Equipment to turn around pieces 360 degrees. They have two parallel columns, with motorized plates which rotate the part.
They can have fixed or variable elevation (with adjustment pins or motorized), great for long devices such as frames or railroad cars.
Usually, only one of the plates is motorized for the spin while the other one is used as stabilizer. However, for very big applications both can have coordinated mechanization.
The distance between the head and the tail can be fixed or variable, although they have to be very well aligned. In case variable distance is required, rails are recommended.
Their capacities are from 3 up to 500 tons, custom made.
