When pallets need to be loaded and unloaded from an upper floor and a forklift or a stacker will be used for this job, a sort of platform dock needs to be installed on the façade.
With the installation of this automatic barrier the pallet can be left on the platform and be safely removed from it later on.
The barrier is activated with a pneumatic cylinder, which receives a signal from the operator by means of a remote control. In this way the workers on the top floor do not have to deal with the barrier, which will always be down and will be raised only at the moment of exchanging the pallet.
The operation is carried out so that while the barrier is raised a light or acoustic signal is activated and the door remains closed without the possibility of opening.
The system includes the pneumatic installation and the electrical control panel.
