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. 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.

CMM Series Mobile Bolter Technical features:1.Multiple independent drill arms operating in parallel for efficientroof and side wall support;2.Flexibly adjustable drill arm orientation to meet the diversifiedrequirements for drill arm numbers and spacing;3.Highly reliable crawler traveling mechanism with good adaptabilityto the roadway floor;4. Cable winding device for automatic cable retracting and layingwhen the truck is moving;5. Standard dry drilling dust collection device to purify the workingface environment and ensure personnel health.

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.

Technical features1.There are multiple drill arms for independent operation in parallel, with highsupport efficiency;2.The drill arm can be adjusted flexibly, with a large range of adjustments and awide range of applications;3. The bolt drill rig can be equipped with electro-hydraulic control valve group torealize the automation of the anchor drilling process, reducing the laborintensity of operators.
