Nahiz eta emakida 1895. urteko urtarrilak 5ean lortu, presa ez zen bukatu 1929.ko ekainak 19a arte. Lortutako indarra bertan erabiltzen zen, Alberdi Hermanos S.A. enpresan bertan.
Sarrerako erretena lantegiaren azpitik pasatzen zen, eta irterakoaren zati bat ere. Irteerako erretenaren bukaera gainean Churruca y Cia eraikina eraiki zuten.
