Ready Mix Concrete Truck Wash

Sioux Truck Wash for Ready Mix Trucks

Sioux has developed the Ready Mix Truck Wash based on our 80+years of experience building cleaning equipment for demanding industrial applications. 


A ready mix concrete truck slowly approaches the wash tower with its drum in rotation when sensors on the wash tower start the cleaning process.  The cleaning cycle is made up of three different stages.  In one stage, a spray bar will apply a detergent or cleaning chemical to the sides of the truck.  Another stage has a series of rotary high pressure spray nozzles to clean the hopper to remove loose materials.  The driver slowly proceeds through the final set of spray bars that have high pressure nozzles to clean and rinse the top and sides of the truck in the third stage.  before proceeding to the job site.  A light bar assists the driver to determine proper positioning for each stage and counts down time remaining in each. 

The Cycle Swap feature of the Sioux unit allows drivers to quickly and easily change the system operation for front or rear discharge trucks by the touch of a button.  The entire cleaning process is completed in 1 minute or less to get drivers to the job site in a short amount of time.


The Sioux Truck Wash is essential for any ready mix producer for the following reasons.

  • Reduce the risk of injury - drivers do not have to get out of the truck and climb up to wash the hopper manually

  • Consistent loads - the same amount of water is added to each load (not dependent on the driver)

  • Fast and efficient - ready-mix truck is clean and ready to go down the road in 60 seconds

  • Flexibility - works on both front and rear discharge mixers

  • Professional company image - improve the look of the trucks and appearance to customers
  • Reduced water consumption and run-off - uses less water than manually cleaning

Cold Weather Package - This option will extend the length of time operators may use the system in cold climates. The Cold Weather Package includes a temperature sensor to automatically activate winterization mode if the ambient temperature is near freezing.  When enabled, only the hopper wash mode is activated to minimize ice build-up on the exterior of the truck and the wash pad area.  An extended air blow down between cycles and hose insulation with heat tracing prevents water from freezing in the lines.
