    • PROBLEM TO BE SOLVED: To provide a telescopic jib for a movable crane provided with a fixing device having high structural strength stably. SOLUTION: This telescopic jib for the movable crane provided with the fixing device is constituted in such a way that (a) a fixing pin 10 is guided onto an inner side of an inner side expansion and contraction part 2 and is energized onto an outer side by a spring 14 and (b) an outer end part 12 of the fixing pin can be engaged with a receiving part provided in an outer side expansion and contraction part 1 surrounding the inner side expansion and contraction part 2. (c) Releasing devices 20 to 24 are arranged to engage with an inner end part of the fixing pin to release a fixing part against energizing force of the spring, (d) at least two fixing pins in each fixing unit are arranged in the inner side expansion and contraction part and can be engaged with two receiving parts arranged by opposing to a central part of a vertical side web of the outer side expansion and contraction part, and (e) the releasing devices have a hydraulic operation cylinder 20 arranged on a head part of a cylinder 30 on a piston 40 and a cylinder unit 30 and extending in parallel with a shaft in the longitudinal direction.

    • PROBLEM TO BE SOLVED: To provide the configuration of a chassis easily convertible or configurable for use on the U.S. market, the European markets, and other markets.
      SOLUTION: A mobile crane includes the chassis having first connection features located on a rear end thereof. An outrigger includes second connection features for mating with the first connection features. A tag axle assembly includes third connection features for mating with the first connection features. The first connection features may accept either the second connection features or the third connection features, so that the mobile crane may be selectively configured for highway travel and selectively configured for working operation. One or more axles of the mobile crane may be elevated when the tag axle assembly is connected to the first connection feature. Further, a wheeled boom dolly may be employed to share weight with the chassis when the mobile crane is traveling.
