Bulldozer spare parts hoses are flexible pipes used to connect key components such as hydraulic systems, fuel systems, and cooling systems. They primarily function to transport media such as hydraulic oil, fuel, and coolant. Depending on their application, they can be divided into hydraulic hoses, fuel hoses, and cooling water hoses, etc., and must possess characteristics such as high pressure resistance, oil resistance, and heat resistance to adapt to the complex working conditions of construction machinery.

Main Types and Functions

Hydraulic hoses are used to transmit hydraulic power and are typically composed of multiple layers of steel wire reinforcement and oil-resistant rubber. They must withstand high pressure (e.g., the burst pressure of Litong brand hoses reaches 180MPa). For example, the 07113-00506 hose used in the Shantui SD32 bulldozer belongs to this type.

Fuel hoses are specifically designed for fuel systems and must be corrosion-resistant and have high sealing performance. For example, the fuel lines (part number 304-3706) on the Caterpillar D5K bulldozer are manufactured to original factory standards.

The coolant hoses connect the radiator to the engine and deliver coolant. The water tank hoses (part number 115R-03-00006) on the Shantui DH24 bulldozer are original factory parts.
