DUAL CIRCUIT BRAKES – RELIABLE RETROFITTING
DUAL CIRCUIT BRAKES – RELIABLE RETROFITTING
Safety through Redundancy
Retrofitting from single-circuit to dual-circuit brakes decisively improves the safety of an elevator system: Two independent brake circuits significantly reduce the risk of complete failure. If one brake circuit fails, the second ensures controlled deceleration to a standstill.
FUKA has been a reliable partner for dual-circuit brake conversion kits for many years – perfectly fitted for almost all known manufacturers and gears. We also develop solutions for makes unknown to us at short notice.
Custom-fit solutions for existing systems
Our conversion kits are specially designed for the modernization of existing elevator systems:
- Compatible with a wide range of winches/drives (including older series)
- Project-related design for your specific system
- Fast retrofitting without unnecessary downtime
- Clearly defined scope of delivery – from mechanical connection to brake release
The systems are designed so that – depending on the variant – existing components (e.g. brake levers or brake shoes) can continue to be used or completely replaced. This reduces effort and costs in retrofitting.
Legal / testing context
During the inspection of elevator systems, the functionality of the brakes including redundant brake functions is checked; dual-circuit brakes are explicitly mentioned as an example of such redundancies. (TÜV Association)
A professionally designed dual-circuit brake thus supports a safe and testable modernization of existing systems.
Holistic Retrofit Approach
On request, we supply not only the conversion kit but a complete retrofit concept:
This gives you a consistent solution from a single source – technically clean and economically plannable.
Dual Plunger Brakes / USA-Code-Retrofits (ASME A17.1 / CSA B44)
For the US and Canadian market, we offer Dual Plunger Retrofit solutions through our subsidiary
FUKA Elevator Solutions USA
. Information and contact can be found at:
In parts of the USA, new and retroactive code requirements mean that many existing systems with single-plunger brakes must be converted to dual plunger by 01/01/2027.
Together with our partner Hyperion Solutions, we offer the Titan Dual Plunger Retrofit Brake Kit – a pre-engineered, code-compliant modernization solution for older traction machines (geared & gearless) that can be retrofitted without removing the machine.
The Titan Kit was awarded "Product of the Year 2025" (Safety Products) by ELEVATOR WORLD.
