Start with the yard, not the machine
Most feed-loading sites have hard limits that decide which equipment can be used at all. Walk the wash route and record the entrance height and width, the slope of the apron, the gap between tanker and wall, and whether the operator has room to drive a unit through. The PWD02 series is a driven machine, so an aisle it cannot turn in removes it from consideration immediately. Note also where the water supply and the nearest power point sit relative to the wash bay — measured along the route, not in a straight line.
Then deal with the water. Wash water from a feed truck carries residues, and how you may discharge it depends on the site and the local rules that apply to it. Decide this before the trial, because if the water has to be recovered, the method changes more than the equipment choice does.
Define one trial, on one truck, with a fixed observer
A useful trial is narrow. Pick the worst-case vehicle in the fleet — the one with cured residue in the hopper corners, not the easiest one. Wash it with the current method first and photograph the result, then repeat with the new one. Keep the operator, the shift length, and the ambient conditions as close as you can between the two runs, and have one person record what happens rather than relying on the operator's recollection afterwards.
Record four numbers for both methods: start-to-finish time, water used, whether any chemical was needed, and how long the vehicle had to dry before it could be loaded again. Those four are what finance will ask about, and they are also what tells you whether the trial is comparable.
Check the safety points a feed yard actually creates
- Wet floor under the tanker. Steam produces less runoff than a hose, but it still leaves a wet apron — confirm drainage and check operator footwear.
- Hot surfaces and steam discharge near the tanker shell and near people. Set a clear exclusion distance for anyone not operating the unit.
- Electrical supply in a damp, dusty area. Confirm the outlet rating, cable condition and routing before the first run, and keep the cable off the wash path.
- Residue run-off entering the yard drainage. Photograph the drain before and after so you know what the process is actually discharging.
For the battery-equipped variant, the product page lists leakage, short-circuit, high-temperature, high-voltage and water-shortage protection functions. Treat those as items to verify against your own site safety paperwork, not as a substitute for a risk assessment. Where an area is classified or has dust controls, those rules govern before any equipment choice is made.
Confirm the feed-safety question separately
Cleaning a hopper that has carried feed is a feed-hygiene matter, not a machine specification. Your own rules on residue removal, any carryover restrictions between loads, and any requirement about detergents apply regardless of what is advertised. Write the answer down for the trial and have the person responsible for feed hygiene sign it. We will not state a hygiene outcome for your site from a product listing.
Then test the shift, not the machine
The second trial week is the one that matters. Run the equipment across a normal week, with the normal number of trucks, and watch the things that never appear in a single-vehicle test: how long refilling and setup take between units, whether operators keep to the written procedure, how the crew handles the machine between washes, and what happens when a shift runs late. A PowerDe cleaning equipment unit that needs a dedicated operator on a busy morning may simply move the bottleneck rather than remove it.
What to decide before you order more than one unit
Three things should be settled on paper after the trial: the configuration that fits your site (including whether a battery-equipped or mains-supplied unit suits your yard), the utility requirements at each wash point, and the written operating procedure your staff will follow. Published specifications on manufacturer sites are not always identical between pages, so any figure you rely on for approval should be confirmed in writing on the quotation.
If your trial plan currently has no named observer, no fixed vehicle, and no record of the current method, that is the reason the last equipment decision stalled. Fix those three things first — contact our team with your yard dimensions and the numbers from your existing process, and the configuration question closes in one round instead of several.
