In complex working conditions such as mining, infrastructure construction, road building, and engineering hoisting, the stable output of construction machinery never depends solely on the core power engine, but also on a reliable hose delivery system.

Large-diameter high-pressure hose: the core power hose of engineering machinery

High-pressure hoses are core components of hydraulic systems in construction machinery, primarily responsible for transporting high-pressure hydraulic oil.

The high-pressure circuits of excavator booms, sticks, and bucket cylinders; the hydraulic systems of crane telescopic booms and outriggers; and the high-pressure transmission hoses of mining equipment all rely on large-diameter high-pressure hoses to transmit power, ensuring precise, stable, and powerful equipment movements.

Most of them adopt SAE100 R1/R2/R16/R17, EN853 1SN/2SN, EN857 1SC, 2SC steel wire braiding, SAE100R9/R12/R13/R15, EN856 4SP/4SH steel wire winding reinforcement structure, with a nominal diameter covering 3/16” ~ 4”. They can withstand ultra-high working pressure and have excellent anti-pulse, anti-tensile, and wear-resistant properties, perfectly adapting to the high-frequency start-stop and large pressure fluctuation operation characteristics of heavy industrial equipment.

135℃ Air Compressor Hose: Dedicated Hose for High-Temperature Operations

Air compressors are commonly used equipment in construction machinery operations, widely applied in tunnel construction, mining drilling, and infrastructure pneumatic tool operations.
They primarily serve various large industrial air compressors and mobile construction air compressors, ensuring the stable operation of the air compressor’s lubrication and cooling systems, and continuously providing a stable air source for construction machinery tools such as pneumatic drills, pneumatic wrenches, and crushing equipment.

Long-term continuous operation generates a large amount of heat. Air compressors must withstand the continuous high-temperature impact during operation and resist corrosion from hydraulic oil and lubricating oil, preventing aging and leakage in hoses, and oil line blockages. Ordinary pipelines are highly susceptible to softening, leakage, and aging failure.

Fuel and gas hose: the lifeline for energy transmission in construction machinery

As a key carrier of energy transmission, fuel and gas pipes directly affect the start-up efficiency, operational stability, and safety of equipment, making them indispensable core components of construction machinery.

Made of high-density, corrosion-resistant materials, these hoses possess excellent resistance to oil and gas penetration, aging, and pressure sealing, eliminating the risk of fuel and gas leakage. They are also adaptable to varying high and low temperature conditions, unaffected by outdoor exposure to sunlight, freezing temperatures, and dust and oil contamination, making them suitable for various fuel and gas-powered construction machinery.

Choosing the right rubber hose can save you a lot of trouble later on, such as leak repairs and system downtime.
