Hengshui Zhehan Rubber & Plastic Products Co., Ltd. focus on the R&D, production, and direct supply of hydraulic rubber hoses. Our range covers complete lines for construction machinery, agricultural equipment, trucks, mining machinery, and marine hydraulic systems. All products are built to recognized international standards — ISO, EN, and SAE — giving overseas buyers access to both standard and custom-engineered hydraulic hose solutions with reliable compatibility.
This Hydraulic Hoses For Construction Machinery is purpose-built for heavy construction equipment, one of the most frequently purchased categories in export. It is engineered for the combination of frequent start-stop cycles, high-pressure surges, and continuous high-load operation typical of heavy machinery.
How does a hydraulic hose improve the stability and safety of construction equipment?
The answer comes down to a dedicated high-impact resistance structure and wear-resistant protection — advantages that general-purpose hydraulic hoses cannot offer to the same level.

The Hydraulic Hoses For Construction Machinery is built with a multiple-layer steel wire spiral reinforcement process, allowing a working pressure of up to 42 MPa. Burst pressure ratings exceed international standard requirements by a clear margin, and the hose shows strong resistance to sudden pressure spikes — a necessary feature for hydraulic drive systems on excavators, loaders, cranes, rollers, and similar machines. The outer rubber cover incorporates wear-resistant and flame-retardant additives. This gives it good resistance to abrasion, stretching, and environmental aging, so it can handle rubbing against job-site debris, prolonged sun and rain exposure, and the vibration load of heavy equipment without developing bulges, cracks, or oil seepage over long operating hours. At the same time, the hose remains flexible enough for routing through tight equipment spaces, making installation straightforward.
This hose is used across the hydraulic power, control, and oil supply systems of excavators, bulldozers, loaders, cranes, rollers, graders, shield tunneling machines, and other construction machinery. It serves as a core hydraulic hose component in infrastructure projects, mining operations, and road construction environments.
