ROLLER QUICK CHANGE SYSTEM
change roller in 10 minutes, resume production in 30 minutes
when changing different sizes, the middle stands with universal coupling system move backwards and release automatically from the upper and lower horizontal shafts, which is driven by motor or hydraulic system.
For small and middle size machines, lift the whole platform with horizontal & vertical stands and rollers away from the machine base, then lift another same platform with the required pipe roller installed off-line to the machine base, the middle stands with universal coupling system move forward and automatically combine the upper and lower horizontal shafts, driven by motor or hydraulic system.
For big size machines, the upper covers of horizontal stands are designed openable from side, to lift out the shafts with rollers and then lift in those shafts with required rollers installed off-line. Then the opened cover is closed and the middle stands with universal coupling system move forward and automatically combine the upper and lower horizontal shafts, driven by motor or hydraulic system.
