How to Transport an Excavator
The width, weight and permit thresholds that decide which machine you can actually haul — and why transport cost can erase an auction bargain.
Transport is a hard constraint on which machine a buyer can actually own, and a real cost on every auction purchase.
The legal thresholds that matter (typical US rules; states vary)
- Width: 8 ft 6 in (2.59 m). At or under this, no oversize permit on most roads. Every mini and midi excavator fits; nearly all 20-ton-class machines are 2.8–3.0 m wide and therefore run as permitted oversize loads.
- Gross combined weight 26,001 lb: above this generally requires a CDL. A pickup + trailer + 4 t mini can stay under it; a midi usually pushes past.
- 80,000 lb gross on interstates without overweight permits — tractor + lowboy + 36 t excavator exceeds it, so large machines move on permitted multi-axle setups.
Practical pairings
- Mini ≤ 4 t: heavy pickup (¾–1 ton) + 10–14k equipment trailer.
- Mini/midi 4–9 t: medium-duty truck or small tractor + 14–25k tag trailer.
- Standard 13–24 t: tractor + lowboy/RGN; over-width permit in most states; $500–2,000 per regional move, more cross-country.
- Large 25 t+: permitted oversize/overweight, sometimes escort vehicles; plan thousands per move.
Buying-decision implications
- A remote auction machine that needs a 1,000-mile permitted haul can erase an apparent bargain — always price the haul before bidding.
- Boom/stick and counterweight removal can bring a large machine under weight limits but adds rigging cost at both ends.
- Transport height: 20-ton machines fold to ~3.0–3.2 m; verify total loaded height against 13 ft 6 in (4.11 m) bridge clearance on the route.
General guidance to help you shop — figures are typical ranges, not a valuation. Confirm the specifics of any machine with the seller before you buy.
