Since uncoupling articulated trains is very time-consuming, they are usually lifted completely. The synchronization is done by PLC control and corresponding sensors. The software is developed in our own software department and adapted to the specific project. Thus, articulated trains with any number of wagons can be lifted. Systems for up to 8 wagons (32 synchronized lifting jacks) have already been delivered, larger systems with up to 12 wagons are currently being planned.
