Presenting the MT520 Tunneling Roadheader

Sandvik presents the MT520 Tunneling Roadheader – a novel construction roadheader in the 100-ton class

The Sandvik MT520 is a novel construction roadheader in the 100-ton class. The machine concept is based on easily exchangeable optional modules, enabling the MT 520 basic machine to be adapted to a wide variety of applications. The machine’s eight-meter cutting height module means that it is highly suitable for large road tunnels.

The main focus in the development of this new machine was increased productivity and safety. For example, the driver enjoys a fully air-conditioned cabin with ergonomic controls, mounted on shock-absorbers. Active stabilization of the machine during cutting minimizes vibrations.

Easily exchangeable modules form the basis for cost-effective tunneling in cutting conditions up to a compressive strength of approximately 100 MPa (UCS), where the ICUTROCTM hard-rock cutting capability is not required.
For maximum cutting performance in soft ground, the cutter head can be exchanged within less than a shift. The full cutter motor power of 315 kW is available both on the transverse and on the in-line cutter head model.
An integrated dust-extraction system ensures a healthy work environment for the tunneling team.

Main dimensions
Total weight 110 – 115 tons
Cutter head: 315 KW
Cutting height, max. 7.1 m (8.0 m with extension module)
Cutting width, max. 10.3 m (10.8 m with extension module)

Options
The optional modules available include: Eight-meter cutting height module, In-line cutter head, easily interchanged with a standard transverse cutter head, On-board diesel power pack for quick and easy relocation, Slewing belt conveyor for truck loading, Water hose and cable reel, High-pressure water spray ring system for efficient dust suppression and pick cooling, Automatic fire suppression, Directional control system, Profile Control and visualization.
