As global construction machinery and heavy industrial equipment rapidly evolve toward higher efficiency and energy-saving designs, the performance demands on core transmission components—specifically hydraulic hoses—have become increasingly stringent. Recently, a major technological breakthrough was achieved in the hose manufacturing industry with the global launch of a new generation of ultra-high pressure, lightweight hydraulic hoses.
This new series utilizes an innovatively developed high-strength alloy steel wire braided reinforcement layer combined with a modified synthetic rubber inner liner. While maintaining or even exceeding the pressure ratings of traditional high-pressure hoses (with working pressures elevated to over 420 Bar), the overall weight of the hose body has been successfully reduced by 20% to 25%, and the bend radius has been shortened by 15%. This innovation shatters the traditional physical limitation that “high pressure resistance must lead to high rigidity and heavy weight.”
Industry experts note that combining a lightweight profile with high flexibility not only significantly reduces the overall energy consumption of heavy equipment like large excavators and tunnel boring machines, but also greatly simplifies routing spaces inside complex mechanical structures, reducing installation and maintenance difficulties. Having passed over one million impulse fatigue cycles, this product demonstrates exceptional resistance to fatigue and abrasive wear. It is expected to see large-scale industrial application in the second half of the year, sparking a new wave of upgrades in construction machinery hydraulic systems.
