Demag DH hoist units can be used in a wide variety of applications, both as travelling hoists on cranes or monorails and as stationary solutions. These powerful hoist units offer a number of special technical features that enable loads to be handled reliably even under demanding requirements. More than lifting: Installed as stationary or travelling units, they are more than just hoists – thanks to gentle handling with high load capacities up to 100 tons and flexible integration into almost any design.
DH hoists are robust to ensure reliable operation even in the toughest environments. Demag hoist units are designed for demanding applications such as foundries or electroplating plants with high ambient temperatures, high dust levels and aggressive environments. They can also withstand the adverse conditions typically encountered by rope hoists.
Their modular concept and flexible mounting arrangements enable DH hoist units to be integrated into almost any structure with ease. Their many variants and options facilitate an almost unlimited range of applications. For example, you can find these hoists in lifting stations, winch arrangements and architectural applications – sometimes it takes a closer look to even discover them.
Demag DH hoist units are based on perfectly matched and robustly designed components. This means that they offer optimum conditions for individual solutions, even for unusual applications. Demag DH hoist units are in operation all over the world and offer outstanding safety and reliability.
Precise. Rugged. High performance. For our DH hoist range, we offer three different drive concepts that have proven themselves in a wide range of applications. Based on reliable series components, lifting solutions can be specifically configured for any requirement. With the “Made in Germany” seal of quality.
Our conical-rotor brake motors with outputs of up to 40 kW are used as starting/stopping drives. The pole-changing motors have two speeds and work reliably even with extremely high switching frequencies. The mechanical connection between the conical brake and rotor creates a unique braking principle with high braking capacity. This makes these motors superior wherever the highest demands are placed on the brake. Separate control and additional switching elements are not required. The sliding-rotor motors are equipped with motor temperature monitoring as standard.
The combination of our ZBA cylindrical-rotor brake motors with Dedrive Compact frequency inverters creates powerful lifting units with infinitely variable speeds. And they offer impressive performance:
Demag DH hoist units are safeguarded by specially designed rope guides that offer reliable protection against extreme load conditions such as inclined pull, load sway, and rope vibrations. Made from tough, wear-resistant plastic, these rope guides can withstand inclined pulls of up to 4° without contact. They are two-part units that are easily replaceable without special tools. Reinforced versions are available for demanding applications.
