"A roadheader, also called a boom-type roadheader, roadheader machine, roadheader or just header machine, is a piece of excavating equipment consisting of a boom-mounted cutting head, a loading device usually involving a conveyor, and a crawler traveling track to move the entire machine forward into the rock face. The cutting head can be a general purpose rotating drum mounted in line or perpendicular to the boom, or can be special function heads such as jack-hammer like spikes, compression fracture micro-wheel heads like those on larger tunnel boring machines, a slicer head like a gigantic chain saw for dicing up rock, or simple jaw-like buckets of traditional excavators."


Mining Machines - Roadheader

Webster Machines offers a range of roadheader machines from several manufacturers and will advise of the best suited machine for a project. We have supplied roadheader machines worldwide manufactured by Wirth, Voest Alpine, Eickhoff, Dosco & Long Airdox.


Roof and Rib Bolting

In the event of the machine cutting where the heading requires a bolting pattern to roof and rib, we can supply the roadheader with a purpose designed bolting rig That will enable the machine to cut, clear, and bolt both rib and roof in a cyclic operation. In the event of unstable conditions or faulted areas, we can set the bolters to work as close as 900 mm to the heading face. In areas where only faulted areas exist, we can provide a working platform fitted with bolting pods that enable the operator to quickly swing the platform in to position (fixed to the cutting boom), and by way of simple leg drills can bolt a faulted area in a very fast, and economical way.
