  Concrete pylon - Biocrawler   (Site not responding. Last check: 2007-11-03)
Concrete pylons are manufactured as a rule in the concrete work and put up at the place of assembly.
Concrete pylons are used in Germany normally only for lines with operating voltages below 30kV.
In exceptional cases concrete pylons are used also for 110kV-lines, as well as for the public grid or for the railway traction current grid.

Burton and five co-workers had positioned the pipe against a concrete wall to support an electrically-powered hydraulic ram that was used to push the fan into position onto the shaft.
Evidence of concrete chipping was present by the location of marks in the wall where the supports were previously used to push the fan onto the shaft.
The bar stock used between the concrete wall and the pipe; the pipe, and the steel plate used to support the 10 ton ram, were all bent and deformed indicating that a large load was imposed during the fan installation attempts.

 Sydney Harbour Bridge - Wikipedia, the free encyclopedia
Although inserted into the designs for their aesthetic value, all four pylons have now been put to use: a museum and tourist centre with a lookout of the harbour is contained in the southeastern pylon.
The southwestern pylon is used by the New South Wales traffic authority as a base for their CCTV cameras overlooking the bridge and the roads around that area.
After the increase to $1, the concrete barrier on the Bridge separating the Bradfield Highway from the Cahill Expressway was increased in height, because of the large numbers of drivers crossing it illegally from lane 7 to 6, in order to avoid the toll.

 Cable-stayed bridges and more particularly to their pylons and stay cables - Patent 5197157
In such assemblies, for the sake of the mechanical strength of the pylon, the simplicity of manufacture and even for aesthetic reasons, the stay cables are grouped in pairs extending obliquely downwards from the same vertical section of the pylon, on each side thereof in the longitudinal direction of the bridge.
The zones in which their tensile forces are applied on the pylon are then offset transversely with respect to the longitudinal direction of the bridge, which leads to applying twisting torques on the pylons as well as to a questionable aesthetic appearance.
4, the whole of piece 5 is embedded in the concrete forming the pylon 1 and the different twisted strands are mounted and individually anchored after manufacture of the pylon.

 Cable Ready Maumee River crossing
High performance concrete mixes, new post-tensioning practice, alternative girder erection techniques, and the debut of an innovative cable cradle system for an architectural pylon combine for a spectacle unfolding along Interstate 280 in Toledo, Ohio.
Cast from high-strength concrete, the pylon will feature an endlessly changing array of colored lighting enclosed by glass — a signature product of a city known for companies like Libby Owens Ford and Owens-Illinois Inc. The latter company's headquarters building will remain the city's tallest structure — by a 60-ft. margin over the pylon.
Such a condition is created as the cradles bear upon the pylon, which thereby carries the 42,000-ton weight of the main span unit.

The stadium’s damper system disconnects the roof from the concrete support pylons so the roof structure is able to slide in the north-south direction during an earthquake.
The system disconnects the roof from the concrete support pylons so that the roof structure is able to slide in the north-south direction.
By disconnecting the heavy mass of the roof from the pylons, earthquake forces are greatly reduced.

The TTR/MTR tower consisted of a freestanding, concrete pylon assembled from cylindrical, reinforced concrete pipe sections.
Situated atop this column was a reinforced concrete platform, square in plan view, measuring 16-feet on each side.
Surrounding this concrete structure was a separate, open "skeletal" framework of steel beams, resting on its own foundation footings, which supported walkways surrounding the top of the tower and a ladder.

For many years a small, drab, concrete pylon marked the site -- nothing like the 56-foot-tall Golden Spike replica, relic of some forgotten movie promotion -- that casts a shadow of shame over Council Bluffs, Iowa -- eastern terminus of the Union Pacific's road and a city obviously IN BED with the Feds.
The pylon has since been moved into nearby Strasburg, where it stands in Lions Park next to the monkey bars.
Just a tiny park with a swing set on one end, the pylon on the other, and a lot of quiet pride and courage in between.

In another case, the Army special forces and FMLN engaged in two hours of fighting around a school where 40 children were trapped: as in a miracle, not a single child was injured.
It was not before July 1991, that the first concrete achievement of the peace process was reached, when the Government and the FMLN signed a broad human rights accord, setting out obligations for both sides in the conflict to avoid practices that endanger civilians.
