Robopac Helix 4 EVO Pallet Winder (2021)

Robopac Palettenwickler

Overview

This Robopac Helix 4 EVO pallet winder was built in 2021, with less than 500 operating hours - technically close to new.

The arm carries the pre-stretch carriage around the stationary pallet, so the load itself is never turned - the configuration for unstable, fragile or heavy loads at high output (capacity below). Built as a stand-alone unit.
