PS Compact pedestrian stacker

The Alto PS is a robust, powerful, handy pedestrian stacker for flexible use in tight spaces, suitable for handling “open” load carriers.

Ideal for use in tight spaces, this compact pedestrian stacker is designed for stacking, occasional order picking and short distance internal transportation. The low chassis and the offset tiller arm improve visibility and safety – the operator has a clear view of the load and can walk beside the truck.

The ergonomic tiller head is designed for ambidextrous use and features easily accessible controls to facilitate handling. Are you picking up and putting away pallets in very confined areas? Then the Tiller Up drive option with the tiller arm in the upright position makes it possible to work in even tighter areas.
Top versatility up to 3590mm

The Alto PS is a robust, versatile, easy to use truck for different material handling operations such as internal transportation, order picking and stacking up to 3590 mm.

Masts for maximum control and visibility

UniCarriers two clear view masts – the TV telescopic with maximum vision or the TFV telescopic with maximum vision and free lift – combined with the offset tiller arm ensure full visibility over the fork and load. The precise proportional lifting and lowering functions give the operator full control over the load and fork movements


The offset tiller arm makes it possible for the operator to walk beside the truck. This gives full visibility over the fork and load and reduces the risk of foot injuries. The offset tiller arm features a display and keypad for PIN code entry. Three different operator category settings ensure the operator has access to the right performance depending on driving skills and prevents unauthorised use. The ATC T4 controller, including an advanced fault code function, contributes to fast trouble shooting.


The narrow, short and round edged chassis allows the operator to pick up and position pallets in very confined spaces – especially important in production and other confined areas. The rounded edges also minimise the risk of damaged goods, while the low bumper on the short chassis prevents foot injuries.

For even better space utilisation, there’s the option of Tiller Up drive.

Shared components for maximum uptime

The PS is modular built with UniCarriers unique shared components concept. It shares parts with the PLL Piccolo, PSL Solo, PSD Doppio and PSH Alto – this maximises both uptime and First Time Fix Rate. What’s more, the brushless AC motor extends the service intervals
