Dans « la cité du poids lourd » : la forge Berliet

La forge de l’usine Berliet de Vénissieux, construite en 1917, est une véritable « cathédrale industrielle »  : d’une longueur de 250 m et 58 m de large, elle est divisée en trois halls. La hauteur de faîtage du hall central est de 27 m. Il faut dire qu’elle a été à l’origine étudiée et équipée pour satisfaire à l’ensemble des besoins de l’entreprise : toutes les pièces forgées, depuis celles de 40 grammes jusqu’aux vilebrequins de 300 kg, entrant dans la composition des véhicules y sont fabriqués.


A partir des années 60, les moyens de forgeage de petite capacité sont supprimés dans le but de libérer des surfaces  : les  fabrications correspondantes  sont abandonnées à la sous-traitance. La vocation de la forge a donc évolué au fil des années en orientant ses techniques et ses investissements vers les pièces moyennes et lourdes.


Quelques repères chronologiques :

En 1923, le matériel de fabrication se compose de 17 marteaux-pilons, 14 presses à ébarber, 2 machines à refouler. 11 chaudières fournissent la vapeur aux pilons et 35 fours à réchauffer desservent ceux-ci. Ces fours confèrent au lopin* à forger une température de 800°à 1000°.Un pont roulant de 20 tonnes assure la manutention sur toute la longueur du bâtiment. Production mensuelle : 300 tonnes de pièces forgées.

En 1957, les forges de Berliet sont, par leur importance, les secondes de France derrière la Société des forges et ateliers du Creusot (Schneider). Elles s’étendent sur 20 000 m². Le matériel de fabrication est de 40 marteaux-pilons dont un de 7, 5 tonnes et deux de 5 tonnes de masse tombante, d’une presse à calibrer de 1000 tonnes, de trois machines à forger horizontales pour les pièces longues, d’une machine à forger réglable pour les pièces spécifiques. Production mensuelle : 800 tonnes de grosses pièces et 300 tonnes de ressorts à lame. L’effectif des forges s’élève à 380 personnes.

En 1967, les fours à réchauffer placés derrière les marteaux-pilons, sont à présent alimentés au gaz de Lacq. Résultat :  la qualité de chauffe (1000° à 1300°) est plus homogène et le travail moins pénible. La production mensuelle passe à 1200.tonnes de pièces forgées. L’effectif est de 430 personnes.

En 1974, de nouveaux investissements accroissent la capacité de production des vilebrequins et des essieux qui passent à 3500 pièces par mois. La production mensuelle est de 2000 tonnes de pièces forgées.L’effectif atteint 500 personnes.

En 1984 : L’outil industriel de la forge se compose de 10 marteaux-pilons de 1,8 tonnes à 16 tonnes, de 2 machines à forger horizontales, de 3 maxi-presses. La production mensuelle est de 3000 tonnes de pièces forgées. L’effectif est de 302 personnes.


Dans les années 90, la forge va réduire son activité de façon significative. En 1999, les marteaux-pilons se sont arrêtés définitivement après 82 ans de vacarme !… mais le bâtiment presque centenaire existe encore aujourd’hui, témoin devenu muet d’une  autre  époque industrielle.

* lopin : morceau de métal débité à la dimension voulue et chauffé avant d’être transformé (estampage, forgeage, ébarbage…). En 1958, le poids d’un lopin pouvait aller de 200 g à 300 kg !

Fake Ski Team Scammed The Olympics And The Press

Di Silvestri and Morrone, you may recall, traveled to Sochi bearing the flag of Dominica, an island in the Lesser Antilles region of the Caribbean. This may seem odd, since Gary’s a native of Staten Island, Angelica’s an Italian national, and they live in a mountain palace in Montana. But then, Dominica is the sort of country that tries to sell you « economic citizenship » on its website. Any married couple from anywhere can become Dominicans by depositing $175,000 « into the appropriate account at the National Commercial Bank of Dominica, » and paying the Ministry of Finance another $3,530 in wholesale jerseys tariffs and fees. Di Silvestri and Morrone just went one better by finagling their way onto the nation’s previously nonexistent winter Olympics team.

Neither was expected to ski onto a podium in Sochi, but their showing makes a great case for closing the eligibility loopholes that allow moneyed pranksters to dress up as Olympians. Morrone listed at 48 years old, which would have made her the oldest Olympic cross country skier of all time by seven years didn’t even show up for the 10K women’s classic on Feb. 13, claiming injury. (She was the only one of the race’s 76 entrants who didn’t start.) A day later, in the 15K men’s classic, di Silvestri, 47, made it out of the starting gate but gave up just a few hundred meters later, claiming illness. cheap authentic jerseys He was reportedly the only starter who failed to make even the first checkpoint. There is no mention of any city or state championships anywhere in his Monsignor Farrell yearbook entry (class of ’85). And a 2000 article for the Staten Island Advance, a local newspaper, about di Silvestri paying $100,000 for naming rights to the wrestling room at his old high school, alerts readers to no schoolboy titles of note. When he was subsequently inducted into Monsignor Farrell’s Hall of Fame, the write up notes that di Silvestri was a « Staten Island Advance All Star » as a wrestler, but says nothing about city or state championships.

Steve Meehan, a wrestling obsessive from Long Island who has compiled a comprehensive history of the New York state championship meets from 1962 through last year, says his records show that di Silvestri « was never » a state titlist. In fact, di Silvestri’s name doesn’t show up anywhere in Meehan’s database, which includes the top six finishers for every year in the last half century. The state meet is called the New York State Public High School Athletic Association championship, but Catholic school wrestlers compete for NYSPHSAA state titles; in the championship meet in 1985, di Silvestri’s senior year, Daryl Page from Elmira Notre Dame, a Catholic school, captured the first of what would be three New York state championships. And Meehan’s database shows other Monsignor Farrell wrestlers have placed among the top six finishers six times in the meet’s history.

Di Silvestri attended Georgetown in the late 1980s. Sadly, no boat from Georgetown won an IRA championship during di Silvestri’s years at the school. This isn’t to say that Hoya rowers were slouches back then. A crew from Georgetown did win the cheap nfl jerseys lightweight eights bracket of the 1989 Dad Vail Regatta, an event held annually on the Schuylkill River in Philadelphia. The cheap jerseys from china Dad Vail attracts smaller (and smaller budgeted) college boating operations than the IRA regatta, but in some crew centric corners it is considered « the national championship for the little guy. »

Hodler said the Italian lobby, directed by Fiat head Gianni Agnelli, was particularly aggressive. The whistleblower took lots of heat from fellow sports administrators who should have cheered him on for exposing corruption. IOC head Juan Antonio Samaranch, for example, not only said Hodler should have kept his corruption charges in house, but he also publicly defended the accused. « We are extremely sorry if these statements have caused pain and embarrassment to the Agnelli family and Fiat, » Samaranch said. ski team and IOC voter, came out in support of Hodler. Peterson seconded the claims Hodler had made against Fiat and went so far as to name more names ending in vowels. Peterson said that during the debate over who would host the 1997 skiing world championships, Fiat offered him two of the company’s cars in exchange for voting to award the event to Sestriere, Italy.Articles Connexes:
