Everything you need to know about heavy haul trucking — from weight thresholds and permit requirements to trailer types, costs, and how to choose the right carrier.
What Is Heavy Haul Trucking?
Heavy haul trucking is the transport of loads that exceed standard federal legal weight and/or dimension limits. Any shipment that surpasses these federal thresholds requires specialized equipment, state-by-state permits, and in many cases, pilot/escort vehicles:
- Weight: Over 80,000 lbs gross vehicle weight (GVW)
- Width: Over 8.5 feet (102 inches)
- Height: Over 13.5 to 14 feet (varies by state)
- Length: Over 48–53 feet (varies by state and trailer configuration)
When a load exceeds any one of these limits — even if the others are within legal range — it becomes a “permitted load” and must travel under state oversize/overweight (OS/OW) permits.
At Freedom Heavy Haul, we move loads up to 250,000 lbs and wider than 20 feet, all 48 contiguous states. Here’s what you need to know before you book.
What Qualifies as a Heavy Haul Load?
Heavy haul encompasses a wide range of industries and equipment types. Common loads include:
Construction Equipment
- Excavators (10,000 – 200,000+ lbs)
- Bulldozers and dozers (30,000 – 130,000 lbs)
- Motor graders (30,000 – 65,000 lbs)
- Cranes and boom lifts (20,000 – 300,000+ lbs)
- Compactors and rollers (20,000 – 50,000 lbs)
Oil, Gas & Energy
- Transformers (50,000 – 500,000+ lbs)
- Generators and power units (20,000 – 150,000 lbs)
- Pressure vessels and tanks (varies widely)
- Wind turbine components (blades 15,000–30,000 lbs; nacelles up to 100,000 lbs)
- Drilling equipment and rigs
Mining Equipment
- Haul trucks and dump trucks (40,000 – 80,000 lbs)
- Draglines and continuous miners
- Large loaders and scrapers
Agriculture
- Large tractors and combines
- Irrigation systems and pivots
Industrial & Manufacturing
- Industrial machinery
- Steel beams, structural components
- Modular structures and prefab units
If your equipment has tracks, oversized tires, or can’t be dismantled for standard freight, it almost certainly qualifies as heavy haul.
Heavy Haul Permits: What You Actually Need
This is the part most carriers keep vague. We don’t. Here’s exactly how it works.
Single-Trip vs. Annual Permits
Single-trip permits are issued for one specific trip on a defined route. Required for most super loads (200,000+ lbs) and all unusual-dimension loads. Cost ranges from $15–$200 per state depending on dimensions and weight.
Annual permits (also called “blanket” permits) cover repeat movements within a state for loads within certain standard dimensions and weights. Common for contractors moving equipment frequently within a single state. Typically $50–$300/year per state.
What Determines Your Permit Requirements
Four factors determine which states require permits and what type:
1. Gross vehicle weight — heavier loads trigger more restrictive requirements
2. Axle weights — not just total GVW; each axle grouping has legal limits (federal bridge formula)
3. Width — loads over 12–14 feet wide often require nighttime travel restrictions and pilot cars
4. Height — loads over 14–15 feet require route surveys for bridge and overhead clearance
Typical Timeline
Standard loads (under 200,000 lbs, under 14 ft wide): 3–5 business days
Super loads (200,000+ lbs or extreme dimensions): 2–4 weeks (some states require engineering surveys and state police escort)
Multi-state moves: We apply for all permits simultaneously to eliminate cascading delays
Freedom Heavy Haul maintains direct relationships with DOT offices in all 48 contiguous states. Permits that take other carriers 2 weeks typically take us 3–5 days.
Pilot Cars and Escort Vehicles: When You Need Them
Pilot car requirements vary by state and by the dimensions of your load. Here are the general federal guidelines that most states follow:
| Load Width | Pilot Cars Required |
|---|---|
| Under 12 feet | None in most states |
| 12–14 feet | 1 rear pilot car (most states) |
| 14–16 feet | 1 front + 1 rear pilot car |
| Over 16 feet | State police escort often required |
Height requirements: Loads over 14.5 feet typically require a height pole car to check clearances.
State police escort is required for super loads in most states. In Mississippi, Alabama, and several southeastern states, state police must be arranged 2–4 weeks in advance.
Heavy Haul Trailer Types: Choosing the Right One
The trailer determines whether your load moves safely and legally. Using the wrong trailer isn’t just a compliance problem — it’s a safety risk.
RGN (Removable Gooseneck) Trailer
Best for: Tracked equipment (excavators, bulldozers, dozers, cranes), anything that can’t be driven up ramps
How it works: The gooseneck detaches and lowers to the ground, creating a ramp. Equipment drives directly onto the deck — no crane needed for loading.
Deck height: 18–24 inches (lowest of any trailer type)
Weight capacity: 40,000–150,000 lbs depending on axle configuration
Max width: 8.5 ft without permits; commonly hauled up to 14 ft wide with permits
Stretch RGN: The main deck extends hydraulically to accommodate longer loads (wind turbine blades, long beams, extended equipment).
