The 50 ton mobile crane redefines large-scale construction efficiency, with a maximum lifting capacity of 50 t (at 5m radius) and 43m full-extend boom (7-section Q690 steel boom) for long-reach tasks. Powered by a 250 kW Cummins QSM11 engine (meets Euro 3 emissions standards) and equipped with an 8x4 drive train, it reaches road speeds of 85 km/h for fast job site relocation (e.g., 300km trip completed in ~3.5 hours). The crane’s 42,000 kg operating weight (with standard 12t counterweights) and 6x7.2m outrigger span ensure stability for heavy lifts, while its 5.2m wheelbase and air disc brakes (with ABS) guarantee safe road travel. It includes a remote control system for standalone outrigger setup.
8x4 Drive Train: 8x4 heavy-duty drive train with 4 driving axles, differential lock, and 16.00R25 off-road tires ensures off-road mobility to remote construction sites—such as mountainous wind farm locations, rural highway construction zones, and mining areas with unpaved roads.
Super-Lift System: Hydraulic super-lift system with 10t additional counterweight increases lifting capacity by 30%, allowing the crane to handle 65t loads at 5m radius for heavy machinery installation (e.g., 50t excavators, 60t bulldozers).
Fuel-Efficient Design: Cummins QSM11 engine with electronic fuel injection and eco-mode (reduces engine speed during idle) consumes only 45 L/100 km during road travel—cutting fuel costs for long-distance relocations (e.g., 200km trip uses 90L fuel vs. 120L for comparable cranes).
Quick-Setup Outriggers: 6x7.2m-span hydraulic outriggers with automatic leveling function (±0.5° accuracy) and rubber pads (500mm diameter) deploy in 5 minutes—eliminating manual adjustment and speeding up on-site setup; includes a visual level indicator for operator verification.
Large-scale building foundation construction: Lifting 40t steel reinforcement cages (for concrete piles) and 50t concrete piles (15m length) to build deep foundations for high-rise buildings (20+ stories).
Wind turbine component lifting: Handling 45t nacelles (turbine housings) and 30t rotor blades (60m length) for 2MW wind turbines—positions components at heights up to 80m when paired with a 30m jib.
Heavy machinery transportation and installation: Loading/unloading 50t excavators, 60t wheel loaders, and 40t asphalt pavers onto transport trailers; installing 55t industrial boilers and 50t press machines in factories.
Commercial building steel structure assembly: Lifting 40t steel trusses and 35t roof beams for large-span commercial buildings (e.g., shopping malls, warehouses with 50m span roofs).
Q: What’s the tail swing radius?
A: 4 m tail swing radius allows safe operation near existing structures (e.g., adjacent buildings, power lines, underground pipelines) with minimal clearance requirements—ideal for urban construction sites with space constraints.
Q: How much does it weigh?
A: 42,000 kg operating weight with standard 12t counterweights; additional 18t counterweights can be added (via a separate transport trailer) for heavy-lift tasks, increasing the total operating weight to 60,000 kg and expanding lifting capacity to 65t at 5m radius.
