A self-propelled object-gathering apparatus includes a chassis, a drive system coupled to the chassis and configured to traverse the apparatus over a surface, and a receptacle coupled to the chassis. The apparatus also includes a sweep assembly coupled to the chassis and rotatable with respect to the chassis. The sweep assembly is configured to transfer objects from the surface into the receptacle by mechanical action on the objects, and without the use of negative pressure or vacuum suction acting on the objects during the transfer, in response to rotation of the sweep assembly.

A loading area (1) for road sweeper (10) is provided comprising a tub (2) suitable to contain waste and defining at least an opening (20) through which waste can escape from the tub (2), a complementary surface (21) adjacent to the opening (20), a lid (3) configured to occupy, on command, the opening (20); a constraining mechanism (4) constraining in a compliant way the lid (3) to the tub (2) in such a manner to determine at least a closing configuration in which the lid (3) occupies entirely the opening (20), and an opening configuration in which the lid (3) frees entirely the opening (20); operation means (5) operatively connected to the constraining mechanism (4) and configured to bring the constraining mechanism (4) from the closing configuration to the opening configuration or vice versa; in which the constraining mechanism (4) is connected to said tub (2) at the complementary surface (21) and it is configured so that, in the opening configuration, the lid (3) is at least partially superimposed on the complementary surface (21).

A road or parking lot sweeper head comprises a sweeper base chassis comprised of a wheel carriage having at least two wheels attached. The wheel carriage attaches to an outer side of the sweeper base chassis and comprises a first wheel on a first side of the sweeper base chassis and a second wheel on a second side of the sweeper base chassis. Wherein the first wheel and the second wheel position the sweeper head above a surface at a proper operating height for an associated vacuum and to engage the surface in operation and prevent any portion of the sweeper head from contacting and damaging said surface.

A vehicular sweeping machine includes a frame and a broom assembly that is mounted to the frame. The broom assembly includes a broom enclosure, a left hub that is mounted on a left hub mount arm, and a right hub that is mounted on a right hub mount arm. A broom is mounted between the left hub and the right hub. An outer tube is attached to the rear of the broom enclosure and to one of the left and right hub mount arms. An inner tube has a fixed end that is attached to the left or right hub mount arm to which the outer tube is not attached. The inner tube also has a free end that is adapted to slide within the outer tube. A linear actuator is attached between the broom enclosure and the left or right hub mount arm to which the fixed end of the inner tube is attached. The linear actuator is adapted to move the hub mount arm to which it is attached between an inner position in which the broom is engaged with the left hub and the right hub and an outer position in which the broom is disengaged from one or both of the left hub and the right hub.

An industrial street sweeper attachment removably attaches to a prime mover with a quick coupler and has a forward debris collecting hopper mounted on the front of a rotary brush compartment having a floating sweeping brush therein. The debris collecting hopper is hingedly attached to the brush compartment and has a linkage therebetween having a lifting arm and a lifting hydraulic cylinder which can remotely lock the debris collecting hopper to the brush compartment to receive swept debris from the rotary sweeping brush and can be remotely lifted to an open position for discharging debris.

A road sweeper machine (1) is provided comprising a vehicle (2) suitable for road transport e comprising an electric motor (3), sweeping elements (4) connected to the vehicle (2) and suitable to remove waste on the ground, a waste collection system (5) placed at the bottom of the vehicle (2), a chamber (6) for containing the collected waste connected to the collection system (5), the electric motor (3) is of brushless type and comprises a hexa-phase system (30), the hexa-phase system (30) comprising a rotor (31) comprising a plurality of magnets of permanent type, two stators (32), two inverter circuits (33), each one connected to one of the stators (32), and each one mutually independent, each inverter (33) being capable of sending a three-phase current to the connected stator (32).

A vehicle includes a frame and a debris hopper including a door disposed along a side of the vehicle. The vehicle also includes front and rear lift assemblies supporting the debris hopper on the frame and configured to lift and tilt the debris hopper relative to the frame. Each lift assembly includes a transverse support mounted across the frame. A lift arm including a first end and an opposite second end, with the first end of the lift arm pivotably coupled to one end of the transverse support. A leg extending below the debris hopper and disposed proximate the door, with the second end of the lift arm pivotably coupled to one end of the leg opposite of the debris hopper. A first fluid actuator extending between the transverse support and the lift arm, and a second fluid actuator extending between the lift arm and the leg.
