What is a Stacker? Exploring Essential Material Handling Equipment.

Effective material handling is vital for maintaining productivity and ensuring seamless operations. Understanding the tools available for this purpose is essential. Among the various types of equipment commonly utilised, stackers play an indispensable role in optimising storage and facilitating the safe movement of goods.

What is a Stacker?

A stacker, also commonly known as a pallet stacker or electric stacker, is a piece of material handling equipment designed to lift, transport, and stack heavy loads – particularly pallets – within a warehouse, distribution centre, or retail space.

What types of stackers are commonly available?

Stackers are available in various configurations, including manual, semi-electric, and fully electric models, allowing them to cater to a diverse range of operational requirements. By choosing the right type of stacker for their needs, warehouse managers and operators can effectively manage inventory, maximise vertical space, and streamline operations.

Generally, stackers can be classified into three main categories based on their operational mechanisms: 

• Manual stackers: These rely entirely on human power, making them ideal for lighter loads and occasional use in small environments.
• Semi-electric stackers: Assist operators with electric lifting capabilities while still requiring some manual effort.
• Fully electric stackers: often referred to as pedestrian stackers, these allow for effortless manoeuvrability of heavy loads, significantly enhancing productivity and reducing physical strain on operators.

The Importance of Stackers for Material Handling

Stackers play an important role in material handling. Designed to operate in tight and confined spaces where traditional forklifts may struggle, stackers allow warehouses to make the most of their vertical storage options and significantly increase efficiency. 

In addition to flexibility and space optimisation, stackers place significant emphasis on operator safety. Their design mitigates the risks associated with lifting heavy loads by allowing operators to move pallets from the ground to various heights without excessive physical effort. 

Many electric stackers are equipped with advanced safety features such as speed regulation, automatic braking systems, and stability controls that help minimise accidents.

By prioritising employee safety, stackers not only protect workers but also reduce the likelihood of product and equipment damage, ultimately saving businesses time and money.

Popular Types of Stackers and Their Applications

Understanding the various types of stackers and their applications is essential when planning material handling operations. 

Some common types of stackers include:

1. Manual Stackers: These stackers consist of a simple hydraulic lifting mechanism. They are cost-effective, suitable for lighter loads, and typically used in small warehouses or retail spaces.
2. Electric Stackers: Electric stackers come with advanced electric lifting capabilities and are specifically designed for heavier loads. They help reduce physical exertion, making them ideal for environments with high inventory turnover.
3. Pedestrian Stackers: Also known as walk-behind stackers, pedestrian stackers are fully electric and designed for operators to walk alongside while operating. They provide excellent manoeuvrability, making them suitable for busy environments or tight spaces.
4. Ride-On Stackers: Ride-on stackers allow operators to sit while using the machine, which is advantageous for larger warehouses that require frequent travel distances. They enhance comfort and reduce fatigue during extensive material handling tasks.
5. Straddle Stackers: These are designed to lift and transport loads from both sides with unique straddle legs, offering greater stability and flexibility in handling various pallet sizes. They are particularly popular in industries dealing with diverse inventories.

Choosing the Right Stacker for Your Business

Selecting the right stacker is crucial for optimising efficiency and safety within your warehouse. Key factors to consider include the weight and dimensions of the loads you regularly handle, the layout of your storage space, and the frequency of use. 

For businesses dealing with limited floor space or high shelves, investing in electric and pedestrian stackers may provide the ideal balance of power and agility.

Understanding your operating environment is also essential for choosing the right stacker. If your warehouse features narrow aisles, compact stackers will enhance productivity and support smooth operations. 

Engaging with an equipment specialist or dealer can yield insights into the best options available, ensuring you make the informed decision that best fits your company’s requirements.
