EBZ55 Tunneling Machine, Roadheader,tunnel boring machine,Construction machines
Introduction
EBZ55 is a kind of cantilever tunneling machine which is integrating cutting, loading and traveling function, applicable to the coal or semi-coal tunnel.

Main features
1.Compact structure, easy to operate. With external spray device to reduce the dust during cutting

2.Small conical diameter cutter, bigger force on the simple teeth. The layout of the teeth is reasonable, more easily to break rock and get through the fault, with less vibration and better stability.


3.Swiveling and lifting or lowering of the cutter can be achieved simultaneously, curve cutting can be achieved

4.Hydraulic parts all imported

5.Adoption of unique separate system to reduce accident, improving in loading capacity

6.Optional hydraulic anchor drill drive device, driving one or two machine to operate

Shield tunneling machine is a tunnel boring machine using shield tunneling method. Shield construction method is tunneling machine in tunneling at the same time to build (laying) tunnel "shield" (refers to the supporting segment), it is different from the open construction
method. Internationally, generalized shield tunneling machine can also be used in rock formation, but different from the open (non-shield tunneling machine) tunnel boring machine. But in our country, the tunnel tunneling machine used for soft soil layer is habitually called the narrow sense shield machine, will be used for the rock formation to be called the (narrow sense) TBM. According to the working principle, the shield machine is generally divided into hand digging shield, extrusion shield, semi-mechanical shield (local pressure, global pressure), mechanical shield (open-chest cutting shield, pneumatic shield, mud and water pressure shield, earth pressure balance shield, mixed
shield, special-type shield).
