Pitless vs. pit truck scales: which is right for you?
Short answer: most operations today choose pitless (above-ground) scales for faster installation, easier service, and lower long-term cost. Here’s how the two compare so you can decide for your site.
What’s the difference?
A pit scale sits in an excavated pit so the deck is flush with the ground. A pitless (above-ground) scale is built up from grade with open sides and ramps, typically standing about 11–20 inches above the surrounding surface.
Installation & cost
Pitless scales install faster and cost less to put in: there’s no deep excavation and no waiting on a large concrete pour to cure. A low-profile pitless deck like the TP Series keeps the above-grade height down while preserving the install and service advantages.
Service & maintenance
This is where pitless really wins. Open sides mean technicians can get under the deck to inspect load cells, clear debris, and make repairs without working in a confined pit. That translates directly into less downtime over the life of the scale.
When a pit scale still makes sense
If you’re tight on space and need a flush, drive-through deck, for example where trucks approach from multiple angles, a pit scale’s flush profile can be worth the added install cost and service complexity.
| Factor | Pitless | Pit |
|---|---|---|
| Install speed/cost | Faster, lower | Slower, higher |
| Under-deck service | Easy (open sides) | Harder (confined pit) |
| Footprint | Needs ramp approaches | Flush, compact |
| Relocation | Easier | Difficult |
