JAK-250B for excavators description

JAK-250B is our efficient and multi-purpose tree shear that is best suited for use with medium size excavators. The power of this popular tree shear is superior in its size range, and it is versatile for clearing small twigs and felling even larger trees.

The structure with two cylinders cuts the trees efficiently and precisely up to a thickness of 25 cm (9,8 in). The jaws and high profile of the JAK-250B tree shear take a firm and unmistakable grip on the wood. With the JAK-250B’s wide 690 mm (27 in) opening, it is also easy to cut several trees at once.

The firmly pressed wood is cut precisely and neatly thanks to a cutting blade shaped for the purpose, after which the wood material firmly attached to the grapple can be lifted to the desired location. If necessary, the cutting blade can be removed, in which case the tree shear acts as a wood grapple.

JAK-250B Tree shear accessories

The use of the tree shear can be diversified by equipping it with the following accessories:

 

Collector

Collector optimizes work efficiency and saves time. If the purpose of the tree shear is to clear smaller and more densely growing timber from the same area, this process can be made much more efficient and faster thanks to this collector.

The collector makes clearing easy and fast as the same area can be handled with less effort. With the help of a collector, the tree shear can collect several trees growing separately in the same bundle.

 

Tilter

Tilter brings more agility, efficiency and new entry angles to the tree shear when working with an excavator on clearing. With the help of the tilter, the tree shear can be turned up to 45° in both directions, so that its controllability reaches the highest level even in more challenging situations. In this case, clearing work with an excavator is more successful, as it allows easier access to difficult sites.

Felling support

A separate felling support attached to the tree shear makes wood control easier and safer. Optional felling support raises the height of the tree shear impact plate to ensure firm control of the wood. In this way, the felling support ensures solid control of the wood.

Quick valve

Quick valve improves the working speed of the tree shear. It allows faster movement of the unloaded gripping phase. The operation of the Quick valve is based on changing the oil flow when rapid traverse is more important than maximum force.
