Embodiment

[0034] Such as figure 1, 2 As shown, a method for expanding the logging area of ​​a cable skidding crane once installed includes the following steps:

[0035] Step 1, first, take the vertical ground projection of the load-carrying cable as the central axis 9, and set 20-meter boundary lines 8 and 10 at the widths of 20 meters on both sides of the central axis 9; then, collect the two 20-meter boundary lines 8 , wood within 10 range;

[0036] Step 2, after collecting the timber within the limited range of Step 1, look for a standing log or felling root 4 inside the 20-meter boundary line 8,10;

[0037] Step 3, a guide pulley 5 with a manual opening function is fixed on the standing tree or felling root 4 with a steel cable;

[0038] Step 4: Use the remote controller to start the dual interlocking brake in the sports car 1, brake the hoisting rope 3, release the brake on the load-bearing rope 2 at the same time, notify the winch operator to start the hoisting reel, pass the h...

Abstract

The invention discloses a method for expanding one-step installation yarding area of a cable yarding crane, and the method comprises the following steps: 1, taking a carrying cable vertical ground projection as an axis line for arrangement of 20 meters border lines respectively on 20 meters width positions of both sides of the axis line; 2, finding a standing tree or stump within the inner side of the 20 meters border lines; 3, arranging a guide pulley on the standing tree or stump; 4, adjusting a running car to a proper position; 5, drawing a hoisting rope to the position of the guide pulley on the standing tree or stump, manually opening a lock catch of the guide pulley, loading the hoisting rope into a pulley groove, locating a wood grasping hook on the end part of the hoisting rope on the outer side of the guide pulley, locking the lock catch, and beginning yarding working in the area beyond the20 meters border lines. Under the premise of being in compliance with the rules of safe operation, the method minimizes the dismounting times of the cable yarding crane, is time and labor saving, and can be promoted and applied in yarding working in the forest area.

Description

technical field [0001] The invention relates to a method for expanding the logging area of ​​a cable logging crane once installed, and belongs to the technical field of application of mechanical equipment in forest areas. Background technique [0002] In order to speed up the mechanization process of harvesting and transportation in southern forest areas of my country, a self-propelled all-terrain cable skidding crane with tower is more and more used in skidding operations in southern forest logging areas. The tower and winch system of the cable skidding crane are integrally installed on the wheeled chassis, and can be driven along the forest road under the traction of a small wheeled tractor for mobile operation. When faced with a predetermined felling area, the cable skidding crane can be moved and installed several times to implement block-by-block logging operations until it finally covers the entire logging area and completes all logging tasks in the logging area. The s...
