Drop Frame ISO Tank Chassis Models
Spread Axle
Drop Frame Chassis
The Spread Axle Drop Frame Chassis (a.k.a. the tandem wide-spread axle chassis) is one of the most popular liquid bulk hauling chassis on the market. This axle configuration provides additional hauling capacity over the closed tandem chassis, without the added weight of a third axle. A spread axle chassis evenly distributes the load weight of the cargo providing a lower center of gravity for bulk liquids during transport.
Tri-Axle Drop Frame Chassis
with Extendable Slider
The Tri-axle Drop Frame Chassis with Extendable Slider (a.k.a. “The Tri-axle Slider Chassis”) provides the same stability for heavy liquid bulk hauling as the standard tri-axle model. This chassis with the slider extended operates at a length of 41-feet. However, with the slider in the closed position, the chassis length is 31-feet requiring less space for parking and ease of storage.
Hi-Lo Drop Frame Chassis
The Hi-Lo Drop Frame Tank Chassis is a drop frame chassis model that is capable of moving two (2) empty or one (1) loaded ISO Tank Container. This optimizes return trips where ISO tank containers are returned empty after delivering a full tank container.
Closed-Tandem Drop Frames
Closed-tandem Drop Frame Chassis have a lower center of gravity than dry box container chassis in order to provide stability for transporting liquid bulk freight. Closed tandem chassis are accepted on nearly all roadways and work well for local driving and in-plant storage.
Tri-Axle Drop Frame Chassis
Tri-axle Drop Frame Chassis transport the heaviest liquid bulk cargo allowed by permit through the addition of a third axle. Tri-axle chassis accommodate heavier loads by distributing the weight over the additional axle, the load-bearing frame, and the tires.
The benefits of hauling heavy payloads must be weighed against the weight of the additional axle during route planning to maintain compliance with bridge laws.
