Wheel loaders are pivotal in mining, where they handle and transport heavy materials in demanding environments. These machines must operate with precision and reliability to ensure the efficiency and safety of mining operations. Among the many hydraulic systems that power these machines, this paper focuses on the specific hoses that keep the boom bucket lift/tilt and axle cooling circuits functioning at their best.
Boom and Bucket Lift and Tilt Circuit
The boom and bucket Lift and tilt hydraulic circuits are responsible for lifting, moving, and tilting heavy materials, making them central to the loader’s functionality. The hoses and fittings used in this circuit must withstand high pressures and offer exceptional durability to ensure consistent performance.
This R12 four-spiral hose is a top performer in the lift and tilt circuit, exceeding multiple standards for high-pressure capabilities. Its robust design ensures it can handle the rigorous demands of lifting and tilting operations, providing reliable service life in heavy-duty environments.
Winner EC420 Hose:
This four-wire spiral R13 hose is engineered for moderate spiral applications but meets critical hose certifications. It provides a competitive price for standard hydraulic applications within the boom and bucket circuit, ensuring the system operates smoothly and efficiently even under heavy loads.
Weatherhead H600 Hose:
This hose offers outstanding flexibility with a ½ bend radius, making it ideal for compact routing applications and easier installation in tight spaces. It’s a go-to solution for demanding lift and tilt circuits where flexibility and ease of installation are crucial.
Weatherhead H400 Hose:
This two-wire braided constant-pressure hose is rated up to 275 bar [4,000 psi]. It is highly suitable for general hydraulic applications in the boom and bucket circuits.
Danfoss Hansen flat face (FF) quick disconnect couplings are integral to this circuit, providing high flow rates and industry-leading performance at higher pressures. These couplings enable quick and secure connections without fluid leakage or contamination during maintenance or when attachments must be swapped out quickly.
Axle Cooling Circuit
The axle is a critical component in a wheel loader, transferring power from the engine to the wheels and bearing the machine’s weight during operation. This hydraulic circuit is essential for maintaining the proper temperature of the wheel loader’s axles. The hoses in this circuit must withstand high temperatures and provide reliable fluid transfer to prevent overheating.
Weatherhead H180 Hose:
This one-wire braided hose is a reliable choice for applications where a durable, high-performance hose is needed. The H180 can sometimes replace more costly two-wire braided hoses, offering a cost-effective solution without compromising quality.
Weatherhead H250H Hose:
This flexible 100R5 two-braid high-temperature hose is designed to handle the extreme temperatures often associated with axle cooling systems. Its flexibility and durability make it ideal for maintaining the necessary fluid flow to keep the axles cool and operational.
Weatherhead H009 Hose:
This single textile braided control line hose is designed with inner tubing and an external cover that are highly resistant to temperature. It provides a flexible and lightweight solution for pilot lines and general hydraulic systems within the axle cooling circuit, ensuring efficient cooling and long service life.
