Projects

Conveying eqipment for fast supply of an assembly line

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

Adaptation of our conveying elements to on-site conditions

Adaptation of our conveying elements
to on-site conditions
Properties

One example of the flexible adaptation of our conveying elements to on-site conditions at our customers is the mini tapered idler roller curve shown with 2x 90° and gradient, in the form of a helix, as well as straight sections between the curves and as a transfer section to the downstream conveyor belt.

Requirement

The packages from the foiling machine have to be transported between an existing staircase outside the hall into the neighbouring hall and overcome a height difference of 1,000 mm.

The equipment was put into operation exactly on schedule thanks to the exact coordination between all those involved in the projects.
