Abstract (en)
A control system is provided for construction cranes comprising a crane mast and a swingable working arm. The control system comprises a movable suspension device (72) for suspending a vertically liftable operator lift. An angle measuring device measures an angular deviation of a top portion of the crane mast and provides a control signal to an actuator based on the measured deviation. The actuator is adapted to move the suspension device in response to said control signal along a guide for compensating for the measured deviation. Also provided are an elevating system, a construction crane (10) and a control method.
