سلسلة الرفع العلوية

The primary function of سلسلة الرفعs is to facilitate safe and efficient lifting and rigging operations. They are used to create a secure connection between the load and the lifting device. Lifting chains distribute the load's weight evenly, ensuring stability and reducing the risk of load shifting or accidents. They allow for controlled lifting, lowering, and positioning of heavy loads with precision. Lifting chains provide reliable load-bearing capabilities, enabling the safe movement of objects in various industries, including construction, manufacturing, and logistics.

There are different types of سلسلة الرفعs available, designed to suit specific load requirements and lifting applications. Grade 80 chains are commonly used for general lifting purposes, offering a good balance between strength and affordability. Grade 100 chains provide higher strength and load-bearing capacity, making them suitable for heavy-duty lifting tasks. Additionally, stainless steel chains are available for applications that require corrosion resistance. The choice of سلسلة الرفع depends on factors such as load weight, working conditions, and safety regulations.

عادة ما تكون سلاسل الرفع مصنوعة من سبائك الصلب عالية الجودة ، والتي توفر قوة ومتانة ممتازة. وهي تتكون من سلسلة من الروابط المترابطة التي تشكل سلسلة مستمرة. تتوفر سلاسل الرفع بأحجام ودرجات وتكوينات مختلفة لتتناسب مع متطلبات الحمل المحددة. قد تتميز بأنواع مختلفة من التركيبات الطرفية ، مثل الخطافات أو الأغلال أو الحلقات ، لتوصيل مريح بأجهزة الرفع. تم تصميم سلاسل الرفع لتلبية معايير ولوائح الصناعة الخاصة بسعة التحميل والسلامة والأداء.

Alloy Chain Grade 80 or Grade 100 should be used for overhead lifting. ASTM states that alloy chain shall be able to elongate a minimum of 20% before fracture (7.3.5). To ensure that alloy chain consistently meets this requirement, ASTM requires the use of certain alloying elements in the manufacturing of the steel for alloy steel chain. These alloys can vary from company to company, but some key requirements are specified by ASTM. The alloy properties also improve the wear and tear that the chain will experience.  Note that when chain is in use, no amount of stretch is allowed.
