Lifting Performance and Working Range
Rated Capacity at Defined Radius
The QAY220V delivers a stable 220 tonne lifting capacity across key working radii, enabling efficient handling of steel structures, generators, and transformers. Load charts guide operators to maintain safe configurations while optimizing cycle times.
Boom Extension and Working Radius
With a 66 meter maximum boom length and optional luffing jib, the crane achieves generous working radii for tall structures and complex layouts. Modular boom sections allow fast assembly while maintaining precise alignment and reduced swing time.
Suspension and Hook Height
The maximum suspension length of 63 meters supports deep coverage zones without frequent repositioning. Higher hook height at maximum radius reduces ground-based intervention, improving overall site throughput and crew safety.
Transport and Assembly Efficiency
Sectional Design and Road Permits
Split into manageable transport units, the QAY220V fits standard road limits while preserving high performance. Quick coupling systems minimize downtime during transfer between jobs and support rapid deployment in congested urban areas.
Setup and Stabilization
Outrigger systems and robust crawler chassis enable fast leveling on varied terrain. Automated setup routines assist operators in configuring stabilize forces, reducing preparation time and lowering the risk of uneven settlement.
Digital Control and Safety Systems
Monitoring and Load Management
Integrated sensors and digital interfaces provide real time data on load, radius, and angle. This helps operators stay within rated parameters and supports compliance with project specific lifting plans and regulatory standards.
Operator Assistance and Diagnostics
User friendly controls, clear displays, and proactive diagnostics simplify daily operation and maintenance planning. Remote connectivity options facilitate timely troubleshooting and component management, keeping uptime high across fleets.
Operational Recommendations and Takeaways
- Use load charts to confirm capacity at each radius before lifting.
- Plan modular boom assembly sequence to reduce setup time.
- Leverage digital monitoring for real time safety and efficiency.
- Schedule proactive maintenance to avoid unplanned downtime.
- Train operators on urban deployment and stabilization procedures.
