Projects

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.

Customer/branch: food industry
