Excavadora usada CAT 308E2 CR en venta

The CR Logic: 360-Degree Operational Freedom

The CR designation signifies a fundamental geometry shift, ensuring tail-swing overhang is minimal compared to standard units. For used equipment buyers, this compact design translates directly into structural preservation. Because the machine can rotate freely in narrow alleys without rear-impact risk, a used 308E2 CR typically exhibits much less counterweight damage. Our pre-sale audit performs slew-motor brake tests to ensure absolute control when working near high-value urban infrastructure.

Powerplant: Turbo-Charged Cat C3.3B Performance

Powered by the Cat C3.3B (48.5 kW) turbo diesel, this 4-cylinder engine provides a substantial torque reserve for heavy lifting. The C3.3B is globally recognized for high-cycle reliability and thermal efficiency in extreme climates. We conduct rigorous diagnostics, including turbo boost and fuel-rail integrity check. Verification videos of cold-starts prove the compression is within factory-spec top-tier ranges, ensuring the machine is work-ready upon arrival.

High Definition Hydraulics (HDH) and Control Logic

The HDH system uses a variable-displacement pump and flow-sharing logic to automatically prioritize high-demand functions. This prevents jerky movements, providing automotive-smooth control for delicate utility work. Our yard audit tests 'multifunction synchronization'—tracking, lifting, and swinging simultaneously without RPM drops. The machine maintains over 60kN of breakout force, ensuring high productivity even after thousands of hours.

Digging Depth and The Swing Boom Advantage

A 4.15m digging depth and 7m reach provide utility-class performance in a midi-size footprint. The integrated Swing Boom allows offsetting the linkage independently of the cab's rotation, perfect for trenching parallel to walls. We inspect the boom-swing knuckle and offset cylinders for vertical play, ensuring laser-straight trenching where space is limited and public proximity is a safety factor.

Operator Environment: The Sealed Utility Cab

The pressurized cab features high-back suspension seating and pilot controllers modeled after 20-ton excavators. Visibility is maximized via curved glass for a 360-degree view. We verify the digital monitor functions for fuel consumption and auxiliary flow adjustment. Pressurized HVAC systems are tested for consistent cooling, essential for our international buyers in tropical or desert climates.

Strategic Application Scenarios for the 8-Ton Class

Ideal for deep utility mainlines, roadway barriers, and commercial foundation prep where 80kN power is needed. The 8.4-ton weight provides the necessary down-force for 500kg+ hydraulic hammers. Its zero-tail design allows safe operation next to live traffic lanes. This class is A high-performance 'Utility Support' asset, performing big machine work at roughly 40% of the standard utility-class operating cost.

Structural Over-Engineering: Carbody and Undercarriage

Features a heavy-duty X-frame architecture designed to shed mud and protect final drive components. We measure track wear and inspect the dozer blade's high-pressure cylinders. A straight, strong undercarriage is the base of your investment. We prioritize units showing zero side-play in rollers and idlers, ensuring a solid foundation for rocky and abrasive project environments.

Global Shipping: The 40HQ Consolidation Edge

Consolidating two 8.4-ton CR units into a single 40HQ container reduces per-unit ocean freight by over 45%. Single units also fit in 20GP containers for secure delivery. Our export team handles all documentation and inspections (SABER/CCIC/BV). Every buyer receives a 'Loading Evidence File' documenting the heavy-duty lashing required to ensure the machine arrives in its original yard condition.

Why E2 CR Models are Blue-Chip Assets?

Representing the Golden Era of Cat tech, the E2 CR retains premium value due to its mechanical-hydraulic simplicity. We source from low-intensity domestic Chinese projects with original paint and documented service history. Selective sourcing ensures the hydraulic cylinders and main control valves retain at least substantial productive life fatigue-life, offering superior uptime compared to newer, sensor-heavy models.
