A solution for extremely long decelerations

The object to be fitted with the brake system was a four-wheeled truck for mining operations. The truck transports various robot controlled machinery with large overall weights and the brakes are sometimes exposed to massive stress, because the truck must be able to brake gently on all four wheels on long stretches, sometimes as long as up to 10 kilometres.

The system we have produced consists of newly developed, heat-resistant disc brakes as service brakes on all four wheels – with heat shield equipped brake pads that provide better prerequisites to withstand the extreme heat generated at times. The disc brakes are also fitted with parts that make them more heat-resistant and better equipped for a tough environment.

The system solution also includes emergency and parking brakes on all wheels. These are applied by spring cylinders that actuate if the release pressure is lost during valve actuation or an accident. A very safe solution, which for several years we have been delivering to our customer's production plant in Finland.
