Therefore it is necessary so that users of the pipe belt conveyors are able to perform a more detailed investigation and monitoring of these characteristics. Thanks to information concerning the operational characteristics it is possible to analyse durability of the conveyor belt and extent of belt wearing. However, the process of data collection and identi?cation is demanding and expensive on condition that such process would be realised only by means of measuring equipment. Much more effective is obtaining of the needed information using generalized knowledge in the form of graphs. Every operator of the pipe belt conveyor is able to obtain the required information based on known input values using the corresponding graphs. Afterwards, the obtained information can be applied in a real operation. This article deals with determination of the contact force values for a certain type of the conveyor belt. The contact forces can be estimated in the
