Cat 352 Large excavators tech specs

Overview

The Cat 352 (2021–2026) is a large excavator designed for heavy earthmoving, quarry operations, foundation excavation, and major infrastructure projects. With a 48,900 kg operating weight, 332 kilowatt Cat C13B diesel engine, and 267 kN bucket digging force, it provides substantial digging and loading performance. Its 3.3 m³ bucket capacity, 8.21 m digging depth, and 12.15 m digging reach make it suitable for high-volume excavation and demanding material handling operations.

Expert rating: 5 stars

Performance & Efficiency

The Cat C13B diesel engine produces 332 kilowatt gross power, providing substantial output for bulk excavation and hydraulic operations. Its 267 kN bucket digging force and 183 kN arm crowding force support digging through compacted material, while the 3.3 m³ bucket handles large volumes per loading cycle. The 779 L/min hydraulic pump flow and 350 bar relief valve pressure support coordinated boom, arm, and bucket movements. With an 8.21 m digging depth, 12.15 m digging reach, and 8.3 rpm swing speed, the machine can cover large excavation areas and load haul trucks efficiently. Its 329 kN drawbar pull, 35-degree gradeability, and maximum travel speed of 4.8 km/h support movement around prepared construction sites.

Maintenance & Ownership

The Cat C13B diesel engine requires regular servicing to maintain consistent performance in demanding excavation conditions. Its 715-liter fuel tank, 217-liter hydraulic fluid capacity, and 40-liter engine oil capacity reflect the maintenance requirements of a large production excavator. Owners should inspect hydraulic hoses, cylinders, pumps, bucket teeth, boom pins, and arm bushings regularly. The 5.37 m track length and 60 cm track width provide a substantial ground-contact footprint, but track chains, rollers, sprockets, and idlers can be costly to replace. Caterpillar's parts and service network provides useful support for long-term ownership.

In Cabin

The Cat 352 features an elevated operator cab with a 3.23 m height, providing visibility toward the bucket, excavation face, and surrounding loading area. Hydraulic controls support coordinated digging and swinging movements, while the 8.3 rpm swing speed helps operators manage repeated excavation cycles. Clear visibility is particularly important when positioning the 1,950 mm wide bucket near haul trucks and site structures. Cab equipment varies by configuration, and buyers should assess seating, climate control, monitoring systems, visibility, and control response when inspecting used machines.

In Comparison

Cat 349: A closely matched large excavator with strong digging and loading capability for bulk earthmoving and quarry applications.
Komatsu PC450: A heavy excavator suited to major construction, foundation excavation, and high-volume material handling, with performance depending on generation and configuration.
Cat 352: Combines a 48,900 kg operating weight, 332 kilowatt engine, 267 kN bucket digging force, and 779 L/min hydraulic flow for demanding excavation and loading operations.

Final Verdict

Rated 5 stars, the Cat 352 offers strong digging performance, substantial bucket capacity, and high hydraulic output within the AED 300,000–650,000 range. It remains a capable choice for quarry operations, major infrastructure projects, and bulk earthmoving, provided the engine, hydraulic system, boom components, and undercarriage are in good condition.
