Long-life Mining Hose Assembly Solution

  • Inner rubber layer: Nitrile/chloroprene synthetic rubber, suitable for biodegradable hydraulic fluids.
  • Reinforcing layer: One layer of steel wire braid (1/2" – 3/4"), impulse ≥ 300,000 cycles; Four layers of steel wire winding (1" – 2"), impulse ≥ 1,000,000 cycles.
  • Outer rubber layer: Standard tube: Peel-free, wear-resistant, weather-resistant synthetic rubber; Wear-resistant tube: Peel-free, high wear-resistant, weather-resistant synthetic rubber; Ultra-wear-resistant tube: Peel-free, ultra-wear-resistant, weather-resistant UHMWPE.
  • Temperature range: -40℃ to +121℃ (-40℉ to +250℉).
  • Standards: Exceeds ISO18752-AC/CC standards.
  • Bending radius: 41% reduced compared to ISO18752 standards; 47% reduced compared to SAE standards; pressure exceeds SAE standards by 60%.
  • low bending

    The bending radius is 34% lower than the ISO 18752 Class C standard.

  • High pressure

    Pressure 25% higher than SAE/DIN standard

  • Long lifespan

    The number of impulses in the hoses all exceeded 1 million.

  • Zero leakage

    When used with Letone Technology's self-developed hose connectors and hydrogenated nitrile butadiene seals, the service life can exceed 5 years (with a two-year warranty).

  • Good service

    Our pipeline system integration solutions strive to provide five "saving" services: saving time, effort, trouble, money, and worry.

  • Harsh environment

    Harsh environment

    The on-site installation environment for fully mechanized coal mining equipment is poor. Fully mechanized coal mining equipment, represented by hydraulic supports, is mainly used in underground coal mining operations. Due to the confined space and complex environment of underground coal mining operations, the installation and commissioning of fully mechanized coal mining equipment are extremely difficult.
  • Harsh Environment 2

    Harsh Environment 2

    The harsh environment and heavy loads of coal mining equipment put a strong impact on the hydraulic system, making it prone to failure and thus affecting safe production in the coal mine.
  • Harsh Environment 3

    Harsh Environment 3

    The complex mining environment and changing external factors in coal mines easily lead to wear and tear on hydraulic pipelines of fully mechanized mining equipment such as hydraulic supports. This can cause the outer rubber of the hoses to rupture, the steel wires in the hoses to rust and break, and the hoses to burst, resulting in abnormal operation of hydraulic system components and frequent malfunctions. Replacement is frequent and requires replacement with...
  • Harsh Environment 4

    Harsh Environment 4

    Hose assemblies made of carbon steel, used as hydraulic system components in fully mechanized mining equipment, are constantly exposed to chemical waste and humid environments, making their joints highly susceptible to corrosion. Leaks and spills in production equipment and pipelines caused by corrosion can lead to serious problems.
