The Utilisation score compares the Gross Weight to the Permissible Weight on each axle, axle group, and for the chassis as a whole. For example, if the Gross Weight on the front axle is currently 9,000 lb, but the Permissible weight on this axle is 10,000 lb, 90% of the maximum capacity of the axle is being utilised. This is expressed as a Utilisation score of 90%. (The Permissible weight is determined by the lesser of 1. the axle rating and 2. the legal limit for that axle.)

Yes, it is possible to mix measurement systems. Go to Settings > Measurement and select the configuration you need.

TruckScience does not flag issues with layout of components, for example, where components will not fit in the space available. In some cases, a user may become aware of potential spacing issues, having reviewed the drawing, but the layout is not verified by the program.

Because CA and WB are both ways of expressing chassis dimensions, and changing one automatically affects the other, you can choose which one is editable. Toggle ‘Specify Chassis Dimensions As’ under Settings > Preferences.

A snow plow may be added in TruckScience, either by uploading a drawing, choosing a standard snow plow from the TruckScience library, or by using a generic TruckScience template.

To add your products to the TruckScience library, you will need to gather the following information:

– A simple ‘general arrangement’ side-view drawing.

– Some high-level dimensions – This will include the outer length, height and width of the product, and may additionally include some equipment-specific dimensions, such as the hook offset and platform height, in the case of a hooklift.

– The total weight of the product, and the position of its centre of gravity.

You may upload your own drawings using the ‘DXF import’ feature, or you can share a drawing in PDF format to be uploaded by the TruckScience team.

TruckScience contains a library of simple high-level drawings of chassis, bodies, equipment and payload. These drawings are obtained from various sources, including images in PDF documents, CAD drawings, etc.

Should you choose to share CAD files with TruckScience, your files will be used to generate simple drawings, but your original CAD files not be uploaded to the platform, and may not be accessed by other users. TruckScience habitually signs NDAs to reassure manufacturers in this regard.

Furthermore, subscribers to the Enterprise edition may choose to limit access to product specs, by adding them to a private ‘Distributor Library’. In this case, only approved users will have access to the drawings.

Having chosen a chassis, the user can add bodies, equipment, trailers and payload from the TruckScience library, or import their own, from a DXF file.

Ambulance bodies can be imported to the TruckScience library, in the same way that dump bodies, service bodies, etc. are added. These can be added to a chassis to examine weight distribution, centre of gravity, turning radius, etc.

To add a product to the TruckScience library, you will need a drawing in DXF format, major dimensions (length, height, width, etc.), total weight and centre of gravity.

To upload a dump body, start the process of adding a dump body, then select ‘Import DXF’ to open your DXF file. The wizard will guide you through the remaining steps.

When you have uploaded your product, you may choose to save it for reuse in future, either by yourself, other users on your account, trusted distributors only, or by all users of TruckScience. Please reach out to the TruckScience team if you wish to promote the product to users outside of your organisation.

If a drawing is not available in DXF format, but you have access to a drawing in e.g. a PDF document, please <contact us> for assistance.

Bodies and equipment which have been shared with users outside of your organisation through your Distributor Library, can be removed from your Distributor library at any time. Furthermore, access to your Distributor library may be redacted at any time. Bodies and equipment that have been added to a calculation that was saved by a user will remain in that calculation.

The fifth wheel vertical load is calculated, and is used to calculate the weight that is distributed to the tractor from the trailer. To display the 5th wheel vertical load, that is the weight on the kingpin, add it to your ‘Favorite Measurements’ (Settings > Dashboard > Favorite Measurements)

The permits that are currently catered for are listed in the ‘Regulations Applied’ dropdown under Settings > Dashboard.

If there is a permit that you would like to have added to this list, please contact us.

TruckScience contains and library of road regulations, including for all US states and Canadian provinces. This includes regulations for Interstate and State roads in California.

TruckScience sources the relevant information about State and Interstate road and Bridge regulations from various official websites, includes NHTSA (National Highway Traffic Safety Administration), Department of Transportation, etc. When regulations are ambiguous, TruckScience engages with the relevant authorities to seek clarification.

TruckScience includes a library of DoT weight and dimensions regulations. This includes regulations for Canadian MOU (Memorandum of Understanding), and provincial regulations for Alberta (AB), Atlantic provinces, British Columbia (BC), Manitoba (MB) Class A1 and B1, and RTAC including Higher Weights, Ontario (ON) including SPIF, and Quebec (QC) including Thaw Period, Saskatchewan (SK) including Primary and Secondary, Higher Weights and Winter weights.

For now, we have included Northern Territory under the Australian National regulations.

If you are aware of weight allowances granted to heavy vehicles in Northern Territory over the national regulations, please contact us.

The program is backed by regulations for all US states and Canadian provinces, as well as regulations for other jurisdictions. Bridge limits may be affected by the addition of pusher and tag axles.

It is possible to add axles to your configuration and move them around on the chassis, and observe axle limits being updated on the fly. As axle limits are re-calculated, so too is maximum payload, etc.

Vehicles configured in the Loading module can be simulated travelling over a route of your choice in the Performance module. The fuel consumption values calculated in the Performance module are fed into the Costing module to calculate Total Cost of Ownership. TruckScience is used to evaluate one vehicle at a time, and this information can be fed into a wider fleet-level study.

The distance between axles (measured from the centre of the axles) can be modified, to examine the effect on axle weight distribution, and maximum achievable payload.

Auxiliary pusher or tag axles may be added to a chassis, and specified as Steering and/or Lifting. The Maximum Lifting Travel may also be specified. The axle can be raised or dropped, and can be examined under empty and full load conditions, to compare weight distribution and verify compliance with DoT regulations.
