Pallet stackers are essential material handling equipment used in warehouses, factories, and various other industrial settings. These versatile machines are designed to move, lift, and transport palletized loads efficiently and safely. Whether you need to load or unload trucks, transfer goods within your facility, or organise your inventory, pallet stackers can streamline your operations and boost productivity.
What are pallet stackers and their uses?
Pallet stackers are equipment used for lifting and stacking pallets vertically. They come in two main types: manual and electric.
- Manual Pallet Stackers are designed for vertical lifting and stacking. They require manual effort to operate and are ideal for situations where a simple, cost-effective solution is needed. While they can be used in tight spaces, they are primarily focused on vertical movement rather than long-distance transportation. Hand Pallet Trucks or Pallet Jacks, often confused with manual pallet stackers, are actually used for horizontal movement of pallets. They are also manual and excellent for navigating tight spaces, but they are not designed for vertical stacking.
- Electric Pallet Stackers are powered by an electric motor and batteries, allowing for effortless transportation and vertical stacking of heavy loads over longer distances. They are ideal for high-frequency operations where efficiency and speed are crucial.
How manual stackers work
Manual pallet stackers, also known as hand pallet trucks or manual pallet jacks, are simple yet effective tools for moving palletized loads. The operator positions the stacker's forks underneath the pallet and uses a hydraulic pump mechanism to raise the forks slightly off the ground, lifting the pallet. Then, the operator manually pushes or pulls the stacker, transporting the load to the desired location. To lower the pallet, the operator releases the hydraulic pump, allowing the forks to descend gently.
Key features of manual stackers

If you have a high volume of material handling tasks or need to move heavy loads frequently, manual stackers may not be the most practical or ergonomic solution, as they can increase the risk of operator fatigue and injury.
How electric stackers work
Electric pallet stackers, also known as powered pallet trucks or electric pallet jacks, are designed to make material handling tasks more efficient and less physically demanding. They work as follows:
- The operator positions the stacker's forks underneath the pallet.
- Using a control, typically a tiller arm or button, the operator activates the electric motor.
- The motor raises the forks, lifting the pallet off the ground.
- The operator then guides the stacker, using the tiller arm or handle, to transport the load to the desired location.
- To lower the pallet, the operator reverses the control, allowing the forks to descend gently.
Electric stackers are powered by rechargeable batteries, which provide the necessary energy for lifting and manoeuvring loads. Depending on the model, they can accommodate a wide range of pallet and load sizes and weights.
