PROFESSIONAL VERTICAL LOG SPLITTER LANCMAN STX 21 – Power and Efficiency for Heavy-Duty Needs

The vertical log splitter LANCMAN STX 21 is a powerful machine designed for users who require high splitting force and professional productivity in firewood preparation.
With a splitting force of 21 tons, it easily splits even the largest and hardest logs up to Ø 80 cm and 117 cm in length.

Available in different drive versions:

  • C – PTO drive

  • EL – electric drive

  • C+EL – combined drive (PTO + electric) for maximum flexibility

The splitter comes as standard with two manually controlled splitting speeds. Optionally, it is available with MULTISPEED, which automatically adjusts the splitting speed for greater efficiency. For the electric version, the XTREMSPEED system can be installed, providing up to 50% faster splitting.

The vertical design ensures easy handling of logs of various sizes.
The STX 21 MULTISPEED features a strong construction, advanced hydraulic system, and a HARDOX splitting wedge for longer service life and improved splitting performance.
Safety solutions in compliance with EN standards ensure safe operation even in professional environments.

Designed and manufactured in Slovenia.

Frequently Asked Questions

"What does 'ton splitting force' (e.g. 20 tons) mean in log splitters?"

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.

"What log size (diameter and length) can the log splitter process?"
"Which log splitter should I choose depending on the type of drive – electric or petrol/hydraulic? What is the power source?"
