Abstract

A steering system is capable of steering a plurality of conveyor vehicles connected together in the form of a train. The vehicle has a first pair of wheels which can be steered by an operator as the train moves. There are further pairs of steerable wheels connected to the second and subsequent vehicles in the train and supporting same. There are hydraulic cylinders for steering each of the pairs of steerable wheels on the second and subsequent vehicles and a control mechanism for controlling these cylinders in order to set the steering angle of each further pair. This control mechanism includes means for determining the current steering angle of the first pair of wheels and generating an electrical signal indicative thereof and means for storing a series of these electrical signals as the train is travelling. Further means determine the amount of time the wheels in the train have been travelling and there is a calculator for determining the location of each of the further pairs of wheels on the basis of the determined travel time. A second electrical signal is generated for each further pairs of wheels in order to control its respective hydraulic cylinder and thereby set the steering angle of each pair at the same steering angle that the first pair of wheels had when they were at that location.
