Robopac Helix 4 EVO Pallet Winder (2021)

Overview

This Robopac Helix 4 EVO is an automatic rotating-arm stretch wrapper for pallet loads, built in 2021. It has less than 500 operating hours and is 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. Throughput reaches 82 pallets per hour at 11 wraps and 1,000 mm load height, 73 at 15 wraps and 1,600 mm, and 64 at 19 wraps and 2,000 mm. The machine has an integrated roller conveyor and was built as a stand-alone unit, loaded and unloaded by forklift.
