TRUSTS REPORT ON WINCH SKIDDING
Two skidding winches were placed Into operation in Tsinglokskiy Timber
Center, Volrhak Timber Management, Mariles Trust (K. D. Doroshevekiy,?chief
engineer) in April 1949. In May, four more skidding winches were installed
within the Volahek Timber Management..
At the Tsinglokskiy Timber Center, logs are skidded by winches to a nar-
row-gauge railroad 700 meters 1-mg, which connects with a wide-gauge railroad.
Horses are used for motive power on the narrow-gauge railroad line. The winches
are powered by a PSB-60 mobile electric power plant.
Trees at the timber center are pine and some spruce and birch. They grow
on slightly swampy soil. Resourceo amount to 120 - 150 cubic meters per hectare.
The center's continuous method brigade, which performs the cycle of oper-
ations from felling to loading onto the wide-gauge railroad, consists of 45 - 50
men. After introduction of winch skidding, brigade productivity per man per
day rose within a month from 1 - 1.2 cubic meters to 2 - 2.5 cubic meters of
timber. The amount of skiddL'g performed by each winch working within a radius
of 250 meters reached 42.9 cubic meters per day within a month after installation.
Within the aoatrcmales Trust, winch skidding averaged 43 cubic meters of
timber per winch per day during the first quarter 1949.
In Novgorodleo Trust, winch skidding averaged 32 cubic meters per winch
per day in the first quarter 1949.
In Timiryaaevakiy Timber Management, Towles Trust, average output per winch
per day averages 40 - 50 cubic meters.
In Novsibles Trust, winch skidding was inaugurated ~n dune 1949 at the
Nechunayevskiy Model 1xperimantal Timber Management of the trust.

Winches had been delivered to Kotlasles, Vologdoles, Eirlos, and Molotov-
bumlee trusts by June 1949, but were not yet in use as of that date.
The Sonskiy Timber Meuagtment has been successfully using a single-drum
winch for loading logs auto normal-gauge railroad cars. For this purpose, a
TL-1 electric winch with a load capacity of one ton, powered by a "Ural" F-42-4
motor with a capacity of 5.8 kilowatts, is used.
The winch is mounted on a 4.5-meter-high platform resting on four piles
driven into the ground. A booth, 2 by 3 meters, is provided on the platform
for housing the winch and sheltering its operator while he operates the jib
during loading operations.
Bleotric poorer is provided by a PM-50 mobile electric power plant. When
the PSS-50 powers two winches simultaneously, the peak load on it reaches 60 . 70
amperes at 380 volts.
A crew of four men is needed to load loge by this method: the winch opera-
tor, two men who hook the loge to the jib, and one man who arranges them on the
railroad car.
