GKN Stromag Brakes
GKN Stromag hydraulically, pneumatically, and electrically actuated brakes are highly developed and reliable components for modern and energy efficient drives. They ensure driving and hoisting safety, are protected against the most adverse environmental effects in their respective applications, are provided with precisely tuned safety functions, and are characterised by low noise levels. In travelling drives they keep construction machinery safely in place, and they retain rotary drives at the required position. Winches on cranes and ships are braked and retained in position even under the most difficult conditions.

GKN Stromag Crane Brakes
Electromagnetic Brake Caliper
- High degree of protection (IP 54)
- Low maintenance
- Simple and fast replacement of high wear resistant brake linings
- Unvaryingly large release path
- Large wear reserves
- High thermal capacity and good heat dissipation
- Mechanical release through central release screw
Function and application
Disc brakes functioning as operating or emergency stop brakes are used to brake safely loads on hoists, trolleys, and winches. Both the electromagnetic and hydraulic versions present convincing advantages in the form of large and unvarying braking torques, little maintenance and storage work, low space requirements, and very short, stable engaging times.
In the event of a break in the kinematic chain (for molten or radioactive material), emergency stop brakes must engage and execute emergency lowering when faults occur in other braking systems and/or the lowering speed exceeds the rated value by greater than 10%.
Hydraulic Brake Caliper
- Active hydraulic brake for azimuth adjustments
- Braking force FB = 0-210 kN
- Setting the pressure adjusts the torque
(full or controlled braking torque)
- Surface protection class C4-L standard ISO 12944-2 (excluding functional areas)
- Option: surface protection C4-H or C5M-H
- Standard ISO 12944-2
- Option: VCI packaging
- Screws and discs are not included in delivery.
Function and application
The brake calliper CB90A is characterised by its high braking effect and ease of maintenance. These advantages are the result of the following innovations (patent application submitted). The central web causes the braking force to be distributed over a total of four webs, thereby reducing considerably the load in the highly stressed area. As a consequence, higher braking forces can be generated.
Simple wear status query and easy replacement of the friction linings
