Safe hands

A SAFETY wheel chock is part of the loading bay system installed by the DELFI company. The ISOCube system from manufacturer Promstahl is proving to be an optimal docking solution for the site’s requirements.

DELFI was looking for a docking system that meets both the high safety requirements applicable in France and special thermal and hygienic requirements.

The French authority responsible for work safety and security visited the site and evaluated it to be a potential model facility for safe and secure docking.

The reason for this is the combination of safe and fast docking including the safety zone highly recommended in France with an intelligent vehicle detection system with height-adjustable buffers (PGV) guaranteeing efficient vehicle positioning.

The sequence of a docking process is as follows: After the truck has docked in, the safety wheel chock (PZK) is positioned, the industrial door (PDAI) is opened and the dock shelter (PWI2) is automatically inflated. Then the height-adjustable buffers are lowered. Subsequently, it is possible to open the rear doors of the truck by bridging the safety zone by pressing the Advance button of the dock leveller control box (PAT2). The driver and the warehouse staff are constantly being informed about the status of the loading / unloading process by means of the traffic lights system that includes a vehicle detection system.

After completion of the loading / unloading process, the dock leveller returns to its truck door closing position by pressing the additional Advance button. Subsequently, the leveller returns to its resting position by pressing the Auto button. Finally, the height-adjustable buffers are lifted to their topmost position. It is only now that the industrial door can be closed. This sequence guarantees a safe dock-in process for the next vehicle.

After the industrial door has been closed and the dock shelter automatically deflated, the traffic lights are blinking (red / green) indicating the driver that the loading / unloading process has been completed but that the wheel chock is still positioned under the truck wheel.

Finally, the wheel chock is taken away from under the wheel and positioned in the related support. Now the external traffic lights become green and show the driver that he can leave the docking station.

The housing can be delivered with or without cladding and can be built as 90° and 45° versions.
