Hooklifts and 11 More States!

Hooklifts and 11 More States! 1024 614 TruckScience

We’ve released another exciting update to the TruckScience Axle Weight Calculator this morning.

Hooklifts

The TruckScience Axle Weight Calculator now has full support for Hooklifts.

The app will calculate Body Overhang, After Frame (AF) and Rear Bumper Protrusion dimensions based on the hooklift Length, A-Frame Length, Hook Offset, Position of the Center of the Roller, Platform Height, Hooklift Height and Width.

As with other equipment items and bodies, you can import your own hooklift drawings from dxf files, use a generic TruckScience template, or add a standard hooklift from your own library or the TruckScience Public Library.

And of course you can manipulate the payload center of gravity to reflect the way in which payload may move towards the rear when the body is loaded.

More State Regulations!

The TruckScience Axle Weight Calculator validates your truck design against regulations for up to 5 states at once.

We’ve added truck size and weight regulations for Alabama, Connecticut, Kansas, Massachusetts, Missouri, Montana, North Carolina, Oklahoma, South Carolina, Tennessee and Wyoming this month. This brings the total number of states covered now to 34!

Detailed Dimensions

Many users of the Axle Weight Calculator have expressed a need to see detailed dimensions for equipment items on the drawing.

We’ve added the ability to pin detailed dimensions for any item of equipment. Dimensions may include length, height, distance from the back of the cab, hook offset, center of roller to center of the rear axle (for tippers, hooklift bodies, compactors, etc.), center of roller to end of bumper, end of hooklift to end of the chassis, and more.

Use the drawing pin symbol on the Equipment list to pin that item’s detailed dimensions to the drawing. To avoid cluttering the drawing, detailed dimensions for one item of equipment are shown at any one time.

More Dimensions

We now show more dimensions on the drawing by default. In the case of a Chassis Cab (Rigid or Straight Truck), these include the After Frame (AF), Rear Bumper Protrusion and Body Overhang.

The After Frame dimension is measured from the center of the driven axles to the end of the chassis. The Rear Bumper Protrusion is measured from the end of the chassis to the end of the bumper. And the Body Overhang is measured from the end of the chassis or end of the bumper, whichever is greater, to the end of the body. The Body Overhang is validated against the permissible maximum for body overhang, where applicable.

In the case of a Semi Truck (Tractor), we show the Cab to Axle (CA) or Cab to Trunnion (CT) dimension. This is measured from the center of the front axle to the center of the rear axle or axles.

High Productivity Motor Vehicles(HPMV) in New Zealand

In New Zealand, High Productivity Motor Vehicles (HPMV) are trucks that are able to operate above the 44-tonne weight limit, under permit. Under regular NZ Land Transport Rule regulations, the maximum permissible Gross Combination Mass (GCM) is 44,000kg. Selecting Application = HPMV Permit increases the GCM, to 60,000kg, as well as the axle ratings.

Note that for these longer vehicles, or operation at higher mass on state highways, you will need to complete a High Productivity Motor Vehicles (HPMV) permit application form and send it to a Transport Agency office.

This image shows a 23-metre 9-axle B-Train in the TruckScience Axle Weight Calculator. The HPMV permit also applies to a rigid truck with dog or drawbar trailer

Big Truck Guide

We partnered with Big Truck Guide to add these state-level federal regulations. With a deep understanding of North American size and weight regulations, Big Truck Guide provides consulting services and publishes training materials and reference documents, all around the important topic of truck weight and dimensions compliance.
