OCT_Lightweight Chassis Model Differences

When customers ask us about 40’ lightweight chassis, we have numerous options to present to them.  We have models with Super Single Tires, Dual Radial Tires, Spread Axles with different spread lengths, and even options within those spread lengths.  Hauling “heavy” containers- specifically 40’ containers in this case- why we have a 41’ AND a 40’ chassis length.  There are a few different reasons why have those model lengths, and hopefully this should help answer that.

One of the major differences in this length is the added flexibility for the types of trucks or tractors to pull these chassis.  Owner/Operators make up a huge portion of truck fleets across the country, and not all of these trucks are alike within the same fleet.  There are different wheel base lengths and weights these tractors, which of course contribut the GVWR (Gross Vehicle Weight Rating) of the entire vehicle- while the complete package (truck, trailer, container, load) are going over the road.  In order to be less restrictive on the type of truck that Owner/Operators use to pull these over the road legally.

When looking at Federal Bridge Law- in order to carry 84,000 lbs over 5 axles- while referring to either “tandem” or “tandem spread axle” lightweight chassis- a total of 58 feet in total vehicle length is needed to meet that requirement.  Sometimes that extra 1 foot in chassis length is excruciatingly critical to hauling a “over the road heavy load” legally.

While looking at the 41’ chassis to some of our other 40’ chassis models, our customers ask about the weight differences between these models.  Is there a weight difference between our 40’ and 41’ lightweight chassis models?  Yes.  We are adding another foot of steel to the chassis, bottom line.  That being said, we are able to mitigate the extra weight by using lightweight components in the hubs, drums, and tires so the difference becomes increasingly nominal between the two.

At National Chassis, we want our customers equipped with the RIGHT equipment to meet their customers demands safely and legally.  If you have any questions about lightweight chassis, or any other model chassis, please don’t hesitate to contact us, any member of our staff would be more than happy to assist you.  We would love to hear from you.
