How to Ship a Bulldozer: Dimensions, Trailers, Permits & Costs
Shipping a bulldozer requires specialized heavy-haul equipment, oversize permits, and careful load planning — especially for larger machines like the Cat D8 or Komatsu D155 that can weigh 70,000 lbs or more. This guide covers everything you need to know about bulldozer transport: dimensions, trailer selection, permit requirements, loading procedures, and cost factors. IronHaul Logistics moves dozers of all sizes nationwide, from compact D3-class machines to large mining-class dozers.
Bulldozer Weight and Dimension Ranges
Bulldozers vary enormously in size, from compact utility dozers to large mining machines. Understanding your machine's specifications is the first step in planning a transport:
| Machine Class | Example Models | Operating Weight | Width (w/ blade) | Height |
|---|---|---|---|---|
| Small/Compact | Cat D3, Komatsu D37 | 15,000–22,000 lbs | 8–9 ft | 8–9 ft |
| Mid-Size | Cat D6, Komatsu D65 | 35,000–45,000 lbs | 10–12 ft | 10–11 ft |
| Large | Cat D8, Komatsu D155 | 65,000–80,000 lbs | 12–14 ft | 11–12 ft |
| Mining Class | Cat D11, Komatsu D475 | 100,000–230,000 lbs | 14–20 ft | 12–15 ft |
Note: Blade attachments (straight blade, angle blade, U-blade) significantly affect width. Always measure your specific machine with blade in transport position before booking transport.
Trailer Selection for Bulldozer Transport
The right trailer depends on your dozer's weight and dimensions:
- Lowboy (Double-Drop): The most common trailer for mid-size to large dozers. The low deck height (approximately 18 inches) keeps overall load height manageable for machines that are 10–12 ft tall. Standard lowboys handle up to 40–50 tons; heavy-duty lowboys handle up to 80 tons.
- RGN (Removable Gooseneck): Best for large and mining-class dozers that need to be driven onto the trailer. The detachable gooseneck allows the machine to drive directly onto the deck, eliminating the need for ramps or cranes. RGNs are available in configurations handling 50–150+ tons.
- Step Deck: Suitable for smaller dozers (D3–D5 class) that fit within step-deck height limits. Not recommended for machines over 10 ft tall or 40,000 lbs.
- Flatbed: Only appropriate for very small dozers (under 8.5 ft wide and 8.5 ft tall) that fall within legal dimensions — rare for most bulldozers.
Permit Requirements for Bulldozer Transport
Most bulldozers require oversize/overweight permits because they exceed standard legal limits:
- Width: Federal legal limit is 8.5 ft. Most dozers with blades are 10–14 ft wide, requiring oversize permits in every state along the route.
- Height: Federal legal limit is 13.5 ft (some states allow 14 ft). Most dozers on lowboys are 12–14 ft tall, often requiring permits.
- Weight: Federal GVW limit is 80,000 lbs. Large dozers (D8 and above) often exceed this, requiring overweight permits.
- Escort vehicles: Loads over 12 ft wide typically require a front escort vehicle. Loads over 14–16 ft wide require both front and rear escorts, depending on the state.
Loading and Securing a Bulldozer
Proper loading prevents damage and ensures DOT compliance:
- Drive-on loading: RGN trailers allow the dozer to be driven directly onto the deck — the safest and most common method for large machines. The machine should be driven in reverse so the heavier engine end is toward the front of the trailer.
- Ramp loading: Lowboys use ramps for loading. Ensure the ramps are rated for the machine's weight and the ground is level and stable.
- Blade position: Lower the blade to the deck and secure it. If the blade cannot be fully lowered, it must be secured independently.
- Ripper/attachment: Lower and secure all rear attachments (rippers, winches). Remove attachments if they create excessive overhang.
- Tie-downs: Under 49 CFR 393.130, equipment over 10,000 lbs requires a minimum of four independent tiedowns with an aggregate Working Load Limit (WLL) of at least 50% of the machine's weight. Use Grade 70 or higher chains and binders.
- Track chocks: Place chocks or track stoppers to prevent the machine from rolling during transit.
Cost Factors for Bulldozer Transport
Bulldozer shipping costs vary based on several factors:
- Distance: Per-mile rates typically range from $3–$8 per mile depending on load size, route, and market conditions
- Machine size: Larger machines require heavier-duty trailers and more permits, increasing costs
- Permit fees: State permit fees range from $15–$200+ per state, with superload permits costing significantly more
- Escort vehicles: Pilot cars typically cost $2–$5 per mile per vehicle
- Fuel surcharges: Applied based on current diesel prices and route distance

Common questions
What trailer do I need to ship a Cat D8 bulldozer?
A Cat D8 weighs approximately 73,850 lbs and is typically 12–14 ft wide with the blade. It requires a heavy-duty lowboy or RGN trailer rated for 40+ tons, plus oversize/overweight permits in every state along the route.
How many tie-downs are required to secure a bulldozer for transport?
Under FMCSA 49 CFR 393.130, equipment over 10,000 lbs requires a minimum of four independent tiedowns with an aggregate Working Load Limit of at least 50% of the machine's weight. Grade 70 or higher chains and binders are required.
Do I need escort vehicles to ship a bulldozer?
Most mid-size to large dozers (D6 and above) are wider than 12 ft with the blade, requiring at least a front escort vehicle. Loads over 14–16 ft wide require both front and rear escorts, depending on the state.
Can the blade be left on the bulldozer during transport?
Yes, in most cases. The blade must be lowered to the trailer deck and secured. If the blade creates excessive width (over 16 ft), it may need to be removed or transported separately to reduce permit complexity.
How much does it cost to ship a bulldozer across the country?
Cross-country bulldozer transport typically costs $5,000–$15,000+ depending on machine size, distance, permit requirements, and escort needs. IronHaul provides free quotes with all-in pricing including permits and escorts.
