The LANCMAN STAWX 21 wood splitter is a robust and powerful mobile vertical splitter on a homologated trailer, designed for demanding users and professional use. With a splitting force of 21 tons, it easily splits even harder and larger logs up to Ø 80 cm in diameter and 117 cm in length.
Thanks to its road homologation, the STAWX 21 is easy to transport and can be used directly on site – in the forest, in the field, or for home firewood preparation.
Available drive versions:
petrol engine – for complete independence at work
electric motor – for quiet and energy-efficient operation
combined drive – for maximum flexibility and constant availability
The splitter is standardly equipped with two splitting speeds (manual control), and optionally with the MULTISPEED system, which automatically adjusts the speed to the load – faster operation with lighter logs and slower, but with more power, with thicker ones.
The STAWX 21 features a strong construction, a stable design, and safety solutions compliant with EN standards, ensuring safe operation and long service life even in the most demanding professional applications.
Designed and manufactured in Slovenia.

The tonnage rating indicates the maximum force that the hydraulic cylinder can generate during splitting. The wedge (axe) presses directly onto the log and splits it. For the splitter to reach its full force, the wedge must be braced against a solid, fixed stop, which allows the hydraulic pressure to be converted into actual splitting force.
Technically, the force of a splitter is measured in kiloNewtons (kN). Example:
1 kN = approximately 0.102 tons of force
200 kN ≈ 20 tons of force
This means that a 20-ton rating corresponds to about 200 kN of pressure exerted by the wedge on the log. The actual force applied, however, is proportional to the resistance of the wood – softer logs require less pressure, while harder or knotty logs require more.
