Load regulators

Load regulators are used to automatically regulate the braking force depending on the load (weight) of the vehicle. Automatic load regulators (ALR) are either mechanical or pneumatic. Mechanical ALRs are used on vehicles with mechanical suspension (leaf springs), where the pressure in the brake cylinders is regulated depending on the suspension (angle of rotation of the ALR arm). Pneumatic ALRs are used in pneumatically sprung vehicles (air bellows), where the pressure in the suspension bellows changes depending on the vehicle's load, which serves as a control pressure for the correct regulation of the pressure in the brake cylinders.

At Penax, we offer load controllers from leading manufacturers Wabco, Knorr-Bremse and Haldex.
