Premium Quality 4473388 HOSE for Hitachi Heavy Machinery
Product Overview: Hitachi Part 4473388 HOSE
The 4473388 HOSE is a critical component in the hydraulic systems of large Hitachi excavators and mining equipment. As a high-pressure hydraulic hose, its primary function is to safely and efficiently transfer hydraulic fluid between various components, such as pumps, valves, and cylinders. Reliable hydraulic hoses are indispensable for the smooth and powerful operation of heavy machinery working under extreme conditions.
Sourced for its durability and performance, our 4473388 HOSE is designed to withstand the high pressures, temperature fluctuations, and potential abrasions common in demanding construction and mining environments. Ensuring the integrity of your hydraulic hoses is paramount to maintaining machine performance, preventing costly leaks, and minimizing unplanned downtime.
Key Advantages & Selling Points
Robust Construction: Engineered with high-quality materials for exceptional resistance to pressure, abrasion, and environmental factors.
Reliable Performance: Ensures consistent hydraulic fluid flow, vital for the precise and powerful movements of your Hitachi heavy equipment.
Exact Fit: Designed to match the specifications required for compatible Hitachi models, simplifying installation and ensuring proper function.
Extended Service Life: Reduces the frequency of replacements, lowering maintenance costs and increasing operational uptime.
Prevents Leaks: High-integrity seals and construction prevent dangerous and inefficient hydraulic fluid leaks.
Applicable Hitachi Machine Models & Applications
The 4473388 HOSE is specifically designed for compatibility with several large-scale Hitachi excavators and mining shovels, known for their immense power and capacity in the most demanding applications. These models include:
Hitachi EX1900-5
Hitachi EX1900-6
Hitachi EX2500-5
Hitachi EX2500-6
Hitachi EX2600-6BH (Backhoe version)
Hitachi EX2600-6LD (Loading Shovel version)
Hitachi EX3600-5
Hitachi EX3600-6
Hitachi EX3600E-6 (Electric version)
These machines are workhorses in heavy-duty applications such as:
Open-Pit Mining: Used for high-volume overburden removal and ore loading in coal, iron, copper, and other mineral mines.
Example: An EX3600-6 efficiently loading massive dump trucks in a large iron ore mine.Heavy Construction Projects: Employed in large infrastructure developments like dam construction, large-scale earthmoving, and major quarry operations.
Example: An EX2500-5 handling bulk excavation for a major highway expansion.Quarrying: Breaking and loading large rock volumes in quarries for aggregate production.
Example: An EX1900-6 extracting and loading blasted rock in a granite quarry.
In these demanding environments, the reliability of every component, including the 4473388 HOSE, directly impacts productivity and safety.

Frequently Asked Questions (FAQs)
Q1: What is the specific function of the 4473388 HOSE in Hitachi excavators?
A1: The 4473388 HOSE is a hydraulic line responsible for transferring pressurized hydraulic fluid within the machine's hydraulic circuit. It connects specific hydraulic components, enabling the movement and operation of implements like the boom, arm, bucket, or supporting functions like swing and travel on models such as the Hitachi EX2500-6 or EX3600-6. Its precise location and function depend on where it is installed in the hydraulic system layout.
Q2: How can I tell if the 4473388 HOSE on my Hitachi machine needs replacement? (Troubleshooting & Repair)
A2: Inspect the hose regularly for signs of wear or damage. Look for:
External leaks (dampness, drips, or puddles of hydraulic fluid).
Cracks, cuts, or abrasions on the outer cover.
Bulges or blisters on the hose body, indicating internal damage.
Hose stiffness or hardening.
Twisting or kinking.
If any of these signs are present, the hose should be replaced immediately. Never attempt to patch or repair a damaged hydraulic hose; it operates under high pressure and failure can be dangerous. Always depressurize the hydraulic system before inspection or replacement.
Q3: What are some simple maintenance tips to extend the life of my hydraulic hoses, including the 4473388 HOSE? (Maintenance)
A3: Proper maintenance can significantly extend hose life:
Perform visual inspections regularly (daily walk-arounds are ideal).
Ensure hoses are properly routed and secured, avoiding sharp bends or contact with moving parts or hot surfaces.
Check and maintain the correct hydraulic fluid level and cleanliness. Contaminated fluid can degrade internal hose materials.
Use protective sleeves or guards in areas prone to abrasion or impact.
Avoid exceeding the machine's rated operating pressure.
