Hoist Unit Relaunch

Demag is expanding its DH hoist portfolio with a relaunch. New features include the standard size 400, the standardized option of infinitely variable positioning and a significantly expanded range of accessories, which have been combined into equipment packages.

"The DH series is a robust hoist series in the Demag range that goes far beyond classic crane technology and can be used wherever reliable load handling is required, even under extreme conditions," said a company spokesperson. "The hoist units feature a torsionally rigid frame, long hook paths (up to over 100 m) and versatile assembly options. Examples include applications in electroplating plants and infrastructure projects, as well as for horizontal movements."

A new addition to the standard DH range is the 400 size for load capacities of 1.1 tons or more. Like the other three sizes (600 to 2,000), it is available in various basic designs: as a compact foot-mounted hoist, as a standard-headroom monorail hoist (for monorail suspension and other applications), and also in curved design, as a short trolley with optimized hook path and as a double-rail crab.

There are also program extensions for the drives. The use of high-quality conical-rotor motors, 100% developed for demanding use in hoists and made in Germany by Demag at the Uslar plant, remains unchanged. They are available in different versions: as pole-changing motors with creep lifting (1:6 and 1:10) and as infinitely variable drives. New in the standard versions here are the standard temperature monitoring and a DGS 4 limit switch with four switching points integrated into the electrical housing and driven directly by the drum.

A ZBA hoist motor (also made in Germany by Demag) operates efficiently and can be integrated into state-of-the-art control concepts, such as closed loop with encoder feedback. Other safety functions of the ZBA motor include a separately controllable brake with brake release control and brake adjustment monitoring as well as the option of integrating an impulse generator.

A new feature is the combination of various options into packages for defined applications-for example, high humidity, arctic or tropical climates or corrosive environments such as those found in galvanizing plants. Demag has put together a total of eight equipment packages in which the hoist unit, motor and coating are adapted to the application profile by means of 16 performance features. "This gives the user the certainty that they are selecting the right hoist even in adverse environmental conditions and can expect a long service life," said the spokesperson.

Additional options and improvements are planned for the first half of 2024, including to the rope hoist system and control technology. In this way, a proven concept will be made fit for the future and also for new requirements and areas of application.
