Applicable Equipment
This 4720873 Controller is specifically designed for the following Hitachi gigantic hydraulic excavators:
Hitachi EX2600-6BH
Hitachi EX2600-6LD
Hitachi EX5600-6BH
Hitachi EX5600-6LD
Application Scenarios and Case Studies
The Hitachi EX2600-6 and EX5600-6 series excavators, powered by robust components like the 4720873 Controller, are engineered for "massive production" and "large-sized production." These machines are indispensable in demanding heavy construction and mining environments.
Typical Application Scenarios:
Large-Scale Mining Operations: Used for overburden removal, ore extraction, and loading large mining dump trucks (e.g., EH3500AC-3, EH4000AC-3, EH5000AC-3 models for EX5600-6).
Quarrying: Efficiently breaking and loading rock in quarries for aggregate production.
Major Infrastructure Projects: Ideal for large-scale earthmoving, dam construction, and highway development where significant material handling is required.
Case Study Example:
In a large open-pit coal mine, a fleet of Hitachi EX5600-6 excavators, equipped with reliable controllers, was instrumental in maintaining high production targets. The precision control offered by the controller allowed operators to optimize digging angles and bucket fill factors, leading to a 15% increase in daily material moved compared to older models. The robust design of the controller ensured continuous operation despite extreme temperatures and heavy vibrations, significantly reducing unscheduled downtime and contributing to the project's overall profitability.
Related Similar Products
Beyond the primary controller, various other electronic and hydraulic components are integral to the seamless operation of Hitachi excavators. These products share the same commitment to quality and compatibility:
Hydraulic Control Valves: Crucial for directing hydraulic fluid flow, working in conjunction with the controller for precise movement. Applicable to all Hitachi hydraulic excavators.
Sensors (Pressure, Temperature, Position): Provide real-time data to the controller for optimal system adjustments and diagnostics. Applicable across all Hitachi excavator models.
Wiring Harnesses: Essential for transmitting signals and power throughout the electrical system, including to and from the controller. Specific harnesses exist for different sections (e.g., cab, engine) of EX2600-6 and EX5600-6 series.
Diagnostic Tools & Software: Such as Hitachi MPDr (Maintenance Pro) software, which interfaces with the controller to monitor performance, read fault codes, and assist in calibration. Essential for maintenance and service of all modern Hitachi excavators.
Engine Control Modules (ECM): While the 4720873 is a general machine controller, dedicated ECMs manage engine specific functions, often communicating with the main controller. Applicable to all engine-powered Hitachi excavators.
Installation and Maintenance Insights
Proper installation and regular maintenance are vital for maximizing the lifespan and performance of your 4720873 Controller and the overall excavator.
Common Installation Considerations:
Mounting Orientation: Always fasten the mount base to a vertical surface to ensure proper heat dissipation and prevent overheating, which can damage the module.
Static Electricity Prevention: Discharge any static buildup from your body before handling and installing the module, as static electricity can cause defects.
Tightening: Properly tighten all screws to prevent malfunctions, smoke emission, or combustion.
Environmental Protection: Prevent foreign matter (dust, debris) from entering the module. If the controller might get wet, install it within a drip-proof enclosure.
Cable Routing: Ensure communication, power supply, and motive power cables are routed separately. Keep motive power cables (from inverter, motor, power regulator) at least 300 mm away from other cable types to avoid electromagnetic interference.
Common Maintenance Issues & Solutions:
Overheating: If the controller operates at excessively high temperatures, check for proper mounting orientation and sufficient ventilation. Consider increasing mounting intervals or providing forced air cooling with a fan if needed.
Poor Electrical Contact: Dust or foreign matter on connectors can lead to poor contact. Regularly inspect and clean connectors. Perform mounting and wiring promptly after unpacking to minimize exposure.
Electromagnetic Interference (EMI): Malfunctions can occur due to EMI from nearby equipment or improperly routed cables. Ensure proper cable separation during installation.
Fault Codes & Diagnostics: The controller can trigger fault codes indicating issues within the electrical or hydraulic systems. Utilize Hitachi diagnostic software (e.g., MPDr Maintenance Pro or Jaltest Software) to read, analyze, and clear these codes. The software often provides detailed explanations and necessary corrective actions.
General System Issues: Problems like air in hydraulic systems, leaks, pump issues, or contaminated hydraulic fluid (often monitored by the controller via sensors) require prompt attention. Regular visual inspections, fluid level checks, and fluid analysis are crucial.
For complex issues, always consult your Hitachi service manual or a certified technician.
