FRP single hydraulic prop is also called light hydraulic prop. It is named because its cylinder is made of glass fiber reinforced plastic, and because it weighs less than ordinary steel props, it is also called light hydraulic prop. FRP single hydraulic prop are used in conjunction with π-beams or hinged roof beams to provide temporary support in coal mine roadways.
The glass fiber reinforced plastic single hydraulic prop uses emulsion or hydrostatic water as the working medium. Due to the anti-corrosion process adopted by key components (living column, cylinder, base, return spring, etc.), it has certain acid and alkali resistance, which is suitable for different working environment.
FRP single hydraulic prop features:
The glass fiber reinforced plastic single hydraulic prop is a constant resistance type prop for external liquid supply, which is manufactured by using special non-metallic materials. The glass fiber reinforced plastic prop has the characteristics of light weight, corrosion resistance and easy operation. The weight is only about 40% of the steel prop with the same height, which can greatly reduce the labor intensity of the operator and improve the work efficiency. FRP single hydraulic prop use emulsion or hydrostatic water as the working medium. Because key components (living columns, cylinders, bases, return springs, etc.) use anti-corrosion technology, they have certain resistance to acids and alkalis and are suitable for different working environments.
