METHOD OF DRUM LOGGING AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2017 - IPC A01G23/00 

FIELD: wood processing industry.

SUBSTANCE: invention relates to the tree or stick bundle assembling. The method includes the installation of a machine equipped with a winch and an inhaul rope with chokers at the working position - at the main longway, disinhibition of the winch, movement by the choker of the end of the inhaul rope with the chokers to the to the tree or stick bundle assembling place, their chokering, forming the bundle by including the winch on the interference of the inhaul rope and subsequent skidding of the bundle to the place of further processing. During the first movement to the apiary, the chokerman, with the inhaul rope, moves the additional winch of the device to pull the inhaul rope with the chokers to harvested trees or sticks, fixes it to a fixed support - a tree or a stump, and connects the free rope end of the additional winch to the end of the inhaul rope. During the bundle skidding, the rope of the additional winch is unwound. The chekers are removed by the operator, after which the chokerman turns on an additional winch and returns the inhaul rope with the chokers to the apiary to collect another bundle of trees or sticks. The device has an additional winch, the housing of which is provided with a binding kit for fixing it to a fixed support - a tree or a stump. One end of the rope of the additional winch is rigidly fixed to the drum, and the other has an interwoven ring with which it is connected to the movable end of the inhaul rope. The ring is mounted on the inhaul rope first, and then the chokers are inserted and then the locking half ring.

EFFECT: laboriousness is reduced and the time of the skidding process is reduced by providing the chokers to the fallen trees or sticks with the help of an additional winch.
