Download PDF Literature

The Cattron Group International AT16LHD and AT32LHD portable remote control systems provide reliable, efficient and convenient control of LHD equipment. This control system duplicates the manual controls in the cab of the load-haul-dump, allowing the operator to direct the equipment from a safer location.

 System Features
  • Designed to be mounted on high vibration mining machinery
  • AT16LHD incorporates 16 independent functions, plus run on/off outputs
  • AT32LHD offers up to 5 digital proportional functions, plus up to 7 independent, as well as run. Systems also available with custom PWM (pulse width modulation) configurations.
  • Multiple watchdog circuits
  • 2-digit system status display (acts as a central test point)
  • Automatic Safety Override (ASO) output monitoring
  • Addressing and time sharing to permit multiple units to share each radio frequency
  • Extremely high message security
  • Extensive self diagnostics
  • BCH data error
  • Auto select 12-24 VDC input power supply
  • Compatible with Autodig™
  • Optional joystick controller/transmitter styles with fiberglass or aluminum dustproof, waterproof high impact housings
  • CE, FCC and Industry Canada approved (contact the factory for information on other approvals)
