The B172 live bottom is the first equipment in the world of its type to be equipped with two separate hoppers and two independent extraction belts. It can be installed on a truck or be equipped with a demountable or hooklift system. Optionally it can be equipped with an external tilting belt, inclinable up to 28 °, to transport the inert material at height, for example inside another hopper.
The operator can then decide to unload the material directly on the ground or at height using the external belt. Thanks to the double hopper, two different types of aggregates can be transported and unloaded separately, such as sand and gravel.
