AI Technical Summary

Technical Problem

Existing lifting devices struggle to prevent stacks of transport containers from tipping over, especially when dealing with inaccuracies in positioning, dimensioning, and shape of the containers, particularly when lifting individual or multiple layers simultaneously, especially with delicate goods like fruits and vegetables.

Method used

A lifting device with a gripping device and a counter-holding device featuring an expandable cushion that exerts a counter-holding force to stabilize the container during lifting, allowing for precise force application and compensation for positioning deviations, using a combination of vacuum grippers and movable fork tines.

Benefits of technology

The device effectively prevents stacks from tipping over, ensures uniform force transmission, and allows for flexible handling of various container dimensions and damage-prone goods, enhancing the safety and efficiency of order picking processes.
