Karl Meyer: emergency stop spotted, service call saved
November 10, 2026

A customer calls because their press is not running. At Karl Meyer Umweltdienste, that often used to mean sending a technician out to take a look. Today all dispatch needs is a glance at the adhoc platform. In a recent case, it already showed that the emergency stop on the press had been pressed before the phone rang. A quick word with the customer was enough.
125 compactors at a glance
Karl Meyer Umweltdienste has fitted 125 compactors with our Packman reporting system. Packman reads the press signals, such as fill level, emergency stop, faults and power, and sends them together with the GPS position to the adhoc smart waste platform.

"The customer called because the press wasn't running. I could see in the system right away that the emergency stop had been pressed. In the past, a technician would have driven out for that. For me, the service calls we save are one of the biggest advantages," says Nils Hinsch, deputy operations manager at Karl Meyer Umweltdienste.
What Packman reports
Besides the emergency stop, Packman picks up the press's pre-full and full signals. From these, the platform works out when the next pickup is due. It also reports general faults, phase sequence errors and whether the press has power at all. With GPS, dispatch sees every press on the map, and geofences assign it to the right customer automatically.
Packman works with compactors of any make and can be retrofitted in a 230 V or 24 V version.
Needless service calls cost money
A pressed emergency stop, an unplugged cable or the wrong phase rotation: small things like these easily lead to a technician driving out. A reporting system lets you clear them up beforehand. That is why needless service calls come first in our white paper "5 cost traps when renting out compactors" (German).
You will find more about the use case on the page Monitoring compactors remotely and technical details on the Packman page. We are also happy to show you the platform in a live demo based on your own workflows.
