De klant had de bovenloopkraan al eerder bij een andere leverancier gekocht, maar constateerde dat de kraanrails en wielen van de kraan al snel na gebruik ernstig beschadigd raakten, wat de productie en het gebruik be\u00efnvloedde en een groot verlies veroorzaakte. SEVENCRANE legde de reden voor de schade aan de klant uit nadat hij de feitelijke situatie van de kraan van de klant kende en onderzocht. Het fenomeen van het knagen aan bovenloopkraanrails is deels te wijten aan de slechte kwaliteit en deels aan de objectieve factoren van oneigenlijk gebruik.<\/p>\n\n\n\n<p>SEVENCRANE voorzag onze klanten van hoogwaardige kraanwielen en kraanrails en trainde hen systematisch in het juiste gebruik en onderhoud van brugkranen. Veel klanten spraken hun dankbaarheid en lof uit aan SEVENCRANE en ondertekenden samenwerkingsovereenkomsten voor de lange termijn.<\/p>\n\n\n\n<p>Om klanten te helpen het risico op stilstand als gevolg van het knagen aan het spoor van brugkranen te verminderen en verliezen en onderhoudskosten te verminderen, heeft SEVENCRANE speciaal de redenen voor het knagen aan het spoor van bovenloopkranen uitgezocht, zodat klanten deze kunnen lezen en leren.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Redenen voor het knagen aan het spoor van bovenloopkranen<\/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=\"spoorknaagprobleem van bovenloopkraan\" 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=\"spoorknaagprobleem van bovenloopkraan\" 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.

Ten tweede bevindt de installatiepositie van de vier wielen zich niet op de vier hoeken van de rechthoek en ligt het midden van de wielen aan dezelfde kant niet in een rechte lijn, wat de afbuiging van de middellijn van de wielen vormt en het knagen van de rails veroorzaakt. . <\/p>\n<\/div><\/div>\n\n\n\n<h4 class=\"wp-block-heading\">2.

Wanneer de diagonale lengte groter is dan 5 mm of meer, wordt de overspanning groter dan het verschil. Als het positief is, knaagt het aan de binnenrand van het wiel; integendeel, het knaagt aan de buitenrand van het wiel.  <\/p>\n\n\n\n<p>Ten tweede zorgt de horizontale buiging van de eindbalk ervoor dat het wiel horizontaal afwijkt, zodat de hartlijn van het wiel en de hartlijn van het spoor niet in een rechte lijn liggen, waardoor dezelfde afwijking ontstaat en het knagen aan de rail ontstaat.  <\/p>\n\n\n\n<p>Ten derde veroorzaakt de verticale doorbuiging van het brugframe de verticale doorbuiging van het wiel, waardoor de hoek tussen de hartlijn van het loopvlak en de verticale lijn de rolstraal van het wiel verandert. Na belasting neemt de verticale doorbuiging aan de ene kant van het wiel geleidelijk toe, terwijl de verticale doorbuiging aan de andere kant afneemt, wat resulteert in een verschillende rolradius, wat resulteert in het knagen aan de rail. <\/p>\n<\/div><\/div>\n\n\n\n<h4 class=\"wp-block-heading\">4.
