End beam of the support crane g/p 3-5T (drive Italy)

The end beam of the support crane (trolley movement) is used as the main set of mechanisms for the movement of the load-lifting crane. It is made in the form of a metal structure made of profile metal of the channel type to which, with the help of bolts, the movement mechanism(drive) is attached. Movement carts have 2 wheels of plumage and transmission of torque, which increases the reliability of the design, the wheels themselves have an edge that allows you to Orient the crane along the crane path. At the ends of the carts there are colliders that do not allow the crane to move off the tracks and fall if the tracks are uneven or poorly installed. The drive in the form of an Italian worm gear reliably ensures the transmission of torque to the wheel, the smoothness of the worm gear gives the movement of the crane a soft stroke, movement without shocks and self-stop. An ordinary motor is easily controlled by a frequency Converter.
