Suspension device for extension jib

Abstract

This item is a lifting device for an extension jib, which is used when the extension jib of a boom device equipped with a boom and an extension jib is stored below the boom. When in use, the extension jib is suspended from the boom by connecting the jib-side suspension part of the extension jib to the suspension bracket of the extension jib suspension device, as shown in Reference Figure 1. Furthermore, as shown in Reference Figure 2, the suspension bracket to which the jib-side suspension part is connected is moved along the length of the boom, thereby moving the extension jib along the length of the boom.
