Abstract:
1. An apparatus for removal of material by suction, comprising: a partial vacuum unit and a collection tank which are supported by a chassis of a means of transport; suction means associated to said collection tank to convey material aspirated by said vacuum unit from said tank; unloading means on which said tank is fitted and which are suitable to lift on a first side said tank to empty by gravity material accumulated therein through an openable unloading bottom of the tank arranged at a second side of said tank opposite said first side of said tank, and wherein said unloading means comprise: a center bearing, which rotates about a vertical axis; a frame which is rotatably coupled to said chassis by interposition of said center bearing, said center bearing being provided with actuation means for actuating rotation of the frame with respect to the chassis, said frame having a base for connection to the center bearing; a supporting structure for said tank being associated with said base, said structure having multiple movement means for positioning and unloading the tank outside of a footprint of the means of transport, said unloading means comprising actuators which are interposed between said structure and said first side of said tank, and said multiple movement means of said structure comprising telescopic arms and a cross-member of the structure which connects ends of said arms and to which said second side of said tank is pivotally, and fluid-operated actuation means by way of which said telescopic arms are extendable/retractable to move said second end of said tank away/toward a spaced occupation of the means of transport.
