Study on Static Stability of a Truck Crane Carrier

Abstract

In this paper are analyzed the static stability of a truck crane carrier and the reaction force of outriggers against the ground, taking into account the elastic deformation of the frame and outriggers. From this analysis, simple practical formulas of a load acting on the outrigger float are obtained, and are compared with the conventional formulas. Here are also studied the effects of dimensions and specifications, rigidity of the frame and the outriggers, rotation angle of the upper machine, angle of inclination of the carrier, unbalanced height of the outriggers and the ground contact conditions on the static stability and the reaction force of the outriggers.
