How to Ship a Soil Compactor or Padfoot Roller
Soil compactors and padfoot rollers are essential earthmoving machines that present unique transport challenges due to their wide drum widths, articulated frames, and heavy operating weights. From compact tandem rollers under 10,000 lbs to massive landfill compactors exceeding 100,000 lbs, the right trailer and preparation approach varies significantly by machine type. This guide covers the key considerations for shipping smooth-drum rollers, padfoot compactors, and landfill compactors safely and efficiently.
Types of Compactors and Their Transport Characteristics
The compactor category includes several distinct machine types, each with different transport requirements:
- Smooth-Drum Vibratory Rollers: Used for asphalt and soil compaction. Drum widths typically range from 54 to 84 inches (4.5–7 ft). Operating weights range from 8,000 lbs (compact single-drum) to 35,000 lbs (large tandem). Most ship on flatbeds or step decks.
- Padfoot / Sheepsfoot Rollers: Used for soil and clay compaction. Similar drum widths to smooth-drum rollers but with protruding pads on the drum surface. Operating weights typically 15,000–50,000 lbs. Ship on step decks or lowboys depending on size.
- Pneumatic Tire Rollers: Used for asphalt finishing. Multiple rubber tires instead of a drum. Operating weights typically 10,000–35,000 lbs. Often ship on flatbeds or step decks.
- Landfill Compactors: Massive machines with steel cleated wheels used at landfill sites. Operating weights typically 80,000–120,000 lbs. Require heavy lowboys or multi-axle configurations.
- Soil Stabilizers / Reclaimers: Large machines with rotating drum cutters. Operating weights typically 40,000–80,000 lbs. Require lowboys or RGN trailers.
Weight and Dimension Ranges by Machine Type
| Machine Type | Operating Weight | Drum/Machine Width | Typical Trailer |
|---|---|---|---|
| Compact Tandem Roller | 8,000–15,000 lbs | 54–66 in (4.5–5.5 ft) | Flatbed or Step Deck |
| Mid-Size Single Drum | 15,000–30,000 lbs | 66–84 in (5.5–7 ft) | Step Deck or Lowboy |
| Large Padfoot Roller | 30,000–55,000 lbs | 72–96 in (6–8 ft) | Lowboy / RGN |
| Landfill Compactor | 80,000–120,000 lbs | 96–120 in (8–10 ft) | Multi-Axle Lowboy |
The Critical Measurement: Drum Width and Permit Thresholds
The drum width is often the deciding factor for whether a compactor requires oversize permits. The federal standard width limit is 8.5 ft (102 inches). Many mid-size and large compactors have drum widths at or near this threshold:
- Drums under 102 inches wide: May ship without oversize width permits (still need weight permits if over 80,000 lbs GVW)
- Drums 102–144 inches wide: Oversize width permit required; one pilot car typically required for widths over 12 ft
- Drums over 144 inches wide: Two pilot cars required in most states; some states require law enforcement escort
Always measure the machine in its final shipping configuration — with ROPS folded (if applicable) and any accessories removed — before requesting a quote.
Articulation Lock: A Critical Safety Requirement
Most soil compactors and rollers have articulated frames that allow the machine to steer. During transport, the articulation joint must be locked in a straight position using the manufacturer's factory articulation lock pins or chains. Failure to lock the articulation joint can allow the machine to fold during transport, creating a serious safety hazard and potentially damaging the trailer and machine.
Before loading, verify that the articulation lock is engaged and that the machine cannot pivot at the frame joint. If the factory lock pins are missing, chains can be used to secure the frame in a straight position, but this should be confirmed with the carrier before loading.
Preparing a Compactor for Transport
- Clean the drums and undercarriage: Remove accumulated soil, clay, and debris. Loose material can shift during transport, create road hazards, and obscure tie-down points and pre-existing damage.
- Lock the articulation joint: Engage factory lock pins or secure with chains before loading.
- Fold ROPS if applicable: Many compactors have foldable ROPS (Roll-Over Protection Structure) that can reduce transport height. Fold and secure before measuring final transport height.
- Measure in transport configuration: Take final height, width, and length measurements with the machine in its shipping configuration (ROPS folded, accessories removed) to ensure accurate permit applications.
- Disclose non-operational status: If the machine cannot be driven, a crane or winch is required for loading. Disclose this when requesting a quote.
Tie-Down and Securement
Compactors must be secured per 49 CFR 393.130 for machinery over 10,000 lbs. Key securement points include the machine's frame, tow hooks, and designated lashing eyes. Never attach chains to the drum surface, hydraulic cylinders, or ROPS structure. Use Grade 70 or Grade 80 chains with working load limits appropriate for the machine's weight. Drum surfaces should be protected from chain contact with rubber or wood blocking.

Common questions
What trailer do I need to ship a large padfoot roller?
Large padfoot rollers (30,000–55,000 lbs) typically require a lowboy or RGN trailer. The RGN's removable gooseneck allows the machine to drive directly onto the deck. Smaller padfoot rollers (under 25,000 lbs) may ship on a step deck depending on height.
Do I need to lock the articulation joint before shipping a compactor?
Yes — this is a critical safety requirement. The articulation joint must be locked in a straight position using factory lock pins or chains before loading. An unlocked articulation joint can allow the machine to fold during transport, creating a serious safety hazard.
Does drum width affect permit requirements?
Yes. The drum width is often the deciding factor for oversize permits. Drums under 102 inches (8.5 ft) wide may not require oversize width permits. Drums over 102 inches require oversize permits; widths over 12 ft require pilot cars. Always measure in the final shipping configuration.
How do I prepare a compactor for transport?
Clean the drums and undercarriage, lock the articulation joint, fold the ROPS if applicable, and measure the machine in its final shipping configuration. Disclose non-operational status at booking if the machine cannot be driven onto the trailer.
Can a landfill compactor be shipped on a standard lowboy?
Most landfill compactors (80,000–120,000 lbs) exceed the capacity of a standard 3-axle lowboy and require a heavy multi-axle lowboy configuration. These moves also require oversize/overweight permits and may require superload permits for the heaviest machines.
