Choosing the right electric stacker is important for improving warehouse efficiency, reducing manual handling, and making better use of available storage space. However, with different load capacities, lifting heights, mast configurations, operating types, and tire options available, choosing the right electric stacker for your warehouse can be challenging.

The best electric stacker is not necessarily the one with the highest capacity or lifting height. Instead, it should match your load requirements, pallet type, lifting height, warehouse layout, floor conditions, operating frequency, and working environment.

In this guide, we explain the key factors to consider when choosing an electric stacker and how to select the right configuration for your material handling application.

What Is an Electric Stacker?

An electric stacker is a material handling machine designed to lift, transport, and stack palletized goods.

Unlike manual stackers, electric stackers use an electric power system to assist or perform the lifting and/or traveling functions. Depending on the design, electric stackers can be used for pallet transportation, warehouse storage, production material handling, and vertical stacking.

Common electric stacker configurations include:

• Walkie electric stackers

• Stand-on electric stackers

• Full electric stackers

• Rough terrain electric stackers

• Different mast configurations

• Different lifting heights

• Different load capacities

For warehouses with frequent pallet handling requirements, an electric stacker can reduce repetitive manual work and improve material handling efficiency.

1. Determine the Required Load Capacity

The first factor to consider when choosing an electric stacker is load capacity.

You should determine the maximum weight of the pallets and goods that the machine needs to handle.

For example, if your typical pallet weighs around 1,000 kg, a 1.5-ton electric stacker may provide sufficient capacity. If your pallets frequently approach 2,000 kg, a 2-ton electric stacker would be a more appropriate choice.

Geerdun's electric stacker range can be organized around different load capacities, including:

However, rated capacity alone is not enough to determine whether a stacker is suitable.

You also need to consider the load center.

2. Check the Load Center

The load center describes the horizontal distance between the fork face and the center of gravity of the load.

For many of the electric stacker configurations discussed on our website, the standard load center is 500 mm.

For example:

2,000 kg rated capacity + 500 mm load center

means the machine's rated capacity is specified under that load-center condition.

If the actual load center is greater than the rated load center, the available lifting capacity may be reduced.

Therefore, when choosing an electric stacker, always check:

• Rated load capacity

• Load center

• Pallet dimensions

• Load distribution

• Lifting height

This is especially important when handling long, oversized, or irregularly distributed loads.

3. Choose the Correct Lifting Height

The next important question is:

How high do you need to lift the pallet?

Electric stackers are available with different lifting heights depending on the mast configuration.

Typical lifting heights may include:

• 2,000 mm

• 2,500 mm

• 3,000 mm

• 3,500 mm

• 4,000 mm

• 4,500 mm

• 5,000 mm

• 5,500 mm

The correct lifting height should be based on the highest storage position you need to reach rather than simply choosing the maximum available height.

Low-Level Stacking: 2.0–2.5 m

Suitable for:

• Low storage areas

• Production workshops

• Pallet transfer

• Low-level stacking

Standard Stacking: 2.5–3.5 m

Suitable for:

• General warehouses

• Standard pallet racks

• Factory storage

• Distribution areas

Medium-Height Stacking: 3.5–4.5 m

Suitable for:

• Medium-height pallet racking

• Factory warehouses

• Higher storage areas

High-Level Stacking: 4.5–5.0 m

Suitable for:

• High-level pallet storage

• Distribution centers

• High-bay storage

Extra-High Stacking: 5.0–5.5 m

Suitable for:

• High-density storage

• High-bay warehouses

• Vertical pallet storage

4. Consider the Mast Type

The lifting height is closely related to the mast type.

Depending on the required lifting height, electric stackers can use different mast configurations.

Simplex Mast

A Simplex mast is generally suitable for lower lifting heights and applications where overhead clearance is limited.

Typical applications include:

• Low-level stacking

• Production areas

• Low storage locations

• Areas with limited vertical clearance

Duplex Mast

A Duplex mast provides a higher lifting range and is commonly used for standard warehouse pallet storage.

Typical applications include:

• Warehouse racking

• Factory storage

• Standard pallet stacking

• Medium-height storage

Triplex Mast

A Triplex mast is suitable for higher lifting requirements.

Typical applications include:

• High-bay warehouses

• High-level pallet racking

• High-density storage

• Extra-high stacking

When selecting a mast, do not only consider the maximum lifting height. You should also check the mast height when lowered/static height to ensure that the equipment can operate safely under doors, beams, ceilings, and other overhead structures.

5. Choose Between Walkie and Stand-On Operation

Another important decision is the operating type.

Electric stackers can generally be designed for walkie operation or stand-on operation.

Walkie Electric Stacker

A walkie electric stacker is operated by the operator walking behind or beside the machine.

It is suitable for:

• Short-distance material handling

• Smaller warehouses

• Lower-frequency pallet movement

• Applications requiring simple operation

The compact structure makes walkie stackers suitable for many warehouse environments.

Stand-On Electric Stacker

A stand-on electric stacker allows the operator to ride on the machine during travel.

This is particularly useful when the operator frequently moves between different locations.

