How to Ship a Cold Planer Milling Machine: Complete Transport Guide

Cold Planer Dimensions and Weight

Cold planers vary significantly in size depending on the milling drum width and machine class. Here are typical specifications for common models:

Machine Class	Operating Weight	Milling Width	Transport Width	Transport Height
Small/compact (e.g., Wirtgen W 50)	20,000–35,000 lbs	20 inches	5–6 ft	8–9 ft
Mid-size (e.g., Cat PM310, Wirtgen W 100)	50,000–65,000 lbs	39–42 inches	8–9 ft	10–11 ft
Large (e.g., Cat PM620, Wirtgen W 200)	70,000–90,000 lbs	79–84 inches	10–12 ft	11–13 ft
Extra-large (e.g., Wirtgen W 250)	90,000–120,000+ lbs	98 inches	12–14 ft	12–14 ft

Large and extra-large cold planers almost always exceed standard legal width limits (8.5 ft) and frequently exceed standard weight limits (80,000 lbs GVW), requiring oversize and overweight permits in every state they transit.

Trailer Requirements for Cold Planers

Cold planers require specialized trailers due to their weight, low ground clearance, and wide milling drums:

• RGN (Removable Gooseneck) trailer: The standard choice for mid-size and large cold planers. The detachable gooseneck allows the trailer to be lowered to ground level for drive-on loading, which is critical for machines with low ground clearance (often 12–18 inches). Multi-axle RGN configurations (3-axle, 4-axle, 5-axle) are used for the heaviest machines to distribute weight within bridge formula limits.
• Lowboy trailer: Suitable for smaller cold planers that can be loaded with a crane or forklift. Fixed-neck lowboys are less flexible for loading but may be appropriate for machines that can be lifted.
• Specialized multi-axle trailers: For extra-large cold planers over 100,000 lbs, specialized multi-axle trailers (Goldhofer, Scheuerle, or similar) may be required to distribute weight across enough axles to comply with bridge formula requirements.

Loading a Cold Planer: Critical Procedures

Loading a cold planer is one of the most technically demanding loading operations in heavy equipment transport. Key considerations include:

1. Level ground: The loading area must be level and firm. Cold planers have a high center of gravity when the conveyor is raised, making them susceptible to tipping on uneven ground.
2. Conveyor positioning: The front conveyor should be folded or lowered to its minimum transport height before loading. On some models, the conveyor must be removed entirely for transport.
3. Drive-on loading: Most large cold planers are driven onto the RGN trailer under their own power. A spotter is required to guide the operator, and the trailer must be properly blocked and stabilized before the machine drives on.
4. Weight distribution: The machine must be centered on the trailer to maintain proper axle weight distribution. Offset loading can cause axle weight violations even if total GVW is within limits.
5. Securement: Heavy-duty chains (minimum 1/2-inch Grade 80) are used at manufacturer-designated tie-down points. The milling drum housing and crawler frames are the primary securement points on most models.

Permit Requirements for Cold Planers

Most mid-size and large cold planers require both oversize and overweight permits:

• Oversize permits: Required when load width exceeds 8.5 ft or height exceeds 13.5 ft (varies by state). Large cold planers (10–14 ft wide) require oversize permits in every state.
• Overweight permits: Required when GVW exceeds 80,000 lbs. Most large cold planers (70,000–90,000 lbs machine weight plus trailer weight) require overweight permits.
• Superload permits: Required in most states when GVW exceeds 150,000 lbs or when width exceeds 14–16 ft (varies by state). Superload permits require route surveys, engineering review, and often utility coordination for overhead line clearances.
• Pilot cars: Required for loads over 14 ft wide in most states; two pilot cars required for loads over 16 ft wide in many states. Police escorts may be required in some jurisdictions for very wide loads.

Cost Factors for Cold Planer Transport

• Machine size: Larger machines require more axles, more expensive trailers, and more complex permits — all of which increase cost significantly.
• Permit complexity: Superload permits can cost $1,000–$5,000+ per state depending on route survey requirements.
• Pilot cars: Two pilot cars for a 12-ft-wide machine on a 500-mile route can add $3,000–$6,000 to total cost.
• Loading complexity: If the conveyor must be removed or the machine requires specialized loading equipment, add $500–$2,000 for loading labor.
• Transit time: Superload moves often travel at reduced speeds (35–45 mph) and may be restricted to daylight hours, extending transit time to 7–14 days for cross-country moves.
