The Dooxin DX140LCR 15-ton zero-tail crawler excavator is engineered for high efficiency and versatility in construction, excavation, road work and confined-space operations. Compliant with Stage Ⅲ emission standards, it combines a robust Cummins engine, advanced e-EPOS hydraulic system and durable undercarriage, delivering unbeatable performance, fuel efficiency and maneuverability for all heavy-duty tasks.
Core Power: Cummins Diesel Engine
Powered by a 4-cylinder Cummins 4-cycle water-cooled diesel engine (3409 cm³ displacement), the DX140LCR features turbocharging, DOC/SCR/DPF aftertreatment (no EGR) and electronic controls for low emissions and optimal power:
- Rated power: 86 kW (115 hp) @ 2000 rpm (SAE J1995)
- Max torque: 46.9 kgf·m @ 1400 rpm for strong low-speed performance
- Electrical system: 24V/5 kW starter, 2×12V 100Ah batteries, 24V 100A alternator for reliable startup
- Idle speed adjustability (950-2000 rpm) and high-pressure fuel injectors boost fuel efficiency across all operations.
Advanced Hydraulic System & Precision Control
The excavator’s e-EPOS (Electronic Power Optimising System) syncs engine and hydraulics for minimal fuel use and maximum efficiency, with key features:
- Twin variable displacement axial piston pumps (2×114.3 l/min @2000 rpm) and 30 l/min pilot gear pump
- 4 operating & 4 power modes, auto-deceleration and cross-sensing pump system for customized performance
- High-strength hydraulic cylinders with shock-absorbing mechanisms (boom/arm/bucket) for extended life and smooth operation
- Precision relief valve settings (Implement:330 kgf/cm²; Travel:350 kgf/cm²; Swing:275 kgf/cm²) for safe, controlled power.
Zero-Tail Swing & Robust Undercarriage
The 1525 mm zero-tail swing radius enables effortless operation in tight urban and confined job sites, paired with a heavy-duty undercarriage built for durability and traction:
- Track configuration: 1 upper/7 lower rollers, 46 links/shoes per side (171.45 mm pitch)
- Multiple track options: 500/600/700 mm induction-hardened triple grouser steel shoes or 500 mm rubber road liners (ground pressure: 0.341-0.465 kgf/cm²)
- Lifetime-lubricated track rollers, floating-seal idlers/sprockets and heat-treated pins for low maintenance
- Hydraulic track adjuster with shock absorption; max traction 15.2 t, 35° (70%) gradeability and 2.9-4.7 km/h travel speeds.
Superior Swing & Lifting Performance
Designed for efficient material handling and digging, the swing mechanism and lifting system deliver industry-leading performance:
- Axial piston motor + 2-stage planetary reduction gear (oil-bathed) for smooth rotation
- Max swing speed:10.13 rpm; Max swing torque:4888 kgf·m for precise positioning
- ISO 10567:2007(E) compliant lifting capacity (up to 10.46 t at -1.5 m reach) with mono/articulated boom options (4.6 m/4.98 m)
- 0.51 m³ bucket capacity, max digging depth 5985 mm and max digging height 9470 mm for exceptional working range.
Comfortable & Safe Operator Cab
The DX140LCR prioritizes operator comfort and safety for long work hours:
- Integrated air-conditioning/heating with pressurized, filtered air distribution
- Heated air suspension seat (adjustable independently from joystick console) with seat belt
- Ultra-low noise: 72 dB(A) operator sound pressure level, 98 dB(A) measured sound power level
- Spacious cab with 360° visibility for safe operation in confined spaces.
Key Specs & Fluid Capacities
- Machine weight: 15.0-15.6 t (per track shoe)
- Fluid capacities: 208 L fuel tank, 128 L hydraulic oil tank, 25 L AdBlue tank
- High-strength structural components and all-welded undercarriage for stress resistance and long service life.
The Dooxin DX140LCR is the ultimate all-in-one solution for contractors seeking a powerful, maneuverable and reliable excavator that excels in every job site condition—from urban construction to industrial excavation.
