Heavy equipment
Heavy equipment hauling: trailers, securement, permits and what a move costs
By Mike Shelton · Updated · How we check facts
Which trailer fits which machine
The machine picks the trailer. Weight decides how many axles you need; height decides how low the deck must be. A machine that is legal on a lowboy can be over height on a flatbed, because a flatbed deck sits well above a lowboy's.
| Machine | Usual trailer | Why |
|---|---|---|
| Skid steer, mini excavator, small backhoe | Hotshot gooseneck, tag trailer or step deck | Light enough for legal weight; ramps for loading |
| Backhoe loader, mid-size excavator, small dozer | Step deck or lowboy | Height decides: the lower the deck, the taller the machine you can carry legally |
| Large excavator, dozer, wheel loader | Lowboy or RGN (removable gooseneck) | Low deck height; machine drives on over the front |
| Cranes, mining trucks, very large excavators | Multi-axle RGN, often with a jeep or booster | Extra axles spread weight to keep axle loads within permit limits |
| Tractors, combines, farm equipment | Step deck, RGN or lowboy | Wide headers and tall cabs often need width or height permits |
A lowboy has a deck that drops between the gooseneck and the rear axles. An RGN, or removable gooseneck, detaches its neck so the front of the trailer lowers to the ground and the machine drives on. More on the options in hauling trailers.
Securing equipment: the federal rules
- Wheeled or tracked equipment of 10,000 lb or more must be restrained against sideways, forward, rearward and vertical movement, with at least four tiedowns. 49 CFR 393.130Checked October 2026
- The working load limits of all the tiedowns together must add up to at least half the weight of the machine. 49 CFR 393.106(d)Checked October 2026
In practice, a 40,000 lb dozer needs chains and binders with a combined working load limit of at least 20,000 lb, attached at the machine's tie-down points, not around hydraulic lines. Lower the blade and bucket to the deck, lock articulation and swing, and check everything again after the first miles. Our load securement calculator does the arithmetic.
When a machine needs permits
The legal box on the Interstate is 102 inches wide 23 CFR 658.15Checked October 2026 and 80,000 lb gross, with axle groups held to the bridge formula. 23 CFR 658.17(b)Checked October 2026 23 CFR 658.17(e); FHWA Bridge Formula WeightsChecked October 2026 Height has no federal limit; states set it GAO-15-236Checked October 2026, from 13 ft 6 in in Pennsylvania PennDOT (75 Pa.C.S. 4922)Checked October 2026 to 14 ft in Texas.

Permits set the route, travel hours and escort requirements. Wide loads often need one or two pilot cars and can't move at night in many states. Check dimensions against the limits with the oversize load checker, and read who handles permits and escorts.
Loading and unloading safely
Most equipment injuries happen at the ramps, not on the highway. Park on firm, level ground, set the trailer brakes and chock the wheels. With an RGN, check the neck is locked down before anyone drives on. Have one person run the machine and one spotter in clear view, and agree on hand signals first. Wet or icy ramps and tracked machines are a bad mix: clean the tracks and deck, and add traction where you can. Once the machine is in place, set its brakes and locks before the first chain goes on.
Hauling heavy equipment with a hotshot
Skid steers, compact excavators and small tractors are steady work for hotshot rigs. Watch the ratings: a pickup and gooseneck rated 26,001 lb or more combined, towing a trailer rated over 10,000 lb, needs a Class A CDL. 49 CFR 383.5Checked October 2026 Many hotshot setups stay under that line, which caps the machines they can legally carry. Weigh the machine with its attachments, not just the brochure weight. Price these runs with the hotshot rate calculator.
How an equipment move is priced EXAMPLE
A long equipment move is built up from parts. Here is one way a carrier might price an over-width excavator move:
| Line | How it is set | Example |
|---|---|---|
| Linehaul | Miles × rate for the trailer and weight, including deadhead | $3,600 |
| Permits | Each state's fee for the dimensions and weight | $240 |
| Escorts | Pilot car miles where the permit requires them | $900 |
| Load and unload time | Hours at each end beyond free time | $150 |
| Total | $4,890 |
These numbers are made up to show the structure, not market rates. Permit and escort costs are often billed as separate lines on the rate confirmation. Check what the linehaul pays on every mile with the rate per mile calculator.
Construction hauling beyond machines
Construction material hauling, such as gravel, sand, asphalt and fill, is a different job: it moves in dump trucks and end dumps, priced by the hour, ton or load. See bulk hauling. Equipment haulers often pair with those fleets, moving the machines to the site that the dump trucks then feed.
What the shipper should have ready
A smooth move starts with the paperwork. The shipper should give the make and model, operating weight with attachments, length, width and height in transport position, and the pickup and delivery contacts with hours. Ask whether a loader or crane is on site for anything that can't drive on, and whether attachments ride on the same trailer. A wrong dimension can mean a permit that doesn't match the load, and a permit that doesn't match the load is a ticket or a parked truck at the first scale. Measure the machine as it will ride, with the boom, bucket and blade where they will sit on the trailer, and send photos if anything is unusual.
Choosing heavy equipment hauling companies
If you are shipping a machine, look for a carrier with active operating authority, cargo insurance that covers the machine's value, the right trailer and experience with your machine type. Ask who orders permits and escorts and how they are billed. For carriers, the bigger trade of oversize and superload work is covered in heavy haul trucking, and the wider specialty picture in hauling.
If you run a lowboy or RGN, the hard part is keeping it loaded between projects. Our oversize and heavy haul dispatch finds equipment moves, confirms the specs and permits, and calls you before anything is booked.
Questions and answers
01What is cat hauling?
Cat hauling is trade slang for moving heavy construction equipment, named after Caterpillar machines such as dozers, loaders and excavators. A cat skinner runs the machine; a cat hauler moves it between jobs, usually on a lowboy or RGN trailer. The term covers any brand of heavy machine, not just Caterpillar.
02How much does it cost to haul heavy equipment?
It depends on the machine's weight and dimensions, the distance, the trailer needed and whether the load needs permits, escorts or a route survey. Short local moves often price by the hour or a flat fee; long moves price as a linehaul plus permits and escorts. Get the machine's exact specs before you quote.
03What trailer do you need to haul an excavator?
Small excavators fit on a tag trailer or step deck. Mid-size and large excavators usually go on a lowboy or RGN, where the low deck keeps the load under height limits and the detachable neck lets the machine drive on from the front. Very large machines move partly disassembled on multi-axle trailers with permits.
04Do you need a permit to haul heavy equipment?
Only when the load is over the legal limits. A machine that keeps the truck within 102 inches wide, the state's height limit, legal length and 80,000 lb gross with legal axle weights moves without one. Most large construction machines exceed at least one limit, so they move on a permit from every state crossed.
