Bucher C202

The Bucher C202 is Bucher Municipal's compact sweeper, available with optional four-wheel steering, and Bucher itself calls it a class leader. Its design is guided by six goals defined by the customers themselves:

• high performance
• high productivity
• low cost of ownership
• minimal environmental impact
• safety
• a good driver environment

The machine is under 2 metres high – 1985 mm – even with a roof-mounted wander hose, so it can get into multi-storey car parks and under bus shelters where other sweepers cannot. Bucher emphasises that the C202 can stay out on the job for longer. According to Bucher, it has enough water, enough hopper capacity, enough payload and enough fuel to last the whole shift, while other machines have to return to base to empty, fill up with water or refuel.

Engine and driveline

The engine is a 2970 cm³ four-cylinder low-emission diesel. In the Euro 6c version (R754EU6C) it delivers 62 kW and 270 Nm, and the machine is also supplied as Stage 5 (R754ISE5, 55 kW / 310 Nm) and Stage 3A (D754TE3, 54 kW / 255 Nm). The driveline is infinitely variable and hydrostatic, and switches seamlessly between forward, reverse and working mode. Thanks to a well-thought-out design, the C202 delivers high performance at lower engine speeds, which Bucher says gives up to 40% lower fuel consumption. The working speed is 0–16 km/h, the transport speed 0–50 km/h and the gradeability 30%. With optional four-wheel steering, the turning radius is 2110 mm from kerb to kerb.

Brush system and dust suppression

The brush system is forward-facing with independent brush arms that maximise the sweeping width, and the max. cleaning width is 3120 mm. Each brush arm has water jets that lay a fine fresh water spray over the dust the brushes stir up. In addition, recycled water from the hopper load is filtered through stainless steel wedge-wire panels and pumped into the inlet duct of the suction mouth, so that all the material is wetted on its way through the water curtain and falls safely into the hopper. The driver can see the front edge of the suction mouth and can open the leaf flap or lift the mouth to avoid material being pushed in front of the machine.

Hopper and water

The 1.8 m³ hopper is made of stainless steel 1.4003 and discharges at a height of 1545 mm, which suits containers and waste bins. The fresh water tank holds 152 l on Euro 6c and Stage 5 (175 l on Stage 3A), and the recirculation tank 250 l.

Cab and operating costs

The cab is a spacious walk-through cab with a fully suspended driver's seat, three-point seat belt, ergonomically placed centre armrest and adjustable steering column. The overhead console houses light switches, radio and a 7-inch colour screen that alerts the driver to faults and logs operating data that can be retrieved via USB. The windscreen is electrically heated with rapid defrost, and the floor windows give a direct view of the suction mouth. The noise level is 67–75 dB(A) in the cab depending on working speed, and 97 dB(A) externally while sweeping. Operating costs are kept down with tubeless industrial tyres that last three times longer than commercial tyres, steel pipes instead of flexible hydraulic hoses, LED work lights as standard and a service interval of 500 hours.
