<p>PROBLEM TO BE SOLVED: To provide a display means allowing an operator to be able to intuitively and simultaneously catch the final state of a telescoping boom and the present states of the telescoping boom and a telescoping cylinder in a telescoping process by improving the display method of a telescoping-related information display means in a control device of a telescoping mechanism. SOLUTION: In this control device of the telescoping mechanism for drivingly telescoping boom stages forming a multi-stage telescoping boom 10 one by one by a single telescoping cylinder 1, the telescoping-related information display means 70 schematically displays the telescoping boom in the final boom state inputted by a final boom state input means 63 on the display screen thereof, and, simultaneously, schematically displays the telescoping boom and the telescoping cylinder in the telescoping process detected by a telescoping state detection means 130.</p> |
