The conveyer-belt method is being more widely introduced into the timber
industry ana applied to all the steps of the production process, whereas formerly
it was employad in the initial stages only (frog,the felling of trees to their
loading on the railroad). Formerly, interruptions between operations used to
extend over 2 or 3 days. Stocks would accumulate and the principle of merchaniza-
tion was ignored. However, in spite of the shortcomings, the first steps wee
significant, and shoved that the timber industry and its personnel .sere ready to
change over to an advanced method of production. Innovators and Laureates of
the Stalin Prize, such as H. N. Krivtpov, A. P. Gotchiev, S. U. Luferenko, and
S. P. Nsekov" covtribui d to the success of the new method.
The author worked out a continuous technological process for the Balakhoninskiy
Timber Center of the Gor'kles and, thereby, the latter more than doubled its labor
productivity during the first quarter of this year.
One of the main characteristics of the new technique is the removal of the
timber in Ito state of flitch, with the sorting performed at,the lover piling
area. Thanks to this method, delays and accumulations due to bucking, sorting,
and stacking at the upper piling areas have been eliminated.
By way of experiment, the Central Research Institute for Mechanization and
Power transferred to the conveyor-belt method the Talakirevskiy Timber Center
of the 4.leksandrovskiy i~xperinental Timber i'a agement: ne experience gained
by the latter may be instructive:
The raw material base has the following characteristics: an available
timber reserve of 580,000 cubic meters, belonging to stock type lYeB40; an
annual timber release capacity of 50,000 cubic meters; an average grading of
1.2; a xenerve per heeta-^e of 215 cubic meters of available timber; an average
plant diameter of 25 centimeters; and an average flitch volume of 0.47 cubic
meters. It has a :iarrov-gaugc railroad.

Formerly, all logging at this timber point was done by hand. In the first
quarter of 1949, manual logging was 35 percent and skidding, 58 percent; the
wide-gauge railroad) were performed by hand.
The timber is skidded by means of KT-12 tractors over a distance of
500 - 600 meters, and by three-drum winches over 250 meters. The width of
piling area points have been eliminated. Instead, a very simple platform,
25 - 30 meters long, is constructed and beams are placed across it at a
distance of a quarter of its length from each end. It is recommended that

platform and along the railroad to facilitate the loading of the flitch.
In tractor skidding, the flitch is delivered to the platform from both
ends. In skidding by winch, the flitch is delivered to two platforms, one
on each side of the mast.
To remove the timber as flitch, loading has been mechanized by means
of the TL-1 winch. A jib in the form of an "A" is placed against the platform,
cr two simple jibs, 8 meters high, at a distance of 10 meters from one another.
The jibe are somewhat inclined toward the railroad so that their tops over-
hang the rolling stock.
The traction power of the TL-1 (one meter) is insufficient for lifting
large flitch; there.'ore, a mobile pule which makes the loading operation
calm and safe, is used.
Loading of flitch 0.30 and 0.35 cubic meters in size with an A-shaped
jib i.r+ done at a rate of 100 cubic meters per shift. The brigades consict
of three men: a jib operator and two loaders.
Narrow-gauged platforms were successfully utilized in the haulage of
flitch at the Balakirevskiy and Balakhoninskiy Timber Centers. By coupling
two such platforms, 16 - 17 cubic meters were loaded at the former point,
and 22 - 23 cubic meters, or 18 tons, of oak timber at the latter. The tare
coefficient was 0.52 in the case of the former and 0.39 for the latter.
The haulage of flitch was performed without complications. The loads
moved at the same speed as unsectioned timber.

simple stacking area, becomes a basic production point for finished products.
It m'ct have mechanized equipment for unloading flitch from rolling stock,
sorting, transport of assorted wood, as well as roads leading to the timber
Unloading is carried out by means of a mechanized log dumper consist-
ing of two masts, 8 meters high, from which a five-fold pulley is suspended.
To operate the log dumper, two drums are used, with cables of about equal
speed.
The unloading of platforms and all necessary operations (coupling of
car loads, shifting the platforms, etc.) takes 8 - 10 minutes, irrespective
of the size of the load. In the Balakhoninskiy Timber Management the
operation of removing processed timber by the new method reached 95 percent,
whereas the old method yielded only 70 - 75 percent in the past.
sorted on the platform are immediately dumped into the roller from which
they are later thrown off and placed into stacks.
Round timber requiring no processing is stacked by means of loading
=chiit nzztmhlit- ftt- rrtntf, rTr Fahr_1-3 '+"I,
logs over a distance of 70 - 80 meters.
Timber which must be processed (mine supports, etc.) as soon as it
reaches the stock is worked by means of a balance saw and a chain chopper.
Timber which is more than 2 meters long is loaded at the Balakirevskiy
center by means of two steam cranes; and short pieces, by means of a battery
transporter which piles it over a distance: cf 40 meters.
T.i: technique described above brings complete mechanization to heavy,
labor--_ onswing operations and yields higher labor productivity. It has
considerably reduced the timber production period, so that the time between
felling and delivery to the consumer amounts to only 24 hours. It also
allows for increased capital turnover. Finally, this method is based on the
use of series produced equipment which is already available, and may be employed
in most of the timber enterprises.
At the Balskirevskiy center, where the dicotyledonous type of tree pre-
vails, and consequently there are short timber assortments (common logs and
wood), the volume of work connecl.ed with flitch sectioning, sorting and stacking
at the lower piling area, is greater then in the processing of coniferous
timber. But even here, labor productivity has doubled through the new method
and in the third quarter has yielded 1.79 cubic meters per worker per day, as
against t2le previous 0.79 cubic meters.
The production process extends over 9 hours and 1s distributed as follows:
felling and lying time at the clearing, 4, hours; haulage over 600 meters, 0.5;
loading and train dispatch, 2; haulage over-the narrow-gauge road, 0.7; unloading
p:-at the lower piling area, 0.2; cutting the flitch into sections, 0.4; sorting,
0.2; and stacking - 1 hour.

Electric power, a particularly important element in this mechanized
process, vas supplied at the Balakirevskiy Center by the following types of
mobile stations: PES-12, TsNIINE-8, PES-60, PPS-CFO, and PES-50.
There remains the problem of applying this method in enterprises
which are at present hauling timber by truck or tractor and where the timber
transport roads adjoin rivers.
