Load Xpert Flatbed

  • We’re often asked how our Axle Weight Calculator compares to Load Xpert.

Features for Paper Rolls

TruckScience’s Axle Weight Calculator and Load Xpert’s Axle Load Calculation programs are both used to calculate axle loads, maximum payload and U.S.

bridge formula. While there are a lot of similarities between the programs, here we address some of the differences, as we understand them. In addition to axle weight distribution and U.S. Bridge Formula calculations, TruckScience calculates the turning circle or turning radius of a truck.


  • The turning circle denotes the smallest circular turn that the vehicle is capable of making.
  • This calculated circle is compared to the largest turning circle allowable by your jurisdiction’s legislation.
  • In addition to the many features available in Load Xpert, TruckScience calculates turning circle or turning radius.
  • The following are the axle layouts which are supported by both programs:.
  • 2-axle / 4×2 / 4×4. 3-axle / six-wheeler / 6×2 / 6×4 / 6×6.
  • 4-axle / eight-wheeler / 8×4 tandem or twin steer. 4-axle / eight-wheeler with triple bogie / 8×4 single steer.



  • Load Xpert additionally supports the following axle layouts, which are currently catered for in TruckScience by adding standard vehicles, but will in future be catered for by the lift axle feature.
  • 4-axle: 1 + 1xLift + 2. 5-axle: 1 + 2xLift + 2.
  • 5-axle: 1 + 1xPusherLift + 2 + 1xTagLift. Some of the axle layouts available for selection in TruckScience.

Load Xpert - Load Planning Product Features

  • Lift axles are non-powered axles, and are installed ahead of or behind the driving axles on a straight truck or tractor, or a trailer’s tandem.
  • If a lift axle is ahead of the driven axle, it’s called a pusher. If it’s behind, it’s a tag.
  • Both TruckScience and LoadXpert support adding axles to a truck. The Deloading Curve or Diminishing load curve demonstrates how the weight distribution over the axles changes as a load is offloaded from the rear of the truck or trailer.
  • In some cases, a truck that started its journey in a legal state becomes overloaded on the front axle if part of the load is offloaded from the rear of the truck.

  • About Load Xpert - Load Planning

    Diminishing Load Curve: In this case, the front axle(s) become overloaded as the truck is unloaded from the rear.

  • Audience

    Both programs calculate front to back center of gravity (CG-X) of the completed vehicle.

  • 03

    In addition, Load Xpert calculates vertical (CG-Y) and lateral (CG-Z) center of gravity (CG). Due to the requirement to specify the combined vertical CG of added components on the IVD (Incomplete Vehicle Document), TruckScience plans to add combined Vertical Center of Gravity calculations in May 2016.

  • 04

    TruckScience calculations can be shared as TruckScience (.tsc) files or exported to PDF for sharing with non-users of the program.

  • 07

    Existing CAD drawings can be imported into Load Xpert using LX-CAD, Load Xpert’s drawing package.

  • Load Planning Software

    At present, TruckScience does not support DXF import or export, but this feature is also on our Product Roadmap for future release.

  • Load Xpert - Load Planning Frequently Asked Questions

    TruckScience compares the current calculation to relevant legislative limits which are pre-set in the program.

  • 05

    The legislative checks that are carried out are concerned with areas including weight distribution, overhangs, corner distance, turning circle and bridge formula.

  • 02

    This is in addition to the checks against manufacturer ratings which are carried out by Load Xpert.


  • Choose your legislation in TruckScience to apply axle loading limits and maximum dimensions.
  • TruckScience Axle Weight Calculator currently supports saving of vehicles, with or without body and accessories, and these saved calculations can be shared among users.
  • LoadXpert allows the user to save vehicles, bodies and accessories separately, so that bodies and accessories can be reused across various vehicles.

  • A great number of optional dimensions can be defined in TruckScience, when it comes to – among others – cab dimensions, width dimensions (Overall, Cab, Rear, Track and Chassis), turning radius, steering angle, etc.
  • Of course, many of these dimensions are used by TruckScience in calculating the turning circle of the completed vehicle.
  • TruckScience currently imposes a limit of 10 accessories, whereas Load Xpert allows unlimited accessories to be added.


  • Load Xpert provides a detailed Accessory List, which is available as a printed report. In order to see this detail in TruckScience, a user currently needs to be logged in to the program.
