Modelling of Dynamic Behavior and Control of Truck Cranes : Modelling of Dynamic Behavior of Truck Cranes with Hydraulic System in Elevating Operation

Abstract

This paper is concerned with the modelling of dynamic behavior of hydraulic truck cranes in elevating operation. It is important to analyze the dynamics of hydraulic and mechanical systems to control swaying motion of a suspended load in elevating operation. The booms of the truck crane and a suspended load are approximately expressed by lumped-mass models, and the mechanical system is combined with the hydraulic system containing an elevating cylinder, a hydraulic pump, a counter balance valve, an operated valve, and pipe lines. The dynamic behavior of the crane model in elevating operation is simulated and compared with experimental results.
