Stackers, also known as stacking machines or pallet stackers, are essential material-handling equipment used in warehouses, factories, and logistics operations. They are designed to lift and stack pallets or heavy loads efficiently. The materials used in their construction depend on the type of stacker (manual, semi-electric, or fully electric) and the intended application. Below, we explore the common materials and components that make up stackers.

1. Frame and Chassis

The frame is the backbone of a stacker, providing structural support and stability. It is typically made from:

High-Strength Steel – Used in heavy-duty stackers for durability and load-bearing capacity.

Aluminum Alloys – Found in lightweight stackers for easier maneuverability and corrosion resistance.

Reinforced Plastics or Composites – Used in some modern, ultra-lightweight models to reduce weight while maintaining strength.

2. Mast and Forks

The mast is the vertical assembly that allows the stacker to lift loads, while the forks hold the pallets. These components are usually constructed from:

Hardened Steel – Ensures rigidity and resistance to bending under heavy loads.

Stainless Steel – Used in food-grade or chemical environments to prevent rust.

Telescopic Channels (for height adjustment) – Made from precision-machined steel or aluminum for smooth operation.

3. Wheels and Tires

Stackers rely on wheels for mobility, which can be made from:

Polyurethane (PU) – Durable, non-marking, and suitable for indoor use.

Nylon or Hard Plastic – Used for lightweight stackers on smooth surfaces.

Rubber or Pneumatic Tires – Provide better shock absorption for outdoor or rough terrain.

4. Hydraulic and Electrical Components

Hydraulic Cylinders – Made from steel with chrome-plated rods for smooth lifting.

Electric Motors (in powered stackers) – Typically contain copper windings, aluminum housings, and rare-earth magnets.

Batteries (for electric models) – Usually lead-acid or lithium-ion for power efficiency.

5. Control Systems and Safety Features

Handle and Controls – Made from durable plastics or rubber-coated steel for ergonomic use.

Safety Guards – Often constructed from steel or impact-resistant plastic.

Circuit Boards and Sensors – Made from fiberglass, copper, and silicon for reliable operation.

Conclusion

Stackers are built from a combination of high-strength metals, durable plastics, and advanced electrical components to ensure efficiency, safety, and longevity. The choice of materials depends on the stacker’s type, load capacity, and working environment. Whether manual or electric, a well-constructed stacker enhances productivity in material handling operations.
