Detailed Description and Application

The Used CAT 312 Excavator is a mid‑size hydraulic excavator engineered to deliver balanced productivity, fuel efficiency, and operator comfort. With a proven Cat C4.2 ACERT engine and a robust hydraulic architecture, the machine maintains consistent digging forces and smooth cycle times across general construction, trenching, utility installation, and site preparation tasks. This unit’s recorded 2,760 working hours reflect moderate use consistent with careful operation and regular servicing.

Core Performance and Efficiency

Powered by a 67 kW Cat C4.2 ACERT engine, the 312D family is designed for efficient fuel consumption while preserving rated power under load. The machine’s hydraulic system optimizes pump flow and work tool response for precise control during delicate operations and strong breakout forces when needed. These traits reduce cycle times and operating costs on medium-duty job sites.

Operator Environment and Controls

The cab on the 312D series was redesigned for improved visibility, ergonomics, and noise control. Intuitive control layouts, adjustable seating, and climate options enhance long-shift productivity and reduce operator fatigue. Clear sightlines to the bucket and immediate surroundings allow safer material handling and trench work in congested sites.

Durability and Serviceability

Structural components, including the undercarriage, boom, and stick, are built to handle repeated stresses of daily site use. Routine maintenance points are accessible to minimize downtime: engine access, filters, and hydraulic service points follow Caterpillar layout standards. Operating on Stage IIIA emission level, the engine retains reliability in regions where this certification is applicable.

Key Advantages at a Glance*

Balanced power-to-weight ratio for strong digging performance without excessive fuel burn.

• Comfort-focused cab design to improve operator endurance and control accuracy.
• Proven Cat engine and hydraulic components that simplify parts sourcing and field repairs.
• Versatile bucket capacity (0.5–0.52 m³) suitable for a wide range of earthmoving tasks.
• Transportable dimensions that ease logistics for regional deployments.

Typical Use Cases and Target Customers

The Used CAT 312 Excavator is well suited to contractors, rental fleets, municipal works departments, and utility installers who require a reliable mid‑size machine that balances cost and capability. Typical applications include foundation work, utility trenching, road construction, landscaping, and general site development. Rental operators benefit from its broad market acceptance and steady demand among project contractors.

Inspection, Transport and Delivery

Each machine is inspected against owner-supplied and factory-standard checkpoints to verify engine health, hydraulic integrity, undercarriage condition, and proper functioning of safety systems. Transport dimensions and the machine’s weight facilitate over-road shipping and vessel stowage. Delivery lead time is typically 15–20 days from confirmation, with supply capacity to support high-volume requirements.

Buying Considerations*

Confirm the service history and any refurbishment records; 2,760 hours suggests moderate usage but verify maintenance intervals.

• Match bucket size and hydraulic flow to the primary application to avoid under- or over-sizing for intended tasks.
• Assess undercarriage wear separately—track condition and sprocket life drive remaining useful life.

Check attachments compatibility (thumbs, quick couplers, tilt buckets) to broaden the machine’s utility.

Summary

The Used CAT 312 Excavator represents a pragmatic choice for buyers needing a dependable, well‑balanced excavator. It combines Caterpillar’s proven engine and hydraulic architecture with a comfortable operator environment and manageable transport footprint. For contractors and fleet managers seeking a cost‑efficient machine that retains parts availability and service support, this 2016 unit with documented hours and clear technical parameters offers a compelling value proposition.
