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.

For verification of mechanism work with this muff a mathematical model is made. Basic formulas are resulted for determination of loadings and frequency of eigentones of the system with a resilient muff. The results of calculations are resulted for concrete bridge faucet. Calculations are presented as diagrams, showing the change of loading and frequency of eigentones from inflexibility of muff. As a result these calculations bring about a possibility of application of resilient muff in the mechanism of movement of travelling crane.
