The analysis of stresses in the main beams of the bridge well crane is carried out in the work. Different types of load are considered: lifting with a pickup, and also loading on a bar from the side The stresses that occur in these cases are determined experimentally, theoretically, and with the help of software. Investigations of the stress state of box beams of cranes with rigid suspension by different methods indicate the reliability of the methods.
