Embodiment Construction
[0052] In order to improve the accuracy of determining the height of the hoisting hook, further improve the accuracy of the height limit of the hoisting hook, and improve the safety of the tower crane hoisting operation, the embodiment of the present invention provides a hoisting hook of the tower crane A height control method, device, system and a tower crane. In this technical solution, when the weight of the hoisted object and / or the operating position of the luffing trolley are different, the length of the vertical rope of the hoisting wire rope is also different. The detection height, and the length of the vertical rope of the lifting wire rope, the detection height of the lifting hook and the corresponding relationship between the real height of the lifting hook can be used to obtain the real height of the lifting hook. The determination result of the real height of the lifting hook is relatively Accurate, can greatly improve the accuracy of the height limit of the lifti...
