Definitions

  • the present invention refers to a stabilizing base for truck mounted mobile cranes for 360° work sites.
  • the classic system consists of a pair of frontal beams moving parallel and horizontally in relation to a pair of rear beams. Once the four beams have been extended by means of hydraulic cylinders ( one for each beam) , other cylinders of vertical run installed on each side are the ones which suspend the ensemble of the auto-crane from the ground in order to achieve a mayor stability.
  • the truck- carrier vehicle is usually a special chassis or even a normal truck.
  • the usual difficulty is that the operating zone for the crane is limited to less than 360°, that is to say that on the frontal part of the vehicle, the crane is not stable when carrying loads, due to the cabin's position and other elements of the vehicle and also due to the distribution of the own weights of the truck, considering that the gravity centre of the crane ensemble with nominal loads, remains ahead the frontal stabilizers, that is to say outside the sustaining base y this causes that the stability or effective working area of the crane is reduced from the usual 360° to about 270° approximately.
  • the present invention consists in varying the position of the horizontal beams of the frontal supports in order to reach the 360°.
  • the beams are installed facing the cabin of the truck and constituting an acute angle with the scope that when the frontal beams are extended, the support points of the vertical cylinders move towards the frontal part of the vehicle obtaining a greater longitudinal separation between the frontal and rear and accordingly of the adequate stabilizing base.
  • the gravity centre of the crane with loads and with the boom facing ahead is inside the sustenance base that is performed by the four stabilizer supports.
  • the rear supports (1) are extended as usually, that is, perpendicularly to the longitudinal axis of the vehicle and the front supports (2) are placed in such a way that the axis are moved towards the front part of the truck, delimitating a acute angle (3) in relation with the usual position.
  • the horizontal housings (4) of the expanding beams (1 and 2) are part of the framework. These horizontal extensible beams (1 and 2) are actuated by the hydraulic cylinders (5).
  • the effective support of the crane on the ground is operated by means of shoes (6) over which lay the vertical hydraulic cylinders (7).
  • the distance between the front and rear (A) supports is bigger than the distance (B) that would result with the usual position and the gravity centre (C) is situated inside the sustentation base performed by the four support shoes (AXD).
