1. Standard Container Chassis
The Standard Container Chassis is the workhorse of the container transport world. It’s a fixed-frame trailer specifically built to carry ISO containers on roads, ports, and intermodal yards.
If you’re hauling standard-sized freight containers and your routes are predictable, this is likely your go-to setup.
Common Sizes Supported:
- 20-foot containers
- 40-foot containers
- Some models can handle 45-foot with modifications
Key Features
Let’s keep it real, this chassis type isn’t flashy, but it gets the job done. Here are six core features that matter:
- Fixed-length steel frame
- Twist-lock mechanisms
- Basic tandem axle design
- DOT-compliant lighting and brakes
- Spring or air suspension
- Tractor compatibility
Use Cases
Standard chassis are perfect for businesses that move general freight on regular routes. If you’re in:
- Logistics and 3PL services
- Port-to-warehouse transport
- Retail and consumer goods distribution
- Manufacturing-to-distribution operations
I’ve seen entire retail chains run just fine with a fleet of standard chassis. One client ran cross-state deliveries from port to store distribution centers and never needed anything else.
Benefits of Using Standard Chassis
Let’s talk about why this option still dominates the yard:
- Cost-Effective: Scale up your fleet without breaking the bank
- Low Maintenance: Fewer moving parts means fewer headaches
- Widely Available: Easy to find, easy to replace
- Great for General Freight: If it fits, it ships, no extras needed
- Driver-Friendly: Straightforward to hook up and go
- Intermodal Ready: Built for smooth transitions between rail, road, and port
Limitations
Now, here’s where you need to be careful:
- No Flexibility: Fixed frame means no sliding or extending
- Not For Heavy Cargo: Exceeds weight limits? You’ll need a stronger build
- Basic Use Only: Doesn’t support specialized cargo like tankers or reefers
- Limited on Terrain: Better suited for smooth highways than job sites or backroads
I once had a client in the food distribution space who used standard chassis for years. But when they expanded into bulk refrigerated loads, the limitations hit hard. They had to quickly upgrade their fleet to drop frames and goosenecks to stay compliant and on schedule.

2. Extendable Chassis (Slider Chassis)
An Extendable Chassis, also called a Slider Chassis, is a versatile trailer that can adjust its length to accommodate different container sizes.
If your operations involve handling both 20-foot and 40-foot containers, or switching frequently between them, this chassis type can save you serious time and hassle.
Common Sizes Supported:
- 20-foot containers
- 40-foot containers
- 45-foot containers (select models)
Key Features
You need gear that works as hard as you do—this chassis adapts fast and performs in real-world conditions:
- Sliding frame mechanism
- Locking pin system
- Heavy-duty steel construction
- Multi-position twist locks
- Air ride or spring suspension
- Legal compliance for multiple states
Use Cases
Extendable chassis are built for fast-paced, container-switching environments. If you’re regularly loading and unloading containers of different lengths, this is your smart solution.
You’ll see these used by:
- Intermodal transport providers
- Drayage and short-haul operators
- Freight forwarders and depots
- Retail distribution hubs with variable imports
A transportation client of mine once told me this was the “Swiss army knife” of their fleet. They didn’t have to guess which chassis to send out anymore, it worked for nearly every container.
Benefits of Using Extendable Chassis
If flexibility is a core need in your business, here’s why this chassis earns its place:
- One chassis, multiple uses
- Improves asset utilization
- Reduces repositioning costs
- Boosts operational efficiency
- Minimizes driver delays

Limitations
While flexible, it’s not the perfect fit for every situation. Watch out for these potential drawbacks:
- More Moving Parts: Means higher maintenance compared to standard chassis
- Heavier tare Weight: May reduce payload capacity slightly
- Requires Driver Training: To properly extend, lock, and inspect the frame
- May Not Support Overweight Loads: Especially in more basic models
One client learned the hard way when their team used it for overweight steel coil containers. It flexed under pressure, literally. They quickly upgraded to tri-axles for that route.

3. Gooseneck Chassis
A Gooseneck Chassis features a lowered front section, known as the gooseneck, that allows high-cube containers to sit lower to the ground.
This clever design helps meet height clearance limits without sacrificing container space, especially for 9’6″ tall containers.
Common Sizes Supported:
- 20-foot high-cube containers
- 40-foot high-cube containers
- 45-foot containers (depending on model)
Key Features
This chassis type is built for taller loads and serious road performance. If your cargo needs more room up top, this is your fix:
- Lowered Gooseneck Frame: Allows taller containers to ride lower
- High-Cube Container Support: Prevents over-height violations
- Heavy-Duty Steel Construction: Built to handle heavy intermodal wear
- Standard Twist-Lock System: Keeps containers secure during transport
- Tandem or Tri-Axle Options: Available for different load requirements
- DOT Height Compliance: Helps meet bridge clearance laws in multiple states
Use Cases
If you’re in an industry moving tall, space-consuming containers, this chassis pays off quickly. It’s especially critical in operations where high-cube freight is standard.
Common users include:
- Import/Export Companies Hauling High-Cube Cargo

As with all equipment, this chassis has trade-offs. Be aware of:
- Higher Upfront Cost: More specialized design = more investment
- Limited Versatility: Not ideal for standard-height containers only
- Slightly Heavier: The gooseneck frame adds extra steel and weight
- Not Built for Non-Containerized Cargo: Strictly for container hauling
I’ve seen companies try to use goosenecks for general flat loads, but it’s not made for that. One logistics company quickly pivoted to flatbeds for flexibility, keeping their goosenecks strictly for overseas retail and port hauls.

4. Drop Frame Chassis
A drop-frame chassis, also known as a drop-deck chassis, features a lowered mid-section that sits below the standard chassis height. This design allows extra vertical clearance for tall or bulky containers, making it ideal when you need every inch of space to stay compliant or protect sensitive cargo.
Common Sizes Supported:
- 40-foot high-cube containers
- 45-foot containers

- Single-Use Design: Only supports cylindrical ISO tank containers
- Higher Investment Cost: A Specialized build means higher upfront pricing
- Requires Skilled Handling: Improper loading or inspection = high risk
- Not Ideal for Dry or General Freight: Can’t be repurposed for standard containers
One client once tried to use a tank chassis for a 20′ dry container during a shortage, let’s just say it didn’t end well. Fit issues, wasted time, and ultimately a second dispatch to fix it.

7. Flatbed Chassis (Combo Use)
A Flatbed Chassis, also known as a Combo Chassis, is a dual-purpose trailer that functions as both a container chassis and a flatbed trailer.
It’s built for operations that need to carry containers one day and oversized, irregular, or palletized cargo the next. Versatility is its biggest strength.
Common Sizes Supported:
- 20-foot containers
- 40-foot containers
- Palletized or breakbulk cargo up to standard flatbed length (typically 40–45 feet)
Key Features
This is the Swiss Army knife of chassis. When you need flexibility without switching trailers, this is what you hook up:
- Flat, Open Deck Design: Hauls containers or general freight with ease
