How to Choose an Electric Pallet Stacker

Picking a stacker sounds simple until you start shopping and run into straddle legs, counterbalance designs, semi-electric models, load-center ratings, and lift-height charts. This guide walks you through the four decisions that actually matter, so you land on the right machine the first time instead of buying twice.

If you already know what you are after, you can jump straight to our electric straddle stackers, counterbalance stackers, or semi-electric stackers. Otherwise, start here.

Decision 1: What type of stacker fits your space and loads?

There are three common electric stacker designs, and the right one comes down to your aisles, your racking, and how heavy your loads are.

Straddle stackers have two legs that reach forward on either side of the load. Those legs give the machine stability without a heavy counterweight, which keeps the truck compact and lets it work in tight aisles. The trade-off: the legs need to straddle whatever you are lifting, so they work best with open-bottom pallets and floor-level stacking. See the full range of straddle stackers here.

One racking note if you are leaning straddle: for the machine to serve pallet racking, your bottom rack beams need to be raised off the floor so the straddle legs can roll underneath the rack. If your bottom beams sit flush on the floor, the legs will not fit and the stacker will not be able to reach the load. It is an easy thing to check before you buy, and an easy fix (raise the bottom beam) if your racking is adjustable.

Counterbalance stackers skip the front legs entirely and use a weight at the rear to balance the load. Because there are no legs in the way, the forks can drive straight up to a rack or a closed-bottom pallet, just like a sit-down forklift. That makes them ideal for loading racks and handling non-standard pallets, at the cost of a slightly larger footprint. Browse counterbalance stackers here.

Semi-electric stackers use a powered lift with manual push-and-steer movement. They are the budget-friendly option for lower-volume work where you do not need powered travel. See the models in our semi-electric collection.

Quick rule of thumb: tight aisles and floor stacking → straddle. Rack loading and odd pallets → counterbalance. Light-duty, cost-sensitive → semi-electric.

Decision 2: How much weight do you actually need to lift?

Capacity is where most buyers over- or under-buy. Walkie stackers commonly handle anywhere from about 2,000 up to 4,000 lbs depending on design, but there is a catch most spec sheets bury: rated capacity drops as lift height increases.

A machine rated at 3,300 lbs near the floor might only safely carry a fraction of that at full mast height. Every stacker has a de-rating curve that shows how capacity falls off as the forks go up. When you compare models, do not just look at the headline capacity number — check the rated capacity at the height you actually stack to, and at your real load center. Buy for your heaviest routine load plus a small safety margin, not for the one outlier pallet you lift twice a year.

Decision 3: How high do you need to reach?

Match lift height to your top usable beam level plus clearance, not to your ceiling. A few practical bands:

• Under ~80″: low-level stacking, staging, and load/unload work.
• ~100–130″: the sweet spot for standard warehouse racking in small-to-mid facilities and back-of-store areas.
• 150″+: high-reach work, only worth it when your racking, ceiling clearance, aisle width, and floor flatness all support stacking that high safely.

Going taller than you need costs more, de-rates your capacity, and can demand flatter floors and wider aisles. If your operation is really about pulling case-level orders from height rather than moving full pallets, an order picker may be the better tool.

Do not forget lowered mast height — the spec that catches people out. Most stackers use a two-stage mast, which means the mast is at its tallest when the forks are all the way down. The higher a unit lifts, the taller it stands collapsed: a 145″ lift model, for example, can have a lowered mast height around 98″ — tall enough that it will not clear a standard interior doorway. Before you commit to a high-lift machine, measure every doorway, overhead obstruction, and truck/trailer opening it has to pass through, and confirm the lowered (collapsed) mast height fits. It is a costly surprise to discover after delivery. If clearance is tight, ask us about lower-mast options — for example, our EKKO EB12E-98Li has a 72″ lowered mast built to fit under standard doorways.

Decision 4: How hard will the machine work each day?

Finally, be honest about duty cycle — how many pallets you move per shift, and how many shifts you run.

• Occasional / single-shift, light volume: a semi-electric or entry full-electric model is plenty.
• Steady single-shift use: a full-electric straddle or counterbalance stacker earns its keep.
• Multi-shift or heavy daily cycling: prioritize battery technology and charging. This is where lithium power changes the math. We cover that fully in our lithium vs. lead-acid guide.

Putting it together

Work the four decisions in order — type, capacity, lift height, duty cycle — and the field narrows quickly. Still not sure? Tell us your aisle width, typical load weight, and stack height, and we will point you to the exact machine that fits. Browse our stackers or reach out and we will spec it with you.
