Data from customer machines show Cat wheel loaders are among the most fuel efficient machines in the industry. Several features contribute to this excellent fuel efficiency:
Performance Series Buckets – Deliver faster fill times and better material retention, ultimately reducing cycle times while improving productivity and fuel efficiency.
Positive Flow Control Hydraulics – Provides only the hydraulic flow required by the implement and steering systems for improved fuel efficiency and greater rimpull.
ACERT Engine – Advanced engine controls maximize power and efficiency.
Economy Mode – Featuring On Demand Throttle, Economy Mode optimizes power for maximum fuel savings with minimal impact on production.
Engine Idle Shutdown – Automatic engine and electrical system shutdown conserves fuel.
Lock-up Torque Converter – Transfers more power to the ground and optimizes fuel efficiency in all applications.
Machine configuration, operator technique, and job site layout can impact fuel consumption.
Machine Configuration – Select the correct work tool and tire type based on machine application. Ensure proper inflation pressures. Utilize the Economy Mode setting for maximum efficiency.
Job Site Layout – Spot loading targets in the right position. Avoid traveling more than 1.5 tire revolutions during truck loading cycles. Reduce transport distance for load and carry cycles by optimizing job site layout.
Loading Bucket – Load in first gear. Raise and tilt bucket quickly and do not use a “pumping” motion. Avoid lift lever detent and use impeller clutch.
Loading Truck or Hopper – Do not raise the work tool any higher than necessary. Keep engine rpm low and unload in controlled manner.
Idle – Set the parking brake to engage Engine Idle Management System.
