipping our development drilling rigs with canopy certified for FOPS (Falling Object Protective Structure) and ROPS (Roll Over Protective Structure), providing robust protection for operators.

2. Powerful Rock Drills

With high pressure and low flow hydraulic system. The hydraulic rock drill delivers high penetration rates in hard rock (< F17) and low drilling steel consumption. With the classic double damping design, the service life is long and the running cost is low. 18/20kw rock drills are standard, and higher power 22/25kw rock drills are optional.

3. Coordinated Operation

The double-boom configuration is equipped with two separately controlled,fully hydraulic rock drilling systems. Each boom can operate independently on different sections of the drift without interference, enabling simultaneous drilling tasks. This parallel operation significantly improves work efficiency, reduces idle time, and enhances overall project progress in multi-task working environments.

4. Extension Boom With a Fully Hydraulic Parallel Holding System

The dual-triangle hydraulic parallelism drill boom delivers extended reach and a broader working range. With swing-boom support, the feed assembly enhances visibility and positioning. The 1500mm telescopic extension increases coverage, enabling full-face drilling in one stop.

5. Chassis

The equipped diesel engine complies with the ChinaIII emission standards. Equipped with multiple wet braking discs on four wheels and dual-circuit braking system, the chassis ensures safe and reliable tramming and parking. The central articulated design, hydraulic power steering, four-wheel drive, and±40°steering angle provide excellent mobility in narrow drifts.

6. Hydraulic Control System

The automatic rod anti-jamming and return system can protect rock drill and drill tools. Additionally, a built-in collision protection valve safeguards the rock drill and drilling tools from damage due to unexpected resistance or misalignment. This intelligent protection setup not only reduces maintenance downtime but also extends the lifespan of key components, ensuring safer and more reliable operation in demanding underground conditions.
