How to Ship an Excavator: Everything You Need to Know

Excavator Weight Classes and What They Mean for Transport

Excavator transport requirements are primarily driven by operating weight. Here's how the industry segments them:

Class	Operating Weight	Examples	Typical Trailer
Mini / Compact	Under 22,000 lbs	Cat 308, Komatsu PC88	Flatbed or Step-Deck
Mid-Size	22,000–55,000 lbs	Cat 320, Deere 350G	Step-Deck or Lowboy
Large	55,000–180,000 lbs	Cat 390, Komatsu PC800	RGN (Removable Gooseneck)
Mining / Ultra	180,000+ lbs	Cat 6060, Liebherr R 9800	Multi-axle RGN; partial disassembly required

The federal gross vehicle weight (GVW) limit on the National Network is 80,000 lbs. Any excavator that pushes the combined truck-trailer-machine weight over this threshold requires an overweight permit from each state on the route.

Trailer Selection: RGN vs. Lowboy vs. Step-Deck

RGN (Removable Gooseneck) trailers are the gold standard for mid-size and large excavators. The front gooseneck detaches, lowering the deck to ground level so the machine can be driven directly onto the trailer — no ramps, no crane required. Deck heights on RGNs typically sit 18–24 inches off the ground, maximizing vertical clearance for tall machines. Standard RGNs offer 29–53 feet of deck space; stretch configurations handle longer loads.

Lowboy trailers with fixed necks are suitable when loading equipment is available on-site (crane or forklift). They typically carry 40,000–80,000 lbs and offer 24–29 feet of deck space. They're a cost-effective option when the excavator is non-operational and a crane is already on-site.

Step-deck trailers work well for compact and some mid-size excavators that fit within standard height limits. The lower rear deck (typically 36–42 inches off the ground) provides more clearance than a flatbed without the cost of a lowboy.

Oversize Permit Thresholds

Federal law sets the baseline: loads exceeding 102 inches (8.5 feet) in width are classified as oversize and require state permits. Most excavators in the mid-size and large categories exceed this threshold due to track width. Key thresholds to know:

• Width over 8.5 ft: Oversize permit required in every state on the route
• Width over 12 ft: Front escort vehicle typically required
• Width over 14 ft: Front and rear escorts required in most states; some states require law enforcement escort
• Height over 13.5 ft (combined trailer + machine): Permit required; route must be surveyed for bridge and overpass clearances
• GVW over 80,000 lbs: Overweight permit required; axle spacing and bridge formula calculations apply

Note: There is no federal height limit — state limits vary from 13.5 ft to 14.5 ft. Western states tend to be more permissive; Northeast states often have stricter clearance requirements due to older infrastructure.

Preparing Your Excavator for Transport

Proper preparation prevents damage and keeps the move compliant:

• Retract the boom and stick fully and lower the bucket flat against the deck to minimize height
• Lock the house rotation — the turret must be pinned or chained to prevent swing during transit
• Engage the parking brake and verify it holds
• Remove or secure all attachments — buckets, thumbs, and quick couplers should be pinned or removed
• Clean the undercarriage — many states require clean equipment to prevent invasive species spread; it also makes tie-down point inspection easier
• Document existing damage with dated photographs before loading
• Check fluid levels — leaking hydraulic fluid or fuel is a DOT violation during transport

Securement Requirements (FMCSA)

Per FMCSA cargo securement rules, the aggregate working load limit of all tie-downs must equal at least 50% of the equipment's weight. For excavators over 10,000 lbs, a minimum of four direct tie-down points are required — one at each corner of the machine. Chains must be Grade 70 or higher. Tension must be checked after the first 50 miles and at each rest stop thereafter.

Cost Factors for Excavator Shipping

Excavator shipping costs typically range from $1,500 for short regional moves to $8,000+ for cross-country hauls with superload permits. Key cost drivers:

• Distance and routing complexity
• Machine weight and width (determines permit tier and escort requirements)
• Operational vs. non-operational status (non-op requires crane loading)
• Number of states crossed (each state charges its own permit fee)
• Seasonal demand and fuel surcharges
