Cranes

HED has developed custom solutions to meet the rigorous requirement of the crane industry, including a complete Load Moment Indicator (LMI) system.  For controlling the hydraulically driven boom functions to controlling lights and wipers, HED can provide a complete multiplexed solution that will reduce the cost and complexity of your crane.

Potential Applications

Boom Functions

• Controlling boom functions with a closed-loop PWM signal for excellent proportionality and fine metering
• Input modules to convert discrete and proportional analog sensor into CAN

Outriggers

• CAN based Keypad to simply the wiring for driving your outriggers

Cab Function

• Broad line up of displays to integrate engine and vehicle controls and diagnostic information
• Keypad for the cab to control lighting
• Engine and Transmission Control
• Ability to control and monitor the engine and transmission

Misc Functions

• Datalogger up to 16GB with optional Wi-Fi communication to log critical events
• Fleet management via a fully functional Telematics system including the ability to download in application code remotely to the vehicle
• Complete LMI control using a 32 bit processor and proven LMI equations
• High current Power modules to drive lights and wiper (up to 40 amps per output)

Future Flexiblity

• User friendly software to allow you to modify and update your control system as required 

Advantages

Cost Effective

• Distributing the vehicle controls will significant reduce wiring harness and slip-ring costs
• Reduced Installation Cost
• Lower Cost of Ownership
• Reducted Warranty Cost
  • Reduced wiring
  • Robust products

Increased Performance

• Closed-loop current control (up to 5mA accuracy) for fine metering and a smooth swing/ slew
• LMI system can monitor the lifting condition of the vehicle

Improved Efficiency

• Ability to coordinate functions (lift, extend, etc.)
• Ability to coordinate subsystem (hydraulic, lighting and powertrain) to maximize fuel efficiency

Enhanced Flexibility

• User-friendly software allows you to modify functionality in the field
• Telematics allow you to download new functionality remotely from the web
• CAN based, distributed system allows module to be added quickly to the system
