The VLA is crucial when it comes to single heavy lifts, where absolute accuracy is required, ensuring that no load sway occurs when the cargo is lifted off the ground, even when the crane driver does not have a clear view.
The system is automatically engaged by means of rope inclination sensors fitted to the boom, ensuring that the boom tip is precisely positioned vertically over the load to prevent unwanted lateral movement.
Designed to perform computer assisted synchronous tandem lifts, with one crane operator controlling both cranes, the tandem lift assistant removes the risks experienced in moves involving multiple cranes, such as lateral forces, overturning moments and deviations in crane speed. As a result it is possible to lift up to 400 tonnes.
