Understanding Trailer Types and Sizes
Selecting the correct trailer to haul heavy equipment like an 18,000-pound dozer requires balancing length, width, load capacity, and axle configurations. Trailer types vary by cargo needs, with common categories including flatbed, equipment, car hauler, and tilt trailers.
For an 18,000-pound dozer, a 20-foot plus 5-foot (ramp) trailer with dual tandem 10,000-pound axles can be sufficient, provided correct load distribution and adherence to CDL and local regulations. However, some dealers may suggest higher axle ratings in cautious practice. Verifying trailer dimensions, weight ratings, and permits reflecting your specific hauling needs and locations ensures safe and legal operation. Consulting with trailer specialists and considering your vehicle's tow capacity will facilitate selecting the optimal trailer for your heavy equipment transport.
Selecting the correct trailer to haul heavy equipment like an 18,000-pound dozer requires balancing length, width, load capacity, and axle configurations. Trailer types vary by cargo needs, with common categories including flatbed, equipment, car hauler, and tilt trailers.
- Equipment Trailers: Built for heavy machinery, these trailers typically range between 83 inches wide and 20 to 24 feet long. They are reinforced decks with heavy-duty ramps for loading tractors, skid steers, and backhoes.
- Flatbed Trailers: Usually 6 to 8.5 feet wide and 12 to 48 feet long, accommodating oversized cargo.
- Car Hauler Trailers: Designed for vehicles, often 8 to 8.5 feet wide and 16 to 24 feet long.
- Tilt Deck Trailers: Feature a tilting surface for easy wheeled equipment loading, common lengths around 14 to 18 feet.
- Width: Equipment trailers often stick to 6.5 to 8.5 feet wide to comply with road regulations and equipment footprint.
- Length: For an 18,000 lb dozer, trailers generally start at 20 feet in length plus additional length for ramps or tail extensions, such as a 20'+5' configuration.
- Height and Clearance: Load height must meet local legal limits (typically 13.5 to 14 feet max), considering the equipment plus any extensions.
- Axle Ratings: Dual tandem axles rated at 10,000 lbs each are often recommended, but the exact rating should align with total weight distribution and axle spacing.
- Staying under CDL (Commercial Driver’s License) requirements depends on combined vehicle and trailer weight, axle count, and state laws (such as those in Texas).
- Trailer dealers may recommend higher axle ratings for safety margin or legal compliance, considering weight carried and trucking routes.
- Load Distribution on Tow Vehicle: Part of the equipment’s weight is transferred to the truck’s rear axle (tongue weight), influencing the total load on trailer axles.
- Local Regulations: Each state may have unique size and weight limits. It's crucial to check transport permits and comply with size restrictions to avoid fines or operational delays.
- Trailer Build Quality: Heavier-duty trailers are reinforced to manage dynamic loads, vibrations, and frequent loading/unloading stresses.
- Future Flexibility: Consider whether the trailer will also haul other equipment or loads requiring different dimensions or capacities.
- Dual Tandem Axles: Two sets of paired axles supporting trailer load.
- Tongue Weight: The weight exerted by the trailer’s front on the truck hitch.
- CDL: Commercial Driver’s License, required for vehicles/trailers exceeding certain weights.
- Load Capacity: Maximum weight the trailer is rated to carry safely.
- Trailer Deck: Surface on which equipment sits during transport.
