Doosan DX300LC-9C 30-ton Heavy Duty Crawler Hydraulic Excavator

1. Powerful & Fuel-Saving Power Assembly

The DX300LC-9C adopts original Doosan DL08 six-cylinder turbocharged engine, delivering strong torque at low speed. The intelligent electronic control system automatically adjusts power output according to construction load, cutting fuel waste by 10–15% compared with old models. It adapts to low-quality diesel in overseas construction sites and has stable performance under high-temperature, dusty mine environments. The engine’s reinforced structure extends overhaul intervals to over 10,000 working hours, lowering your maintenance cost.

2. Efficient & Stable Hydraulic Control System

Dual independent variable hydraulic pumps provide sufficient flow for simultaneous multi-action operation (digging, slewing, moving, lifting at the same time) without power lag. The upgraded main control valve reduces hydraulic loss, boosting digging efficiency. Thickened hydraulic oil pipes and high-strength oil cylinders resist impact and leakage during heavy rock digging. Multiple working modes (Standard / Heavy / Economy) can be switched with one button to match different construction tasks.

3. Super Durable Chassis & Structural Frame

The extended long crawler (LC version) enlarges ground contact area, greatly improving stability on mud, mountain and uneven ground. The track frame uses thickened wear-resistant steel plates, and track rollers, idlers and sprockets are heat-treated for anti-abrasion. The boom, arm and bucket adopt integrated casting reinforcement at stress points, resisting bending and cracking under heavy load mining and demolition work. The whole machine body has anti-rust paint coating to extend service life in humid regions.

4. Humanized Safe Operator Cab

The fully sealed large cab comes with sound insulation and shock absorption suspension seats to reduce vibration and noise during long shifts. Large panoramic front and side windows bring 360° clear vision to avoid construction blind spots. The air conditioning system works stably in extreme hot or cold weather. Centralized control touch screen displays real-time fuel consumption, hydraulic pressure, engine fault codes and maintenance reminders. Safety handrails and anti-slip foot plates are installed on the machine exterior for convenient daily inspection.

5. Wide Application Scenarios

This 30-ton Doosan excavator fits all medium-to-large construction projects: open-pit mining, highway & bridge foundation digging, urban building demolition, river dredging, farmland leveling, port cargo handling, stone yard loading. It supports quick connection of attachments including breakers, grapples and rippers to realize multi-functional operation.
