KEY FEATURES
Designed for challenging underground conditions, the BullDrill Trackmounted Underground series delivers exceptional maneuverability and uninterrupted performance on any terrain with its crawler track system, high-torque spindle head, and robust structure.
01
High-End Electric Motor
Our underground drilling rigs are powered by ABB or SIEMENS electric motors, ensuring high performance and reliability. With power outputs ranging from 55 to 110 kW and speed up to 1480 rpm, they deliver efficient and consistent drilling capability.
02
Robust Hydraulic Pumps
Our underground drilling rigs feature four KAWASAKI hydraulic pumps in a tandem configuration, operating at 280 or 315 bar pressure. The system is cooled by a HYDAC water-cooling unit and an air-cooling system from PARKER or AKG.
03
Vigorous Rotary Head
Designed for maximum efficiency, the open-feed spindle rotary head reaches speeds up to 1200 rpm with torque ranging from 1020 to 2060 Nm. It is powered by PARKER or REXROTH hydromotors for smooth and powerful operation.
04
Easy Navigation With Double Reducers
Two hydraulically-controlled reducers are positioned at the bottom and at the boom-to-mas connection. This setup allows for effortless and fast 360° drilling in underground operations.
05
Wireline System With Automatic Winding Feature
The automatic winding wireline system reduces manual handling risks and ensures consistent tension control. It prevents cable snapping, minimizes wear and tear, and improves core retrieval speed and accuracy.
06
High-Strength Rod Holder
The gas-pressure-operated rod holder secures rods using TC insert jaws, providing an axial holding force of 70 to 130 kN, ensuring firm and reliable grip.
07
User-Friendly Control Panel
An intuitive and easy-to-use control panel allows precise control over drilling operations while maintaining advanced functionality.
08
Highly Efficient Diesel Engine for Tramming
A PERKINS 4-cylinder diesel engine generating 50 hp powers the tramming system, ensuring reliable movement and positioning in underground environments.
09
High-Quality Crawler System
Manufactured by USTEC, the ex-proof crawler system delivers excellent traction and stability, reaching speeds of up to 3.4 km/h for smooth maneuverability.
10
Integrated Flush Pump
The triplex mud pump,attached onto the rig chassis, provides a flow rate of 90 - 140l/min at 60 - 70 bar pressure, ensuring efficient flushing performance.
11
Safety Cage for Sound Operations
A mechanically or hydraulically controlled safety cage enhances operator safety during drilling operations.
12
Dual Emergency Stop System
An emergency stop button is located on the control panel, with an additional wire emergency stop positioned on the mast for immediate shutdown in critical situations.

The technical data presented in this brochure is provided as a general and theoretical reference only. The drilling capacities of the rigs are calculated based on drilling in a fully vertical (90°) position, considering the available pull/feed force, the weight of the drill string in the borehole, and the average weight on the bit. Due to variable factors such as the geological structure of the drilled rock formation and operator use, BARKOM does not guarantee that these capacities can be achieved under all working conditions. The dimensions and measurements indicated in the tables and drawings may be subject to minor changes.
