Sand cleaning machine

from Wikipedia, the free encyclopedia

A sand cleaning machine (also sand processing machine or sand bonuses ) or beach cleaning machine (short beach cleaner ) is a cleaning and surface treatment of sandy beaches , sand playgrounds or beach volleyball courts employed mobile device. The term "beach cleaner" was formed analogously to the ice processing machines on artificial ice rinks , which in English-speaking countries received the generic name after the inventor and manufacturer Frank J. Zamboni .

functionality

A sand cleaning machine is either a self-propelled vehicle on four wheels or on chains, powered by an engine, or a trailer for a tractor. Gas-powered or diesel engines are mostly used for the drive . Larger machines are attached to Unimogs or tractors as trailers. These commercial vehicles mostly come from the agricultural or municipal technology sector and enable the use of more complex processing systems . The smallest devices are guided and pushed by the operator, similar to a lawn mower .

The sand is transported upwards via a pick-up and separated into differently sized and heavy components via a vibrator or sifter. The machine separates waste into a separate container and returns the sand to the beach or playing field. Depending on the process, not only are coarser particles sorted out, but finer fractions such as silt or silt are also separated out. The sand comes into contact with air, is loosened and has a lower cohesion and higher flowability. In sports applications such as playgrounds, this improves hygiene and fall protection.

application

At the 1996 Summer Olympics in Atlanta , the term "beach cleaner" was applied to stationary systems that were used to smooth long jump pits after jumping. According to sports official Phillip L. Henson, the athletes were very satisfied. With regard to the possible loss of jobs for human sweepers, who then have to retrain on computers, Henson only said that this was the traditional man-machine competition.

A special feature of the 2008 Summer Olympics in Beijing were remote-controlled, futuristic-looking beach cleaners that were used for the beach volleyball fields of the tournament in Chaoyang Park .

One non-sporting use was beach cleaners, which were used to clean beaches after the 2010 Gulf of Mexico oil spill . The machines used in the Gulf of Mexico come from the Cherrington company from North Dakota , where there are no beaches. They are usually on the road cleaning tourist beaches of human remains such as cigarette butts and broken glass and removing sharp-edged mussel shells. Smaller machines clean sand in children's playgrounds and in sandboxes.

The 22 miles of beaches on the Gold Coast in Queensland , Australia are visited by millions of tourists and every night the area between the waterline and the dunes is cleaned by four tractor-pulled beach cleaning machines. This type picks up and cleans the top 6 ”layer of sand. Other parts of the beach region are only visited weekly. A total of 31 tons of gravel , rubbish, seaweed , jellyfish and small flotsam are removed every week .

In 2009, Miami-Dade County in Florida carried out a competition for beach cleaning as part of a tender, in which the four leading manufacturers in North America participated with their devices: Barber with Surf Rake , Cherrington with Beach Cleaner , Rockland with Beach King and Kässbohrer with BeachTech . In addition to the purchase and operating costs and the cleaning result, the wrongly picked up sand was also important in the competition, as it clogs the waste containers ahead of time and damages the beach by removing sand.
