Binotto underbody telescopic cylinders are suitable for any type of rigid tipper chassis such as small tipping vehicles (3,5 ton GVW), commercial vehicles, crane-tippers, quarry and construction tippers. They are also the perfect choice for big tipper trailers and semitrailers with bulk payloads (operating in the agricultural, construction and mining sectors).
Thanks to special bespoke bracketry, cradle and body accessories, Binotto underbody telescopic cylinders turn out to be a very versatile solution suitable for rear tipping and for side tipping vehicles: they can be installed in 1-way, 2-way or 3-way tipping vehicles, as an option.
They can be mounted as a single piece or in pairs. In case of longer bodies (such as for trailers and semitrailers) even more cylinders can be installed in the same vehicle.
Designed to be compact, light in weight and simple to operate, they are also easy to fit and maintain.



Binotto offers 4 standard series of underbody cylinders.
Custom solutions are also available upon request. Our R&D Department can also provide all the necessary engineering support to study and develop new projects according to specific body designs. Extensive technical expertise ensures a safe and reliable cylinder selection.
