Roadheader

Introduction

Introduction of Roadheader

Roadheader

EBZ Series Roadhader, also known as boring machine, is a boom-type road header machine which widely used for tunneling and coal mining. Roadheader mainly for coal mining fully mechanized mining and high grade general mining work, quasi roadway excavation services machinery and equipment. The utility model is mainly suitable for the drivage of the semi coal rock roadway and the rock lane, and is also suitable for the tunneling of other mines and engineering tunnels with similar conditions.

Five Highlights

Five Highlights of Roadheader

Strong shock resistance The walking drive system adopts internationally famous brand, which effectively increases the traction and climbing ability of the equipment.The walking track adopts the military technology and the integral forging track plate. The utility model has the advantages of high strength and strong shock resistance.

Strong power Efficient The cutting head is driven by motors and has high overload capacity.The cutting head has the advantages of single tool force, reasonable arrangement of cutting teeth, and strong rock breaking and fault crossing ability.Cutting adopts famous brand and has strong rock breaking ability.

Advanced Electric & Water System

The electric system adopts advanced programmable logic controller (PLC), which is equipped with Chinese LCD screen. It has various functions of protection and display. Water system is equipped with backwashing filter, effectively filter foreign water impurities, to ensure smooth water system pipe water.

Five Highlights of Roadheader

Efficient Dust Removal Integrated dust removal system innovated in the industry: long-pressure short air ventilation curtain type dust removal system with a total dust removal efficiency of ≥97%. On-board mining-purpose dust-proof suction system: fundamentally solve the problem of harm to health of staff by construction dust and powder.

Good hydropower system A star wheel, driven by imported low speed high torque hydraulic motor direct connection. The hydraulic system adopts 220kw oil pump motor, variable system, load sensitive multiway valve and hydraulic control pilot valve. Lubrication system uses centralized lubrication, so that regular lubrication work more convenient and more reliable.
