TESTED IN AUSTRALIA
MAX front protection bull bars were strictly tested by Australian Safety Engineering (ASE) who perform compliance and conformance testing to established Standards.
With over 50 years of accumulated experience in automotive design, development and testing, ASE was awarded the prestigious USA Engineering Excellence Award in 1996 for outstanding contribution to automotive safety.
MAX BULL BAR TESTING
Bull bars are fitted to the front of the vehicle to protect it and it’s passengers from damage in a collision. ASE’s pendulum test facility, which was designed and built to Society of Automotive Engineers (SAE) standards is utilised in ADR69 testing and allows design engineers to carry out multiple tests to prove the validity of their design.
We started by sending one bull bar of each model to South Australia for testing.
The bars were impact tested for airbag compatibility and ADR compliance using the following calibrated equipment:
ASE data acquisition system.
Bruel & Kjear 4370 Accelerometer.
Bruel & Kjear 2635 Charge Amplifier.
Specially constructed pendulum impact test apparatus.
This also included static testing on the recovery points, which are rated at 4000kg. The bar was mounted to a simulated vehicle chassis and the maximum instantaneous force applied in longitudinal and 45 degree angles. The results concluded the rating on each recovery point to be true.
Please note, it is strongly recommended for safety, when using recovery points for the retrieval of your vehicle or using your vehicle to retrieve another, that an equaliser strap is used from both recovery points.
MAX REAR BAR TESTING
We then sent MAX rear bars from each model for testing by ASE.
The test procedure included mounting the rear bar to a replica vehicle body which was firmly restrained in order to eliminate movement of the frame which would affect test results.
The following loads were applied via the tow ball of the rear bar:
Forward longitudinal forces-minimum load 1.5 times the aggregate trailer mass for which the towbar is rated.
Rearward longitudinal forces-minimum load 1.5 times the aggregate trailer mass for which the towbar is rated.
Transverse force-minimum force 0.5 times the aggregate trailer mass for which the towbar is rated. Tests are to be carried out in both left-hand and right-hand directions.
Downward vertical force-minimum load the aggregate trailer mass for which the towbar is rated.
Upward vertical force-minimum load the aggregate trailer mass for which the towbar is rated.
The equipment used included:
2.1 ASE towbar test facility.
2.2 A&D load cell 5 tonne capacity. Accuracy +/-1kg.
2.3 Dial gauge Mitutoyo. Accuracy +/-0.01mm.
All instruments were calibrated.
The testing showed that the towbar tested in accordance to ADR62/02 compliance and tested according to the rated towing capability of each vehicle.
