Often, drivers are no longer allowed to leave their truck during loading and unloading. Also, in some situations it is very difficult to unload without incurring damage, for example when unloading in an asphalt machine or in a quay. As a result, more and more operations are becoming fully automated or controlled from the cabin instead of performing the operation manually on the trailer itself.



One of these actions is the folding of the bumper during unloading. Our automatic folding bumper is a 'specialised option' that is controlled by a pneumatic cylinder. The cylinder is incorporated in a sturdy aluminium casing, from where the bumper is pulled up by a thick steel cable. This construction guarantees the perfect combination between light and strong.


Often a button is built into the cabin to operate the pneumatic bumper, but in principle this is not necessary for our vehicles at all: When the bumper is set to "automatic", the foldable bumper rises from the moment the body is tilted. Extra easy, because then the driver doesn't even have to think about this extra action. It goes without saying that as a driver you can also choose to operate the bumper separately from tipping, so that every possible situation can be handled in a comfortable manner. (Please note that the supplied security pins are fitted when you go back on the road).


In this way, the pneumatically folding bumper undoubtedly contributes to a carefree tipping experience: Making bulk transport... a pleasure.
