Expansion of the Demag DHR rope hoist range
U
nveiled at LogiMAT 2024, Demag is extending its DHR rope hoist portfolio with two new designs: the F-DHR foot-
mounted hoist and the EZ-DHR double-rail crab, joining the already introduced EK-DHR short crab version designed for crane applications. The DHR series stands out for its compact design, high performance and versatility, targeting the broad global market for standard crane technology applications. These rope hoists were developed last year for series production.
With the two new additions to the series, the F-DHR foot-mounted hoist and EZ-DHR double-rail crab, crane and system builders can choose from the compact basic hoist for stationary applications, which can be mounted on the wall or the floor. A reeving device is also available.
Developed for a wide range of applications in all crane technology, the complete DHR series is characterised by its compact size and lightweight construction. Other features include its high performance and load capacity with minimum service requirements. The motor and gearbox are also easy to access, and no lubrication is needed for the rope drum bearing. Depending on the application, three motor solutions are available for the DHR hoist

drives. Options range from two-stage hoist motors with a 6:1 ratio to inverter-controlled motors featuring the Demag ProHub function, which enables load-dependent speeds up to three times faster. The EK-DHR monorail version of the cross-travel drive comes with the Demag DualDrive as standard, a powerful solution where a single belt drives two wheels simultaneously. For more challenging conditions, a second motor can also be used (DHR 10 ). An innovative alternative to steel rope, users can reduce weight and simplify rope replacement for service personnel with a high-strength synthetic rope used in the DHR rope hoist. The Dyneema ropes are 85% lighter, eliminate wear on the rope drum or guide rollers, and do not require lubrication. As the drum geometry is identical, users can also easily switch between synthetic and steel rope after installation. The innovative control and safety
technology of the DHR series sets it apart from its predecessor, the DVR series, and many other wire rope hoist series on the market. Since the crane components communicate via an optional CAN bus, numerous safety-relevant parameters can be monitored automatically. Additionally, users can choose from a range
of smart features to adapt the rope hoist to specific applications for maximum impact, such as load sway damping, bypass control and hook centering. These features make the DHR ideal for demanding lifting and handling tasks. It is not only the rope hoist electronics that satisfy the highest demands – the web- based remote monitoring tool StatusControl 2.0 enables users to monitor numerous functions remotely. Through Demag Equipment App (DEA), users and service personnel can track real time rope hoist or crane data on their terminal device. Trained users can also adjust the DHR’s parameters. Being connected by wireless means that the DHR supports software updates over the air for existing cranes. The DHR has also been further upgraded in terms of safety: features such as the ergonomically shaped hook block with guide handle and intervention guard set new standards for ergonomic and safe crane operation. With the expansion of the series to LogiMAT 2025, four DHR rope hoist types in different load-bearing classes up to 20t are now available. And the development doesn’t stop here – additional models are already in the pipeline.
