The stress-strain state of the flat rope of hoisting engine with considering their technical state

摘要

Obtained an analytical dependence for determining the tensile forces acting in cables of the fl at rubberized rope. It takes into account the design of the hoisting engine – the deviations of generating line of the drum from a straight and of the possible break of the cable in rope. A comprehensive account of the impact of various factors on the stress-strain state of the rope allows determining the loss of tractive capacity in operation on the hoisting engine. The results should be taken into account in the design and operation of hoisting and transporting machines with fl at traction bodies.
