装置。An elevation angle detection mechanism that electrically detects the elevation angle of each crane and a turning angle of each crane in two cranes that are arranged adjacent to each other and whose workable ranges partially overlap each other to form a work interference range. A swing angle detection mechanism that electrically detects each angle, and an output signal from the elevation angle detection mechanism and the swing angle detection mechanism, and when one of the cranes enters the work interference range, the crane enters the work interference range. A collision prevention device for two cranes, comprising a control mechanism for controlling the other crane to prevent the other crane from entering.
