Excavatrice d'occasion Hyundai 305-9T à vendre

The 9T Engineering Logic: High-Torque Mechanical Reliability

The 9T designation signifies 'Rugged Simplicity', prioritizing mechanical leverage and cooling efficiency over fragile digital sensors. Unlike digital-first generations, this 30-ton heavy-lift excavator uses a traditional mechanical fuel system and reinforced architecture. Our pre-sale audit focus on heavy-duty boom-pivot castings and arm-box welds ensures the structural mass needed for consistent rock-digging or heavy-breaker operation without the metal fatigue common in lighter models.

Powerplant: The 8.3L Cummins 6C Advantage

Powered by the massive Cummins 6C8.3 engine (8.3L), a six-cylinder block prized for naturally aspirated torque and zero-fear reliability. The 6C block delivers maximum torque at low RPMs, extension major overhaul intervals. We conduct 150-point diagnostics, including fuel-injector audits and blow-by analyses. Verification videos prove stable engine performance under full hydraulic stall, ensuring reliability for high-heat or remote mining regions where parts and knowledge for the 6C are universally available.

Heavy-Duty Hydraulic Synergy: The Production Multiplier

Engineered for 500+ L/min oil flow, utilizing oversized Kawasaki control valves to reduce heat during 24/7 mining support. This synergy allows for lightning-fast cycle times required in bulk production. We perform comprehensive fluid analysis and multifunction synchronization tests. audited units show zero hesitation during simultaneous lift-swing-track cycles, translating into more metric tons moved per liter of fuel consumed than any standard 20-ton unit.

Digging Forces and Structural Over-Engineering

Features a 190kN+ breakout force and reinforced mining-grade boom with internal baffle plates to resist torsional stress. The heavy-duty undercarriage supports 30 metric tons on abrasive quarry floors. We measure wear on triple-grouser steel tracks and drive sprockets. A straight, factory-reinforced undercarriage is essential for contractors in port construction and dam projects where high-capacity lifting is a daily operational requirement.

Operator Safety: The Heavy-Production Cab Suite

The ROPS-audited cab is a sound-attenuated command center designed for 12-hour production focus. High-back suspension seating and pilot controls minimize fatigue. We verify HVAC performance to maintain a dust-free, cool environment in extreme tropical heat. Elevated cab positioning provides superior visibility of dump trucks and personnel, critical for safety in high-volume production zones.

Strategic Heavy Application Scenarios

Ideal for quarry loading (filling 30-ton trucks), land reclamation, and mining overburden removal. The massive counterweight and 1.5m³ bucket make it a superior choice for industrial water connections and heavy pipe placement. It serves as A high-performance 'Production Multiplier' for fleets, offering massive digging force with significantly more mobility than a full mining shovel.

Attachment Versatility: The Heavy Tool Carrier

Factory-wired for high-pressure auxiliary hydraulics, capable of powering 2000kg+ breakers or large augers. We verify flow-rates to sustain peak performance for heavy-duty attachments. Lihang can source and pre-install rock buckets or rippers in our Shanghai yard before shipping, ensuring your asset is revenue-generating from the first hour it arrives at your destination port.

Global Logistics: Flat Rack and Ro-Ro Shipping Strategies

We manage complex 40-foot Flat Rack (40FR) or Ro-Ro logistics for efficient global heavy-asset export. Booms and sticks are removed for safe height clearance and professionally lashed. Our export team handles all specialized documentation (SABER/CCIC/BV). Every buyer receives a 'Loading Evidence File' documenting the multi-point blocking process required to ensure the machine arrives in its original yard condition.

Why a Used 305-9T is a Blue-Chip Heavy Asset?

The 9T series represents the Golden Era of mechanical durability, offering elite speed with rugged structural frames. We selectively source from regulated domestic Chinese projects with confirmed maintenance history. Selective sourcing ensures that the Cummins 6C engine and heavy-duty boom retain at least substantial productive life life, offering a superior uptime-to-maintenance ratio in remote export markets.
