Full gasification of the entire territory of Russia has not yet arrived. Therefore, a significant part of the inhabitants of the country, which has a rather harsh climate, has to heat their houses with old-fashioned wood.

The problem is that daily exercises with a cleaver or an ax do not cause much enthusiasm among Russians. Therefore, more and more often, homemade and “factory” wood splitters appear in the economy of modern owners, which greatly simplify the preparation for the heating season, since they are able to harvest a large amount of kiln material in a short time. .

The design and principle of operation of such devices, which are manual, mechanical and hydraulic, can vary significantly. However, the scheme of work is completely the same:

  • a wooden block in automatic or manual mode is placed in the feed chute between the knives and the mobile piston;
  • the piston pushes the piece on the knives which divide it into several logs.

Let’s leave out the manual and hydraulic version, because in everyday life most often a mechanical design with an electric or gasoline engine is used, which has certain requirements for power and the number of revolutions at the exit.

The thing is that a low-power device simply cannot cope with cutting firewood, especially hardwood and rough wood.

Therefore, when buying a factory device or assembling a homemade product, you should pay special attention to the motor power of at least 2.2 kW.

The dependence here is as follows – the higher the engine power, the higher the working pressure (measured in tons), which allows the device to split the most “complex” logs. In practice, it looks like this:

  1. When working with poplar, aspen and other “soft” wood species, a wood splitter with a working pressure of up to 5 tons will suffice.
  2. A similar parameter for units capable of splitting oak, pear and other hard wood blanks into firewood should be 5-7 tons.
  3. Damp wood and especially hard stumps can only be handled by installations with a working pressure of more than 7 tons.

The second important characteristic when choosing a wood splitting unit is the engine speed, which should be between 300 and 1000 rpm. Therefore, high-speed motors of such devices are necessarily equipped with reduction gears.

It remains to determine the type of engine. Electric motors are more suitable for fixed installations in everyday life (220V) and in production (380V). The petrol version is better suited to a mobile installation, as it has a longer range.
