Claims

[Claims for Utility Model Registration] (1) Crane boom length detection sensor; Crane boom angle detection sensor; Storage device for inputting and storing the crane's unique constant values and overhead height limit values in advance; Crane boom length The boom height is determined by processing the crane boom length detected by the detection sensor, the crane boom angle detected by the crane angle detection sensor, and the unique constant value of the crane stored in the storage device. A computing device that performs this in real time; Compares the real-time boom height calculated by the computing device with the overhead height limit stored in the storage device, and when the boom height exceeds the overhead height limit. 1. A crane boom height limit warning device comprising: a limit device that outputs an output; a warning device that issues a warning upon receiving the output from a control device; (2) The crane boom height limit warning device according to claim 1, wherein the crane height produced by the calculation device is digitally displayed in real time on a display window. (3) The crane boom length detection sensor and the crane boom angle detection sensor are housed in a sensor box and are detachably attached to the crane boom using a magnetic stand. Crane boom height limit warning device according to item 2.
