Abstract: The article investigates the loads and forces arising in the bearing elements of a special mast of a pantograph-type
hoist. To solve applied problems of mechanics, the methods of cutting out nodes and finite elements are used. A flat geometric design
diagram of pantograph-type lift elements has been developed and described by equations. A physical and mathematical model of the
control object in the form of load-bearing elements of a pantograph-type elevator has been developed for analytical study of the
stress-strain state and determination of the controlled parameters of the test product. The results of the work are applicable for
planning tests of the investigated hoist, monitoring and analyzing the results of the experiment.
Index terms: pantograph lift, stress-strain state, physical and mathematical model.
