変チルト装置。A top boom 13 located at the tip of the boom, and a tongue boom 1 located on the boom base end side from the top boom 13.
The auxiliary jib 2 is attached to the tip 13a of the top boom 13 of the telescopic boom 1, which looks over the second boom 12 that telescopically supports the second boom 12, which supports the second boom 12 that telescopically supports the second boom 12. This is a variable tilt device for an auxiliary jib in a telescopic boom with an auxiliary jib, which is supported so as to be able to rise and fall freely by an appropriate tension member 6 such as a tension rope stretched between the telescopic booms 1. The end portion 6a' on the side of the telescopic boom 1 is attached to the top boom L: 13 side so as to be movable in the boom extension/contraction direction by a certain width, and the top boom 13 is made to protrude from the second boom 12 by a certain amount or more. An appropriate stopper 4 formed on the second boom 12 side by
7 in the boom extension direction to engage with the stopper 47
The auxiliary telescopic boom with an auxiliary jib is supported by an appropriate tension member support device 40 configured to be moved toward the proximal end of the top boom 13 as the top boom 13 extends. Variable tilt device for jib.
