The patent application (Publication Number: US20240034602A1) describes a convertible, fast-erecting tower crane with innovative features aimed at enhancing safety and stability during operation. The crane controller includes a monitoring device that can detect wind resistance parameters and adjust the load limit accordingly to ensure safe operation. This monitoring device is also capable of changing load limits based on the position of components relevant to wind resistance on the crane, such as height and distance from the tilt axis.

Furthermore, the crane includes a position-variable control and staff cabin, along with a position determiner to determine the cabin's position. The monitoring device can adjust load limits based on the cabin's height, ensuring optimal safety during crane operation. Additionally, the patent application details the use of an accessory mounting surface determiner to detect accessory mounting surfaces on the crane, allowing for load limit adjustments based on the position and inclination of these surfaces. Overall, the crane's monitoring device operates semi-automatically or fully automatically, depending on the signal from the wind resistance detection unit, to ensure safe and efficient crane operation.
