Compared with the currently used DW type prop series hydraulic acrow props, DWX type suspension hydraulic prop series products have the following characteristics:
1. Adopting the principle of plunger suspension hydraulic prop technology, the suspension force reaches four-fifths of the working resistance, and the force on the column is only one-fifth. Greatly improve the stability and safety of the hydraulic acrow props.
2. There are no longer arc welding seams that are difficult to guarantee on the column, which improves the strength and reliability of the column, avoids hidden dangers such as roof fall caused by the fracture of the welding seam, and ensures the safety of the staff.
3. According to different single hydraulic prop specifications, the weight of the entire column is reduced by 15-20%, and it is very convenient to move, transport and use. Its weight is the same as that of aluminum alloy pillars, but the working resistance and working stroke are higher than aluminum alloy single hydraulic prop.
4. Large working stroke expands the scope of application. Especially for working faces with large roof sinking, the DWX-type Dahang hydraulic acrow props can still meet the large constant increase in resistance and decrease distance, which not only facilitates the return of the pillar, but also improves the recovery rate of the pillar and reduces the pillar consumption.
5. The original DW-type single hydraulic prop caused the false top of the pillars due to leakage, and even caused the pillars to automatically fall down and hurt people. In order to avoid the virtual roof, an instrument must be used to detect the internal leakage of the pillar. The DWX series suspension pillars can be visually inspected by the naked eye. Once the pillars leak, they can be filled or replaced at any time, eliminating the need for timed and tedious inspection workloads and the staff should not worry about work. Improve the safety and reliability of pillar work.
The above are the structural principles and advantages of the suspension hydraulic prop. I don’t know if the knowledge provided by the editor is useful to you, please pay more attention to our official website, I believe you will have the product knowledge you need.
