Paper Roll Vacuum Lifter

Product catalog summary

Overview: The document is a product sheet for Konecranes Paper Roll Vacuum Lifters, designed for handling various paper grades and roll sizes safely and efficiently. It highlights the specifications, safety features, intelligent functions, and maintenance aspects of the vacuum lifters.

Specifications: The vacuum lifters are available in three series: VLU12, VLU15, and VLU19, each with different bottom plate sizes and lifting capacities. The dimensions and weight vary across the series, with the VLU19 being the largest and heaviest. The lifters are designed to handle rolls with diameters ranging from 600 mm to 2100 mm.

Safety Features: The lifters are equipped with two independent vacuum pumps for redundancy and increased suction capacity. A processor calculates the necessary vacuum level to ensure a safety factor greater than 2.0. The system includes continuous monitoring of vacuum levels and has backup power options like UPS or generators to ensure safety during power outages.

Positioning and Collision Avoidance: The lifters use distance and position sensors to ensure collision avoidance during automatic operations. Manual operations are supported by position sensors and indication lights to assist in roll pickup.

Intelligent Functions: Features include wireless data transmission, detection of two roll gripping, fast gripping for small rolls, and handling of jumbo rolls. Vacuum trend monitoring aids in optimizing maintenance schedules.

Maintenance: The design includes hinged electric boxes and plug-fitted components for easy maintenance. Each lifter comes with a maintenance stand that also serves as packing during transportation.
