A drop-frame chassis is a type of container chassis characterized by its lower center deck. This chassis is primarily used for safely and stably transporting ISO tank containers and other heavy, dense cargo. The drop in the frame lowers its center of gravity, improving stability, reducing rollover risk, and ensuring compliance with heavy-load regulations.
When choosing a drop-frame chassis, it is important to consider its axle configuration for optimal cargo transport. Each configuration has its fuel efficiencies and load limits, which means they may be better suited for certain containers.
Types of Drop-Frame Chassis Axle Configuration
Closed Tandem Chassis
The closed tandem chassis is the industry standard and is considered the most common axle configuration for drop-frame chassis. This type of container chassis has two axle sets, providing a longer chassis frame and increased strength and stability for moving liquid cargo. Due to its lower ground clearance, closed tandem configurations are best for short hauls.
Tandem Wide Spread Axle Chassis
The spread axle chassis has a greater distance between its two rear axles, giving it additional hauling power without the added weight of a third axle. This chassis axle configuration evenly spreads the weight of the load, improving flexibility and stability during transport.
Tri-Axle Chassis
Tri-axle drop-frame chassis have a third axle and four additional tires, allowing for increased weight distribution over the load-bearing frame and tires. This allows the chassis to carry heavier loads.
How to Select Drop-Frame Axle Configuration
Cargo and Weight
Before deciding on a chassis axle configuration, it is important to understand the type of cargo the chassis will haul and how heavy it is.
For generally heavy loads, tri-axle configurations are recommended to provide even distribution and stability. Moreover, tri-axle chassis are necessary to legally and safely move heavy containers.
For bulk liquids, tandem wide spread axle chassis are designed to move this type of cargo. These chassis ensure liquid cargo is stable during transport.
Operational Needs and Road Conditions
The tri-axle and tandem wide spread axle chassis are designed for long-haul travel and uneven cargo, as the setup allows for stability and reduced tire wear across a larger footprint. Additionally, consider how the chosen configuration will affect turning radius and space requirements, especially for tri-axle setups.
For road conditions, any option can perform well on a standard highway. However, hilly or unpaved routes may need heavier-duty or high-capacity axles to handle greater torque and strain.
