Pelanggan membeli derek di atas kepala dari pemasok lain sebelumnya, tetapi menemukan bahwa rel derek dan roda derek rusak parah segera setelah digunakan, yang mempengaruhi produksi dan penggunaan serta menyebabkan kerugian besar. SEVENCRANE menjelaskan penyebab kerusakan tersebut kepada pelanggan setelah mengetahui dan menyelidiki keadaan sebenarnya dari crane pelanggan. Fenomena menggerogoti rel derek di atas kepala sebagian disebabkan oleh kualitas yang buruk dan sebagian lagi karena faktor obyektif dari penggunaan yang tidak tepat.<\/p>\n\n\n\n<p>SEVENCRANE menyediakan roda derek dan rel derek berkualitas tinggi kepada pelanggan kami dan secara sistematis melatih mereka dalam penggunaan dan pemeliharaan derek jembatan dengan benar. Banyak pelanggan yang mengucapkan terima kasih dan pujian kepada SEVENCRANE dan menandatangani perjanjian kerja sama jangka panjang.<\/p>\n\n\n\n<p>Untuk membantu pelanggan mengurangi risiko waktu henti akibat menggerogoti rel pada derek jembatan, mengurangi kerugian dan biaya pemeliharaan, SEVENCRANE secara khusus memilah Alasan menggerogoti rel pada derek di atas kepala agar pelanggan dapat membaca dan mempelajarinya.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Alasan rel menggerogoti derek di atas kepala<\/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=\"masalah kereta api yang menggerogoti derek di atas kepala\" 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=\"masalah kereta api yang menggerogoti derek di atas kepala\" 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.
