PERFORMANCE WITH LESS FUEL

The excavator uses up to 20% less fuel than the 320D2 GC in similar applications.
Match the excavator to the job using power modes; let Smart mode automatically match engine and hydraulic power to your digging conditions.
The advanced hydraulic system provides the optimum balance of power and efficiency while giving you the control you need for precise digging requirements.
Valve priority puts hydraulic pressure and flow where you command it to go for fast light- to medium-load cycle times.
Meets Brazil MAR-1 emission standards, equivalent to U.S. EPA Tier 3 and EU Stage IIIA.
Add auxiliary hydraulics to do more work with a range of Cat attachments.
VisionLink® provides actionable data insights for all assets - regardless of fleet size or equipment manufacturer. Review equipment data from your desktop or mobile device to maximize uptime and optimize assets.
Don't let the temperature stop you from working. The excavator has a standard high ambient temperature capability of 52º C (125º F) and cold start capability of -32º C (-25º F).

LOWER MAINTENANCE COSTS

Expect up to 20% less maintenance cost than the 320D2 GC (savings calculated over 12,000 machine hours).
Do all daily maintenance at ground level.
Boost productivity with proactive service reminders. The integrated vehicle health management system alerts the operator with step-by-step service guidance along with parts needed so you don't experience any unnecessary downtime.
Check engine oil level quickly and safely with the latest ground-level engine oil dipstick; fill and check engine oil on top of the machine with a conveniently located second dipstick.
Track your excavator’s filter life and maintenance intervals via the in-cab monitor.
No required maintenance on the Cat Clean Emissions Module.
Using Cat genuine oil and filters and doing your typical S∙O∙S monitoring will double the current service interval to 1,000 hours, giving you greater uptime to do more work.
The latest hydraulic oil filter provides improved filtration performance,anti-drain valves to keep oil clean when the filter is replaced, and longer life with a 3,000 hour replacement interval – 50% longer than previous filter designs.
The latest high-efficiency electric cooling fans only run when needed and reverse to keep cores free from debris.
S·O·S ports simplify maintenance and allow for quick, easy extraction of samples for fluid analysis.

RELIABILITY YOU CAN COUNT ON

Work up to 3000 m (9,840 ft) above sea level without de-rating.
Standard high-ambient temperature capability is 52º C (125º F) with cold start capability at –32º C (–25º F).
Auto warm up speeds up hydraulic oil warming in cold temperatures and helps prolong the life of components.
Three levels of fuel filtration protect the engine from dirty diesel fuel.
Grease sealed between track pins and bushings reduces travel noise and prevents debris from entering to increase undercarriage life.
The center track guiding guard helps keep the excavator track aligned when traveling and working on slopes.
The sloped track frame prevents mud and debris accumulation, helping reduce risk of track damage.

SAFELY HOME EVERY DAY

Access 100% of daily maintenance points from ground level – no need for you to climb on top of the excavator.
Keep your excavator secure with Operator ID. Use your PIN code on the monitor to enable the push button starting feature.
The standard ROPS cab meets ISO 12117-2:2008 requirements.
