lifting chain

  In industries such as transportation, lifting, and secure fastening, the strength and quality of chains are crucial. Chain grades are an important standard for measuring the strength of chains, and different grades are suitable for various applications. Definition of Chain Grades Chain grades are used to measure the strength of chains, typically based on tensile strength and working load limit (WLL). Different chain grades have varying materials and heat treatment processes, affecting their load-bearing capacity and durability. Chain grades are usually denoted by “G” followed by a number, such as G30, G43, G70, G80, G100, and G120. Common Chain Grades and Their Characteristics Chain Grade Strength Level Material & Treatment Applications Suitability for Lifting G30 (Grade 30) Low Low-carbon steel Agriculture, household use, decoration, light-duty towing  Not suitable G43 (Grade 43) Medium Carbon steel, stronger than G30 Marine, forestry, industrial applications, medium-st...

  Load Binder is a vital tool in cargo transportation and lifting operations. Its main function is to ensure that the cargo is firmly fixed during transportation to prevent the cargo from shifting or loosening due to vibration, bumps or external forces. Load Binder ensures the safety of transportation by tightening the chain and stabilizing the load. What are the differences between the US load binder and European type load binder? Grade : US-type ratchet load is G70, while European-type is G80. Hook : US-type ratchet load is the flat hook, while European-type ratchet load is a grab hook with a safety latch Standard : European type EN12195-3, US type ASTM. The parameters of each load binder US Type Load binder SIZE(Inch) WLL(lbs) Proof Load(lbs) Breaking Load(lbs) Handle Length(Inch) 1/4-5/16" 2600 5200 9200 7.16 5/16-3/8" 5400 10800 19000 13.42 3/8-1/2" 9200 18400 33000 13.92 1/2-5/8" 13000 26000 46000 21 European Type Load...

  Ratchet straps are essential for securing cargo and ensuring transportation safety. However, frequent use can lead to issues such as the ratchet mechanism getting stuck, making it difficult to release. This not only slows down your work but also poses safety risks. In this guide, we’ll explore the main reasons why ratchet straps get stuck, how to fix them, and best practices to prevent future problems. www.chinatoplifting.com tracy@chinatoplifting.com Common Causes of a Stuck Ratchet Mechanism Dirt and Rust Build-Up Over time, dust, grease, or moisture can accumulate in the ratchet mechanism, preventing smooth operation. Exposure to moisture may cause rust, making the metal parts seize up. Excessive Use or Wear and Tear Constant heavy use may cause the ratchet’s gears and springs to wear out or deform, leading to difficulty in releasing the strap. The webbing may also fray or get stuck inside the mechanism, making it hard to loosen. Inco...
