Application Scenarios & Case Studies
Hydraulic hoses are the lifelines of any hydraulic system, transmitting fluid power to various components for movement and operation. The 4647858 hydraulic hose plays a vital role in powering critical functions of HITACHI excavators across diverse applications:
Construction Sites: In urban development, road construction, and building foundations, excavators rely on robust hydraulic systems for digging, lifting, and material handling. A reliable hydraulic hose like the 4647858 ensures uninterrupted operation during demanding excavation tasks, preventing costly delays.
Case Study: A large infrastructure project experienced frequent hose failures on their HITACHI excavator due to using aftermarket parts. After replacing them with genuine 4647858 hoses, the excavator's uptime significantly increased, leading to project completion ahead of schedule.
Mining Operations: Excavators in mining are subjected to extremely harsh environments, including abrasive materials, extreme temperatures, and continuous heavy-duty cycles. The durability and pressure resistance of the 4647858 hose are critical for maintaining the efficiency and safety of mining operations, where machinery failures can lead to significant production losses.
Case Study: In an open-pit mine, a HITACHI excavator equipped with 4647858 hydraulic hoses demonstrated extended service intervals compared to other machines using inferior hoses, showcasing the product's resilience in challenging conditions.
Demolition Work: High-impact forces and continuous movement are characteristic of demolition sites. The hydraulic system, supported by high-quality hoses, enables precise control and powerful breaking capabilities. The resilience of the 4647858 hose helps prevent blowouts under sudden pressure surges during demolition.
Case Study: A demolition company reported a noticeable reduction in hydraulic fluid leaks and hose replacements on their HITACHI excavators after standardizing on the 4647858 hose, improving both safety and operational efficiency.

Installation & Maintenance: Common Issues and Solutions
Proper installation and routine maintenance are crucial for maximizing the lifespan and performance of your hydraulic hoses. Here are some common issues and their solutions:
1. Hose Abrasion:
Problem: Hoses rubbing against other components, sharp edges, or the ground, leading to outer cover wear and potential failure.
Solution: Use hose clamps, protective sleeves, or routing clips to keep hoses away from abrasive surfaces. Regularly inspect for wear and reroute if necessary.
2. Incorrect Installation/Bending Radius:
Problem: Hoses installed with bends tighter than the recommended minimum bending radius can cause internal damage, leading to premature failure. Twisting during installation also compromises hose integrity.
Solution: Always adhere to the manufacturer's specified minimum bending radius. Ensure hoses are not twisted during installation (check the layline for straightness). Use correct fittings and ensure they are tightened to the specified torque.
3. Fluid Contamination:
Problem: Contaminants in the hydraulic fluid can damage the inner tube of the hose and other hydraulic components, leading to leaks or system malfunction.
Solution: Regularly check and replace hydraulic filters. Use clean, high-quality hydraulic fluid as recommended by HITACHI. Ensure all caps and plugs are securely fitted when not in use.
4. High Temperature Exposure:
Problem: Continuous exposure to temperatures exceeding the hose's maximum operating temperature can degrade the hose material, leading to hardening, cracking, and premature failure.
Solution: Ensure the hydraulic system is operating within its normal temperature range. Check for proper cooler function. If the hose is consistently exposed to high heat, consider using hoses with higher temperature ratings or adding heat shields.
5. Pressure Surges and Pulsation:
Problem: Repeated rapid changes in pressure can fatigue the hose reinforcement, leading to burst or weeping.
Solution: Ensure the hydraulic system is properly maintained to minimize excessive pressure surges. Replace hoses with the correct pressure rating for the application. Regular inspections can identify early signs of fatigue.
General Maintenance Tip: Perform daily visual inspections of all hydraulic hoses for any signs of wear, leaks, bulges, or kinks. Replace damaged hoses immediately to prevent more extensive system damage and ensure operator safety.
