วิธีการจับคู่โซ่, รถเครน, and Load Requirements in Modern Lifting Operations
In any lifting task—whether industrial, อิงคลังสินค้า, or on construction sites—safety starts with the right components. หนึ่งในสิ่งที่สำคัญที่สุด, และมักจะเข้าใจผิด, factors in material handling is the chain working load. Selecting the wrong chain can lead to equipment failure, injury, or property damage.
At Hebei Zoho Hoisting Machinery Manufacturing Co., จำกัด., we manufacture and supply lifting chains, portable floor cranes, และ small lifting cranes, all designed with safety, ผลงาน, and reliability in mind.
What Is Chain Working Load?
เดอะ chain working load (also known as working load limit or WLL) refers to the maximum amount of weight that a lifting chain can safely handle during routine operation. It is calculated based on:
- Material strength
- Chain diameter
- Design factor for safety margins
- Intended application and usage conditions
This value is not the breaking point, but the recommended safe operating limit, typically at one-third or one-fourth of the minimum breaking strength.
Why Working Load Matters in Crane Operations
Both portable floor cranes และ small lifting cranes rely on lifting chains to manage vertical loads. Using a chain with insufficient working load capacity can cause:
- Chain deformation or fracture
- Load dropping and uncontrolled descent
- Crane damage and long-term reliability issues
To avoid this, chains must always match or exceed the rated load capacity of the crane they are attached to.
Matching the Chain to the Crane
When selecting a chain for use with a เครนตั้งพื้นแบบพกพา หรือ เครนยกขนาดเล็ก, consider:
- Load capacity of the crane (เช่น. 500กิโลกรัม, 1 ตัน, 2 ตัน)
- Lift height and frequency of use
- ปัจจัยด้านสิ่งแวดล้อม like heat, ความชื้น, or corrosive conditions
- Chain grade (เช่น. G80, G100 for heavy-duty lifting)
ของเรา high-strength lifting chains at Zoho Hoist are engineered for compatibility with all standard and custom crane systems. Whether you’re lifting machinery in a factory or cargo in a warehouse, we ensure chain integrity and certification come standard.
