We’re often asked if our Axle Weight Calculator is an alternative to TrailerWIN. Here we address some of the similarities and differences between the 2 programs, as we understand them.
How TruckScience and TrailerWIN are similar
As with TrailerWIN, one can use TruckScience Axle Weight Calculator to calculate truck axle weight distribution, bridge formula, optimal payload, multiple point loads, diminishing load curve, turning circle and cab tilt arc.
Axle weight distribution / Axle load calculator
In addition to limits imposed by manufacturer’s ratings, and in the interests of protecting roads and road users, most jurisdictions impose limits on individual truck axles (Gross Axle Weight Rating), as well as Gross Combined Weight Rating, Gross Vehicle Weight Rating, etc.
Use pre-loaded vehicle specifications, or create a vehicle from templates within the program, to calculate distribution of weight – including curb or kerb weight, weight of body & ancilliary equipment (crane, fridge, taillift, etc.) and payload – over the axles of the truck and/or trailers.
Designs are automatically checked against legislative limits which are pre-set in the program. The legislative checks that are carried out are concerned with areas including weight distribution, overhangs, corner distance and turning circle.
Bridge formula (or Federal Bridge Gross Weight Formula)
Bridge formula is necessary to prevent heavy vehicles from damaging roads and bridges. A truck with a shorter wheelbase can cause more wear and tear on bridges because its weight is concentrated in a smaller area and therefore can cause more stress on bridge members.
Bridge formula does not reduce axle load allowances, rather Gross Vehicle Weights (GVW), which can affect load distribution and actual axle weights. Designs are checked against Bridge Formula legislation where applicable.
Optimise the dimensions of the truck body or trailer and calculate the optimal maximum payload carryable.
Multiple point loads
Graphically plan a multiple point load, for example when carrying a palletised load or steel coils, etc. Move load items forward or backward to correct overloading of a particular axle.
Deloading Curve or Diminishing load curve
The 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.
Turning Circle / Turning Radius
The turning circle or turning radius of a truck denotes the smallest circular turn that the vehicle is capable of making. This calculated circle is compared to the largest turning circle allowable by the relevant jurisdiction’s legislation. Customers with space restrictions in their parking areas are also interested in these figures.
Cab tilt arc
Use this measurement to ensure that there is sufficient clearance between the cab and the fridge unit when the cab is tilted.
The following are the truck and trailer types which are supported by both programs:
- dual-axle / 4×2 / 4×4
- standard triple-axle / six-wheeler / 6×2 / 6×4 / 6×6
- standard four-axle / eight-wheeler / 8×4 twin steer
- eight-wheeler with triple bogie / 8×4 single steer
- five-axle (ten-wheeler) truck
TruckScience and TrailerWIN allow you to configure truck and trailer combinations with 1 or 2 trailers
- drawbar trailers with 2, 3, 4 (2+2 or 1+3) or 5 axles
- pup (single-axle or centre-axle) trailers, with single axle, dual-axle or triple-axle bogie
- semitrailers with 1 – 4 axles
- 1, 2 or 3 axle interlink trailer (for B-double combination)
Both programs include a database of vehicles & standard equipment, as well as legislations to be applied to the calculations.
How TruckScience Axle Weight Calculator and TrailerWIN are different
Our user feedback suggests that TruckScience Axle Weight Calculator is very usable by non-engineers, while TrailerWIN is more suitable for engineers.
TrailerWIN is a desktop application, whereas TruckScience Axle Weight Calculator is available online.
TrailerWIN provides comprehensive data updates on a regular basis, whereas TruckScience Axle Weight Calculator adds vehicle, trailer, body and equipment data on request, and they become available to the user immediately thereafter.
There is no upfront cost associated with TruckScience Axle Weight Calculator. The annual cost of TruckScience Axle Weight Calculator is €432.
TrailerWIN has some advanced features that are not available in TruckScience Axle Weight Calculator, such as Stability calculations and Load Curve.
– Stability Calculations
Stability calculations are provided by CraneWIN, an add-on to TrailerWIN, at additional cost. This program calculates the static stability of vehicles with extended vehicle cranes.
– Load Curve
TrailerWIN’s Load Curve calculates the maximum payload achievable with the COG (center of gravity) at various points along the deck.
– Turning Calculations
TrailerWIN caters for complicated turning calculations with an additional add-on, CornerWIN. This add-on is available at an additional cost.
Export File Types
TruckScience calculations can be shared as TruckScience (.tsc) files or exported to PDF for sharing with non-users of the program.
TrailerWIN calculations are additionally save-able in DXF format, for use in CAD programs such as AutoCAD, as well as .BMP bitmap graphics image file format and .TXT text files.
TrailerWIN is currently available in many European languages, while TruckScience Axle Weight Calculator is currently available in English only.
