ーン。It is equipped with a telescoping boom consisting of a base end boom, an intermediate boom, and a tip boom, and a compression column type jib that is extended and retracted from the telescoping boom, and this jib has bifurcated jib feet on both sides of the base end. In a hydraulic truck crane, the tip boom of the telescopic boom is provided with jib foot pins for extending the fixed jib, which can be engaged with the jib foot when the telescopic boom is contracted, on both left and right sides of the boom point sheave block. The boom is equipped with a bracket that is removably attached to the tip of the intermediate boom, and this bracket is provided with a jib foot pin for extending the movable jib at the tip of the boom. A hydraulic truck crane characterized by being configured to match the position of a jib foot pin for extending a fixed jib in a retracted state.
