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.


Work Made Easy

OPTIMIZED Z-BAR LINKAGE

The optimized Z-bar linkage combines the digging efficiency of a traditional Z-bar with integrated tool carrier capabilities for great performance and versatility. Visibility to bucket corners and fork tips at ground level remain excellent while sight lines at maximum lift are improved with a Generation III lift arm design. Lift higher and reach further with optional High Lift linkage available on all three models.

QUICK LOADING PERFORMANCE SERIES BUCKETS

Performance Series Buckets deliver up to 10% higher fill factors compared to previous models, better material retention for significant productivity and fuel efficiency improvements. The buckets feature a longer floor to take a bigger bite of the pile, an open throat to heap higher and curved side bars to help with material retention.

Sustainability
  • The Cat® C7.1 engine meets U.S. EPA Tier 4 Final, EU Stage V and Korea Tier 5 emission standards.
  • Engine Idle Management System (EIMS) helps maximize fuel efficiency and reduce greenhouse gas emissions while maintaining machine performance.
  • Engine Idle Shutdown Timer reduces fuel burn, greenhouse gas emissions and unnecessary idle time by shutting down the machine after a pre-set idling period.
  • Performance Series Buckets have rounded side boards, a longer floor and open angle to carry more and load quicker so each pass is the most efficient.
  • Rimpull Control is a quick way to adjust the torque to the tires for less slipping and tire wear.
  • Cat® Production Measurement provides real-time payload weighing which help you maximize productivity, reduce fuel burn and greenhouse gas emissions, all while improving job site efficiency and lowering costs.
  • Extended maintenance intervals not only reduce downtime but decrease the amount of fluid and filters that are replaced over the life of the machine.
  • Power on Demand, transparent to the operator, provides full-time efficiency and power when you need it.
  • Tire Pressure Monitoring provides real-time tire pressure information to the operator to help increase tire wear and achieve better fuel efficiency and reduced greenhouse gas emissions.
  • Intelligent Hystat Transmission helps improves control and reduces fuel consumption and greenhouse gas emissions in load and carry applications.
  • Variable Displacement Pumps match power to load as application requirements change.
