Rocla SST/SSI Electric Ride-On Stacker Truck

Rocla SST/SSI electric stacker truck for confident pallet stacking in tight warehouse aisles

If your warehouse is busy, space is limited and pallets still need to move smoothly, the truck you choose matters. The Rocla SST/SSI support-arm (straddle) electric stacker trucks (electric pallet stackers) are made for day-to-day pallet work: stacking, short transfers between zones, and reliable put-away to racking in retail, wholesale and industrial warehouses.

Rocla’s stacker design focuses on stability and predictable handling. A low centre of gravity helps the truck stay steady under load, and the combination of high residual capacity, hydraulic side supports and fast lift/lower movements supports safe, productive work throughout the shift.

Two ride-on formats

Both series cover the same core task: moving and stacking palletised goods efficiently. The key difference is the operator position and how you use the truck during the day. As a ride-on stacker truck, each model is designed to combine stacking performance with direct operator control in day-to-day work.

Rocla SST: stand-in stacker

The Rocla SST is a stand-in electric stacker truck with compact dimensions and excellent agility, making it a strong choice where space is tight and work cycles are frequent. The small turning radius helps when you need to turn in narrow aisles, work around pick faces or move pallets between staging and racking without wasting time.

Rocla SSI: sit-on stacker

The Rocla SSI is a sit-on electric stacker truck designed for more continuous, intensive work. A seated driving position supports operator comfort when the truck is used for longer runs or across larger warehouse zones. SSI models can be specified with quick battery change, which is useful when you run multiple shifts and need to reduce downtime between operators.

Why choose an electric stacker truck for indoor work?

For many warehouses, an electric stacker truck or electric pallet stacker is the most practical way to combine lifting performance with a clean, quiet working environment. Compared with diesel or gas trucks, electric models often mean lower day-to-day running costs and less routine maintenance, while still delivering strong performance for stacking and internal transport. The low noise level also helps reduce fatigue in busy indoor operations.

Key features that improve safety and productivity

The Rocla SST/SSI concept is built around stable handling at height and quick, predictable movements.

• Electric drive for efficient, low-noise indoor operation
• Support-arm (straddle) design for stability and manoeuvrability
• Low centre of gravity to support controlled handling
• Hydraulic side supports and high residual capacity for confident lifting at height
• High lift and lower speeds to improve daily throughput
• Compact turning radius to work efficiently in narrow aisles
• Several mast and battery options to match your lift height and shift needs

Model overview and specifications

Rocla SST and SSI electric pallet stacker trucks are available with different capacities and lift heights. The figures below help you match the truck to your load weights and storage height.

Stand-in support-arm stacker: Rocla SST

Rocla SSTac is a stand-in stacker truck with compact dimensions and high residual capacities. With hydraulic side supports, heavy loads can be lifted safely to higher levels.

Sit-on support-arm stacker: Rocla SSI

The sit-on Rocla SSI stacker is built for intensive work. Support-arm stackers are available in 1500 kg and 2000 kg capacities. A small turning radius and hydraulic side supports help maintain high residual capacities even at higher lift heights. The quick battery change system supports efficient multi-shift operation.

How to choose between SST and SSI

Choose Rocla SST when agility is the priority. The stand-in format suits frequent short movements, tight turning spaces and operations where the truck is constantly stopping, lifting, lowering and moving again.

Choose Rocla SSI when the truck is used intensively and travel distances are longer. The sit-on position supports comfort, and the ability to specify quick battery change helps when you run multiple shifts and want to keep the truck in productive use.

Other Rocla pallet stacker options

If your application is different, Rocla’s stacker range also includes pedestrian and platform models for pallet stacking and transport. For example, compact pedestrian stackers (such as Rocla SWS) can be a good fit for very tight areas, while platform stackers (such as Rocla SPE/SP) can be useful when longer internal moves are common. If you tell us your pallet weights, lift height and aisle width, we can help point you towards the right type of stacker truck.
