Definitions

  • the invention relates to an outrigger assembly comprising an outrigger frame and an outrigger beam movable in a horizontal extension direction with respect to the outrigger frame in between a retracted position and an extended position.
  • the outrigger beam is located inside the outrigger frame in the retracted position and is extended from the outrigger frame in the extended position.
  • the outrigger beam has a proximal end and a distal end with respect to the outrigger frame in the extended position of the outrigger beam.
  • the outrigger assembly further comprises an outrigger support coupled to the distal end of the outrigger beam to allow supporting the outrigger assembly in a supporting position of the outrigger support on a supporting surface in the extended position of the outrigger beam.
  • the invention further relates to any vehicle, such as a mobile crane, provided with such an outrigger assembly with horizontally extendable outrigger beams.
  • the outrigger beams are extended from the outrigger frame and the vehicle, and the outrigger supports are lowered onto the ground at a location where a heavy load is to be handled.
  • the extended outrigger beams provide a much higher stability to the mobile crane and higher loads can be handled with increasing width of the extended outrigger assembly.
  • the width of the extended outrigger assembly is determined by the length of the outrigger beams, while the length of the outrigger beams is limited by the width of the vehicle in which the outrigger beams are housed in their retracted position.
  • Present vehicles with outrigger assemblies, especially mobile cranes have reached the limit of the maximum width of the extended outrigger assembly that can be achieved. A further increased width, however, would increase stability or the maximum load or load moment (load at a certain radius) that can be handled.
  • US 3,756,424 discloses a mobile crane having an outrigger assembly of which outrigger beams can be extended from an outrigger frame to provide an extended position of the outrigger beams and a supporting position of the outrigger assembly. In the supporting position, an end of the outrigger beam being supported on the ground induces a first torque that is balanced by a second torque provided by the outrigger beam extending over a certain length still within the outrigger frame of the outrigger assembly.
  • the extension length of the outrigger beam from the outrigger frame is limited by the total length of the outrigger beam, which is limited by the width of the mobile crane, and the length of the outrigger beam remaining within the outrigger frame to induce the second torque. This document discloses the preamble of claim 1.

  • the projection at the first end 501 of the slider element can slide along the slot between first and second slot ends 251, 252.
  • Figure 4D of the extended position of the outrigger beam shows that the projection at the first end 501 of the slider element cooperates with the first slot end 251.
  • a projection at the second end 502 of the slider element 500 cooperates with a first stop 111 in the bottom region of the outrigger frame 100.

  • the outrigger frame causes a seventh vertical force Fv7 acting downwards at a ninth location L9 on the outrigger beam.
  • the eighth and ninth locations L8, L9 are actually the same, or virtually the same, in the embodiment shown, as there is a limited contact area between the upper side of the outrigger beam and the outrigger frame. Generally, the eighth and ninth locations L8, L9 need not be the same. Further, the outrigger frame causes an eighth vertical force Fv8 acting upwards at a tenth location L10 on the outrigger beam.
