U Rib assembly machine

U Rib assembly machine

U‑RIB assembly machine is designed to tightly press U‑ribs onto base plates for accurate alignment and gap elimination at mating surfaces. Manual positioning and spot welding can be carried out at joints of six U‑ribs and base plates. It comprises travelling frame, travelling tracks, integrated U‑rib pressing module, hydraulic system and manual welding system.

Product Parameters

1.Introduction for U Rib assembly machine:

This machine is mainly used to press the U-rib firmly onto the base plate, forcing the U-rib to align with the assembly line of the base plate, eliminating the gap at the contact point between the U-rib and the base plate, and performing manual positioning and spot welding at the joint of 6 U-ribs and the base plate.

This machine is composed of a walking frame, a walking track, an overall U-rib pressing module, a hydraulic system, a manual welding system, etc.
