Conveying system
for fast supply of an assembly line
Project describtion

The conveyor system built by KRAUS is used for the fast and simple supply of an assembly line.
The main focus was on the ergonomic and safe provision of parts using metal boxes.
The swivel mechanism for the first box has been designed in such a way that the full box swivels gently downwards and only reaches the initial position again when
