In this paper we present calculations of the dynamic loads in the rope and the bridge crane in the application of an improved fork. Improved fork has lateral restraints, which move with the help of a hydraulic system, which led to an increase in mass capture. The calculation is performed to check the possibility of an improved fork. The calculation was performed for a gradual deceleration sinking of the cargo at the joint work of the lift mechanism and an elastic bridge. The calculation showed that the maximum loads in the application of forks in the rope is equal to 15.6 kN, which does not exceed the limit values of 54.9 kN and the maximum loads using a special fork in the bridge are equal to 41.7 kN, which does not exceed the limit value of 50 kN.
