Hitachi Hydraulic Hose - Fabricate (Part No. 4645593)
Product Overview
The Hitachi Hydraulic Hose (Part No. 4645593) is a premium-quality, fabric-reinforced hydraulic hose designed for exceptional performance and durability in demanding industrial and construction applications. This hose is specifically engineered to withstand high pressures, abrasion, and harsh operating conditions, ensuring reliable fluid transfer within hydraulic systems. Its "fabricate" designation indicates its suitability for custom-length requirements and on-site assembly, offering unparalleled flexibility for various equipment configurations and repair needs.
Key Product Parameters & Advantages
Part Number: 4645593
Type: Hydraulic Hose - Fabricate
Material: High-grade synthetic rubber inner tube, multiple layers of high-tensile fabric reinforcement, and a durable, weather-resistant outer cover.
Pressure Rating: Engineered for high-pressure hydraulic systems, ensuring robust performance under intense operational loads. (Specific pressure ratings may vary based on diameter and can be provided upon request.)
Temperature Range: Excellent performance across a wide range of operating temperatures, maintaining flexibility and integrity.
Abrasion Resistance: Superior outer cover provides excellent protection against abrasion, cuts, and environmental degradation, extending service life.
Flexibility: Designed for ease of routing and installation, even in confined spaces.
Durability: Constructed for long-term reliability and reduced downtime, minimizing maintenance costs.
Versatility: "Fabricate" feature allows for custom lengths and fittings, adapting to specific machine requirements.
Applicable Equipment
This Hitachi hydraulic hose is compatible with a wide range of Hitachi heavy equipment and other machinery requiring robust hydraulic connections. Key applications include, but are not limited to:
Hitachi Excavators: Such as the EX series (e.g., EX120, EX200, EX300) and ZAXIS series (e.g., ZAXIS 120, ZAXIS 200, ZAXIS 330).
Hitachi Wheel Loaders: Including models like the ZW series.
Hitachi Dozers: Various models that utilize hydraulic systems for blade control and other functions.
Hitachi Cranes: For hydraulic lifting and operational mechanisms.
Other Heavy Construction and Mining Equipment: Any machinery requiring reliable hydraulic fluid transfer under high pressure and demanding conditions.
Application Scenarios & Case Studies
The versatility and durability of the Hitachi Hydraulic Hose (4645593) make it indispensable in various demanding environments:
Construction Sites: Used extensively in excavators for boom, arm, and bucket cylinder movements, enabling digging, lifting, and grading operations. For instance, on a large-scale highway construction project, a failing hydraulic hose on an excavator can halt critical progress. Replacing it with a custom-fabricated 4645593 hose ensures minimal downtime and keeps the project on schedule.
Mining Operations: Employed in heavy-duty mining excavators and loaders for tasks like rock breaking, material handling, and overburden removal. These environments are extremely abrasive; the superior outer cover of this hose provides crucial protection. A case in point is an open-pit mine where a loader's steering hydraulic line ruptured due to constant exposure to sharp rocks. The ability to quickly fabricate and install a replacement hose on-site prevented prolonged operational disruption.
Quarrying: Essential for the operation of crushers, screens, and drilling rigs, where high-pressure hydraulics are critical for processing raw materials. A quarry faced an issue with a hydraulic hammer hose being damaged by falling debris. Utilizing the fabricate option of the 4645593 hose, they could quickly create a specific length hose with the correct fittings, restoring the hammer's functionality without a lengthy wait for a pre-made part.
Forestry: Found in feller bunchers, skidders, and harvesters, where hydraulic power controls cutting, delimbing, and loading functions. The ruggedness of this hose is vital in rough forest terrains.

While part number 4645593 is a specific hydraulic hose for fabrication, we also offer a comprehensive range of related hydraulic components and hoses for various Hitachi equipment:
Pre-assembled Hydraulic Hoses: Factory-crimped hoses with specific fittings, ready for immediate installation. These are ideal for common replacement needs and precise OEM specifications. Applicable to all Hitachi excavators, loaders, and dozers.
Hydraulic Fittings and Adapters: A wide array of JIC, ORFS, NPT, BSP, and other standard fittings in various sizes and materials (carbon steel, stainless steel) to complement your hose fabrication needs. Essential for connecting hoses to pumps, cylinders, valves, and other hydraulic components across all heavy machinery.
Hydraulic Quick Couplings: For fast and easy connection/disconnection of hydraulic lines, particularly useful for attachments and implements on excavators and skid steer loaders.
Hydraulic Pumps: Main pumps, pilot pumps, and gear pumps for various Hitachi models, driving the entire hydraulic system. Applicable to excavators, loaders, and dozers.
Hydraulic Cylinders and Seal Kits: Replacement cylinders or seal kits for boom, arm, bucket, and other functions to restore full hydraulic power. Applicable to excavators, loaders, and various other hydraulic-driven implements.
Common Installation & Maintenance Issues and Solutions
Proper installation and regular maintenance are crucial for maximizing the lifespan of your Hitachi hydraulic hose. Here are some common issues and their solutions:
Issue 1: Hose Kinking or Twisting during Installation.
Solution: Always ensure the hose is installed without any twists or kinks. Proper routing is critical. Use hose clamps and routing guides where provided by the OEM. If fabricating, measure accurately to avoid excessive length that could lead to kinking when pressure is applied.
Issue 2: Leaks at Fittings.
Solution: Leaks often result from improper crimping during fabrication or incorrect torque during installation. For fabricated hoses, ensure the crimping machine is properly calibrated and the dies match the hose and fitting specifications. For pre-assembled hoses or during installation, use a torque wrench to tighten fittings to the manufacturer's recommended specifications. Inspect O-rings and sealing surfaces for damage before assembly.
Issue 3: Abrasion of Outer Cover.
Solution: Hoses rubbing against machine parts, other hoses, or sharp edges can lead to premature failure. Install hose guards, sleeves, or routing clamps to prevent contact. Regularly inspect hoses for signs of wear and address potential friction points.
Issue 4: Hardening or Cracking of Hose Material (Aging).
Solution: Exposure to extreme temperatures, UV light, and certain chemicals can accelerate hose degradation. While the 4645593 hose is designed for durability, regular visual inspections are vital. Replace hoses that show signs of cracking, blistering, or excessive stiffness, even if they aren't actively leaking, as this indicates impending failure.
Issue 5: Internal Contamination Leading to System Failure.
Solution: When fabricating or replacing hoses, ensure the new hose is clean and free of debris. Always cap open hose ends during storage and installation to prevent contaminants from entering the hydraulic system. Maintain a clean work environment when handling hydraulic components.
