In order to ensure ecological transport without failure requirements for the transport of bulk materials by continuous conveyor systems, careful attention should be given to the proper shape of the conveyor belt which is provided by positioning the idler rolls in the idler housing of the pipe conveyor. This paper presents the research on idler housing contact forces (CF) at the crosssection of the loaded conveyor belt filled up to 37.5% and 75%, resulting in a multiple linear regression model in the form: CF = beta(0) + beta 1TF + beta M-2 + epsilon, where TF is the tension force and M is the material filling volume. Based on it, the relative changes of the contact forces were subsequently processed. From the analysis obtained, the position of the most suitable placement of the strain gauge contact force sensors on the idler rolls is proposed, in view of the timely detection of the warning values for failure analysis.
