Roadheaders are an economical alternative to ‘drill and fire’ techniques, for excavation of soft rocks and when shield mounted, are adaptable to a wide range of spoils.

Ranging in sizes from 1500 mm (1780 mm o.dia) and upward for man entry operation.

Muck is removed by hydraulically driven belt conveyor and steered by hydraulic rams.
