Application
The DR 724 P Spreader is for use in reeling applications with heavy duty mechanical stress e.g. in motor driven drums in container cranes.
Outstanding features
- path feed rate up to 240 m/min.
- high winding and unwinding strength EN
- for high mechanical stress in reeling processes
- flame retardant and self-extinguishing
- small outer diameter
- small cable weight
