Il cliente aveva gi\u00e0 acquistato il carroponte da un altro fornitore, ma subito dopo l&#039;uso ha riscontrato che le rotaie e le ruote della gru erano state gravemente danneggiate, il che ha influito negativamente sulla produzione e sull&#039;utilizzo e ha causato una grave perdita. SEVENCRANE ha spiegato al cliente il motivo del danno dopo aver conosciuto e indagato la situazione reale della gru del cliente. Il fenomeno della roditura delle rotaie dei carriponte \u00e8 dovuto in parte alla scarsa qualit\u00e0 ed in parte a fattori oggettivi di uso improprio.<\/p>\n\n\n\n<p>SEVENCRANE ha fornito ai nostri clienti ruote e rotaie per gru di alta qualit\u00e0 e li ha formati sistematicamente sull&#039;uso e la manutenzione corretti dei carroponti. Molti clienti hanno espresso la loro gratitudine e lode a SEVENCRANE e hanno firmato accordi di cooperazione a lungo termine.<\/p>\n\n\n\n<p>Per aiutare i clienti a ridurre il rischio di tempi di inattivit\u00e0 dovuti al rosicchiamento delle rotaie dei carroponti, ridurre le perdite e i costi di manutenzione, SEVENCRANE ha selezionato appositamente i motivi del rosicchiamento delle rotaie dei carroponti affinch\u00e9 i clienti possano leggerli e impararli.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Ragioni per il rosicchiamento delle rotaie dei carroponti<\/strong><\/h3>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"data:image\/gif;base64,R0lGODlhAQABAIAAAAAAAP\/\/\/yH5BAEAAAAALAAAAAABAAEAAAIBRAA7\" data-src=\"https:\/\/d3fnmw4lwrx8lm.cloudfront.net\/wp-content\/uploads\/2019\/10\/22173347\/rail-gnawing-problem-of-overhead-crane.jpg\" alt=\"problema del carroponte che rode la rotaia\" class=\"wp-image-3873 lazyload\"\/><noscript><img decoding=\"async\" width=\"722\" height=\"255\" src=\"https:\/\/d3fnmw4lwrx8lm.cloudfront.net\/wp-content\/uploads\/2019\/10\/22173347\/rail-gnawing-problem-of-overhead-crane.jpg\" alt=\"problema del carroponte che rode la rotaia\" class=\"wp-image-3873 lazyload\" srcset=\"https:\/\/d3fnmw4lwrx8lm.cloudfront.net\/wp-content\/uploads\/2019\/10\/22173347\/rail-gnawing-problem-of-overhead-crane.jpg 722w, https:\/\/d3fnmw4lwrx8lm.cloudfront.net\/wp-content\/uploads\/2019\/10\/22173347\/rail-gnawing-problem-of-overhead-crane-300x106.jpg 300w\" sizes=\"(max-width: 722px) 100vw, 722px\" \/><\/noscript><\/figure>\n\n\n\n<h4 class=\"wp-block-heading\">1.
