“Drill when in doubt, frst drill and then tunnel”. EBZ220T cantilever road  header is designed for the unknown geological conditions or the existence of dangerous sources (water, gas, etc.) in the mining process of coal mines. lt is a kind of all-in-one digging machine that integrates the functions of tunneling and advanced drilling construction. The drilling machine carried bythis machine can effectively complete the advanced drilling constructiorwithin a certain range of the full mechanized mining face.Technical features:1.

EBZ220B cantilever road header is mainly used for the tunneling of the fully mechanized coal mine face, and mainly suitable for the construction of thin seam small section coal and half-coal rock roadway tunneling. The whole machine has the following characteristics:Technical features:1. The height of the whole machine is low, which can adapt to thin seam half-coalrock roadway tunneling. 2. lt adopts two-speed cutting, with large torque at low speed, fast speed, andhigh effciency of cutting; lt has good cutting stability and strong cutting ability.3.

Technical features1.This machine adopts the constant power two-speed cutting technology for thefrst time, can be easily switched between high and low speeds and has a highcutting efficiency;2. The hydraulic system adopts constant power variable pump with load sensitivitycontrol and proportional multi-way directional valve and other newcomponents, greatly improving the efficiency of the hydraulic system;3. For the first time, the working pressure of China's road headers has beenincreased from 16 MPa to 23 MPa, and this machine can operate reliably.

Technical features1. It can make full use of its own weight in the cutting process, with good cuttingstability and strong cutting ability;2.According to the condition of total rock tunneling, the wear-resisting propertyof the cutting head, cutting pick and transport mechanism is greatly improved;3. Important structural parts such as rack and rotary trunnion, are welded withhigh-strength steel plates, with large bearing capacity and high safety factor;4.

Technical features:1. The cutting motor is a double speed motor. The average single tool force at low speed is 1.5 times that at high speed, and the cutting effciency is high.2. The centralized lubricating system is used to centrally lubricate the entire rotary table and the bearings of key parts.3. The compact design is adopted, the position of the center of gravity is low,and the stability of the whole machine is good.4. The tensioning of scraper conveyor chain and track chain is achieved by means of a hydraulic cylinder for easy maintenance.5.
