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.
