Die klant het voorheen die oorhoofse hyskraan by ander verskaffers gekoop, maar het gevind dat die hyskraan se relings en wiele kort n\u00e1 gebruik ernstig beskadig is, wat die produksie en gebruik be\u00efnvloed en &#039;n groot verlies veroorsaak het. SEVENCRANE het die rede vir die skade aan die kli\u00ebnt verduidelik nadat hy die werklike situasie van die kli\u00ebnt se hyskraan geken en ondersoek het. Die verskynsel van oorhoofse kraanspoor wat knaag, is deels te wyte aan die swak gehalte en deels aan die objektiewe faktore van onbehoorlike gebruik.<\/p>\n\n\n\n<p>SEVENCRANE het aan ons kli\u00ebnte ho\u00eb kwaliteit hyskraanwiele en hyskraanrelings verskaf en hulle stelselmatig opgelei in die behoorlike gebruik en instandhouding van brughyskrane. Baie kli\u00ebnte het hul dankbaarheid en lof aan SEVENCRANE uitgespreek en langtermyn samewerkingsooreenkomste onderteken.<\/p>\n\n\n\n<p>Ten einde klante te help om die risiko van stilstand as gevolg van spoorknaag van brughyskrane te verminder, verliese en onderhoudskoste te verminder, het SEVENCRANE spesiaal die Redes vir spoorknaag van oorhoofse hyskrane uitgesorteer vir klante om te lees en te leer.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Redes vir spoor knaag van oorhoofse hyskrane<\/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=\"spoor knaag probleem van oorhoofse hyskraan\" 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=\"spoor knaag probleem van oorhoofse hyskraan\" 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.
