Logging Terms - L -
LANDING: Any place where logs
are laid after being yarded and before transport to the worksite.
LAY: Refers to either the position in which a felled
tree is lying or the intended falling place of a standing tree.
LEAD: Predetermined direction of falling the trees of
a particular strip or area in regard to the relation of the trees to one another
and their combined relationship to the surrounding terrain.
LEAD: The established direction in which all trees in
a quarter or strip are to be felled, usually governed by the terrain of the
area, or its general slope or skid road system.
LEAN: Refers to the directional tilt of a tree away
from its vertical position. Many times two lean forces may be in play in the
same tree. They are referred to as head lean and side lean. The lean, or leans,
of a tree can be easily established with the use of a plumb-bob or axe handle.
LEANER: A tree that leans excessively, not growing
straight.
LEG PROTECTOR: Ballistic nylon pad attached to one or
both pant legs to protect the leg from contact with the saw chain. It can be
attached to either the inside or outside of the pant leg.
LIFT TREE: An intermediate support for skylines.
LIGHTNING STRIKE: Tree that
has been struck by lightning.
LILY PAD: A thin slice of wood, sometimes taken off
the stump and used to cover the saw if it's to be left out.
LIMB LOCK: A series of cuts made on limbs to release
back or side pressure and create a stay in the limb that will prevent the limb
from either kicking back and striking the logger or pinching the saw.
LIMB LOCK: Limbing technique used to more safely
handle back pressure and sideways pressure on limbs in order to reduce the
liklihood of a limb under pressure kicking back and striking the logger's leg or
pinching the saw. Two bypassing cuts are made, one on the top side and one
on the bottom side of the limb (top and bottom refer to the top and bottom of
the limb as if the tree were standing up). The cut on the top of the limb
is made closer to the trunk of the tree and the cut on the bottom is made
further out on the limb. This creates a step in the limb which helps
prevent the limb from kicking out or back toward the logger.
LIMBING: To cut branches off felled trees.
LOADING BOOM: Any structure projecting from a pivot
point to guide a log when lifted.
LODGED TREE (Hung Tree): A tree leaning against
another tree or object which prevents it from falling to the ground.
LOG: A segment sawed or split from a felled tree, such
as, but not limited to, a section, bolt, or tree length.
LOG DUMP: A place where logs
are removed from transporting equipment. It may be either dry land or water,
parbuckled over a brow log or removed by machine.
LOGGING MACHINE: A machine used or intended for use to
yard, move, or handle logs, trees, chunks, trailers, and related materials or
equipment. This shall include self-loading log trucks only during the loading
and unloading process.
LOGGING OPERATIONS: Operations associated with felling
and moving trees and logs from the stump to the point of delivery, such as, but
not limited to, marking danger trees and trees/logs to be cut to length,
felling, limbing, bucking, debarking, chipping, yarding, loading, unloading,
storing, and transporting machines, equipment and personnel to, from and between
logging sites.
LOG STACKER: A mobile machine mounted on a wheeled or
tracked chassis, equipped with a frontally mounted grapple, tusk, or forklift
device, and employed in the loading, unloading, stacking or sorting of logs.
LONG-BUTT: After a tree is felled a section of the
butt-end may be sawn off because of rot.
LONG STICKS: An overlength log that creates a hazard
by exceeding the safe perimeters of the landing.
