In embodiments of the present invention, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
Fig. 1 shows a block diagram of a control apparatus for a crane according to one embodiment of the present invention. As shown in fig. 1, an embodiment of the present invention provides a control apparatus for a crane, which may be any type of crane, such as an automobile crane, a tire crane, a railway track crane, a crawler crane, a tower crane, a gantry crane, and the like.

Fig. 2(c) shows a schematic diagram of the module for adjusting the opening degree of the simulated handle for the amplitude-varying lifting operation and the amplitude-varying lowering operation, and as shown in fig. 2(c), the opening degree of the simulated handle for the amplitude-varying lifting operation is adjusted to be 60% or the opening degree of the simulated handle for the touch amplitude-varying lowering operation is adjusted to be 40% through touch of the touch display screen, and the touch adjustment for the amplitude-varying lifting operation and the amplitude-varying lowering operation is in an interlocking state, that is, only one direction can be adjusted. Fig. 2(d) shows a schematic diagram of the module for adjusting the simulated handle opening for the main hoisting operation and the main hoisting operation, the simulated handle opening for the main hoisting operation can be adjusted to 80% or 20% by touching the touch display screen, and the touch adjustment for the main hoisting operation and the main hoisting operation is in an interlocking state, that is, the adjustment in one direction can only be performed. Fig. 2(e) shows a schematic diagram of the module for adjusting the opening degree of the analog handle for the secondary winding and raising operation and the secondary winding and lowering operation, the opening degree of the analog handle for the secondary winding and raising operation is adjusted to be 90% or 10% through touch of the touch display screen, and the touch adjustment for the secondary winding and raising operation and the secondary winding and lowering operation is in an interlocking state, that is, adjustment in only one direction can be performed. The above listed 50%, 70%, 30%, 60%, 40%, 80%, 20%, 90% and 10% are only for illustration and are not intended to limit the embodiments of the present invention.
Furthermore, the opening degree module of the simulation handle can be finely adjusted. The touch display screen can also be used for displaying a second preset number of second adjusting small blocks, which are equally divided into the adjusting range corresponding to the first adjusting small block, aiming at the first adjusting module when the first adjusting module is selected.

Taking the left-hand swing operation as an example, fig. 3 shows a schematic diagram of performing fine adjustment on the simulated handle opening degree adjustment module. As shown in fig. 3, if 0 to 10% of the first adjustment small blocks in the analog handle opening degree adjustment module corresponding to the left swing operation are selected, 10 second adjustment small blocks are displayed for the first adjustment small blocks, and the operator can complete fine adjustment of the analog handle opening degree of the left swing operation by selecting the second adjustment small blocks, and the left swing opening degree selected by the operator in fig. 3 is 5%.
Taking a left-hand swing operation or a right-hand swing operation as an example, fig. 4 shows a schematic view of a control device for a crane according to an embodiment of the present invention.
