Crocodile assembling and tack welding machine
ASSEMBLING EQUIPMENT 
The Crocodile or Clamp type machines can be descried as mobile work centres, which can be moved in or out of a shell for assembly work as required.
The purpose of the Crocodile and Clamp is the multi-directional alignment of shells for tack welding and for welding parts together.
