IE PICIENCY SLOWS EXCAVATOR PRODUCTION
NEW EXCAVATOR HAS ADJUSTABLE TREAD -- Moscow, Mekhanizatsiya Stroitel'stva,
Oct 50
The Krasnyy Ekskavator Plant has put out a new multiple-bucket transverse
excavator, the EM-502. The Leningrad Affiliate of the All-Union Scientific
Research Institute for Construction- and Road-Machine Building helped with
the machine's design, the outstanding feature of which is its mounting_on
crawlers of adjustable span, The body rides directly on the main crawler, while
a secondary, lighter crawler is attached to the end of a telescoping tube,
like an outrigger. Thus, in digging an irrigation canal.or ditch, for which
the machine was primarily designed, the two crawlers can ride along opposite
sides of the trench, adjusted to its width, while the bucket arm is. lowered
between them to dig along the wall. It is also possible to have both crawlers
on the same side of the ditch, the secondary one serving as 'a counterweight
t; the bucket arm.. A conveyer arm extends to the side'oppusite the' bucket arm,
taking away the earth,'and depositing it on the bank.
The EM-502 weighs 18,930 kilograms. It is powered by a 52-horsepower
STZ-NATI motor and has four forward speeds,. from 62 to 411 meters per hour.
The crawlers may be adjusted to spans l;700-7;000 millimeters'broad. Actual
productivity, in digging new canals, amounted to 25.6-38.2 cubic meters per
hour; for work in existing canals, it amounted to 56.0-68.0 cubic meters per
hour.
On the basis of tests, the machine has been recommended for series pro-
duction.
AUGER TO HELP PIPE-LAYING -- Moscow, Mekhan3.catsiya Stroitel'stva, Oct 50
The Zaporozhstroy Trust has developed a new horizontal earth auger, the
GBM-2, designed for cutting under main pipe lines, streetcar or railroad
tracks, and other obstructions, so that pipes can be'put.through.

CANAL DIGGERS TO BE SERIES PRODUCED -- Moscow, Mekhanizatsiya Stroitel'stva,
Oct 50
During May and June 1950 there was an interdepartmental test of the 104=800
and the KM-1,000-A towed plow-type canal diggers, designed by the Institute for
Mechanization of Agriculture, Academy of Sciences Belorussian SSR, and built
at the Road Machinery Plant imeni Stalin.
The KM-800 is for digging small canals in marshy ground and ground
containing minerals, free of tree roots and rocks. The KM-1,000-A is de-
signed for digging canals in peat fields. Both machines dig a finished canal
in one pass. Their basic units are similar, differing only in the size of
the digging elements and the number of wheels: two for the KM-1,000-A, three
for the KM-800. Both machines are designed to be towed by a pair of S-8o
tractors.

NEW EXCAVATOR TRIED OUT IN CANAL -- Moscow, Mekhanizatsiya Stroitel'stva,
Nov 50
The Kiev KrasnyY Ekekavator Plant has built and tested a new multiple-
bucket transverse excavator, the EM-301. Technical plans for the machine
came from the Leningrad Affiliate of the All-Union Scientific Research
Institute of Construction- and Road-Machine Building.
The machine moves along-on rails, two long booms projecting out to
either side. One of the booms is equipped with an endless chain of buckets:,
It can be raised or lowered, to suit the angle of the terrain, and digs
away transverse strips as the machine moves forward. The
boom, t depositedd
onto a conveyer belt, which runs out along. the opposite onto a pile or into a truck.

The bucket boom ie 9 meters long, the conveyer arm 10-12 meters long. All
operations are powered by electric motors. A drum mounted at the rear winds

POOR MANAGEMENT COSTS PLANT TIME, MATERIAL -- Tbilisi, Zarya Vostoka, 14 Sep 50
In the machine section of the assembly shop at the Tashkent Excavator
Plant everything runs behind schedule during the first 10 days of each month.
Billets and semifinished parts are supplied late, many workers are idle. Tools
are not available to machinists; drillers and planers, having nothing else to
do, carry out chips. Things are even worse during these 10 days in the assembly
section, where workers have nothing to assemble.
Work is plaried no better in the primary production shops -- the foundry,
the forge shop, and the machine shop. A first glance at the plans of the foundry
and forge shop gives the impression that everything is in order; even production
rates and group output systems are indicated on the chart. There is a period of
several days, however, during which the chart is run through with red marks denot-
ing nonfulfillment.
Rejects in the foundry amount to 15-20 percent; for some types of gears the
figure reaches.50-60 percent. Molding and pouring are done by hand, even though
the shop has been equipped with the latest molding machines. Because of the in-
efficiency and dilatoriness of the directors, the machines are not being properly
exploited, while the chief metallurgist and the plant directors fail to reprimand
the shop directors in spite of the several hundred thousand rubles the foundry
has lost from rejects during the last month.
The machine shop gets only enough parts from the foundry, without a single
extra billet, so that a al}ortage is created when flaws are discovered while the
parts are being machined. Finally, there is a stoppage in the assembly shop.

Because proper accounting is not maintained, many parts are lost in transit
from the forge shop to the machine shop. Many billets lie in disorder about the
machine shop, with workers taking them as they need them. Listing and account-
ing of rejects is confined chiefly to heavy parts, while the smaller rejects dis-
appear without a trace, along with the labor of the forger, and the metal. The
situation has prompted the director of supply, Bedrikov, to remark that the metal
vanishes, and that there is nothing to show' for it.
Once, the forge shop stopped work on some already-heated bolts, to meet a
deadline on three levers. For the manufacture of several dozen bolts or nuts, it
has often been necessary to call out the day-shift workers at night, to start up
the furnace and heat 3-5 kilograms of metal, Several times more resources are ex-
pended. than provided for in the plan.
The progress of the plant during August, for which it pledged production of
two above-plan excavators, is typical. Only one third of the plan was fulfilled
at the end of 20 days, when the shop suddenly was thrown into violent activity,
with -)nly 10 days left to meet the plan, It was found that there were no cotter
pins, so the director of the planning section, Lundin, ordered that some be made
of wire. An entire day was spent in finding suitable wire. Then the cry arose
that there were no bolts, that there were no gears, that a bushing was faulty.
The director of the planning section then ordered that the spare parts
boxes be opened. Imagine an excavator without spare parts!
The work became tense, and the resources of all the other shops were drawn
upon. Repair of equipment was halted in the machine repair and electrical shops;
welders and mechanics were taken out of the forge shop and foundry.
At the end of the month the pledge was met. But the excavators, lacking
spare parts, cannot be sent to the consignees.
One Stakhanovite worker declares that the assembly section could assemble
twice as many machines if it could only get its parts on time. It behooves the
plant director, Binkenshtat, to share this opinion, and to take measures to im-
prove planning, eliminate rejects, and put new equipment into operation more
promptly.
