Tier 4 Overview

    Doosan DX300LC (iT4) Crawler Excavator (Interim Tier 4)

    • Improved production
    • Premium comfort
    • Excellent reliability
    • Reduced maintenance

    In the 28-33 metric ton size class, few machines match the DX300LC. It has the horsepower to tackle larger projects but is designed to keep fuel and maintenance costs low.

    It shares the performance strengths of the Doosan excavator lineup. The high pressure common rail fuel injected engine teams with the EPOS (Electronic Power Optimizing System) for optimum power and fuel efficiency. The EPOS also provides four work modes, auto-idle and machine diagnostics. Work more effectively with multiple operating modes, easy to read display monitor and the precise control levers.

    The DX300LC complies with iT4 regulations using a three-fold systems approach that includes Cooled Exhaust Gas Recirculation (CEGR) along with a Diesel Oxidation Catalyst (DOC) and Diesel Particulate Filter (DPF). This engine optimization also delivers increased horsepower and torque.

    Compared to previous models, the DX300LC provides improved swing torque, digging force, lifting capacity and boom-up speed. Four selectable power modes give operators added control over the machine's performance and fuel consumption as they work.

    Using two boom float modes, operators can focus on their task while increasing the machine's efficiency. In float mode, the boom is allowed to move up and down freely, without hydraulic flow, making it ideal for finishing work and truck loading. In breaker mode, the boom freely moves downward, reducing machine and attachment wear while improving operator comfort.

    The larger, world-class cabin combines superior comfort, excellent visibility, low noise levels and a roomy environment. The reclining, height- and weight adjustable standard suspension seat has a headrest and adjustable armrest along with easier controls. Work naturally with the optional air suspension seat and simple controls. Enter and exit easily through the larger door opening. The high-performance air conditioning offers adjustable air flow and five operating modes.

    Designed for long life with a robust frame and reinforced superstructure, the DX300LC is built for reliability. Bushings and ultra-hard wear disks are designed for extended service intervals and steady performance. The permanently sealed and lubricated track links maximize uptime and reduce operating costs.

    Further reduce your operating costs with easy access to key checkpoints, the cooling system and other key components. Rely on excellent filter design, efficient air cleaner and centralized grease points.
