They go out every night to empty trash cans in towns and cities around the world; every day our streets look cleaner thanks to them, but do you know how garbage trucks are washed? Let's start the year with a topic that is likely to make CarLover curious and observant. Let's talk about waste collection vehicles.
Contrary to what some of you may think, garbage trucks can be washed; in fact, they wash a lot because they get dirty every day. With a very distinctive shape, garbage trucks are part of the garbage collection vehicle fleets used by municipalities for urban cleaning. These vehicles may have a front loader unit or a rear loader. The system collects and empties the garbage containers in the truck; The garbage is then compacted with the help of a baler knife to reduce the volume of waste collected.
All these teams make the truck have a strange shape that varies from country to country. Therefore, the most suitable washing method for this type of vehicle is high pressure without brushes, since these could not reach all the holes, grooves, and recesses of the complex bodywork. With small fleets, a non-contact rollover can be used, including high pressure and chemical spraying on the sides, roof, and rocker panel. The rollover moves through the vehicle in multiple passes lasting about 12 minutes in total.
However, for fleets with more than 15 trucks to wash daily - which is the most common case - a drive-through system is used: it is the truck that moves slowly through a wash lane. This washing lane is equipped with different washing systems: the rocker arm area is washed, a foamy chemical is sprayed that completely covers the vehicle, high-pressure water is applied through a washing arc formed by rotating nozzles, and then perform a final rinse. All of this is done in just a minute and a half.
The high rotary pressure has proven to be the best system when it comes to very fast and frequent washing. A garbage truck detail is generally washed every 3 days; more commonly, they are washed after the night shift, once the vehicle is back in the parking lot. This way, garbage trucks are clean and ready to do their job the next day.
The use of this type of system ensures optimal maintenance with reduced water consumption compared to manual washing. Our equipment can use recycled water during high-pressure applications. Being respectful of the environment is a key requirement that also applies to garbage trucks. Soon, these vehicles will be electric, which makes sense given the focus on the sustainability of urban waste management.
