How to Ship a Straddle Carrier or Container Handler: Transport Guide

What Is a Straddle Carrier?

A straddle carrier (also called a van carrier or straddle truck) is a self-propelled machine used in container terminals and intermodal yards to lift, transport, and stack ISO shipping containers. The machine straddles the container from above, grips it with a spreader bar, and carries it suspended beneath the frame. Common applications include port container yards, rail intermodal terminals, and large industrial storage facilities.

For transport purposes, straddle carriers present unique challenges: their tall, wide frame cannot be moved intact on public roads without significant disassembly, and their weight often triggers superload permit requirements.

Typical Dimensions and Weight

Specification	Typical Range	Transport Impact
Operating Height	20–30 ft (6–9 m)	Must be disassembled for road transport
Operating Width	16–20 ft (4.9–6.1 m)	Far exceeds 8.5 ft legal width; superload permit likely
Operating Weight	17–50 tons (34,000–110,000 lbs)	Multi-axle trailer required; may trigger superload
Transport Width (disassembled)	10–14 ft depending on model	Still oversize; escort vehicles required
Transport Height (disassembled)	13–16 ft	Route survey required for loads over 13.5 ft

Disassembly Requirements for Road Transport

Straddle carriers cannot be transported intact on public roads. The following components are typically removed or folded before transport:

• Upper frame / portal structure: The tall vertical legs must be removed or folded down. This is the most labor-intensive part of the disassembly and requires a crane and specialized rigging crew.
• Spreader bar: Removed and shipped separately on a flatbed trailer.
• Cab: May need to be removed or lowered depending on the model.
• Outriggers and stabilizers: Folded or removed to reduce transport width.

Disassembly and reassembly typically requires 1–2 days at each end of the move and must be performed by technicians familiar with the specific machine model. Factor this into your project timeline.

Trailer and Permit Requirements

Even after disassembly, straddle carrier components are heavy and wide. Transport requirements include:

• Main frame/chassis: Multi-axle RGN or Goldhofer modular trailer; 3–5 axles depending on weight
• Upper frame sections: Flatbed or step deck; may require oversize permits if sections exceed 8.5 ft wide
• Spreader bar: Standard flatbed if under 8.5 ft wide; step deck if taller than 8.5 ft

For machines over 100,000 lbs GVW, a superload permit is required in most states. Superload permits require a route survey, engineering analysis of bridge capacities, and coordination with state DOT offices — a process that can take 2–4 weeks. Plan accordingly.

Port-to-Port and Terminal Moves

Many straddle carrier moves are port-to-port or terminal-to-terminal relocations — for example, moving a machine from the Port of Houston to the Port of Savannah, or from a decommissioned intermodal yard to a new facility. These moves often involve:

• Coordination with port authority for access and loading/unloading
• Crane rental at both origin and destination for disassembly/reassembly
• Multi-truck convoy for large machines (main frame + upper structure + spreader = 3+ loads)
• Export documentation if the machine is being shipped overseas after road transport to port
