Anti-Sway and Safety Design for Ultra-High Heavy-Duty Pallet Stacker Cranes

When a Pallet Stacker Crane operates at 31.6 m height and handles load units up to 2,500 kg, safety and stability become central engineering issues. The challenge is not only lifting the load, but also controlling vibration, reducing impact, monitoring operation, and protecting goods and equipment during continuous high-bay operation.

In a DELIECN battery aluminum foil project, anti-sway and safety design were key parts of the ultra-high heavy-duty pallet Stacker Crane System.

Why Anti-Sway Design Is Necessary

High-bay stacker cranes may generate vibration during travel, lifting, deceleration, and fork movement. The higher the mast and the heavier the load, the more important vibration control becomes.

For this project, the Stacker Crane needed to handle oversized and heavy materials at 31.6 m height. The maximum load reached 2,500 kg. Without effective anti-sway design, load movement may affect positioning stability, equipment safety, and system efficiency.

Servo Drive Optimization

The stacker cranes used asynchronous servo motors. Through parameter adjustment, the system improved stability during acceleration, deceleration, lifting, and positioning. This helped reduce impact and vibration caused by speed changes, especially when handling heavy load units.

Video Monitoring

Each stacker crane was equipped with monitoring cameras on both sides. Operators can observe inbound and outbound operation, goods status, carrier position, and aisle conditions from the control room.

This improves abnormal situation detection and helps the operation team respond quickly when needed.

Fire Extinguishing System

The stacker crane load platform was equipped with a fire extinguishing system. A ground control cabinet was installed at the aisle end.

If a fire occurs in a storage location, operators can move the stacker crane to the specified position and activate the fire extinguishing device through the ground control cabinet for emergency handling. This design was selected according to the customer's material characteristics and storage safety requirements.

Mechanical and Operational Safety

The equipment also included multiple safety devices, such as:

• Staggered anti-collision buffers at the top and bottom
• Fall protection mechanism
• Storage location empty/occupied detection
• Load deviation detection
• Emergency stop devices

Cleanliness Protection

The project also configured dust removal at the inbound entrance. During inbound handling, the system cleans the external packaging of materials to reduce dust and impurities before storage. For battery aluminum foil materials, this supports cleaner storage and helps protect material quality.
