Sweeper KM 2301
The sweeper KM 2301 was built by VEB Spezialfahrzeugwerk Berlin and presented at the Leipzig autumn fair in 1981 . It replaced the KM 21 D sweeper, which had been in production since 1970 and which had been exported particularly successfully up until then. The KM 2301 was designed for year-round cleaning of cuttings and surfaces in public traffic areas, as well as factory streets and storage areas. Sweeping was possible when the outside temperature was between 0 and 35 ° C.
Structure and technology
Series chassis were used for the first time on the KM 2301. The ventilated and heated work cabin enabled a good view and offered a certain level of comfort thanks to clear operation and control. The entry height to the cabin was 500 mm. Entry and exit were via sliding doors. The sweeper was driven by a hydrostatic-mechanical drive system. This eliminated the work engine that was otherwise used up until then. In addition, minimum sweeping speeds were possible for extreme soiling. The 7 m³ waste container could be filled with an intake rate of 90 kg / min. The discharge time was about 5 minutes. Tipping hydraulics with a long-stroke, double-acting working cylinder was used to empty the waste container. The water tank had a volume of 1.1 m³ and was installed between the front and rear axles. Instead of a bumper, an equipment rack was attached to the front of the vehicle . Connected to this were connections for hydraulics, electrics, water and pneumatics.
In the sweeping operation, water was sprinkled forward, which should also reduce fine dust pollution. The rotating side brush led the rubbish from the cutting channels in front of the rotating roller brush. There the rubbish was pneumatically sucked off via the suction nozzle and fed into the rubbish bin via a corrugated hose. Objects that could not be picked up automatically were disposed of via the bulky goods flap. Water that collected in the waste container could be drained separately. A sieve collected light debris such as leaves or paper and separated them.
The service life was estimated at 7 to 9 years, depending on whether the sweeper was running in one or two shifts.
