At present, the head of hydraulic prop with three-purpose valve is welded on the movable column at home and abroad. When the movable column rises, the operator must follow it. Especially for the higher working face, the single hydraulic prop operator is not convenient and safe;
The three-way valve of the suspension hydraulic prop is designed on the handle body, and the three-purpose valve does not rise with the movable column during liquid injection. It increases the working stroke of the prop, is easy to operate, safe and reliable, and is convenient for the management and use of underground site, and reduces the labor intensity of miners.
The birth of each product will have its own advantages, just like the floating hydraulic prop, which is to be safer and more convenient in work. China Coal Group production of single hydraulic prop, suspension hydraulic prop, hydraulic prop. Welcome to consult and discuss.
