TMK 400 – Tree shear for excavators

Thanks to its user-oriented design and top-quality materials, the TMK 400 is built to withstand demanding conditions. It is the largest machine in our range, and was originally developed for forestry work in Central Europe, where the trees are bigger and harder than in Finland. The TMK 400 is powered by cylinders specially designed for it, enabling the shear to easily cut trees up to 400 mm in diameter.

WHY CHOOSE THE TMK 400?

The TMK 400 shear can open to a width of up to 1,070 mm. The strong capsular structure of the TMK 400 can withstand the twisting force of even the largest trunks, while keeping the weight of the shear below 560 kg. Thanks to its relatively light weight, the TMK 400 is excellent for clearing both smaller brushwood and larger sawlogs. The 15 mm blade of the shear is made of extremely durable Hardox 500 steel. The recommended working pressure of the TMK 400 is 220–320 bar, depending on the cylinder.

The TMK 400 is best suited for excavators of between 10 and 30 tonnes. With the TMK 400, you can also use your existing machinery during the winter, when it may be difficult to find other excavator work. If you are considering energy wood contracting, for example, the TMK 400 will enable you to keep the start-up costs relatively low.

We are happy to help you use your machinery as productively as possible, regardless of the season. Contact us for more details!
