PBS Assessments

One-Click PBS Assessments & Automatic Change Log

Simplify your workflow with Hevi Spec's intuitive 1-click PBS assessment feature. Save time and reduce errors with our automated process, delivering quick and reliable results.

Our new change log automatically saves and tracks design changes, so you don't have to. Just make a change, assess and then view and compare results

Build Any Combination Imaginable

You're only limited by your imagination. Build limitless trailing units and axles. Steerable axles, and assess any combination with wide single tyres, we've got it all covered, uneven load distributions, spread axle groups

Intuitive Interface

Intuitive Interface & Presentation Drawings

Get designing with our intuitive interface and create beautiful layout drawings. Drag your axles and equipment into position or input dimensions directly. We support metric and imperial units and have an in-line calculator to speed up productivity.

Morphable Cabs, 3D Asset Database & Digital Twins

Use our generic 3D models which can morph to your specification or select from our database of popular 3D Truck Cabs, Trailers, Dollies, Bodies, Axles, Tyres, Suspensions, Fuel Tanks, Bull bars. Upload your own CAD data, point clouds or scans for accurate digital twin to compare your design with reality.

Testimonials

"Tiger Spider’s Spider Path tool has recently been rolled out across The Department of Transport’s Heavy Vehicle team. Where sufficient google imagery exists, the tool provides a user-friendly, intuitive approach to what was previously a complex process. The team have enjoyed using the tool and the benefits it provides through its bespoke vehicle creation functionality. Marcus and the team have been open to improvement suggestions, and have continued to roll out new features since its launch."

"Tiger Spider’s Hevi Spec online software is an innovative, intuitive and easy to use tool. It’s an absolute must-have for any serious player in the PBS space."

"Tiger Spider’s Hevi Spec Advanced helps Hendrickson design and develop better performing suspensions and to optimise suspension solutions to best achieve customer requirements. Hevi Spec online is easy to use and allows us to quickly assess suspensions performance in any truck and trailer combination, and with UM Multi-Body Dynamics/FEM we’ve taken our simulation capability to the next level. We can now combine CAD, FEA, MBD and FEM to keep us further ahead in developing best in class axles and suspensions for the demanding Australian market."
