Accessories
Pallet decoiler
The Wieland Pallet Decoiler is an innovative and self-regulating system to decoil level-wound copper tubes of approx. 5 - 25 mm.
This easy and fast setup considerably reduces downtime at the next machine (e.g. cut-to-length or bending line). It also reduces the risk of damage of the tubes during in-house handling. It improves safety significantly as the coils remain on the pallet during the entire process.
Your benefits
- optimized setup times
- easy decoiling
- high safety
- no scrap due to the handling of coils
- easy and fast change of different tube sizes
- total footprint of the line can be reduced
- material storage is combined with the decoiling system
- no crane required
- high flexibility
LWC handling system
Using this system level-wound copper tubes can be processed without the usual coil packaging (cardboard reels).
Available as a complete system or a choice of: decoiling adapter, lifting strap and beam traverse.
Your benefits
- reduction of packaging waste
- more cost-effective without packaging
- coil weights up to 300kg possible
- longer machine run times
- considerably less handling required
