SOLUTION: A telescopic boom 25 installed on a frame 22 is freely extendible in a vertical direction, a cable support 10 is provided at the tip portion of this telescopic boom 25 thereby forming an overhead cable holder. This cable support 10 is extended in a vertical direction, has a hollow through-hole space and formed to a cylindrical shape. A cable 27 is supported by inserting it through this hollow space, and the extending direction of the cable is guided by sliding and contacting along the inner peripheral surface of the hollow space. Here, the inner peripheral surface near the upper portion of the hollow space of the cable supporter 10 is formed smoothly wider outwardly.</p> |
