BRAKES

Find the perfect brake for your demand:

Calzoni Hydraulics parking brakes are designed to guarantee to hold a hydraulic system under an external torque.

Calzoni Hydraulics brake series is a spring applied – hydraulic released multi-disc wet parking brake, engineered for applications where it is absolutely necessary to hold the system under an external torque.
Any function, which reduces the hydraulic system pressure below the release pressure of the brake, will cause the brake to be activated.

Product Overview

Calzoni Hydraulics brakes are designed to guarantee to hold a hydraulic system under an external torque.

Calzoni Hydraulics “B” brake series is a spring applied – hydraulic released multi-disc wet brake, engineered for applications where it is absolutely necessary to hold the system under an external torque.
Any function, which reduces the hydraulic system pressure below the release pressure of the brake, will cause the brake to be activated.

APPLICATION

Working Principle

The brake is operated by a single-acting piston (1) with opposing springs (2) between the piston and the front cover (3). During load braking and stop, the springs press against the piston blocking the discs.
Hydraulic pressure is required to release or “hold off” the brake and during normal operation the brake is pressurized in the released position: any function which reduces the hydraulic system below the release pressure of the brake will cause the brake to be applied.
