100–1000 KG Automatic Big Bag Stacking Machine

Product Introduction

This automatic big bag stacking machine is designed for stacking filled FIBCs, especially suitable for materials with low air content or applications requiring stable stacking. It features a single-motor lifting system for smooth and reliable operation, with a strong structure and a maximum lifting capacity of 3 tons. Equipped with a safety anti-drop plate, it ensures safe handling during operation. The automated stacking and pallet return system improve efficiency, stacking accuracy, and reduce manual labor and overall costs. It is widely used in industries such as mining, lithium iron phosphate (LFP), ternary materials, graphite, construction materials, grain, and feed.

Features

Single-motor lifting for stable operation, high-strength structure with up to 3T lifting capacity, anti-drop safety plate, optional rotating roller pallet return system, improved stacking accuracy and efficiency, and reduced labor, transportation, and storage costs.

Problems Solved
Effectively solves issues such as unstable lifting, insufficient load capacity, and safety risks during stacking. The anti-drop design prevents bag falling when no material is being filled. It also optimizes pallet return, reduces manual handling, improves stacking consistency, and lowers overall operational costs.

Applicable Materials

Suitable for stacking 100–1000 kg big bags containing ultra-fine powders and various bulk materials. Common materials include graphite powder, lithium battery materials (LFP, cathode and anode materials), minerals, construction materials, grain, and feed. Ideal for applications requiring low air content and integration with downstream shaping or strapping lines.

Typical Industries

New energy battery, fine chemical and advanced materials, pharmaceutical, food, powder & functional materials, mineral & inorganic materials, and energy & environmental protection industries.
