Products Description

To put it simply, this dual-boom tunnel drilling rig is essentially two drilling units packed into a single vehicle chassis. It extends two booms simultaneously-allowing it to drill two holes from a single stationary position-making it ideally suited for tasks such as tunnel support, pipe roofing, and anchor bolting.

Let's start with its operational reach. It covers a vertical height range of 8 to 13 meters, features a sliding carriage system, and can even be customized to meet specific site requirements. The engine is a turbocharged Yuchai unit; it runs on diesel but can also be plugged in for electric operation, offering true dual-power versatility. With a 55 kW electric motor and a hydraulic pressure of 20 MPa, it packs plenty of power.

Its true strength, however, lies in its booms. They offer a vertical tilt of 90 degrees upward, a full 360-degree horizontal rotation, and an operational angle range of ±30 degrees. What does this mean in practice? It can drill horizontal, inclined, and vertical holes-all without the need to switch equipment. The sliding carriage provides a 4-meter feed stroke in a single pass, accommodating drilling diameters ranging from 32 to 76 millimeters. The feed pressure is hydraulically controlled rather than relying on brute mechanical force, ensuring stable and precise drilling.

The power head utilizes the PD-200L model, though you also have the option to install a hydraulic rock drill if preferred. The oil pump features a K3V90-45unit, while the cooling system is equipped with a Jintai FLJ-136 radiator-ensuring that even after a full day of continuous operation in high-temperature tunnel environments, the machine won't overheat.

Now, let's look at the chassis. It features a 4-wheel drive system with a top speed of 18km/h and utilizes a fail-safe air-brake system. The front and rear axles are model WL96-H2A-Q2A, fitted with 880/295-20/7.5 tires, allowing the rig to traverse gravel, muddy terrain, and steep ramps with ease. It is equipped with four hydraulic outriggers-the front two of which can extend laterally-firmly anchoring the machine to the ground during operation to ensure a rock-steady, vibration-free platform.

It offers a dual-operator control mode: two operators can work simultaneously-each controlling a separate boom-eliminating bottlenecks and wait times. The fully enclosed bodywork, complete with an engine cover, enhances both safety and dust protection.

Who is this machine for? It is ideal for tunnel support, anchor bolt installation, blast-hole drilling, and pipe roofing operations. In short: if you are tired of having to reposition your vehicle every time you need to drill a single hole, this dual-boom rig will cut your unnecessary maneuvering time-and effort-by half.

This isn't a delicate precision instrument meant for a laboratory; it is a rugged, "dual-armed workhorse" built to the tunnel environment. If you think drilling is too slow, this is exactly what you need.
