Used Doosan DL503 5 Ton Front Wheel Loader For Quarry & Construction

Core Power & Hydraulic Performance
Power Unit
Powered by Weichai WP10G low-speed high-torque diesel engine, rated power 162kW / 2200rpm (220HP), meeting China National Stage III emission standard. It generates strong traction and breakout force, supporting continuous heavy-duty operation while cutting fuel consumption effectively.
High-Efficiency Hydraulic System
Adopts dual-pump flow combination technology to reduce power loss. Short total cycle time (lifting, dumping & lowering within 11.3s) ensures faster loading speed. Max breakout force reaches 176kN, easily digging compact soil and hard gravel. Standard bucket capacity 3.0m³, optional 2.7–5.0m³ rock or bulk buckets for different materials.
Stable & Flexible Chassis Structure
Reinforced thick steel chassis and optimized weight distribution maintain high tipping stability during side loading and high-lift dumping.
40° steering angle with small turning radius (6150mm), ideal for narrow construction sites, mixing plants and stockyards.
Four-speed planetary transmission, max travel speed up to 36.5km/h for quick site transfer. Max gradeability 30°, capable of climbing rough slopes.
Heavy-duty wide tires improve ground grip on muddy, uneven ground.
Comfort & Safe Operator Cabin
Panoramic large windows with thin pillars eliminate blind spots; optional bucket front view camera enhances loading safety.
Air-suspended shock absorption seat, low-noise sealed cabin and full air conditioning relieve long-hour operation fatigue.
Intuitive centralized control panel with clear real-time machine status display.
Low Maintenance Cost Design
All daily service points (oil filters, fuel filters, radiators) are centrally arranged on one side for ground-level inspection without climbing. Large opening side covers simplify component overhaul, extending service intervals of consumables and greatly reducing downtime.
