CAT® C7 Engine with ACERT™ Technology

ACERT™ Technology works at the point of combustion to optimize engine performance and provide low exhaust emissions to meet U.S. EPA Tier 3 emission regulations, with exceptional performance capabilities, fuel efficiency and proven reliability.

Operator Station

The new cab, equipped with a 2.6 m (8'6") hydraulic cab riser provide improved visibility and comfort. The new monitor is a full-color graphical display with enhanced functionality to provide a simple, comprehensive machine interface.


Caterpillar's design and manufacturing techniques deliver outstanding durability and service life. Booms and sticks, made up of welded box-section structures, are fabricated with thicker plates to withstand high stresses.


The hydraulics system provides efficient performance, unmatched in the industry, designed to provide reliability and outstanding controllability with increased lifting capacity. The Heavy Lift Mode maximizes lifting performance while maintaining excellent stability.

Work Tools - Attachments

Orange Peel Grapples and magnets are offered to maximize performance of the M325D MH and M325D LMH.
