Configurations range from the standard DR COM unit with contactor control or the individually customized DR PRO with electronic control.
The DR20 PRO hoist extends the DR line to capacities up to 50 tons and features wireless infrared control.
The standard DR20 features a range of additional features, while the FDR model is used for crane or plant engineered installations and the EZDR double-rail crab model is a solution for double-girder crane applications.
Used in a wide variety of industries, the DR20 PRO features a “highly efficient” FEM2 classification, provides optimum space utilization, increased hoist speeds and “requires little maintenance,” according to Demag.
The DR20 PRO features a low-vibration, quiet running, two-speed motor engineered for high cycling rates and accurate positioning.
Low current switching extends the contactor life and is controlled by an on-board computer through a service diagnostic feature. A microprocessor provides real-time service and maintenance information that can be accessed from the push-button station LCD screen.
Communication is achieved with the hoist via a laptop or Pocket PC (PDA), with pre-loaded software from Demag, via infrared.
Used in a wide variety of industries, the DR20 features duty classifications ranging from FEM 1 Am to FEM 4 m, capacities from 6.3 to 50 tons, and hoist speeds in a range of 12 FPM to 64 FPM.
