ZF18000/21/38D four pillar support shield type hydraulic support for top coal caving
Technical Parameter
Applicable scope
Suitable for high-yield, efficient and intelligent fully mechanized mining face in thick coal seam, especially suitable for fully mechanized mining face in thin bedrock and thick coal seam.
Structural characteristics
1. The support strength reaches 1.82MPa or above, with strong support ability, impact resistance, and high stability, which can adapt to the geological characteristics of thin bedrock and thick coal seams, truly achieving “support and movement” in the working face;
2. Equipped with a high flow rate fast supply and return liquid system, the bracket action cycle time is short; Adopting a 1000L+500L high flow dual safety valve structure, it has strong impact resistance performance;
3. Equipped with electro-hydraulic control system, automatic control of group program can be realized, including automatic frame shifting, sliding, spray, etc;
4. The front and rear double link mechanism has good stability, high reliability, and strong anti torsion ability of the bracket;
5. Safety protection technologies for high mining height, anti leakage and coal dust prevention;
6. Green and environmentally friendly technology for emulsion recovery and reuse.
