Zero Based Stocker

A Zero Stocker usually refers to a Zero-Footprint Stocker (ZFS) or a space-saving stocker design used in factory automation — especially in semiconductor, electronics, and smart manufacturing systems.

Key Features

Multi-layer high-capacity design – Supports up to 4 layers for 200mm wafer boxes, with unlimited full-bay length expansion capability.
Large storage capacity – Accommodates approximately 200–300 boxes per bay within a 24-meter bay length.
Lightweight construction – Designed for overhead hanging applications without excessive structural load.
Ideal as an intra-bay near-tool buffer – Provides efficient temporary storage close to production equipment.
Seamless system integration – Easily interfaces with Conveyors, OHT (Overhead Hoist Transport), and Lifters.
Rapid EMO recovery – Equipped with an Absolute Encoder on the X-axis for faster and more accurate system recovery after emergency stops.
Advanced Wireless Power Transmission (WPT) – Utilizes wireless power technology for improved reliability and reduced cable dependency.
Optimized for overhead storage applications – Designed specifically for space-efficient elevated storage environments.
