The revised standards on braking under “Mother Regulation”
The abolsamia’s last issue (number 98) includes an article about the revised braking requirements for agricultural machinery coming into force in 2016. For those not able to read the full article in Portuguese, we publish an interview with Mr. Ivo Hostens, Technical Director of CEMA – European Agricultural Machinery, which summarizes what’s important to retain about this subject.
Abolsamia: The revised European legislation concerning braking performance is dealing, above all, with homologation of new agricultural equipments made by manufactures. But, for the owners of used equipments there is also a need, in some specific situations, of adequate existing vehicles to comply with new rules?
Ivo Hostens: The new Braking Regulation prescribes the road safety performance of new agricultural vehicles including tractors (category T), agricultural trailers (category R) and agricultural interchangeable towed equipment (category S). Used equipment is not under the scope of the regulation which means that the new requirements are not applicable.
Abolsamia: The inclusion of an emergency brake system is required for new tractors. How does it work, what’s the reason behind the inclusion of this system, and in which real life events can we predict it will be used?
Ivo Hostens: Several braking systems (service, secondary, parking and automatic braking system)are included de facto in new tractors today providing a high braking performance for the tractor or for the combination of tractor and towed equipment when driving on the road or pathway.In case of failure of the connecting braking lines the automatic braking system will be activated.Thanks to this technology, the tractor-trailer combination will reduce its speed slowly allowing the operator to guide the vehicle to the side of the road / pathway resulting in a safe stop.
Abolsamia: This revised legislation seems to open new possibilities for inertia braking in trailers. How can it be developed?
Ivo Hostens: This technology has been already provided by manufacturers over the last years.Inertia brakescan be installed on all towed vehicles (trailers, spreaders, balers)with speed limit up to 40 km/h and a sum of the permissible axle load of less than 8 ton. These kind of brakes can also be installed on smallertowed vehicles with a mass below 3500 kgthat can drive faster than 40km/h.
Abolsamia: Such as trailers, there are other trailed implements in the scope of the new regulation (bailers, spreaders, etc)? What’s planned for this kind of implements?
Ivo Hostens: Indeed, other trailed implements e.g. balers, sprayers, spreaders are in the scope of the new regulation. It is important to mention that as of 2016 EU type approval can be requested for these kind of vehicles facilitating their placement on the market in every EU-28 country without any additional testing and this will also apply for braking systems.Yet, national approvals remainpossible for small volumes or regional placement of towed equipment.
According to the new Regulation and as far as it concerns brakes installation: towed equipment (except trailers) with a mass <3500 kg up to 40 km/h will not need brakes while for trailers, brakes are needed as of 1500 kg mass. Those trailed equipment, whose ratio between laden and unladen mass is bigger than 3, will be considered as trailers and therefore will have to follow the requirements of the new braking regulation.
Abolsamia: Taking in to account the client’s point of view, in terms of braking what’s more important to consider and keep in mind concerning this new regulation?
Ivo Hostens: Modern high-end tractors and trailers are already equipped with the state of the art braking systems to ensure a higher road safety performance. The Regulation includes new specific rules on the compatibility between tractor and towed vehicle to make sure braking forces are well balanced, allowing an optimized braking performance between vehicles (e.g. tractor-trailer) and therefore ensure a high stability and steerability.
