Felling grapple with a chainsaw and a knife for cranes

Knife ⌀ 30 cm

Saw ⌀ 40 cm


A multifunctional grapple for easy and flexible use

For the harvesting operations where different species of hardwood and softwood, different diameters and wood qualities are mixed, the Biojack Combi felling grapple combines the two cutting tools: the chainsaw and the knife. The most flexible and adaptable solution to any situation, and the alternative to investing in several devices only adapted to a specific diameter.

The chainsaw can cut solid wood, medium and large diameters, hard woods, large branches in urban felling, while the knife is more suitable for coppice, brush, energy wood, all situations where a saw chain can jump, get stuck, or touch stones. The knife is much faster and requires very little maintenance.

The Combi is the right solution for the maintenance of mixed forests, riverbanks, roadsides, railways, power lines, parks, but also in thinning work, in mountainous terrain and in tree care.

The grapple is fully functional for handling and loading wood. During the loading cycle, the knife stays inside its casing.

This felling grapple also features the delimbing tines as standard, to remove quickly the branches on the tree trunk.

  • Flexible work cycle
  • Pressure and return hose, leakage oil hose, electric wire or wireless control for the saw
  • Saw chain lubrication with chainsaw oil
