MACHINE PARTS HAVE POOR RESISTANCE TO WEAR -- Moscow, Vechernyaya Moskva,
3 Mar 51
The Moscow Rostokinskiy Plant has established a special section for the as-
sembly of concrete pumps. These are new, heavy-duty machines, which can move 25
cubic meters of concrete per hour a distance of 300 meters horizontally, and 40
meters vertically.
Since last year the plant has put out 22 concrete pumps. The first models
were used with success in work on high buildings in Moscow. Now they are at
work on the construction site of the Volga-Don canal, where engineers are giving
good reports on them, stating that one pump replaces the work of 100 men.
The All-Union Scientific Research Institute for Construction- and Road-Ma-
chine Building designed the new machine, but unfortunately, When it. was trans-
ferred from the drawing boards to the assembly line-the institute lost interest
in it, and failed to follow it through the production stage.
It is now apparent that certain of the machine's parts are not sufficiently
resistant to wear. The cylinder sleeves, for example, had to be replaced after
the pumps had moved only several hundred cubic meters of concrete. Specialists
of the plant managed to develop a sleeve of specially heat-treated iron, which
proved to be ten times as durable as sleeves of the first type; but even this
improvement fell short of requirements, and construction workers are calling for
a sleeve of still higher durability. To answer this demand is not easy for a small
plant which has neither a laboratory;, nor the outside assistance of trained sci-
entists.
The plant gets parts for the pumps from several enterprises. Formerly, parts
came more or less regularly from the Kostroma Rabochiy Metallist Plant. Now they
come from the Kovrov Excavator Plant.

Unfortunately, flaws are all too frequently found in the parts received
from the Kovrov Plant. They also have excessive allowances, which means"that
there is more machining to be done on them. Furthermore, the Kovrov Plant con-
sistently holds up deliveries of its castings.
The Main Administration of Construction Machinery and the Ministry of Con-
struction- and Road-Machine Building should take steps to help the Rostokinskiy
Plant out of its dilemma. Specifically, they should see to it that the Kovrov
Plant improves the quality of its castings and delivers them on time.
The Rostokinskiy Plant is able to supply the Volga-Don construction project
with only one fourth the large number of concrete pumps which it has asked for.
The capacity of this plant is not great, yet it is assembling a great number of
other agg:?egates for the new construction projects.
The construction workers have proposed that concrete pumps of double the
capacity of existing models be made, so that fewer machines would be needed on
the scene of operations. The plant received this suggestion with enthusiasm,
and has begun work on two designs for such machines. One of these machines
will be a twin-body model mounted on a single frame; the other will have units
and parts of the same dimensions as the present pump, but the speed of the work-
ing cycle will be doubled.
There are, however, a great many technical and scientific problems to be
...au-uu..cea For the l ?nt

are having difficulty in determining the load under which the elements of the
machines will have to operate. If they are to increase the productivity of
pumps from 20-25 cubic meters per hour to 40 cubic meters per hour, they will
need outside help from scientists.- They will also need help in developing
better methods of inspecting welded seams and steel and iron parts, as well as
in the above-mentioned development of more durable cylinder sleeves.
It is assumed that the Advisory Bureau, and the Committee for Assisting
the Great Construction Projects, both of which belong to the All-Union Sci-
entific Engineering-Technical Society for Machine Building, will soon render
the Rostokinskiy Plant the aid it needs.
The Moscow Mashinostroitel' Plant fulfilled the 1950 plan ahead of time
and earned the Stakhanovite rating for 5 of its shops, 15 sections, 2 divi-
sions, and 39 brigades,
The plant is now series-producing special cranes, designed for use in re-
pairing steam locomotives. Two of these cranes were recently sent to Kharkov.
Truck cranes of 3-tca lifting capacity produced at the plant are now at work
at railroad stations, sidings, warehouses, and bases all over the country:
The plant brigade which tests the new excavators is-fulfilling its job 300
percent.
PORTAL CRANES HANDLE STRUCTURAL STEEL -- Moscow, Mekhanizatsiya Stroitel'stva,
Mar 51
The Promstal'montazh Lfndustrial Steel-Structure Assembly?7 Office has de-
signed three types of portal cranes for handling structural steel at storage
yards. At present, 20 of these cranes are being utilized by the Main Administra-
tion for Production and Assembly of Steel Structures of the Ministry of Construc-
tion of Heavy-Industry Enterprises.

The cranes, designated the PK-15, PK-20, and PK-50, are similar in basic de-
sign, and are equipped with series-produced electric winches of ordinary type such
as the EL-5 and the EL-3.
It has been found that the use of these gantry cranes instead of railroad
cranes is saving about 25 rubles per ton of structural steel..

MIXER CAN BE PUT UP, TARN DOWN -- Moscow, i+ie'xhanizaisiya Jt-olUG~
In the beginning of 1950, the Kremenchug Road-Machine Plant imeni Stalin put
out the new D-225 asphalt-concrete mixer. It has a productivity of 8-10 tons per
hour and weighs 16,000 kilograms. Built according to specifications of the All-
Union Scientific Research Institute for Construction and Road-Machine Building,
the D-225 is suitable for use in rayon and oblast road building and maintenance.
Testing showed it to be entirely satisfactory.
The D-225 is mounted on a steel structure which can be readily assembled
and taken down. Sand and gravel are fed up to the dryer, then screened and mixed
in measured portions with bitumen. Trucks can be driven underneath the supporting
structure to carry off the finished product.
Another, larger asphalt-concrete mixer, the D-152 is now series produced by
the Ministry of Construction- and Road-Machine Building. It has a productivity of
25-30 tons per hour.
BIRLD ELEVATORS FOR NEW UNIVERSITY -- Moscow, Vechernyaya Moskva, 20. Dec 50
The Moscow Pod'yemnik Plant has completed four-high"speed passenger elevators
for the MoscoW State' University. Nine more of these elevators are being assembled
in the plant.
ELEVATOR CAR ON DISPLAY -- Moscow, Moskovskaya Pravda, 31 Jan 51
The Ministry of Heavy-Machine Building is exhibiting the car of a high-speed
elevator, built by one of the ministry's plants for a Moscow building.
The car, which carries over 20 passengers, is built of heavy steel plate.
The mere push of a button will open the door. Plants of the ministry will pro-
duce 140 of these elevators in 1951. They will go-to the new buildipg going up
on Smolenskaya Ploshchad, to the building on Kotel'nicheskaya >Habere.bneya, and
to a new building for the Moscow State University.

Three types of elevators have been built so far: one, for service to the
first few floors has a speed of 1.5 meters per second; the second type has a
speed of 2.5 meters per second; the third travels at 3.5 meters per second.
Freight elevators, and small service elevators of 250-kilogram capacity will
also be supplied for the buildings.
Engineers of the electrical industry have designed a number of electri-
cal units for the elevators.
WILL TAKE ON NEW PRODUCTION -- Moscow, Moskovskiy Komsomolets, 25 Feb 51
The Krasnogorsy Pavshinskiy Machinery Plant has established production of
a number of complex machines for the construction industry.
During 1950, the plant put out over 50 machines for the manufacture of
cement, brick, glass, and other materials. Of special importance are the cen-
trifugal pipe-casting machine and the electric spreader which the plant is
now producing.
This year, the plant will begin production of an unloading and piling ma-
chine designed for use at plants producing dry plaster, and of molds for mak-
ing fancy glass articles.
