Telescopic Crawler Crane
Crawler Crane
Rated Lifting Capacity:50,000kg
Max.Lifting Height:38m
Engine:CUMMINS QSB6.7
Operating Weight:60,000kg
The QUY50 crawler crane is a 50-ton class, fully slewing, truss main boom + optional jib, fully hydraulic crawler crane. Positioned for medium-tonnage heavy-duty lifting and complex terrain/long-distance operations, it features a large lifting height/amplitude, low ground pressure, high safety redundancy, and adaptability to all working conditions. It is a mainstay model for municipal pipelines, petrochemical equipment, steel structures, wind power foundations, wetlands/mountainous/high-altitude environments, and other scenarios. Its performance surpasses the QUY25 across the board, balancing heavy load and flexibility.
Heavy-duty + High-altitude + Long-distance All-rounder: 50-ton rated lifting capacity + 52m main boom + 15m jib, maximum lifting height 60m, working radius 48m, perfectly covering medium-tonnage heavy-duty, high-altitude steel structure, wind power foundation, and long-distance lifting scenarios, with performance far exceeding that of other crawler cranes with telescopic booms of the same tonnage.
Strong terrain adaptability: Wetland-type tracks + low ground pressure + variable gauge + 40% climbing ability, outperforming tire cranes/truck cranes in soft soil/wetlands/mountainous areas/high altitudes, solving the pain points of "cannot enter, cannot stand steadily, cannot climb".
High operating efficiency: Heavy-duty and efficient truss boom + fully hydraulic control + 360° rotation + short-distance self-propelled + gravity lowering, integrating hoisting, relocation and positioning, saving 35%+ man-hours and reducing fuel consumption by 15%+ compared to traditional equipment.
