Roadheader picks

 Roadheader picks

Detailed introduction

A roadheader, also called a boom-type roadheader, road header machine, road header 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 travelling 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.


History

The first roadheader patent was applied for by Dr. Z. Ajtay in Hungary, in 1949.[1] It was invented as a remote operated priapic miner for exploitation of small seam, close walled deposits, typically in wet conditions.


Types

Cutting Heads:


Longitudinal - rotates parallel to the cutter boom axis

Transverse - rotates perpendicular to boom axis


Picks are important spare parts used for coal shearers and road headers. There are medium duty picks, heavy duty picks and super heavy duty picks for each type, based on the hardness coal seam or rock seam, as well as the power of equipments.

Owned world leading welding and heat treatment assembly line, we achieve the automation of welding and heat treatment during the process of picks production. The production process is controlled by full closed loop program, while each technical parameter strictly managed by computer. We guarantee to supply the best quality products to our clients.
