Description

Equipped with the excavator adapter, the JAK-300R is a powerful tree shear designed for use in larger size excavators weighing over 12 tons (26455 lbs). By changing the adapter to be connected to the grapple, JAK-300R is also possible to harness for use in loaders and telehandlers, for example.

The jaws of the JAK-300R take an unfailing grip on the wood. With the wide opening of the grapple, several trees can also be cut at once, and the force of the grapple does not coagulate even with a large mass. Due to its large size, the JAK-300R easily cuts a tree’s diameter up to 30cm (11,8 in) thick. At the same time, it is also ideal for felling into smaller stands, as its handling is precise and effortless.

The wood that has been firmly pressed by the grapple is neatly cut thanks to the grapple cutting blade. If necessary, the cutting blade located below the JAK-300R can also be removed, in which case the energy grapple acts as a normal wood grapple.

JAK-300R excavator tree shear accessories

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

Rotator

The rotator improves the use and reach of the grapple, making wood handling easier. The rotator works, as its name implies, to allow the tree shear to rotate along the axis of the arm. This allows for a wide variety of working angles and makes clearing easier, especially when working in challenging terrain.

specifications:

  • Weight of the rotator: 139 kg (306 lbs)
  • Rotator mounting clip weight: 5 kg (11 lbs)

Rotary manifold

The rotary manifold to be installed in connection with the rotator allows the grapple to be rotated indefinitely in both directions. When the hydraulics associated with the use of the grapple jaws are controlled through the bushing, the user does not have to worry about the hydraulic hoses rotating inside the tree shear when rotating the grapple.

Specifications:

  • Rotary manifold + mounting clip weight: 11,5 kg (26,4 lbs)

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.

Saw

The saw brings efficiency to clearing work. With the help of a saw mounted on the place of the cutting blade, you can neatly cut even several trees at a time. The saw also allows thicker trees to be cut at once, which not be possible with a cutting blade alone.

Felling support

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.

Specifications:

  • Weight of the felling support: 33 kg (72,7 lbs)

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.

Foot

A foot is an accessory that is installed below the rear of the tree shear. The foot is used as a support point if, for example, the excavator needs to be turned to the ground by pressing the boom of the excavator

Specifications:

  • Weight of the foot: 20 kg (44 lbs)
