METHOD OF DEVELOPMENT OF FOREST AREAS OF OIL-AND-GAS PIPELINE ROUTES AND POWER TRANSMISSION LINES Russian patent published in 2013 - IPC A01G23/00 

FIELD: agriculture.

SUBSTANCE: method comprises the operations: felling of trees using chainsaw in the direction from the developed part of the route, limbing, tree length bucking and laying branches on the route of the future road using delimber-crosscutter, loading and transportation of assortments by lumber truck with a manipulator. The lumber truck enters, for example, reversing on the strip of packed branches at a distance equal to the length of the pack collecting. On its way back the lumber truck, stopping at the working positions, loads the assortments located on the left and right from the strip to collect the full-car-load pack, after which it transports the loaded assortments. Tree felling on the future road route is performed in the direction parallel to its axis. Limbing and tree length bucking by delimber-crosscutter is carried out in the normal mode with the laying of the obtained assortment on the left or right near the future route. Felling a tree which is located on the right and near the future road route is carried at an angle of 0 to 25 degrees to the axis of the future road. Limbing and tree length bucking by delimber-crosscutter is carried out in the normal mode with the laying of the obtained assortment on the left. Felling a tree which is located on the right in the far distance from the future road route is carried at an angle of 25 to 45 degrees to this road. Limbing and tree length bucking by delimber-crosscutter is carried out by capturing the vertex part of the tree by clamp hook, hauling in the raised position by a distance that provides gripping by the manipulator of the root part of the tree, with the subsequent laying on delimbing and crosscutting table. The resulting assortments are placed near the future route on the right. Felling a tree which is located near and on the left of the future road route is carried out at an angle from 0 to 35 degrees. Limbing and tree length bucking by delimber-crosscutter is carried out in the normal mode with the laying of the obtained assortment on the left. Felling a tree which is located on the left in the far distance from the future road route is carried out at an angle of 35 to 60 degrees. Limbing and tree length bucking by delimber-crosscutter is carried out by entering reversing to the fallen tree, capturing the vertex part of the tree by clamp hook, hauling in the raised position by a distance that provides gripping by the manipulator of the root part of the tree, with the subsequent laying on delimbing and crosscutting table. The obtained assortments are placed near the future route on the left.

EFFECT: method provides reduction of energy consumption and the impact of technology on the forest environment.
