The method for solving for the hyperstactic situation is rather complicated due to geometry issues and my guess is that there is some rule of thumb or simplification to solve this. L spacing in feet between the outer axles of any two or more consecutive axles. However, differently from the past calculations I've made this one is an hyperstactic problem as I have three reaction forces. The formula is as follows: W the maximum weight in pounds that can be carried on a group of two or more axles to the nearest 500 pounds (230 kg). I have all the weights and the location of all centres of gravity of the semi trailer unit and the supplier information of the tractor unit loads on both front and rear axles. Otherwise, you’ll overload the tow vehicle rear axle and unload the tow vehicle front axle. Weight-distribution hitches are required by most pickup truck manufacturers once the trailer weight exceeds 5,000-6,000 lbs. Whether you’re buying, selling or using trucks, speccing safe, legal and efficient. However this time I've been asked to perform it for a tanker trailer truck, which is a tractor unit (1 steer axle at front and two driving axles in tandem at the rear) and the semi trailer which has a triple axle in tandem at the rear. This calculator also assumes you are using a weight-distribution hitch when towing your RV, if you’re towing a travel trailer. At TruckScience, we’ve created an Axle Weight Calculator that brings all the truck specs and legislation together, so you can calculate weight distribution, dimensions, maximum payload and center of gravity, and comply with manufacturer and regulation limits. (Alternative method of computation: 33,600 lbs.) Gross Vehicle Weight.

Maximum Legal Weight Allowed Tandem Axle (Two Axle) 34,000 lbs. I've done some axle weight load distribution calculation before for some trucks with two axles. How much weight can a 2 axle truck carry 34,000 lbs. I'd like to ask you for some inputs on this problem I'm having. This function does not take into consideration the gross axle weight rating (GAWR) or the gross vehicle weight rating (GVWR) of the vehicle.
