How to Ship a Wheel Excavator: Complete Transport Guide
Wheel excavators — also called rubber tire excavators — combine the digging power of a tracked excavator with the road mobility of a wheeled machine, making them popular in urban construction, utility work, and road maintenance. Their unique configuration creates specific transport challenges: unlike tracked excavators that must be loaded onto trailers, wheel excavators can often drive short distances under their own power, but their height, weight, and boom configuration still require careful planning for highway transport. This guide covers everything you need to know about shipping a wheel excavator safely and legally.
Wheel Excavator Size and Weight Ranges
Wheel excavators vary significantly in size depending on the manufacturer and model. Understanding your machine's specifications is the first step in planning transport:
| Size Class | Operating Weight | Typical Width | Transport Height (boom lowered) |
|---|---|---|---|
| Small (e.g., Volvo EW60, Kubota KX080W) | 12,000–20,000 lbs | 6'–7'6" | 8'–9'6" |
| Mid-size (e.g., Caterpillar M315, Liebherr A914) | 20,000–45,000 lbs | 7'6"–9' | 9'6"–11' |
| Large (e.g., Liebherr A924, Caterpillar M322) | 45,000–80,000 lbs | 9'–10'6" | 10'–12' |
Always obtain the exact operating weight, transport dimensions (with boom and arm in travel position), and outrigger/stabilizer width from the manufacturer's spec sheet before requesting a transport quote. Estimated weights can lead to incorrect trailer selection and permit errors.
Trailer Selection for Wheel Excavators
The right trailer depends on the machine's weight and transport height:
- Flatbed (48'–53'): Suitable for small wheel excavators under 12,000–15,000 lbs that fit within legal height limits (13'6" in most states). The machine must be able to drive onto the flatbed via ramps.
- Step-deck (drop-deck): Provides approximately 20–24 inches of additional height clearance compared to a flatbed. Used for mid-size wheel excavators where the boom-lowered height exceeds flatbed limits but stays within step-deck clearance.
- Lowboy / RGN (Removable Gooseneck): Required for large wheel excavators over 40,000 lbs or machines with transport heights exceeding step-deck clearance. The RGN's detachable gooseneck allows the machine to drive onto the trailer at ground level — particularly useful for wheel excavators that can self-propel.
Preparing a Wheel Excavator for Transport
Proper preparation prevents damage and ensures compliance with securement regulations:
- Retract and position the boom: Lower the boom and curl the arm and bucket tight against the machine. Position the boom over the front or rear of the trailer as directed by the carrier to minimize the transport envelope and stabilize the center of gravity.
- Lock the swing: Engage the swing lock to prevent the upper structure from rotating during transit. Most wheel excavators have a dedicated swing lock pin or lever.
- Secure the outriggers/stabilizers: Retract all outriggers and stabilizers fully and pin them in the travel position. Verify that no hydraulic lines are under tension.
- Check tire pressure: Unlike tracked excavators, wheel excavators have pneumatic tires that must be at the correct pressure for transport. Under-inflated tires can cause instability on the trailer.
- Clean the undercarriage and tires: Remove mud, rocks, and debris from tires and undercarriage to prevent road hazards and allow accurate condition documentation.
- Document condition: Photograph all sides, the boom, arm, bucket, and any existing damage before handover to the carrier. This establishes a baseline for any damage claims.
Securement Requirements (49 CFR 393.130)
Federal regulations require specific securement for heavy machinery weighing 10,000 lbs or more:
- Minimum of four tie-down chains or straps attached to designated tie-down points on the machine's frame
- Chains must be rated for the load and attached as close to the front and rear of the machine as possible
- The boom must be secured independently to prevent movement — a loose boom can shift the center of gravity and cause instability
- Wheel chocks must be placed against the tires to prevent rolling
Permit Requirements for Wheel Excavators
Most mid-size and large wheel excavators will exceed at least one legal limit and require oversize/overweight permits:
- Width: Machines over 8'6" wide require a permit in all states. Many mid-size and large wheel excavators exceed this threshold.
- Height: Transport height (boom lowered) for mid-size and large machines often exceeds 13'6", requiring height permits.
- Weight: Large wheel excavators over 40,000 lbs, combined with trailer weight, frequently approach or exceed the 80,000 lb GVW limit.
Permits must be obtained for every state the load will transit. IronHaul handles all permit acquisition as part of the transport package.
Self-Propelled Loading: A Key Advantage
One of the practical advantages of wheel excavators over tracked machines is their ability to self-propel onto trailers. This eliminates the need for a crane or forklift for loading in most cases, reducing setup time and cost. However, the carrier must confirm that the delivery site has adequate space for the trailer to position and that the ground is stable enough to support the machine during loading and unloading.

Common questions
Can a wheel excavator drive onto the trailer under its own power?
Yes, in most cases. Wheel excavators are self-propelled and can drive onto RGN or lowboy trailers at ground level, eliminating the need for a crane or forklift. The carrier must confirm adequate space and stable ground at the loading site.
What trailer is needed for a large wheel excavator (45,000–80,000 lbs)?
Large wheel excavators typically require a lowboy or RGN (Removable Gooseneck) trailer. The RGN's detachable gooseneck allows ground-level loading, and the low deck height accommodates the machine's transport height.
Do wheel excavators require oversize permits?
Most mid-size and large wheel excavators exceed at least one legal limit (width, height, or weight) and require oversize/overweight permits in every state they transit. IronHaul handles all permit acquisition.
How should the boom be positioned for transport?
Lower the boom and curl the arm and bucket tight against the machine. Position the boom over the front or rear of the trailer as directed by the carrier to minimize the transport envelope and stabilize the center of gravity. Engage the swing lock to prevent upper structure rotation.
What is the typical weight range for wheel excavators?
Small wheel excavators weigh 12,000–20,000 lbs; mid-size machines run 20,000–45,000 lbs; large models can reach 45,000–80,000 lbs. Always obtain the exact operating weight from the manufacturer's spec sheet before requesting a transport quote.
