The VOLSN CDH Vertical Lifting Clamp<\/b> is a standard industrial rigging tool engineered exclusively for the vertical lifting, hoisting, and lateral transport of steel plates and concrete structures. Featuring a rigid, non-articulated standard rigging eye, it provides an optimized, direct line of force for steady vertical orientation. Built with a high-strength forged alloy steel body and a 5:1 safety factor<\/b>, the CDH clamp incorporates an automatic pre-tensioned locking lever to guarantee secure, slip-free clamping for steel surface hardness up to 37 HRC<\/b>.<\/p>\n

  1. Rigid Standard Rigging Eye for Steady Hoisting:<\/b> Designed with a fixed, heavy-duty rigging eye, the CDH clamp ensures a direct alignment of the lifting force during purely vertical transport. This non-articulated structure minimizes plate swaying and shifting during linear crane movements.<\/li>\n
  2. Rigid Standard Rigging Eye for Steady Hoisting:<\/b> Designed with a fixed, heavy-duty rigging eye, the CDH clamp ensures a direct alignment of the lifting force during purely vertical transport. This non-articulated structure minimizes plate swaying and shifting during linear crane movements.<\/li>\n
  3. Induction-Hardened Forged Cam & Jaw:<\/b> The structural core features high-grade forged alloy steel teeth that resist deformation under extreme structural loading. It delivers optimal friction grip for industrial carbon steel plates up to 37 HRC (345 HB)<\/b>.<\/li>\n<\/ol>\n

      Q1: Can the CDH vertical lifting clamp be used for turning or flipping steel plates?<\/b><\/p>\n

        \n
      • \n

        A1\u00a0 :<\/b> No, the CDH clamp must not<\/b> be used for turning or flipping plates. Its fixed rigging eye is engineered strictly for straight-line vertical hoisting; any side-loading or angular force will compromise safety and damage the clamp body.<\/p>\n<\/li>\n<\/ul>\n<\/li>\n

        Q2: What is the maximum material hardness the CDH clamp can safely grip?<\/b><\/p>\n

          \n
        • \n

          A2 :<\/b> The maximum allowable surface hardness for standard CDH clamps is 37 HRC (345 HB)<\/b>. Using it on harder materials like stainless steel or specialized armor plates may prevent the forged teeth from biting into the surface, causing potential slippage.<\/p>\n<\/li>\n<\/ul>\n<\/li>\n

          Q3: What safety standards does the VOLSN CDH clamp comply with?<\/b><\/p>\n

            \n
          • \n

            A3 :<\/b> Every CDH vertical clamp is manufactured in compliance with international rigging safety regulations, including ASME B30.20, EN 13155, and AS 4991<\/b>, and undergoes a 200% proof-load test before factory clearance.<\/p>\n<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n
