Abstract: An apparatus for removal of material by suction, comprising, supported by the chassis of a truck, a partial vacuum unit for a collection tank, to which aspirated material is conveyed. The tank is fitted on an unloading device suitable to lift on one side the tank in order to empty by gravity the material accumulated therein. The unloading device comprises a frame rotatably coupled to the chassis by interposing a rotatable center bearing, provided with an actuation for actuating the rotation of the frame with-respect to the chassis. The frame has a base for connection to the center bearing, and a supporting structure for the tank is associated with the base. The structure is adapted for multiple movements for positioning and unloading the tank outside of the truck footprint.

Abstract: An apparatus for unwinding/rewinding a suction hose for draining or purging cesspools, septic tanks, sewers or the like which includes, on a truck, a reel with which, in a peripheral region, a radial hose guide is associated, the hose guide including a composite am with guiding elements for the hose, wherein the arm is peripherally articulated to the reel so as to pitch, in an adjustable manner actuated by actuation elements, about an axis which is parallel to a tangent to the reel.

Abstract: A suction system for urban wastes and for recyclable materials comprising a motorized transport means (10) suitable to receive urban wastes and/or recyclable materials placed in a container (36) or left on the ground, wherein said transport means (10) is provided with a sucking tube (15, 17, 18, 23) which can be moved in order to suck and/or which can be inserted by means of actuators (20, 25) inside an opening (30) formed in an underground container (36), closing means (27) are provided for the opening (30), said means being provided with an opening (35) of predetermined size. Preferably, said closing means comprise a sliding turret (27) which can be moved when the sucking tube is activated.
