HaiPick A42-E6S Review: Specs and Uses of the Grappling-Hook Tote Robot
Updated: 7 days ago

The HaiPick A42-E6S is a case-handling robot from Hai Robotics that pulls totes with a grappling hook instead of clamping them. The manufacturer does not publish a price. This review covers its specifications, design and uses.
Quick Verdict
A clamp needs space on both sides of a tote. A hook does not: it catches the front of the tote and draws it out. The A42-E6S uses this to pack totes with 30 mm between them sideways and none front to back, and to store three deep. Hai states up to 150% more storage density with triple-deep storage and up to 30% better handling efficiency. The robot carries up to 300 kg in total, with totes of 30 kg as standard or 50 kg customized, and is designed for buildings with less than 6 m clear height. A guard board on the rack positions the totes, so they need no QR codes.
