New ViaFriction General presentation H. Farstad,

● Features of the new ViaFriction unit – Twice as much braking power as previous model – Vertical load > 100 Kg (Previously 50Kg) – Less variation in vertical load than previous model – Can measure high friction surface in 20 Km/h – Measurement unit increased by 20Kg ● Still free floating vertical load, rugged design and easy & accurate distance calibration due to ONE wheel. New ViaFriction

Easy to use New ViaFriction ● In Norway, the driver operates the system ● Easy to use Windows user interface ● User interface contains the information you need while measuring ● Extensive check of system while measuring ● Extensive and easy to use self-test

Easy to maintain New ViaFriction ● Easy to maintain the equipment, few parts ● Self-test pinpoints the faulty part ● Easy to fix mechanical and electrical problems ● Remote control and service from ViaTech via PC

Fixed slip measurement New ViaFriction ● Can adjust slip percentage from 1% to 75% in the software within 30 sec. ● Normal slip percentage 15-20% ● Measures 30Km on 1000 litre tank ● Excellent repeatability ● Keeps calibration for years

Variable slip measurement New ViaFriction ● Gives the whole curve ● Gives much more information than fixed slip ● F30, F60, Sp

Nantes April 2015 Testing ViaFriction

● 10 longitudinal friction devices participated from all over Europe (2 commercial available for road survey: ViaFriction and Griptester) ● 11 different surfaces on test track – Each track measured in 3 speeds, and 80 km/h – Each track measured 5 times – Friction level from 0.1 to 1.0 ● 7 different surfaces on normal road outside test track – Each surface measured 3 times – Road measurement speed 60 km/h Testing ViaFriction Nantes April 2015

● Project objectives – Create a standard for measurements ● Data processing – Average and standard deviation for each surface – Data sent Rosanne project by end of May – Rosanne Report much later Testing ViaFriction Nantes April 2015

5 measurements, unfiltered data Nantes April 2015 Testing ViaFriction ViaFriction: Repeatability 5 measurements give same result !

ViaFriction-sum up On the market since 2006, more than 70 sold Easy operation by use of a touch screen laptop Operated in normal traffic speed with controlled water flow 1000 liter water tank gives approx. 30 KM of survey Standard trailer coupling with AL-KO stabiliser Result may be reported as text files. May be imported to Excel Temperature-, humidity, MPD and GPS sensors as option ViaPhoto system and web as option Support different testing modes: Fixed slip mode (with adjustable % in the software) Detection mode for reducing wear of tire & equipment Variable slip mode Easy to calibrate, just adjustment in the software Robust device with low maintenance costs Remote diagnostics for online support Trailer solution(EU approved) with superb suspention or on Truck/Van Results provided instantly (realtime with WEB) Some of the friction devices measure as much as km per year on uneven roads

ViaFriction-design water system Flow is controlled according to speed Protection system prevent dry run The water tank of liter can be filled automatically from water stored in the towing vehicle 1000 liter gives approx. 30 km of survey

SPIRAX: ● TREDAL has constructed its own suspension system. It was developed over several years and called SPIRAX ● The system consists of: ● 1 Coil springs on swing arm ● 2 Hydraulic double acting shock absorber ● 3 Rubber Stopper to prevent breakage / damage by overload or reckless driving. ● SPIRAX is based on the same principle as most cars have today, i.e. that a TREDAL trailer has virtually the same handling characteristics as your car. It provides comfortable and secure transport also on bad roads. ● ViaTech has further improved stability ViaFriction-design trailer EU-approved
