In the article are presented main principles and leads-up to the choice of the general criterion of the main beams’ optimization. The main reasons leading to the destruction of arms include cyclic load causing fatigue phenomena, creep occurrence causing elements deformation beyond a critical state, the constructions’ blistering appearing owing to the metal maturing, corrosion of the main beams’ elements, leading to the loss of their carrying capacity. The general optimization criterion is chosen. The parameters of the main beams’ endurance are defined. The device for the measuring of the size and the character of the vibrations’ decay of the bridge cranes’ main beams is suggested. We have the results of the experimental information, received on the bridge cranes of the different plants. The work directions by the optimization of the constructive parameters of the cranes’ main beams are defined. Into the suggested construction of the span beam are put such statements: high values of the general optimization criterion’s; stiffness of the arm to the reduced weight ratio, possibility of the beam’s creation of the equal resistance, minimization of the local deflection tensions from the load cart on account of the inclined walls’ position. The construction of the patented span beam of the diaphragm construction is observed and described.
