DWX type suspension hydraulic acrow props is a kind of (external injection) single supporting equipment. This prop series has 15 specifications, which are suitable for coal seams with a height of 0.63-4.5 meters. Generally, each layer has a gentle slope with an inclination angle of less than 25 degrees. If certain safety measures are taken for the working face, the scope of application can be expanded to the working face with an inclination of 25 degrees to 45 degrees. Today, I introduced to you the principle of the anti-eccentric load capacity and stability of the DWX suspension single hydraulic prop.
DWX type suspension hydraulic prop adopts the principle of plunger suspension technology, so that the hydraulic suspension force directly acts on the top cover through the inner cavity of the pillar movable column, so that the hydraulic suspension force shares about four-fifths of the working resistance of the pillar, making the The axial force of the column is only one-fifth of the working resistance, which improves the stability and safety of the column, and also greatly improves the support height and bearing capacity of the column;
However, the domestic and foreign hydraulic acrow props products currently in use all adopt the principle of piston technology, which cannot make full use of the hydraulic suspension force to share the working resistance of the column, so that the column bears all the working resistance, and the column is often bent and caused The single hydraulic prop was damaged, causing a roof fall accident.
I don’t know if it’s useful to you. If you want to know more about the hydraulic acrow props, please pay attention to the future reports on our website. Hydraulic prop manufacturers, monolithic hydraulic props, single hydraulic prop and Shandong Zhongmei Manufacturing Ltd. We will provide more comprehensive knowledge of suspension hydraulic prop products for friends everywhere.
