Our semi-automatic postal traying system

Filling post boxes with envelopes and lifting the filled boxes is a constant strain on the operator's back. The reduction of the processing speed to prevent this stress is not an option. With our semi-automatic postal traying system W+D PT4 for C6 to C4 formats we offer you the solution to this challenge. The system supports all common post boxes and enables you to increase the speed of your envelope inserter to the maximum while minimizing the physical strain on the operator.
