The main feature of mining equipment hydraulic support is the core technology of sugar making equipment

The single hydraulic prop of the sugar-making equipment utilizes the liquid pressure to generate working resistance and realizes a single retractable prop for lifting and unloading.

1. Large working schedule and low safety management cost

Each specification can replace 2-4 specifications of traditional piston type single pillars, which reduces the frequency of changing different types of single pillars due to the change in the mining face height and the movement of the roof and floor of the roadway, which reduces the labor intensity of workers. And the extra spare number of pillars.

2. High support strength, good safety and stability

The pillar has no bearing welds, and the pillar adopts the suspension technology principle. The suspension force generated by the high-pressure liquid directly acts on the end of the top cover, reaching four-fifths of the working resistance, and the force of the pillar is only one-fifth, which greatly improves the pillar. Support stability and partial load capacity.

3. Leakage is easy to find, safe and reliable

Due to the structural improvement, the prop virtual roof and top off caused by internal leakage are avoided. Once the prop leaks, it can be directly detected by the naked eye in the underground site, and the prop can be replaced at any time; the principle of seal compensation and seal tensioning technology is adopted , The greater the pressure on the top plate, the tighter the sealing surface fits, the less likely it is to leak.

4. Long service life, easy operation and maintenance

The overall structure is simple and the service life is long; it is easy to operate and easy to maintain, which can greatly reduce the well lifting and maintenance rate of the pillar.
