The importance of washing down your road sweeper after use
Road sweepers when on site are often working in the worst conditions so if you include an end of day wash down procedure then it will be most beneficial and in turn save you money on maintenance and valuable downtime.
At the end of the shift empty the sweeper of waste and wash down the sweeper including inside the waste hopper. The waste should be tipped as when it is fresh it is loose so will easily discharge from the sweeper body, leave it over night or even worse over the weekend and it may well set meaning that someone has to dig out the waste before its next use wasting maybe an hour or so of valuable sweeping time.
Remember the sweeper is working in dirty conditions so it is very easy for dirt to gather around electronic parts such as alternators and valves which operate the hydraulics. Over time of not being cleaned this can cause wires to break or rot and also allow dirt ingress around rams and even the fuel tanks stopping things from working freely or contaminating fuel systems causing you costly downtime. Use the jet wash to blast away as much dirt as possible but at the same time do avoid heavy washing of sensitive parts for example around the ECU's on the sweeper. This will get the parts dirt free and allow them to dry off. Cleaning the inside of the waste hopper is equally as important as this is where the mesh screens are which are basically the filters for the sweeper. These screens can be found on the roof of the hoppers in all sweepers and over time gain a build up of mud and also leaves, litter and nasty things such as human hair or litter which reduces the airflow out of the sweeper body and also for the sweeper to be able to continue to suck air into the machine it must also be able to let air escape. Usually if an operator is moaning about poor suction on a sweeper it is a good chance that they have overseen the cleaning of inside the waste hopper. Also make sure the suction tubes/trunking are clean. These can also gather a dirt build up or have debris causing blockages. We have seen small branches, plastics and waste timber cause many engineer visits to site resulting in unwanted bills.
