　　Characteristics of DW18-300/110X single hydraulic prop

　　The DW18-300/110X single hydraulic support column has no load-bearing welds and adopts the principle of plunger suspension technology, which allows the hydraulic suspension force to directly act on the top cover through the inner cavity of the support column, sharing about four fifths of the working resistance of the support column. The axial force of the support column is only one-fifth of the working resistance, improving the stability and safety of the support column, and greatly increasing the support height and bearing capacity of the support column; At present, both domestic and foreign pillar products are using piston technology principles, which cannot fully utilize the hydraulic suspension force to share the working resistance of the pillar, causing the pillar to bear all the working resistance, resulting in frequent bending and damage to the pillar, leading to roof collapse accidents.
