Extended standard These application modules provide you with further function solutions beyond those for standard applications. n Simultaneous operation of hoist drives: This function enables two drives to be synchronised without a mechanical connection. The positions of the rotors are continuously monitored and matched. The drives of two hoists can be synchronised for handling long material, for example. The hoists can be used separately by switching the function off at any time. n Load distribution: This ensures equal distribution of loads to two mechanically connected Motors. The function can also be used for redundant applications.

Customer-specific applications In addition, we offer further application solutions that are specially designed to meet your needs. Application modules are also available with power recovery units. They enable the high energy generated when hoist units brake to be fed back into the line power supply (regenerative braking). Benefit from our many years of experience and utilise our consultation service.

Decisive benefits of application modules n Special requirements of travel and hoist drives are met n Reduced planning requirement for the installation n Greater certainty for cost calculation n Wide range of applications n Outstanding solutions based on the Demag standard n Faster and more efficient connection of the complete solution (only power supply, motor and control lines)
