When it comes to moving heavy equipment, not just any trailer will do. Whether you’re hauling excavators, bulldozers, or oversized industrial machinery, choosing the right trailer is critical for safety, compliance, and efficiency. In this guide, we’ll break down the best trailer types for hauling heavy equipment, compare their strengths, and help you decide which one fits your needs best.
1. Low Profile Step Deck Trailers: Best for Tall and Heavy Loads
Best for: Excavators, cranes, industrial equipment
Low profile step deck trailers are designed with a deck height even lower than standard step decks, typically running on 17.5″ or 19.5″ tires. This lower deck gives you extra height clearance for oversized machinery while maintaining excellent road stability.
Why choose a low profile step deck?
- Extra low deck height = more clearance for tall equipment
- Lower center of gravity improves balance on long hauls
- Can haul 40,000–80,000 lbs (or more with axle additions)

2. Removable Gooseneck (RGN) Trailers: Built for Easy Loading
Best for: Bulldozers, wheel loaders, pavers
RGN trailers offer a detachable front section that allows equipment to be driven onto the deck easily. This makes them one of the most versatile and popular trailers for oversized loads.
Key advantages:
- Front detaches for drive-on loading
- Can handle up to 150,000 lbs with axle configurations
- Ideal for equipment that can’t be crane-lifted
Pro tip: Be mindful of bridge laws and permits—each U.S. state varies slightly.
3. Standard Step Deck Trailers: For Oversized Equipment Without the Hassle
Best for: Forklifts, medium-sized backhoes, smaller construction gear
Standard step decks (aka drop decks) have an upper and lower deck that allows for taller cargo while staying within legal height limits. They’re great for moderately heavy and tall equipment that doesn’t quite need a full low profile trailer setup.
Step deck benefits:
- Easier loading height than standard flatbeds
- Max legal load height: ~10 feet
- Lower cost and easier to find

4. Flatbed Trailers: The Budget-Friendly Option
Best for: Skid steers, attachments, small generators
For lighter heavy equipment, a standard flatbed trailer may be enough. They’re easy to load, readily available, and cost-effective. But be cautious—height and weight limits are stricter.
Flatbed pros:
- Versatile and widely used
- 48’ and 53’ lengths available
- Ideal for smaller contractors
Trailer Type Comparison Table
| Trailer Type | Load Capacity | Max Height | Loading Method | Best For |
| Low Profile Step Deck | 40k–80k+ lbs | ~10 -11 ft | Rear or crane | Excavators, cranes, tall gear |
| RGN | 40k–150k lbs | ~12 ft | Drive-on (detachable) | Dozers, loaders, large machines |
| Standard Step Deck | ~48k lbs | ~10 ft | Rear ramps/crane | Forklifts, backhoes, midsize gear |
| Flatbed | ~48k lbs | ~8.5 ft | Rear ramps/crane | Light machinery, attachments |
DOT Compliance Tips
- Permits: Oversized or overweight loads typically require special permits. Check federal and state regulations.
- Axle spacing: Be aware of bridge laws that dictate axle group spacing and weight distribution.
- Securing: Heavy machinery must be secured using chains, binders, and edge protectors that meet FMCSA standards.
FAQs
Q: What’s the difference between a low profile step deck and a regular step deck?
A: A low profile step deck has a lower deck height and often smaller tires (17.5″ or 19.5″), allowing taller equipment to be hauled legally.
Q: Do I always need a permit for hauling heavy equipment?
A: Not always. It depends on the equipment’s height, weight, and state regulations.
Q: What’s the most versatile trailer type for mixed equipment?
A: A standard step deck offers flexibility for moderate loads without frequent permit requirements.
Q: Can I use a flatbed to haul a bulldozer?
A: Only if it meets height/weight restrictions. Otherwise, use a low profile step deck or RGN.
Final Thoughts
The best trailer for hauling heavy equipment depends on the load type, dimensions, and frequency of use. If you’re moving tall and heavy machinery regularly, a low profile step deck trailer or RGN is your best bet. For more casual or mixed-use hauling, standard step decks and flatbeds can offer a cost-effective solution.
