Universal Jig Line for Assembly of Railway Car Underframes

This line was designed for assembly of railway car underframes of passenger car types 4440, 4441, 4444, 4447. The jig line is a framework where guides with T-type slots as well locators and clamping elements are fixed. While readjusting of the line for some frame dimension-type locators and clamping elements move along the T-slots. Constituents of a piece are clamped by pneumatic actuators. The use of a pneumatic system ensures a even clamping of all the constituents.
