Service brakes overheating is a major risk as it can lead to complete loss of the brake function and dramatic accidents. In order to mitigate this risk, Sandvik has developed an Electrical Brake Retarder for selected trucks models.
The Electric Brake Retarder supports the truck service brakes system by acting as a supplementary brake system. It dissipate the braking energy by generating eddy currents. The eddy currents produce a gradual rise in rotor temperature and the heat is then released into the atmosphere through ventilation systems. With this “induction braking systems”, it is thus possible to effectively slow down the transmission rotating shaft without friction and therefore without wear.
This technology guarantees unequalled instantaneous availability and full braking power provided by the retarder, regardless of the vehicle’s speed and it remains effective even after the engine stops, or when the gearbox is in neutral. Risks associated with service braking system overheating are therefore avoided and the system remains fully operational in case of emergency.
Trucks equipped with an Electrical Brake Retarder can multiply the lifespan of their service braking system up to ten times: maintenance costs are therefore greatly reduced and operational availability is increased.
The ease of use, flexibility and progressive character of Electrical Brake Retarder guarantees exceptional comfort for the Truck operator. Activated and easy to control with a switch located on the dashboard: once the function is turned on, it works automatically.
Electric Brake Retarder can be used with an empty or fully loaded box. Recommended for ramp haulage applications (i.e. backfilling).