Lowboy Trailer
Best for: Tall equipment where height clearance is the primary concern — large excavators, cranes, mining equipment
Similar to RGN but with a fixed gooseneck (equipment must be loaded by crane or overhead equipment)
Deck height: 18–24 inches
Weight capacity: 40,000–80,000 lbs (standard); heavy-duty lowboys to 150,000 lbs
Flatbed Trailer
Best for: Equipment that doesn’t exceed height limits — steel structures, prefab components, some wheeled equipment, vehicles
Deck height: 48–60 inches
Weight capacity: Up to 48,000 lbs
Note: If height clearance is a concern, a lowboy or RGN is a better choice than a flatbed
Step Deck (Drop Deck) Trailer
Best for: Loads too tall for flatbed but don’t require the ultra-low deck of an RGN or lowboy
Two-level deck — upper deck for standard cargo, lower deck for taller items
Deck height (lower): 36–42 inches
Weight capacity: Up to 48,000 lbs
Conestoga Trailer
Best for: Equipment or cargo that needs weather protection during transport (sensitive machinery, electronics, finished components)
Rolling tarp system covers the entire load — fully enclosed while in transit, fully accessible at delivery
Weight capacity: Up to 48,000 lbs
Multi-Axle / Hydraulic Platform Trailers
Best for: Super loads over 100,000 lbs — large transformers, reactor vessels, industrial equipment
Axle configuration: Customized based on weight — 4, 6, 8, or more axle lines
These are specialized pieces of equipment — not every carrier has them. Freedom Heavy Haul operates multi-axle configurations for loads up to 250,000 lbs.
How Much Does Heavy Haul Trucking Cost?
Transparency is how we do business. Here are the real factors that affect your quote.
Primary Cost Factors
Distance: Longer hauls don’t scale linearly. A 1,000-mile haul costs less per mile than two 500-mile hauls.
Weight and dimensions: The heavier and wider the load, the more expensive permits, the more escorts required, and the more specialized the equipment.
Permits: Typically $15–$200 per state for standard loads. Super load permits can run $500–$2,000+ per state when engineering surveys are required.
Pilot cars: $1.50–$3.00 per mile per escort vehicle. A 500-mile move requiring 2 escorts adds $1,500–$3,000 to the job.
Fuel surcharges: Usually calculated as a percentage of the base rate, adjusted weekly based on DOE fuel index.
Seasonal/route restrictions: Some states restrict oversize movements on holidays or during specific hours. Moves that require nighttime travel can affect total trip time and cost.
Loading and unloading: If loading requires specialized rigging, crane work, or multiple crew members, this is typically a separate line item.
Typical Cost Ranges
Standard heavy haul (80,000–150,000 lbs, under 14 ft wide, under 500 miles): $2,500–$6,000
Large equipment (150,000–250,000 lbs, 14–18 ft wide, multi-state): $8,000–$25,000
Super loads (250,000+ lbs, state police escort required): $20,000–$75,000+
These ranges vary significantly based on route, timing, and market conditions. Get a quote directly — what we quote is what you pay.
How to Prepare Your Equipment for Heavy Haul Transport
Proper preparation reduces risk and speeds up loading. Here’s what our drivers look for:
For tracked equipment:
- Remove any attachments that can be detached (buckets, blades, booms if possible)
- Ensure tracks are in working condition (equipment should drive on/off trailer under its own power where possible)
- Drain fluids to legal levels if required by state regulations
- Lock all cab doors; secure any loose components inside
For wheeled equipment:
- Deflate tires to recommended transport pressure if over-width
- Disable auto-start systems
- Secure all external components (mirrors, lights, any parts that extend beyond the body)
Documentation to have ready:
- Serial number and make/model of equipment
- Accurate weight (not estimated — actual weight from a certified scale if available)
- Overall dimensions: height, width, length including any attachments
- Proof of ownership or authorization to transport
Choosing a Heavy Haul Trucking Company: What to Ask
Not all heavy haul carriers are equal. Before you book, ask:
1. Do you handle your own permitting?
Some carriers broker out permits to third parties, adding delays and markup. We handle all permits in-house with established state DOT relationships.
2. What’s your equipment inventory?
A carrier that “can get any trailer” often means they’re brokering to someone else. We own and operate the equipment we quote you.
3. Are your drivers certified for oversize loads?
Heavy haul drivers need specific training and endorsements. Our drivers are certified, and each load is assigned based on the driver’s specific experience with that equipment type.
4. What’s your claims history?
The right answer isn’t zero — that likely means underreporting. The right answer is what their process is when something does happen.
5. Will you give a fixed price?
Be wary of carriers who quote “estimated” permits and fuel as variables. Get a firm quote that includes permits, escorts, and fuel surcharges.
