Excavators 5-12 Tn (11000-26455 lbs)
The JAK-250B GEN4 is a fast, compact and powerful tree shear designed for use with excavators weighing 5-12 tons. The optional eBoost hydraulic system increases the speed of the tree shear by up to 100% without reducing power.
Thanks to the updated base machine, the number of accessories available has increased significantly. The design-protected structure with two jaws guarantees a solid and secure grip on the tree trunk. With the help of the tree shear, tree clearing goes smoothly up to 250 mm thick tree trunks. Thanks to the removable blade, you can also use the JAK-250B GEN4 tree shear as a regular timber grapple.
In manufacturing, we use Hardox® wearing steel, which guarantees durability and reliability in all situations and conditions. Domesticity and high-quality materials are the basis of the JAK-250B GEN4 tree shear.
