In the high-stakes realm of industrial logistics and infrastructure development, the Dongfeng K5 12-ton crane emerges as a technological tour de force—engineered to seamlessly blend brute force, hydraulic precision, and operational intelligence. crane Designed for professionals who demand uncompromising performance in construction, energy, and logistics sectors, this crane integrates a Yuchai 270HP powertrain, Weishen 5-section telescopic crane, and an 8.5m modular cargo box, delivering a unified solution for heavy lifting, transport, and maneuverability. With a focus on safety, efficiency, crane and global adaptability, the Dongfeng K5 sets a new benchmark for heavy-duty cranes in challenging environmentscrane.
At its mechanical core, Cranethe Dongfeng K5 features a Yuchai 270-horsepower turbo-diesel engine—engineered for relentless torque delivery (960Nm) across all terrains. The 6x4 drivetrain, Crane with electronically controlled differential locks, channels power to four driven wheels, providing 30% better traction on mud/ice compared to standard 6x2 configurations. Crane This ensures stable movement under full load (25,000kg GVW), critical for off-road job sites in mining, forestry, or rural infrastructure projects Crane.
The engine’s common-rail injection system (2,000 bar pressure) optimizes combustion, achieving 18% better fuel efficiency (38L/100km) than legacy designs, Crane while meeting Euro V/China VI emissions via SCR+DPF technology. Paired with a 10-speed Fast Gear transmission (synchronized helical gears),crane it enables seamless shifts between low-range torque (for precise 0.5m/s lifting speed) and high-range cruising (85km/h), reducing driver fatigue by 40% during multi-site operations crane.
The crane’s centerpiece is its Weishen 12-ton hydraulic crane—engineered for maximum versatility with a 19.5m working radius and 21.5m lifting height, ideal for high-rise concrete placement, Crane industrial turbine installation, or port logistics. The 5-section arm, constructed from Q345B high-strength steel (yield strength 345MPa),crane achieves a 25% weight reduction over conventional carbon steel, Crane enabling faster extension (65 seconds full outreach) without compromising load-bearing integritycrane.
Powered by a dual-pump hydraulic system (45cc main pump + 30cc auxiliary pump), the crane supports simultaneous operations—hoisting, slewing (360° continuous rotation), and luffing—with zero power lag. crane This design boosts productivity by 22%, crane as demonstrated in a Shanghai metro project where the K5 completed 20% more lifts per day than single-pump competitors.crane The (dual-stage front outriggers) with a 7.6m span increase lateral stability by 40%, crane ensuring safe operation at maximum load/radius (tested to 1.5x rated capacity per ASME B30.5 standards Crane).
Complementing its lifting prowess, the Dongfeng K5 features an 8.5m cargo box crafted from NM400 wear-resistant steel (hardness ≥400HB),crane capable of carrying 8 tons of payload alongside the crane’s 12-ton capacity. The box’s 12mm anti-slip floor and 8 x 2.5-ton tie-down points secure steel beams, machinery, Crane or bulk materials, while modular upgrades like hydraulic tailgates (2-minute auto-load/unload) or tarpaulin systems (IP65 weather protection) adapt to specialized needs Crane.
In real-world use, this dual functionality reduces fleet size by 25%: a Texas wind farm operator reported eliminating three support trucks, cutting logistics costs by $20,000/month while accelerating turbine component delivery crane.
The deluxe 4-point air-suspended cab prioritizes operator well-being, with an ergonomic seat (12-way electric adjustment, ISO 5982-compliant lumbar support) that reduces whole-body vibration by 60% on rough terrain. Climate control maintains 22°C ±1° cabin temperature across -40°C (Russia) to +55°C (Saudi Arabia) environments, while the (one-touch top-mounted start) system minimizes setup time Crane.
The multi-function control panel integrates proportional joysticks for smooth hoist (0.3m/s minimum speed) and slew (2°/s precision), alongside a 12-inch LCD displaying real-time data:
Load Moment Indicator (LMI): Monitors boom angle (±0.5° accuracy), load weight (via strain gauges), and stability margin (calculated every 0.1 seconds) Crane.
Crane-Mounted LED Worklights: 8x 6000K lights (50,000 lumen total) illuminate the work area for nighttime operations, compliant with OSHA 1910.176 lighting standards Crane.
The Dongfeng K5 incorporates redundant safety systems to protect operators, cargo, and surrounding environments:
Vehicle-Level: ABS/EBD braking (12% shorter stopping distance in rain), blind-spot radar (8m detection), and 360° camera with 180° rear-view assist Crane.
Crane-Level:
Overload Protection: Shuts down hydraulics in 0.15 seconds via pressure sensors.
Outrigger Interlock: Prevents lifting until all four stabilizers (front 7.6m + rear 6.8m span) are locked crane.
Emergency Stop: Dual panels (cab + crane console) cut all hydraulic power in 0.5 seconds.
Compliance: Certified to EU Machinery Directive 2006/42/EC (safety class PLd) and US OSHA 1910.180, with a 1.5x safety factor on all load-bearing components Crane.
The K5’s 308mm triple-layer chassis beam (hot-rolled quenched steel) withstands 25% more torsional stress (5,000Nm) than standard designs, proven in 10,000-hour fatigue tests. CraneThe hydraulic system features self-cleaning spin-on filters (β10(c) ≥ 200 efficiency), extending oil life to 3,000 hours—50% longer than industry norms. Exterior protection includes a 5-layer paint system (zinc primer + epoxy intermediate + polyurethane topcoat), resisting salt spray (1,000 hours ASTM B117) and UV degradation (QUV 5,000 hours).
