How to Ship a Straddle Carrier: Complete Heavy Haul Transport Guide
Straddle carriers are among the most challenging pieces of port and intermodal equipment to transport on public roads. These massive machines — typically weighing 80,000 to 120,000 lbs and standing 42 to 51 feet tall in operating position — handle approximately 85% of container movements in major ports worldwide. Moving them between facilities requires partial disassembly, specialized trailers, multi-state permits, and professional rigging. This guide explains the full process.
Straddle Carrier Dimensions and Weight
Straddle carriers are purpose-built for port and intermodal container handling. Their dimensions make them among the most challenging machines to transport on public highways:
| Specification | Typical Range |
|---|---|
| Operating Height | 42–51 ft (12.7–15.6 m) |
| Operating Width | 15–17 ft (4.6–5.2 m) |
| Operating Length | 30–45 ft (9–14 m) |
| Weight | 80,000–120,000 lbs (36–54 metric tons) |
| Stacking Capacity | 1-over-2 to 1-over-3 (3–4 containers high) |
These dimensions far exceed standard highway limits in every category — width, height, and weight — making partial disassembly mandatory for road transport.
Why Disassembly Is Required
A straddle carrier in operating configuration is 15–17 ft wide and 42–51 ft tall — both far beyond the 8.5 ft width and 13.5 ft height limits for standard highway travel. To comply with road regulations, the machine must be partially disassembled before transport. Typical disassembly steps include:
- Separating the upper structure (cab and spreader assembly) from the lower portal frame
- Removing the spreader beam and any telescoping components
- Disconnecting hydraulic lines between upper and lower sections
- Removing any external lighting, antennas, or protrusions that add to overall width or height
Even after disassembly, individual components typically exceed 12–14 ft in width, requiring oversize permits and pilot car escorts. The number of trailer loads required depends on the specific model — most straddle carriers require 2–4 separate loads.
Trailer Selection
Each component of a disassembled straddle carrier requires a specialized trailer:
- RGN (Removable Gooseneck): Used for the lower portal frame, which is the heaviest component. The RGN's low deck height (18–20 inches) accommodates the frame's height after disassembly.
- Lowboy / Double Drop: For the upper structure and cab assembly. The double-drop configuration provides maximum clearance for tall components.
- Multi-Axle Trailer: For components exceeding 80,000 lbs, additional axles are required to distribute weight within legal axle limits. Hydraulic multi-axle trailers (Goldhofer, Scheuerle) are commonly used for the heaviest components.
- Flatbed or Step Deck: For smaller components — spreader beams, hydraulic cylinders, and accessories — that can be transported separately.
Permit Requirements
Straddle carrier transport almost always qualifies as a superload — loads exceeding 150,000 lbs or 16 ft wide. Superload permits require:
- Bridge engineering review in most states (7–21 days processing time)
- State DOT route approval with specific road restrictions
- Multiple pilot car escorts (front and rear) in most jurisdictions
- Travel restricted to daylight hours and specific days of the week in many states
- Permit fees of $500–$5,000+ per state depending on load dimensions
Plan for 3–6 weeks of lead time for superload permit coordination across multiple states. IronHaul's permit team has experience with superload moves and can manage the full process.
Rigging and Loading Requirements
Loading a straddle carrier component requires professional rigging:
- Crane or gantry system rated for the component weight (50,000–80,000 lbs for the portal frame)
- Certified riggers with experience in port equipment disassembly
- Manufacturer-specific lift points and rigging diagrams (consult the OEM manual)
- Blocking and cribbing to stabilize components on the trailer deck
- Chain tie-downs rated for the load weight, attached to designated structural points
Cost Factors for Straddle Carrier Transport
Straddle carrier moves are among the most expensive heavy-haul projects due to their complexity. Key cost drivers: professional disassembly and reassembly labor ($5,000–$20,000+), crane/rigging for loading and unloading, multiple specialized trailers, superload permit fees per state, multiple pilot car escorts, and extended transit times due to travel restrictions. Total project costs for a cross-country straddle carrier move can range from $50,000 to $200,000+ depending on distance and complexity.

Common questions
Does a straddle carrier have to be disassembled for road transport?
Yes. Straddle carriers are 15–17 ft wide and 42–51 ft tall in operating position — far beyond highway limits. Partial disassembly into 2–4 separate loads is required for road transport.
How many trucks are needed to move a straddle carrier?
Most straddle carriers require 2–4 separate trailer loads after disassembly. The exact number depends on the specific model and how it can be broken down into transportable components.
How long does it take to get permits for a straddle carrier move?
Straddle carrier components typically qualify as superloads, requiring bridge engineering review. Plan for 3–6 weeks of lead time for multi-state permit coordination.
What does it cost to ship a straddle carrier?
Total project costs vary widely based on distance and complexity. Cross-country moves typically range from $50,000 to $200,000+ including disassembly, rigging, permits, and transport. Contact IronHaul for a project-specific assessment.
Can IronHaul coordinate the disassembly and reassembly of a straddle carrier?
Yes. IronHaul can coordinate with certified rigging crews and port equipment specialists for disassembly at origin and reassembly at destination. We manage the full project from start to finish.
