The VOLSN CD Vertical Lifting Clamp<\/b> is an industrial-grade rigging solution engineered strictly for the linear vertical lifting and transport of steel plates. Featuring a heavy-duty forged alloy steel body and a 4:1 safety factor<\/b>, it operates via a pre-tensioned spring-loaded self-locking mechanism<\/b> to ensure absolute jaw engagement under zero load. Designed strictly for straight, non-side-loading vertical maneuvers, this clamp accommodates plate surface hardness up to 37 HRC (345 HB)<\/b> and complies fully with CE\u00a0 standards<\/b> for heavy manufacturing and shipyards.<\/p>\n

    \n
  1. Strictly Rated for Straight Linear Vertical Transit:<\/b> The CD series features a high-rigidity standard lifting eye optimized exclusively for straight-line vertical lifting and lowering. To ensure absolute structural integrity, this model is designed without multi-angle articulation, meaning side-loading or angular lifting is strictly prohibited. It delivers maximum stability and resistance against deformation during linear plate transit across structural steel workshops.<\/li>\n
  2. Pre-Tensioned Spring-Loaded Safety Lever:<\/b> Equipped with a manual locking handle, the internal mechanism applies an immediate, robust clamping force onto the plate surface before the hoist line tightens. This self-locking design guarantees the jaws remain firmly engaged in both open and closed positions, eliminating any risk of slippage when setting down loads or during sudden crane speed changes.<\/li>\n
  3. High-Wear Resistant Induction-Hardened Alloy Jaws:<\/b> The cam and pivoting jaw liner are die-forged from premium chromium-molybdenum alloy steel to handle high-frequency operation. It delivers absolute structural integrity for gripping structural plates with a maximum surface hardness of 37 HRC (345 HB)<\/b>, ensuring optimal teeth penetration without damaging the jaw profiles.<\/li>\n<\/ol>\n

    Technical Safety Note: Every VOLSN CD vertical lifting clamp is individually proof-tested to 2 x WLL (Working Load Limit)<\/b>. The minimum load applied must be at least 10% of the rated capacity. Always ensure the lifting line is perfectly aligned vertically; do not subject the standard CD lifting eye to side or lateral angular forces.<\/h6>\n

      Q: Can the VOLSN CD vertical lifting clamp be used for side-loading or turning plates from horizontal to vertical?<\/b><\/p>\n

        \n
      • \n

        A:<\/b> No, the standard CD vertical lifting clamp is strictly engineered for linear, straight-line vertical lifting and must never be used for side-loading or turning operations.<\/b> Because it lacks an articulated universal joint, applying lateral or angular forces can bend the lifting eye or result in catastrophic load slippage; for flipping or turning operations, a model with a rotating shackle must be used.<\/p>\n<\/li>\n<\/ul>\n<\/li>\n

        Q: What is the purpose of the manual safety lever on the CD lifting clamp?<\/b><\/p>\n

          \n
        • \n

          A:<\/b> The manual safety lever activates a pre-tensioned spring mechanism that forces the jaw to grip the steel plate before any lifting tension is applied by the crane.<\/b> This ensures that the clamp remains locked onto the load even under zero-load conditions, preventing accidental release if the plate strikes an obstacle or during placement.<\/p>\n<\/li>\n<\/ul>\n<\/li>\n

          Q: What is the maximum plate hardness that the CD series can safely grip?<\/b><\/p>\n

            \n
          • \n

            A:<\/b> The maximum surface hardness for steel plates handled by the CD clamp is 37 HRC (345 HB).<\/b> The hardened alloy teeth require a slight surface penetration to achieve a secure friction grip; materials exceeding 37 HRC or stainless steel plates will resist this penetration and may cause dangerous slipping (non-marring clamps should be used for stainless steel).<\/p>\n<\/li>\n<\/ul>\n<\/li>\n

          • \n

            Q: Does the VOLSN CD vertical lifting clamp come with compliance certificates for safety audits?<\/b><\/p>\n

              \n
            • \n

              A:<\/b> Yes, every individual CD clamp fully complies with European CE (EN13155) and German GS standards and is shipped with an official Mill Test Certificate.<\/b> Each unit undergoes a 200% proof-load test at the factory to verify its 4:1 safety factor, making it fully ready for strict third-party site safety inspections.<\/p>\n<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n
