Product Overview

The AT-2000L Raise Boring Machine was developed to meet the evolving requirements of modern underground mining operations, building on the proven advantages of the company's existing mobile raise boring technology. Optimized rock-drilling parameters and an integrated system design enable a compact, low-profile machine configuration.

The travel system incorporates an articulated chassis with a central steering joint, improving maneuverability compared with a conventional rigid-frame configuration. Combined with advanced remote-control technology, the AT-2000L offers a compact turning radius, excellent maneuverability, and enhanced operational safety, making it well suited to confined underground mining environments.

Key Features

High drilling torque together with stepless speed adjustment offers flexible parameter tuning for diverse ground conditions.

5.Compact Overall Layout

Compact dimensions simplify transport, installation and relocation inside narrow underground work zones.

6.Superior Drilling Precision

High borehole accuracy ensures consistent and reliable raise‑boring construction.

7.Good Site Adaptability & Agility

Balanced overall performance enables seamless transition between different underground work faces.

8.Heavy‑Duty Reliable Performance

High impact resistance delivers dependable operation under harsh underground working conditions.

9.Capability for Hard‑Rock & Large‑Diameter Boreholes

Capable of raise boring in hard rock formations and for large‑diameter shaft requirements.

10.Modular Construction

Modular‑based design simplifies maintenance, inspection and spare‑part replacement.

11.Advanced Wireless Remote Operation

Wireless remote control enables safe long‑distance manipulation, bringing high flexibility for machine positioning and on‑site work.

Automatic Drill‑Rod Handling System

Fitted with an automatic drill‑rod manipulator arm, the AT‑2000L eliminates the requirement for an auxiliary crane. It picks drill rods directly from ground and accurately places them at the rod loading‑unloading station. Manual labour is greatly reduced, on‑site safety is enhanced, operator workload is decreased, and drill‑rod handling procedures are highly streamlined.

Advanced Hydraulic System

The integrated hydraulic circuit is optimally laid out for higher system stability. The load‑sensing proportional control reduces useless power consumption and heat build‑up, improving energy efficiency and system response. Premium hydraulic parts together with imported sealing elements minimise leakage risks and ensure long‑term dependable service.

Articulated Travel Chassis

The centrally‑jointed articulated chassis delivers superior manoeuvrability within narrow underground tunnels. Compact overall size and flexible steering behaviour support easy relocation and operation in space‑constrained sites.

Load‑Sensing Proportional Travel Control

Load‑sensing proportional control provides smooth stepless speed adjustment and mitigates inertial shock upon start and stop. Fine movement control improves machine agility, operator comfort and operational safety in confined underground surroundings.
