Trucker's Slide Calc
A mobile application to help semi truckers quickly slide their single, tandem, and tridem axles. It also makes it easy to calculate individual axle weights with weighbridge/whole-truck scales. Click one of the following subjects to learn more.
Use the app to quickly see axle/gross weights and which ones, if any, are over regulation.
How to use a platform scale by weighing as you pull onto the scale.
-
Pull onto the scale far enough that only the steer axle is being weighed.
-
Enter the scale's weight into the "Steer" box in the app.
-
Pull onto the scale far enough so the steer and drive axles are being weighed.
-
Enter the scale's weight into the "Steer + Drive" box in the app.
-
Pull onto the scale all the way so truck gross is being weighed.
-
Enter the scale's weight into the "Gross" box in the app.
-
All three axle weights are now calculated and shown in their boxes.
-
The weights under/over regulation are also displayed with the image. Any weight over the limit will be red.
Note: The app also allows you to calculate axle-weights when pulling off a scale. To do so, start by measuring and entering your truck's "Gross" weight, then measure and enter the "Drive+Trailer" weight, last weight and enter the "Trailer" weight.
How to use an axle scale.
-
Weigh the steer axle and enter it into the "Steer" box.
-
Weight the Drive axle set and enter it into the "Drive" box.
-
Weight the Trailer axle set and enter it into the "Trailer" box.
-
Truck gross will now be shown in the "Gross" box.
-
The weights under/over regulation are also displayed with the image. Any weights over the limit will be red.
-
Enter your load's weight as explained in "Axle-Weight Calculator" above.
-
(optional)Starting from the front of the trailer, count the number of holes until the first slide pin. Enter this number in the "Trailer on hole" box.
-
Check the distance between the trailer holes and enter it into the "Holes every" section. Holes are measured from center to center.
-
Tell the app which type of weight you entered in step 1(lbs/kgs) in the "Show weight as" dropdown. Changing this box with weights already entered will ask if you need to convert them to the new unit.
-
Select which type of balance-calculation you want the app to perform.
Note: The default option balances the drives and trailers as evenly as possible. This is known to give better fuel-efficiency and smoother rides.
Plus-users can change the option to maximize trailer weight instead. Maximizing trailer weight results in the smallest possible kingpin-to-rear-axle distance (for "bridge-laws"), the smallest possible turning radius, and allows you to add the most amount of tractor-fuel possible on heavy loads. -
Click the next arrow. The app will show a suggestion telling you how far, and which direction, to slide.
Convert weight from lbs to kilograms or from kilograms to lbs.
-
If required, clear all old-load data by pressing the eraser button at the bottom of the screen.
-
Select what type of weight you are going to enter in the "Show weight as" box (pounds/kilograms).
-
Enter your truck's weights.
-
Change the "Show weight as" box from the input weight type to the desired weight type.
-
A prompt will appear asking what type of weight the already-entered values are in. Select the type of weight you entered.
-
The app will automatically convert your truck weights to the new unit.
