Twin Disc Transmissions TD61-1180 ARFF

Features at a glance

  • Increased power and torque capacity to mate with modern 4-cycle high torque engines.
  • Full time all wheel drive with differential lock. 30-70 and 50-50 biasing differentials available for 4x4, 6x6 and 8x8 vehicles. Optional part time AWD system available.
  • High capacity PTO clutch with ability to shift on the fly at high speeds.
  • State of the art TDEC-400 electronic control system.

Benefits

  • Increased fire fighting efficiency: The Twin Disc transmission system permits faster shifts, rapid acceleration and precise control of vehicle speed to meet ground requirements and varying tractive conditions. The vehicle gets to location faster and starts pumping sooner to fight life-threatening fires quickly.
  • Ease of use: Advanced electronic control system tailored for ARFF vehicles integrates the control of drive mode, PTO engagement, PUMP AND ROLL mode and frees the vehicle operator to concentrate on his primary mission. Simple operation reduces training requirements.
  • Reduced downtime: Durable heavy-duty components, combined with electronic controls which prevent overspeed, shift shocks and reduce the effects of operator’s error, result in increased machine availability and less wear and tear on other machine components.
  • Extended service life: The 1180 Series transmission system utilizes the same components used in heavy-duty off-highway units. This assures long life in ARFF vehicle operation.
  • Integrated system components: Torque converter with integral power dividing, drop box-type transmission and advanced electronic controls are all designed to work together as a system rather than a collection of parts
