JAK-METALLI OY

Description

The JAK-250R is an efficient and versatile tree shear model designed for use on excavators weighing 5-12 tons. The power of the JAK-250R is superior in its size class, and it is versatile for clearing small twigs and felling even larger trees. By changing the adapter to be attached to the back of the grapple, it is also possible to harness the JAK-250R for use in loaders and telehandlers.

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-250R tree shear take a firm and unmistakable grip on the wood. With the JAK-250R’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.

For B and R-series JAK Tree Shears

The Collector increases the productivity of the tree shear significantly. With the help of the collector, unnecessary movement is eliminated, and with this, speed and efficiency increase considerably.

Rotator and Rotary Manifold

For R-series JAK tree shears

The rotator and rotary manifold enable the JAK Tree shear to rotate endlessly in both directions.

Tilter

For Excavator JAK tree shears

Tilter brings more agility, efficiency, and new working angles to the use of the JAK tree shear when working with an excavator.

Electrically operated 6/2-directional valve E6212

For JAK-250B, JAK-250R and JAK-220C Tree Shears

By using an electrically operated 6/2-directional valve, you can divide one hydraulic function into two when using a tree shear.

Cable Control

With electrically controlled 6/2-directional valves for hydraulic control

Cable control is used to control an electrically operated 6/2 directional valve to move functions to different hydraulic lines.

Radio Control

For wireless control of hydraulics with electrically operated 6/2 directional valves

With radio control, it’s easy to control an electrically operated 6/2 directional valve to move functions to different hydraulic lines.
