The DR 20 has a new limit switch based inside the drum. Information from the switch feeds directly into the controls. It also features brake monitoring, phase error recognition and
The square-mounted drum unit can also be mounted on a trolley in four orientations, so that the rope path can emerge from behind, above, in front, and below the hoist. The hoist is sold without electrical controls as a kit or as a complete crane.
When the hoist goes on sale in January, the DR 3, 5, and 10 hoists will have replaced the DH range completely.
In the Pro-Hub system, a frequency inverter measures the slip on the hoist. If the hook is empty, it increases the speed of lifting to return the hook quickly.
Demag is planning to launch the DR 20 hoists in the USA next year at NA 2006, 27-30 March.
