Conex Box on Wheels: Dollies, Trailers & Chassis Explained

A conex box is built to be lifted by cranes and carried by trucks, not rolled around. But there are good reasons to want one on wheels: moving it around a yard, shifting it on a job site, or keeping it mobile for events. There are several ways to do it, each with different limits.

Here's how dollies, trailers and chassis work, and which suits your situation. The right setup depends on the container's size, so compare sizes before you shop for conex box wheels or a conex trailer for sale.

Why put a container on wheels?

• Repositioning a container around a yard or site
• Job sites where storage needs to follow the work
• Events and markets, for mobile booths and storage
• Farms, moving storage between fields
• Temporary placement without a permanent base

Option 1: Container dolly or caster kits

Heavy-duty wheel kits attach to a container's corner castings, turning it into a rolling unit that can be pushed or towed short distances.

Pros

• Fits standard corner castings
• Lets you move a container around a yard
• Removable when not needed

Cons

• For short moves on flat, firm, paved ground only
• Not for road travel
• Weight limits: usually for empty or lightly loaded containers
• Needs a jack or lifting equipment to fit

Best for: shifting smaller, empty containers a short distance on a level yard or warehouse floor.

Option 2: A trailer

A container can be carried on a flatbed, gooseneck or tilt-bed trailer rated for its length and weight.

Pros

• Can travel on the road (within legal limits)
• Can be moved between sites

Cons

• Needs a truck rated to tow the load
• Loading and unloading need equipment, unless it's a tilt-bed trailer
• Securing the container properly is essential
• Weight, height and licensing rules apply

Best for: contractors and farmers who move containers regularly.

Option 3: A container chassis

A chassis is a trailer frame designed specifically to carry containers, with twist locks at the corners. Containers travel on chassis between ports, rail yards and warehouses.

Pros

• Purpose-built and secure
• Quick to connect with twist locks

Cons

• Usually needs a semi-truck
• Most suited to commercial and industrial use

Best for: businesses moving containers between their own sites.

Option 4: A purpose-built mobile unit

Some containers are permanently mounted on a trailer to make mobile offices, kitchens, workshops or event booths.

Pros

• Always ready to move
• Can be set up as a fully fitted mobile space

Cons

• A custom build
• May need trailer registration and inspections

Best for: mobile businesses, events and marketing.

Comparison

Safety first

• Never move a loaded container on caster kits
• Only roll containers on firm, level ground
• Use equipment rated for the weight
• Secure containers on trailers with rated chains or straps
• Check local road rules for weight, height and width

A simpler alternative

For most people, the easiest way to move a container is to call a container hauler with a tilt-bed truck. They can lift it from one spot and set it down in another, without you buying wheels or trailers.

Which size moves best?

Smaller containers, such as 8ft and 10ft units, are the easiest to put on wheels and move around a site. A 20ft can be moved on a suitable trailer. A 40ft usually needs a professional hauler.

Questions to ask before buying wheels or a trailer

• How often will I actually move the container?
• How far, and over what kind of ground?
• Will it ever travel on public roads?
• Will it be empty or loaded when it moves?
• Do I have equipment to lift it onto wheels or a trailer?
• Would hiring a hauler for occasional moves cost less?

If you'll only move it once or twice, a hauler with a tilt-bed truck is almost always simpler and cheaper.

FAQ

Can I put wheels on a shipping container?

Yes, with heavy-duty caster kits that attach to the corner castings, for short moves on firm ground.

Can I tow a container on the road with wheels attached?

Not with caster kits. For road travel, use a rated trailer or chassis.

What's a conex trailer?

Usually a trailer used to carry a conex box, or a container permanently mounted on a trailer to make a mobile unit.

How do I move a container a short distance?

On a level, paved yard, a caster kit can work for an empty container. Otherwise, hire a hauler with a tilt-bed truck.

Can a loaded container be moved on wheels?

It's not recommended. Empty the container first to stay within equipment limits and stay safe.
