Miniload Stacker Crane
A Miniload stacker crane is a fully automated machine used in high-density warehouse systems to store and retrieve small unit loads, such as boxes, trays, or totes. Often referred to simply as a “Miniload,” these cranes operate within narrow aisles of high-bay racking to maximize vertical space and throughput without human operators.
Designed for automated storage and retrieval of small unit loads like bins, totes, or cartons weighing 20–100 kg, ideal for high-density storage in e-commerce, pharmaceuticals, and spare parts warehouses.
Utilizes a lightweight single vertical mast with a telescopic extractor or gripper, enabling operation in narrow aisles (0.8–1.2 m wide) and heights up to 12–18 m for optimized space utilization.
Achieves horizontal speeds of 3–5 m/s and vertical speeds of 1–2 m/s, supporting 100–300 cycles per hour per crane to meet fast-paced order fulfillment demands.
Equipped with customizable extractors (e.g., vacuum, clamp, or finger grippers) for handling diverse container shapes and materials, including ESD-safe options for electronics.
Incorporates regenerative braking and low-friction rails to minimize power usage, often reducing consumption by 20–40% compared to heavier stacker cranes.
