Support shield hydraulic support ZZ20000/28/62/D

Product Feature

APPLICATION

1. Realize the purpose of mining full height at one time with thick coal seam, super large working resistance and super large expansion ratio.

2. The bracket adapts to the top plate with strong pressure, and the top plate control effect is remarkable.

3. The support adopts an electro-hydraulic control system, which can realize automatic follow-up, sequential transfer and remote control, and can realize the needs of intelligent and automatic coal mining at the working face.

ADVANTAGE

1.1.75m four-column support shielded hydraulic support with super large working resistance and super large expansion ratio, working resistance can reach 20000-24000kN;

2. The support can use a working surface inclination of about 15°;

3. Both the front and rear columns of the bracket are high-reliability double telescopic columns with a cylinder diameter of φ400mm, and the fixed form adopts an external pressure plate structure;

4. The bracket adopts a steep shield beam and a short four-bar structure, which increases the back angle of the bracket, reduces the area of the back gangue, and improves the safety, reliability and adaptability of the bracket.
