It is the advantage of the Heesemann compact construction that the sanding machines are delivered completely wired in one piece to the final customer. Therefore, saving of time can be realized when stowing the truck or container. Also risks of wrong wiring at the place of the customer when the machine is supplied can be eliminated. The modular construction in one piece also allows an extremely short integration of the machine in already existing production lines. The result of this is a very short interruption of production. By means of a clear, closed outer "skin" at the machines - having no drives and motors or gears or even sanding units outside of the machine, the risk of collision with transport vehicles inside the production halls can be minimized at high scale. The modular construction concept also supports the cleaning process around the machine.
