Advantages of Suspension hydraulic prop structural design
Brief introduction：
First of all, you are welcome to browse our company's products, and allow me to explain to you the advantages of suspension hydraulic struts in terms of performance characteristics. First of all, our company has strict requirements for the production process and quality, and every pillar has been quality checked, so you can fully rely on our products.
Our Suspension hydraulic prop is designed to be self-aligning and adapt to roof changes to reduce eccentricity and stress concentrations.The hydraulic prop adopts a fixed design, and the top of the pillar is fixed, which cannot be self-aligned, and is prone to eccentric load and stress concentration.Therefore, from this point of view, our Suspension hydraulic prop has a higher safety factor, longer service life, and is more effective in facing emergencies that occur underground.Secondly, Suspension hydraulic prop is analyzed from the hydraulic system, Suspension hydraulic prop is equipped with a high-efficiency hydraulic system to provide rapid lifting and stable support, which greatly increases the efficiency of underground staff to build support equipment at the time, which can more effectively improve your mining speed, and at the same time, yo has a more stable support force and can more effectively ensure the safety of staff.The hydraulic system of hydraulic prop is relatively simple, and the operating speed and support stability are lower than that of Suspension hydraulic prop.
Finally, if you need to continue to know more about our products in more detail, then you can contact me, our company will have special technicians to answer for you according to your specific needs, if you need we will modify our products according to your specific needs, we will guarantee your mine safety.
After-sales service is solemnly promised：
Shandong Changmiaoxin Coal Mining Machinery Co., Ltd. attaches great importance to the after-sales service of products, under the premise of high-quality products, after-sales service is our company's first important commitment.The company has a professional after-sales service team, which region the products are sold to, which region has special after-sales service personnel, and in the sales area to establish offices, so as to help users select and design free of charge, train operators to learn theoretically, master the technical characteristics of the single pillar, and demonstrate ground operation.
