  • the outrigger housings are located at the positions inside toward the center of the body from each of the vertical lines tangential to the perimeter of the forefront wheel and rear most wheel at the front end side and rear end side thereof respectively, so in the case of increasing the distance between the front and rear axle supporters to increase the span to support the increased moment due to increased capacity of the crane, the distance between the front and rear axle supporters, i.e. the wheel base can be increased with minimal increase in the length of the vehicle.
  • the stability of the platform car is secured with minimal increase in the length of vehicle compared with the conventional structure when to increase the capacity of the crane mounted on the platform car.
  • FIG. 1 is a side view showing the platform car and outriggers of the mobile harbor crane according to the present invention and FIG.2 is a sectional view along line A-A in FIG.1 .
  • reference numeral 1 is the body frame of a platform car
  • 2 is a supporter provided on the center part of the body frame 1 for mounting a crane (not shown in the drawing)
  • 3 shows the center axis of the platform car, which is the rotation axis of the crane.
  • Reference numeral 7 are front and rear wheels, 10 are hydraulically steering type axle supporters having a plurality of axles 10A supporting left and right wheels and driving means thereof.
  • the hydraulically steering type axle 10 is public known and detailed explanation of its structure is omitted.
  • Reference numeral 04 are brackets fixed to the underside of said body frame 1 at the front and rear parts.
  • Reference numeral 5 are supporting arms, the center part of each of which is supported for rotation by said bracket 04 so that the arms 5 can swing parallel to a longitudinal vertical plane, which is a so-called balance-beam structure.
  • Reference numeral 06 are second brackets, each of which is supported for rotation at an end side of each supporting arm 5.
  • Reference numeral 6 are second supporting arms, the center part of each of which is supported for rotation at each second bracket 06 so that each second supporting arm 6 can swing parallel to a longitudinal vertical plane, which similarly constitutes a balance-beam structure just like said supporting arms 5.
