Air Conditioning System

Air Conditioning
The air conditioning system on this machine contains the flourinated greenhouse gas refrigerant R134a (Global Warming Potential = 1430). The system contains 1.9 kg of refrigerant which has a CO2 equivalent of 2.717 metric tonnes.

Application Specific Configuration

GUARD YOUR INVESTMENT
Choose from a complete range of optional guarding to protect your machine from the harsh environment of a waste handling application. The machine guarding is purpose built to protect the machine's major components and systems to keep you on the job and maximize production rates.

BREATHE CLEAN
Maximize your engine life and extend filter cleaning intervals with a turbine pre-cleaner. Keep cool with a reversing fan to purge the single plane, widely spaced core cooling package and brush-less sealed alternator. Breath clean with a powered RESPA system for the operator environment designed to eliminate 90% of the particulate in the air and filter the remaining 10%.

MAXIMIZE TIRE LIFE
Fine tune your wheel torque to match the underfoot conditions and maximize performance while extending tire life. Cat Waste Handlers feature wheel torque adjustments through an exclusive Rimpull Control feature designed to keep your operating costs low.

Efficiently Powerful

The Cat® C7.1 engine provides cleaner, quieter operation while delivering superior performance and durability through a high torque, low speed design. Caterpillar's exclusive Intelligent Power Management system monitors operator input and power availability to keep the machine working at peak efficiency and provide the operator with greater customization to suit their application.

A choice of Power Modes allows you to choose between maximum fuel efficiency or boosted power along with hydraulic speed.

STANDARD POWER MODE

  • Saves fuel and reduces cab sound levels
  • Biggest gains are seen during load and carry, snow removal and roading applications

PERFORMANCE POWER MODE

  • Enabled at the push of a button (HP+), boosts engine power by up to 10% and engine speed by over 12%
  • Increases hydraulic cycle times and productivity

Lock up and go with fully locking front differential axle that can be engaged on the move at full torque. Maximize your traction with optional Limited Slip Differential on the rear axle to keep you climbing.

Enjoy All Day Comfort

A spacious, quiet and comfortable operator environment helps keep you relaxed and productive throughout the day. Experience superior all around visibility with single piece front windshield, redesigned linkage and clean hydraulic lines routing.
