Today's Work Problem

[den]

Task: Design a fully automated portable, dismantleable steel galvanized truck underbody wash that uses no pumps or electrical systems at all. This is going into a mine so they will be supplying the high-pressure water, and explains why they don't want a spark-risk due to electical system (even micro-voltage systems are not acceptable). Wash must support heavy mining equipment as well as light transports.

The Problem: "$65,000?! That's far too expensive! We budgeted on $5,000. Okay, can you supply one for less than $10,000?"

The dirty water has to be used because that's all there is. It's the same water they use to wet the coal face during drilling.

The fully automated system is: truck hits trigger1, wash starts, truck drives through and gets blasted with high pressure water from 80 nozzles, truck hits trigger2, wash stops. Due to coal dust, methane and being 6km underground, there can be NO electrical system. It all has to be mechanical to reduce the fire risk.
