UNDERSLUNG WINCH AND SHEAVE STRUCTURE FOR TELESCOPIC BOOM ASSEMBLY

摘要

Winch and loadline support structure for a utility vehicle provided with a turret thereon mounting a telescopic, extensible boom assembly having a base boom element, and end boom element of insulating material and at least one intermediate boom element. The winch is carried by an intermediate boom element at the outer end thereof in underslung relationship thereto and the support for the winch loadline is mounted on the outer extremity of the end boom element in generally underslung relationship thereto whereby the end boom element may be used in its extended position while the winch remains spaced therefrom toward the turret of the vehicle. As a result, the intermediate winch carrying boom element may be moved in and out without changing the length of the loadline while it is in use. Boom tip members carrying the load line support have outer curved end margins which describe the involute of a circle to facilitate use of the boom tip in handling poles held thereagainst.
