The single hydraulic prop for mining uses a hydraulic pressure to generate working resistance and achieve a single adjustable prop for lifting and unloading.
The situation and hazards of the expansion of a single hydraulic prop in the production process are briefly introduced. The technical conditions such as theoretical calculation, laboratory experiments
Single hydraulic prop The metal prop is a micro-increased friction metal prop, which is used to support the roof of the coal mining face. Metal hydraulic props can also be used on working surfaces tha
Many customers do not know how to choose the right hydraulic prop. Based on our many years of industry experience, we have summarized the following points for how to choose the suitable hydraulic prop
The initial support force refers to the active support force provided by the pillar to the roof through pumping pressure. A larger initial support force can make the pillar reach the working resistanc
The anti-skid function of the single machine (rack) alone can not solve this stage well. The acrow prop must also combine the adjacent multiple pairs of brackets into a single anti-skid, non-slip grou