Stand-on stackers are suitable for:

• Large warehouses

• Manufacturing facilities

• Logistics centers

• Frequent pallet transportation

• Longer travel distances

For applications involving repeated pallet movement, a stand-on electric stacker can improve operator efficiency by reducing unnecessary walking.

6. Decide Whether You Need a Full Electric Stacker

If your goal is to reduce manual labor as much as possible, a full electric stacker is an important option to consider.

A full electric stacker uses electric power for both:

Travel + Lifting

This eliminates the need for manual pushing and manual lifting during normal operation.

Advantages of full-electric operation include:

• Reduced physical effort

• Smooth travel

• Electric lifting

• Improved operator comfort

• Higher handling efficiency

• Reduced repetitive manual work

For warehouses with frequent pallet transportation and stacking tasks, full-electric equipment can provide a more efficient alternative to manual or semi-electric handling equipment.

7. Consider Your Warehouse Floor Conditions

Floor conditions are often overlooked when selecting an electric stacker.

A conventional warehouse electric stacker may work very well on smooth concrete floors, but some factories and storage facilities have:

• Uneven concrete

• Rough industrial roads

• Outdoor yards

• Loading areas

• Mixed indoor/outdoor working environments

In these applications, a rough terrain electric stacker may be more appropriate.

Geerdun's rough terrain stand-on electric stackers are designed around features such as:

• Solid rubber tires

• Front and rear solid tires

• Strong passability

• Rough-surface adaptability

• Indoor and outdoor operation

• Flexible stand-on operation

This makes them suitable for factories, warehouses, storage yards, loading areas, and other environments where floor conditions are not always perfectly smooth.

8. Choose the Right Tire Configuration

Tires have a direct impact on machine performance and operating environment.

For rough or mixed working conditions, solid rubber tires can provide important advantages.

They offer:

• Good durability

• Puncture resistance

• Strong passability

• Reduced tire maintenance

• Suitability for industrial environments

For smooth indoor warehouse floors, the tire configuration can be selected according to the specific machine model and application.

For outdoor or rough-surface applications, solid rubber tires can provide additional adaptability.

9. Consider the Pallet Type and Size

Not every pallet is the same.

Before choosing an electric stacker, check:

• Pallet length

• Pallet width

• Fork entry direction

• Fork opening

• Pallet weight

• Load distribution

• Single-sided or double-sided pallet design

Different pallet types may require different fork dimensions.

For example, a customer handling standard warehouse pallets may need a different fork configuration from a manufacturer handling oversized industrial pallets.

Therefore, provide the supplier with your actual pallet dimensions before selecting the final configuration.

10. Consider the Working Environment

The right electric stacker depends heavily on where it will be used.

Warehouse & Storage

For standard warehouse applications, focus on:

• Load capacity

• Lifting height

• Mast type

• Turning space

• Pallet compatibility

• Battery working time

Manufacturing

Manufacturing environments may require:

• Higher load capacity

• Frequent pallet movement

• Durable construction

• Flexible operation

• Indoor/outdoor capability

Logistics & Distribution

Logistics operations typically require:

• Frequent transportation

• Efficient travel

• Suitable lifting height

• Stand-on operation

• Reliable battery performance

Retail & Wholesale

Retail and wholesale warehouses may place more emphasis on:

• Compact dimensions

• Flexible handling

• Pallet compatibility

• Easy operation

• Appropriate lifting height

11. Think About Battery Capacity and Working Time

For a full electric stacker, battery configuration is another important consideration.

You should estimate:

• Daily operating hours

• Number of pallet movements

• Travel distance

• Lifting frequency

• Average load weight

• Charging opportunities

A machine operating for several hours per day may require a different battery configuration from one used only occasionally.

When selecting a battery, consider both:

Battery Capacity + Actual Working Intensity

Instead of simply choosing the largest battery available.

12. Consider Operator Comfort and Safety

An electric stacker should not only move loads efficiently. It should also provide a practical and comfortable working environment for the operator.

Important considerations include:

• Operator position

• Stand-on platform

• Control layout

• Steering system

• Visibility

• Emergency stop

• Stable chassis

• Mast stability

• Controlled lifting and lowering

For applications involving frequent operation, operator comfort can directly affect daily productivity.

13. Choose According to Your Actual Application

The best way to select an electric stacker is to start with your actual working conditions.

For example:

Application A: Indoor Warehouse

Choose a Triplex Mast Electric Stacker with the required lifting height and confirmed load capacity at that height.

Electric Stacker Selection Checklist

Before purchasing an electric stacker, check the following specifications:

Why Choose the Right Electric Stacker?

Choosing the correct electric stacker is about more than simply selecting the largest machine.

The right equipment should provide the appropriate balance between:

Load Capacity + Lifting Height + Mast Configuration + Operating Type + Floor Conditions + Pallet Type + Battery Capacity

For example, a 1.5-ton electric stacker may be the better choice for a warehouse handling lighter loads, while a 2-ton or 3-ton electric stacker may be more appropriate for heavier palletized goods.

Similarly, a standard electric stacker may be ideal for smooth indoor floors, while a rough terrain electric stacker with solid rubber tires can provide greater flexibility for outdoor and uneven working environments.
