Product Advantage
Versatile Lifting Capacity
Models range from 3t to 8t lifting capacity with maximum working radii from 10.5m to 18m and maximum lift heights up to 21m, capable of handling steel structures, industrial machinery, HVAC units, transformers, and modular construction components.
Advanced Hydraulic & Boom System
Featuring multi-section telescopic booms, smooth boom extension/retraction, 360° continuous rotation, and precise hoisting control, ensuring stable, accurate, and safe lifting even in constrained spaces.
Compact & All-Terrain Mobility
Crawler tracks with hydraulic drive allow zero-turn mobility, climbing angles up to 25°, and speeds up to 2.5 km/h, making these cranes ideal for indoor, urban, and off-road construction sites.
Dual Power & Remote Options
Equipped with diesel engines and electric motors, starting in temperatures from -5°C to 40°C, and optional remote control operation, giving flexibility for indoor lifts, energy-sensitive areas, and urban deployment.
Customizable Outriggers & Safety Features
Hydraulically assisted outriggers extend the base footprint for maximum stability. Optional moment-limiting devices, remote control, work platforms, and hydraulic jibs enhance safety and operational efficiency compared to standard mini cranes.
