Abstract:

The aim of this paper is to design an alarm system to prevent the overturning of truck cranes under condition of ground failure. The conditions under which truck cranes tip are first formulated against the cases in which the ground is rigid enough and in which the ground might possibly fail. The ground response under the outrigger pontoon of a truck crane is expressed by a kind of Weibul distribution curve and the degree of danger is formulated by the ratio of the loading stress to the estimated bearing capacity at yield obtained from numerical iteration. An alarm system based on the degree of danger is finally proposed.
