PreFeeder 4850

PreFeeder 4850
Powerful cable feeding system for reels weighing up to 600 kg (1320 lbs.).


The PreFeeder 4850 is a powerful cable feeding system for reels weighing up to 600 kg (1,320 lbs.). The system distinguishes itself through its simple design and ease of use. For easy reel handling and fast changeovers, all axes are electrically driven. The PreFeeder 4850 uses a shaftless design for easy loading and unloading of reels.

The integrated cable accumulator controls the speed of the dereeling drive. Surveillance functions provide enhanced security during set-up and operation. With this concept a cost efficient solution for a wide range of applications is achieved.
