MBL nedir? (Minimum Breaking Load)<\/h2>\n

MBL (Minimum Breaking Load) — Minimum Kopma Y\u00fck\u00fc<\/strong>, bir halat\u0131n, sapan\u0131n veya ba\u011flant\u0131 eleman\u0131n\u0131n laboratuvar ortam\u0131nda \u00e7ekme testine tabi tutuldu\u011funda kopmas\u0131 garanti edilen en d\u00fc\u015f\u00fck y\u00fckt\u00fcr<\/strong>. EN 12385-4 ve ISO 3108 standartlar\u0131na g\u00f6re yap\u0131lan akredite \u00e7ekme testlerinde elde edilen de\u011ferdir.<\/p>\n

SWL nedir? (Safe Working Load)<\/h2>\n

SWL (Safe Working Load) — G\u00fcvenli \u00c7al\u0131\u015fma Y\u00fck\u00fc<\/strong>, tarihsel olarak 1990’l\u0131 y\u0131llara kadar kald\u0131rma ekipmanlar\u0131 \u00fczerinde belirtilen “sahada y\u00fcklenebilecek azami y\u00fck”<\/em> de\u011feriydi.

SWL terimi 1998 y\u0131l\u0131nda \u0130ngiltere’de y\u00fcr\u00fcrl\u00fc\u011fe giren LOLER (Lifting Operations and Lifting Equipment Regulations)<\/strong> mevzuat\u0131 ve e\u015f zamanl\u0131 AB direktifleriyle birlikte yasal olarak terk edilmi\u015ftir<\/strong>. Bunun temel sebebi, “g\u00fcvenli” kelimesinin operat\u00f6r nezdinde “y\u00fcklensek bile sorun olmaz” alg\u0131s\u0131 yaratmas\u0131 ve dinamik y\u00fck, a\u00e7\u0131 kayb\u0131, korozyon gibi etkenleri kapsamamas\u0131yd\u0131. 2026 itibar\u0131yla SWL terimini yaln\u0131zca eski ekipmanlar\u0131n \u00fczerinde, eski sertifikalarda veya baz\u0131 T\u00fcrk sat\u0131c\u0131lar\u0131n h\u00e2l\u00e2 al\u0131\u015fkanl\u0131k olarak kulland\u0131\u011f\u0131 bro\u015f\u00fcrlerde g\u00f6r\u00fcrs\u00fcn\u00fcz; yeni sertifikal\u0131 \u00fcr\u00fcnlerde yasal terim de\u011fildir.<\/p>\n

WLL nedir? (Working Load Limit)<\/h2>\n

WLL (Working Load Limit) — \u00c7al\u0131\u015fma Y\u00fck\u00fc Limiti<\/strong>, SWL terimi yerine ge\u00e7en g\u00fcn\u00fcm\u00fcz\u00fcn ge\u00e7erli yasal ve standart terimidir<\/strong>.
