To be honest, it has always been interesting why they leave half-finished after a horizontal cut with wedge inserts, and do not finish sawing to the end, what is the meaning of this threshold
Using a mechanical felling wedge, the feller alone completely controls any tree being cut down and brings it down in the direction he needs. The load capacity of the mechanical felling wedge is 6 tons, the weight is 3.5 kg. The small size allows the use of the wedge in a limited space in the presence of nearby trees, dense undergrowth.
In winter, in conditions of heavily frozen wood, the hooks on the plane of the cheeks securely hold the wedge in the cut of the trunk, which makes winter logging stable, eliminating emergency situations.
The reliability of the device and its ease of use, which does not require special skills to work with itself, will allow lumberjacks to quickly master the directional felling of trees. In some cases, it will help to solve the personnel issue by attracting workers with little experience in felling trees.
The use of KVM provides additional opportunities for hauling trees.
In one shift, the tractor driver, on the MTZ-82, shoots out up to 50-60 trees, provided that the trees are felled along the hauling direction. If you fell trees in the direction of their slope, anywhere, the performance of the skidder drops by 2-3 times, plus the time spent on harvesting young trees broken during skidding.
