Telehandlers

HED has developed custom solutions to meet the rigorous requirements of the telescopic material handling industry, including a complete envelope control system. From controlling the hydraulically driven boom functions to controlling lights and auxiliary attachments, HED can provide a complete multiplexed solution that will reduce the cost and complexity of your telescopic material handler.

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 sensors into CAN
• Ability to have coordinated X-Y motion and electronic self leveling of the forks

Outriggers

• CAN based Keypad to simplify 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 auxiliary features such as attachments and lighting
• Ability to control and monitor the engine and transmission
• Electronic joystick control of the boom functions (lift, extend, fork tilt, frame tilt, etc.)

Misc Functions

• A camera that could be mounted at the end of the boom coupled with a display in the cab would provide an operator with better visibility during load placement at difficult heights
• Dataloggers with up to 4GB and optional Wi-Fi communication to log critical events
• Fleet management via a fully functional Telematics system including the ability to download application code remotely to the vehicle
• Complete envelope control using a 32 bit processor
• High current Power modules to drive lights and wiper (up to 40 amps per output)

Future Flexibility

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

Advantages:

Cost Effective

• Distributing the vehicle controls will significantly reduce the vehicle wiring harness especially for function at the end of the boom
• Reduced Installation Cost
• Lower Cost of Ownership
• Reduced Warranty Cost
  • Reduced wiring
  • Robust products

Increased Performance

• Closed-loop current control (up to 5mA accuracy) for excellent fine metering and smooth boom control
• Ability to coordinate functions (lift, extend, etc.) to the fork can move in the horizontal and vertical directions with ease
• Electronic fork leveling allowing the operator to auto level the fork before picking up a pallet

Improved Efficiency

• 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 modules to be added quickly to the system
