The Volgograd Steel Wire & Rope plant, our

manufacture since the Soviet Union times –now is

commercially viable goods, successfully
competitive with the leading European companies.
Cable design is the crucial element of bridge construction and
reconstruction especially for those water bridges (wet bridging) where
wave breake-through occurs during disastrous floods, as well as
hydroelectric units demolition.
When this happens, the most vulnerable are highlands.
Constructive improvements to prevent bridge destruction.
Volgograd branch of OAO Severstal Metiz/ Severstal Metiz Co. Inc. is the
first in the history of Russian cable industry to design the technology of
suspension cable manufacturing of any degree of compexity
The most common model of bridge
demolition I-beam constructions hold floating boughs, small logs of
wood and other rubbish. They block the water flow under
the bridge if flood occurs. Moreover, emerging dam
attracts next lots of small woods. The water pressure
becomes higher and higher, as a result a bridge knocks
down like a house of cards.
Widely spread is the
bridge design consisting
of several fixed piers and
bridge vaults. The
shortage of this design is
that it can not be used at
the water barriers where
the wave outbreaks
happen with significant
depth and current
speed. Shock wave
velocity completely
demolish the bridge or
causes severe damage, making it out of use.
This process is even more dangerous in highlands. Sharp downgrades of
mountain terrains determine (sudden) instant flood rise, up to 1,5-2,5 m and
higher within few hours. Simultaneously instant dumping of (overflow of
flood water) from tributaries located in the mountains into the river valley.
Totally in spring of 2011 3 thousand 29 residential areas, 315 railway
sections, 492 bridges (35 of them in the zone of excessive risk area) are
potentially flood exposed. This process is even more dangerous in
highlands. Sharp downgrades of mountain terrains determine (sudden)

Ministry of Regional Development of the Russian Federation
crutinized Your petition dated 10th of November, 2011 № 37-
89/HM on target program of scheduled replacement of bridge
crossings in flood- and mud torrent prone regions for the
suspended cable constructions and states upon the following:
Taking into consideration the urgent character of the issue,
described in your petition, the Ministry fully supports the concept
of the afore-mentioned target program and, whithin the scope of
its competence, is ready to examine the road maps prepared by
the concerned regional and federal bodies of executive
power of Russian Federation (regional governments, Ministry of
Economic Development, Ministry of Finance, Ministry of
Transport, Ministry of Emergency Situations).
Emercom of Russia scrutinized Your proposal on replacement of
bridge crossings in flood- and mud torrent prone regions of the
Russian Federation for the suspended cable bridges within the
frame of the federal target program and states upon the following:
In fact, a number of the Russian Federation regions’ bridge
crossings are prone to the threat of floods and mud torrents. Very
often beam bridges give favorable background for ice jams
facilitating potential emergency situations during the spring floods.
Suspended cable bridges availability will facilitate the vital activity
security in general and especially in mountain areas.
From our side Emercom has sent the letter of support of your
petition to the concerned federal bodies of executive power.
Signed by the Minister, Sergey Shogun
It is worth mentioning mud torrents as well. They are extremely dangerous not
only due to they destructive power but also for their unexpected occurrence.
Rainfalls in rock habitat very often doesn’t cover the foothills and mud flow
happens all of a sudden in residential areas. Due to the fast speed of mud
torrent the time when it starts in the mountains and when it reaches the foothill
counts for 20-30 minutes.
Mud torrents are spread in all mountainous regions of this country (currently
there are some 6000 records).
For this very reason the suspension/cable bridge is the most feasible for the
mountainous areas. Due to the following reasons:
Absence of buttress – the most vulnerable part of construction during the flood
– allows to avoid the risk of washing away the I-beam constructions.
Relevantly low metal-consumption – solid rocks allow not to use huge concrete
carcasses, consequently, essentially reduce the cost of the whole construction
itself.
Take a special note on cable roads. Construction of highly efficient cable
road is in hundreds times less expensive than a bridge construction.
Cableways are eco-friendly and exotic means of transportation.
Since the USSR times Volgograd plant of OAO Severstal-Metiz is the
only one within the whole CIS territory with machinery and technologies
available, capable to build any cableways.

the road sector of
industry where
cables are applied
Fixing up crash barriers with the steel wire
rope application
The main trend of the passive impact measures on
highways and roads is, as a rule, connected with the
selection and installation of various types of railings and
shields which due to the bending deflection or
reversible/elastic deformation of construction are able to
change the trajectory of hitting them vehicles, to absorb
the kinetic energy of the impact or to reduce this impact to
the minimum
Unlike the rigid road barriers cable railings are damping the
vehicle impact, saving lives of accident participants, minimizing
vehicles and road damage in a car reck. Cable guardrails save
the road space and make road maintanance easier, especially in
winter time.
Let’s start with the fact that it is more safe rather than any other type of
guardrails. Its application reduces the level of injuries, accident rate
and vehicle damage level.
Advantages of wire cable guardrails
Quick and simple assembling (installation) does not require heavy installation
machinery or specialized tools.
Relatively low maintenance and repair cost. The repair is quick, simple and
manual (manhandled) without any mechanical equipment application.
Wire cable guadrails, installed at the traffic dividing strip, are more cost-efficient
(economically viable) rather than two-fold road barrier. Also the application of
this particular construction can reduce the width of the dividing barrier due to its
small size
Thin cross-section/profile blocks the formation of snow piles/banks. This
is very relevant for this country.
Also wire cable guadrails are aesthetically pleasing at highways.
