In recycling plants, balers, shredders and conveyor belts play a crucial role in the processing and transport of materials. Employees who work on conveyor belts every day, sorting materials so that it can subsequently be compressed into bales, are exposed to a high safety risk.

To ensure employee safety, U-TECH has been supplying the GSG202A personal protection system (U-TECH PRESS) since 2003, which is specifically designed for use on conveyor belts and balers. Channel balers can be life-threatening, particularly when employees are working alone. If employees fall into the baler shaft and are unable to stop the baling process themselves, mechanical safety systems such as emergency stop cords often fail. So how can businesses prevent such accidents and ensure a safe workplace?

The solution: the GSG202A (U-TECH PRESS) personal protection system, which is based on RFID technology. Employees wear a special U-TECH PSM transponder on their wrist or in their work clothing. If the employee enters the danger zone, the antenna module reacts and sends a signal to the central control unit, which then automatically shuts down the machine.

The personal protection system consists of just three modules to be installed:

1. The control unit ALM monitors all incoming signals and triggers the machine to shut down automatically if the danger zone is entered or in the event of a fault, such as a failure of the UHF receiver.
2. The antenna module ANM is mounted on a bracket above the conveyor belt, at least 2 m in front of the baler shaft, and defines the required danger zone by means of an electromagnetic field.
3. The self-test module ETM is mounted on side wall of the conveyor and constantly monitors the stability of the electromagnetic field and the flawless operation of the system.

Thanks to the GSG202A (U-TECH PRESS) personal protection system, companies in the recycling industry can ensure that their employees are optimally protected whilst working on balers and conveyor belts.
