PROFESSIONAL VERTICAL LOG SPLITTER LANCMAN STX 21 MULTISPEED – Maximum Power with Advanced Speed Control

The vertical log splitter LANCMAN STX 21 MULTISPEED is designed for demanding users who require high splitting force and automatic speed adjustment.
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.

The MULTISPEED system enables automatic speed adjustment depending on the load:

  • At lower loads, the splitter works faster

  • At higher loads, it switches to slower splitting with greater power

Available in different drive versions:

  • C GP – PTO drive with cast iron pump (higher oil volume for faster performance)

  • EL – electric motor

  • C+EL – combined drive (PTO + electric)

Optionally, the XTREMSPEED system (for the EL version) can be installed, increasing splitting speed by up to 50%.

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, which ensures longer service life and improved splitting efficiency.
Safety solutions in compliance with EN standards guarantee safe use 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?"
