Sawing and splitting machines

for big challenges

Are you looking for a new solution for the production of log splitting in the forest industry? S&Ü is known for its large sawing and splitting machines with a high degree of automation. We are your partner for robust machines in the entire process chain for firewood preparation: from sawing and splitting, through drying, to professional packaging. We offer proven series products for which you can choose many individual extras and variants.

Innovative automatic interval splitting machines

With sophisticated splitting mechanisms, the automatic sawing and splitting machines process thick wood up to 800 mm into evenly sized logs. The special feature of our automatic firewood saws is that they do not press all the wood at once through a multipart splitting cross, but process it repeatedly with a large cross-cut blade as it is slowly pushed past. As a result, the innovative interval splitting machines use significantly less splitting pressure than conventional log splitters.
For log feeding of logs up to 6000 mm long, S&Ü relies on a pusher system instead of a conveyor belt. Automatic log length measurement helps you avoid offcuts.
The stationary automatic sawing and splitting machines for use in yards or halls are driven by electric motors. The mobile solutions, which chop your logs directly at the forest road, are driven by diesel engines.

Remote maintenance for mobile firewood machines

Mobile machines and plants are often used in remote locations. For this purpose, we use powerful operating devices and remote maintenance solutions that have to be particularly robust in the forestry industry. No matter where your plant is located: Via remote maintenance, our customer service quickly rectifies any faults.

Durable and powerful with low operating costs

We adapt the versatile automatic sawing and splitting machines optimally to your individual utilization challenges right from the construction stage. Due to their high quality, repairs are rarely necessary even at high production rates with high splitting speeds. You benefit from the long service life and low operating costs.

Processing of heavy timber

The ISSA 800 automatic sawing and splitting machine processes logs up to 800 mm in diameter. The much more compact ISSA 700 processes log diameters up to 700 mm into firewood.
For processing large log diameters in forestry operations, we offer long log splitters or large splitters that split log diameters up to 1000 mm, 1200 mm, or 1500 mm to a length of 3000 mm, for example.

With the ISSA 800 automatic sawing and splitting machine, you can split logs up to 80 cm in diameter into manageable logs in no time at all.

The mobile machine owes its name, automatic interval splitter, to its state-of-the-art splitting method: Contrary to conventional automatic splitting machines, the wood is processed at intervals by a large cross knife and thus cut successively into logs. This procedure allows a significantly lower splitting force of just 25 tonnes compared to other automatic sawing and splitting machines.
The ISSA 800 offers exceptional productivity when combined with the convenient log feed via push system, the easy-to-operate crane and the high-performance saw-bar.

The high degree of automation and intelligent monitoring via remote maintenance enables companies in the wood industry to achieve a considerable level of throughput.

The different designs – mobile or stationary – are individually engineered for each customer.

The latest storm inflicted considerable damage on forests and their owners across Europe. For the processing of large wood diameters we offer long log splitters / large splitters which split log diameters up to 1.00 m, 1.20 m or 1.50 m at a length of, e.g., 3 m. The drive and features are variable. Ideal for pre-splitting for chipper loading.

World record set with S&Ü automatic sawing and splitting machine

In the video you can see how our customer, the firewood manufacturer Chenuz bois de feu Sàrl, produced 793 ster (cubic meters) of wood splits within 24 hours and thus achieved a new wood splitting world record.
