1500KG | Electric Stacker WS15-B
Komada WS15-B Fully Powered Stacker lifts up to 4.0 m with 1.5 ton capacity. Standard lift speed, Light Grey & Black.
WS15-B 1500kg Electric Stacker (2.0 – 4.0 m Lift)
The KOMADA WS15-B is a 1500kg electric stacker with fully powered drive and lift, and six lift heights from 2.0 m to 4.0 m. Because both driving and lifting are battery powered, operators stack pallets onto racking without pushing or pumping by hand. In addition, its 820 mm overall width and 1,425 mm turning radius make it easy to work in narrow warehouse aisles.
It is also the standard-speed version of the WS15 series. In other words, a 2.2 kW lift pump motor gives standard lifting and lowering, while the WS15-A adds a larger 2.5 kW motor with variable-speed lifting. So, choose the WS15-B when standard lifting speed is enough for your workflow.
Key Features & Benefits
Standard Lifting Speed
A 2.2 kW lift pump motor gives steady lifting and lowering, so it suits everyday stacking.
Light Grey & Black Finish
Also, the neutral colour suits sites that match equipment to a clean, corporate or retail-facing look.
Compact & Easy to Steer
Because the steering angle is above 180° and the tiller is low-mounted, operators steer with less effort in tight spaces.
Intelligent Tiller Handle
Battery level and fault codes show on the handle display. As a result, faults are found quickly and service time is shorter.
Built-In Safety
In addition, an electromagnetic brake and DC speed control keep travel smooth and controlled.
Easy Charging
The built-in charger includes external cable storage. The standard battery is 24V/71Ah maintenance-free lead-acid; however, a larger or lithium battery is also available.
Low Mast on Shorter Models
For example, models under 3.3 m lift suit containers and goods lifts.

Key Features
Frequently Asked Questions
What is the difference between the WS15-A and WS15-B?
The main difference is lifting speed. The WS15-A has a larger 2.5 kW lift pump motor with variable-speed lifting and lowering, whereas the WS15-B has a 2.2 kW motor with standard speed. Otherwise, capacity, lift heights and chassis are the same. In addition, the WS15-A is Yellow & Black, while the WS15-B is Light Grey & Black.
Which should I choose, WS15-A or WS15-B?
Choose the WS15-A if you move many pallets per shift or need adjustable lifting speed. On the other hand, choose the WS15-B if standard lifting speed is enough for your workload.
What is a fully powered stacker?
It is a walk-behind electric truck that both drives and lifts pallets on battery power. In contrast, a semi-electric stacker only lifts electrically, so it must be pushed by hand.
How much can the WS15-B lift?
The rated capacity is 1,500 kg. However, capacity reduces at higher lift heights, so tell us your pallet weight and racking height and we will confirm the right model.
What aisle width does it need?
For 1000 × 1200 mm pallets crossways, it needs 2,268 mm. Similarly, 800 × 1200 mm pallets lengthways need 2,194 mm.
Which models are in stock?
WS1530-B (3.0 m), WS1535-B (3.5 m) and WS1540-B (4.0 m) are in stock. Other heights, however, are available on pre-order.
Not Sure Which Lift Height You Need?
Simply send us your racking height and pallet weight, and then our specialist will recommend the right model.
