Stabilizing base for truck-mounted mobile cranes for 360 DEG work sites wherein, instead of placing the front supports perpendicularly to the longitudinal axis of the vehicle (parallel to the rear beams as indicated), they are oriented towards the truck cabin thereby forming an acute angle so that, when the front beams are extended, the support points of the vertical cylinders are displaced towards the front part of the vehicle thereby obtaining a major longitudinal separation between the front and rear supports and consequently an appropriate stability base. Thus, the center of gravity of the loaded crane with its boom oriented forwards is within the support base formed by the four stabilizing supports.
