Specification

Key Configurations

Total weight: 39000kg (including secondary weight)
Hydraulic System: Precision-controlled pumps and valves for smooth operation
Engine: Yuchai YCK08330 - 61 (National Ⅵ)
Max speed:  90km/h
Rated lifting capacity:  50t
Longest main boom:45m

Power and Performance
At its core, the STC500 is driven by a Yuchai YCK08330 - 61 engine, compliant with National Ⅵ emissions. With 243kW of max power at 2200rpm and 1350N·m of torque across 1200–1700rpm, it delivers relentless force for heavy loads. This engine ensures smooth acceleration, even under peak demand, minimizing idle time and maximizing productivity.
Lifting Capability
Boasting a 50t rated lifting capacity, the STC500 tackles large - scale tasks with ease. Its lifting moment reaches 1644kNm (basic boom) and 1098kNm (longest main boom), enabling efficient hoisting of materials, equipment, or precast structures. The boom system offers exceptional flexibility: a 45m single main boom or a 61m combination with a secondary boom. This adaptability suits diverse scenarios, from high - rise construction to wind turbine installation.
Mobility and Efficiency
The STC500 stands out for its agility. A 90km/h max speed allows rapid transit between sites, cutting travel time. Its 19° approach angle, 12.5° departure angle, and 45% gradeability let it navigate rough terrain, slopes, and narrow roads. With a 37L/100km fuel consumption, it balances power and cost - effectiveness, ideal for long - term projects.
Operational Precision
Advanced winch and boom systems boost efficiency. Both main and auxiliary winches reach 140m/min (single rope), speeding up load handling. Boom extension/retraction takes just 100/120 seconds, and full boom lift cycles finish in 50/60 seconds. A 0–2.5r/min rotating speed enables precise load positioning, crucial for delicate placements in tight spaces.
Durability and Stability
Weighing 39000kg, the STC500 distributes loads evenly: 13000kg on the front two axles and 26000kg on the rear two. This balanced design ensures stability during travel and lifting. Its compact dimensions (13960×2650×3700mm) enhance maneuverability in urban or confined sites without sacrificing structural strength.
Safety and Comfort
Safety is integrated into every aspect. The 7.5×4.05m leg span (basic boom) provides a wide, stable base. Hydraulic systems and load - sensing tech prevent overloading. The operator cabin offers excellent visibility and ergonomic controls, reducing fatigue during long shifts.
