Efficiency in a warehouse isn't just about speed; it's about matching the right tool to the right job. When it comes to lifting pallets and organizing racking, the two most common contenders are the stacker and the reach truck. While they might look similar to the untrained eye—both have forks, both lift heavy loads, and both are essential in logistics—they serve vastly different purposes.
Choosing the wrong equipment can lead to safety hazards, damaged inventory, or wasted budget on features you don't need. Conversely, the right choice streamlines operations and boosts productivity. So, how do you decide? In this guide, we break down the core differences between stackers and reach trucks, exploring their functions, benefits, and ideal use cases to help you make an informed decision for your facility.
A pallet stacker is essentially an upgraded pallet jack. While a standard jack only lifts loads a few inches off the ground for transport, a stacker is equipped with a mast that allows it to lift loads to significant heights. It is designed for small to medium-sized warehousing operations where goods need to be stacked on top of each other or placed into low-to-mid-level racking.
Stackers are generally smaller, more affordable, and easier to operate than larger forklifts. They come in various configurations, including manual, semi-electric, and fully electric models. Because they are often "walk-behind" units (though ride-on models exist), they offer excellent visibility and are less intimidating for new operators.
Compact Design: They have a smaller chassis, making them ideal for narrow aisles and tight spaces.
Lower Lift Heights: Typically designed for lifting up to 5-6 meters (approx. 16-20 feet), though this varies by model.
Cost-Effective: Lower upfront cost and lower maintenance requirements compared to reach trucks.
Walkie or Ride-on: Most are operated by a pedestrian walking behind the unit, although some feature a fold-down platform for the operator to stand on.

A reach truck is a more specialized class of warehouse equipment designed specifically for high-density storage. Its name comes from its defining feature: the ability of the fork carriage to "reach" out into the racking system. This mechanism allows the truck to place and retrieve pallets in double-deep racking configurations, significantly increasing storage density.
Reach trucks are almost exclusively electric and are designed for indoor use on smooth surfaces. They are built to lift heavier loads to much greater heights than a standard stacker. The operator sits or stands in a compartment within the truck, sideways to the direction of travel, which provides a better view when navigating tall aisles.
Reach Mechanism: The pantograph mechanism allows the forks to extend away from the mast.
High Reach Capability: Can lift loads to heights often exceeding 10-12 meters (30-40 feet).
Stability: Designed with outriggers (legs) and a counterweight system that allows for lifting heavy loads to great heights without tipping.
Narrow Aisle Operation: Despite their power, they are designed to turn in very narrow aisles, maximizing warehouse floor space.

To help you visualize the differences, let's compare these two machines across critical operational categories.
Feature | Pallet Stacker | Reach Truck |
|---|---|---|
Primary Function | Stacking pallets, short-distance transport, low-level racking. | High-level stacking, working in narrow aisles, double-deep racking. |
Lift Height | Low to Medium (Typically up to 6m). | High (Can exceed 12m). |
Load Capacity | Generally lower (1.0 - 2.0 tons). | Higher (1.5 - 2.5+ tons). |
Aisle Width | Requires moderate aisle width (approx. 2.2 - 2.5m). | Designed for narrow aisles (approx. 2.7m+, but turns tighter). |
Operator Position | Walk-behind (pedestrian) or standing on a platform. | Seated or standing inside a protective cabin. |
Cost | Lower initial investment and maintenance. | Higher initial investment and maintenance. |
Training | Minimal training required; easier to learn. | Requires specialized forklift certification and more training. |
A stacker is likely the best choice for your business if you are operating a smaller warehouse or a retail backroom. If your vertical storage doesn't exceed 5 or 6 meters, a stacker provides all the utility you need without the hefty price tag of a reach truck.
They are also excellent for "feeder" operations. For example, in large distribution centers, stackers are often used in the staging area to organize pallets before they are moved by larger trucks. Because they are smaller, they are easier to maneuver in congested loading docks.
Ideal scenarios for a Stacker:
Small storage rooms or retail floors.
Warehouses with low-level racking systems.
Operations with budget constraints.
Environments where operators need to hop on and off frequently.
If maximizing cubic footage is your priority, an electric reach truck is the superior option. In logistics, floor space is expensive. By building racking higher and using narrower aisles, you lower your cost per pallet position. Reach trucks make this vertical expansion possible.
The "reach" capability is also crucial if you use double-deep racking (storing one pallet behind another). A standard stacker cannot access the rear pallet, whereas a reach truck can extend its forks to grab it. Furthermore, reach trucks are built for high-volume shifts. They have larger batteries and faster lift speeds, meaning they can move more pallets per hour than a stacker.
Ideal scenarios for a Reach Truck:
Large distribution centers with high-bay racking.
Warehouses using double-deep storage systems.
Operations requiring high-speed pallet movement.
Narrow aisle configurations where turning radius is critical.

Safety is paramount when operating any material handling equipment. Due to the differences in design and operation, the safety protocols for these machines differ.
Stacker Safety:
Since the operator is often walking with the machine, the primary risk is foot injuries. Operators must ensure their feet are clear of the machine's chassis. Visibility is generally good, but operators must be careful when turning corners in busy aisles.
Reach Truck Safety:
Reach trucks are heavier and lift loads much higher, introducing the risk of tip-overs if not operated correctly. The "center of gravity" changes as the load is lifted and extended. Operators require specialized training to understand load charts and stability triangles. Additionally, because operators are seated or standing sideways, they must be vigilant about checking blind spots.
Ultimately, the choice between a stacker and a reach truck comes down to three factors: height, volume, and budget.
Height: If you need to go above 6 meters, you need a reach truck.
Volume: If you are moving hundreds of pallets a shift, the speed of a reach truck will pay for itself. If you are moving a few dozen, a stacker is sufficient.
Budget: If capital is tight and your storage requirements are modest, the stacker is the economical winner.
