Side angle

plates

Conveyer using for falling compound move to the operator side & side plates support to direct the falling compound in to the bottom conveyer.

Moving to forward & backward


Back Fence

Back fence working as a barrier in back side of the mill. If somebody open the back fence door while operation, quickly mill stopped.

Foot path to cutter & belly bar designs Staretgic Engineering - MH BU

Critical point of the strip cutter



Option 1

- Convenience production - Body bar can be activate 180 degree - Easy for implementation

- Not comply the EN standard - Risk is there

Option 2

- Comply the EN standard

- In convenience production due to frequent stoppage

- Additional ergonomic risks exists - Not convenient to activate Body bar

180 degree - There is a risk of compound entangle

and break the bar

Option 3

- Comply the EN standard

- In convenience production due to frequent stoppage

- Additional ergonomic risks exists - Not convenient to activate Body bar

180 degree - There is a risk of compound entangle

and break the bar
