Recently，XCMG roadheaderEBZ260The equipment is sent to a tunnel project and put into use。Reliable operation of equipment during operation、The quality is excellent，Product performance and construction efficiency are well received by customers。

The working conditions of the tunnel constructed by XCMG TBM are complex.，Cross existence of various working conditions。The lithology of the lower section is fine sandstone.、Rich in quartz，Where is the Proctor hardness of rock? F8-F10Left and right，The construction is difficult.。

EBZHigh-strength wear-resistant steel plate is used for the loading mechanism of 260 roadheader、Double rocker tunnel mechanism、Hydraulic Motor、Clam plate tensioning structure of oil cylinder，The arrangement of cutting teeth is reasonable，Drilling、Strong rock breaking ability，Primarily for moderately hard rock formations on site、Construction of soft rock and relatively soft rock，Successfully completed the construction task of the project under complex working conditions.，Win praise from customers。

EBZThe 260 roadheader has LCD dynamic display of Chinese characters.、Self-diagnosis and memory function；Constant power is used、Pressure cut off、Load sensitive control、Longer component life；Adopt annular three-layer water curtain for dust removal，The whole machine is highly equipped、The stability is good、Safer and more reliable。

XugongEBZ260 Roadheader with high stability and safety，Breakthrough of 9 meters in a single day，Successfully broke the single-day tunneling record of the tunnel mine.。The equipment is in full attendance working state.，Monthly footage can reach 228 meters，Exceed the expected use effect，Compare the performance of the same type of products in the industry、Footage、The failure rate reflects the core competitive advantage.。

At present，XugongEBZSeries of coal mine roadheader has been formed light、Medium、Full range of heavy and hard rock products，It fully meets the construction requirements of coal mine in harsh conditions and different working conditions.，It provides efficient and safe mechanized construction equipment for coal mine roadway construction.，It greatly improves the technical level of domestic roadheader.。
