Cam brakes

Robust cam brakes offer the advantage that they are operated not only mechanically by use of external cylinders, but also hydraulically or pneumatically. The combination of a service and a parking brake is thus made possible.

Cam brakes are mainly used as parking brakes. But they may also be found in trailers with pneumatic brake systems, where they act as a combined service and parking brake in an S-cam version.

Available sizes: Ø 115mm – Ø 500mm
Breaking torques: up to 35,000 Nm

Hydraulic fixed-calliper disc brakes

These brakes are characterised by a fixed connection with the wheel suspension. The braking force on the brake disc is produced by two pistons mounted in opposition.

The advantage: in contrast to floating or sliding callipers, fixed-calliper disc brakes have no sliding elements and can be used off-road or in dirty environments.

Available sizes: 2, 4 or 6 pistons with diameter of 40 – 92 mm
Braking torques: up to 120,000 Nm

Hydraulic sliding calliper disc brakes

The application of the operating force in hydraulic sliding calliper disc brakes takes place via one or more pistons. The operating force of the opposite side is produced by the reaction force of the sliding calliper, which is supported by the brake pads on the disc.

This design makes it possible for the brakes to be mounted as usual in the wheel rim. Generally, this brake design is suitable for on-road applications where restricted installation space is the case. Typical applications are for municipal vehicles, airport equipment and trailers etc.

Available sizes: 1 or 2 pistons with diameter of 40 – 72 mm
Braking torques: up to 10,000 Nm

Mechanical sliding calliper disc brakes

These brakes employ a brake lever that is controlled by compressed air, a hydraulic or spring pack cylinder, or via a control cable or linkage and a hand-brake lever. Mechanical sliding callipers are used as service and auxiliary brakes.

Available sizes: MGS 22, MGS 33, MGS 40, MGS 45 and MZB 40
Braking torques: up to 6000 Nm

Pneumatic disc brakes

The operation of a pneumatic disc brake takes place on one side only via an external diaphragm cylinder. The operating force of the opposite side is produced via the reaction force of the sliding calliper. The advantages over conventional systems are compact design, ease of service, and stable braking performance.

Applications for pneumatic disc brakes are found in heavy commercial on-road vehicles such as lorries, busses, mobile cranes as well as in trailers.

Available sizes: PGS 15 and PGS 22
Braking torques: up to 25,000 Nm

Hydromechanical sliding calliper brakes

These brakes offer not only a service brake function but also an integrated parking brake function. The application of operating forces is from one side only, either hydraulically via the service brake piston or mechanically via the brake levers. The operating force on the other side is produced via the reaction force of the sliding calliper itself.
One important advantage of our bakes is the reinforced components of the parking brake unit, which allow the vehicle to be stopped on steep gradients. The brakes are mainly used in construction machinery and special vehicles.

Available sizes: piston diameter 52 – 56 mm
Braking torques: up to 2600 Nm
