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."
