Safety Rules &amp; Best Practices<\/h6><p><br>Can a horizontal lifting clamp be used alone? Learn why horizontal lifting clamps must always be used in pairs with a spreader beam, understand the safety risks, and discover industry best practices for steel plate handling.<\/p><h1 class=\"wp-block-heading\">Can a Horizontal Lifting Clamp Be Used Alone?<\/h1><h2 class=\"wp-block-heading\">Quick Answer<\/h2><p><strong>No. A horizontal lifting clamp should never be used alone to lift a steel plate.<\/strong><\/p><p>Horizontal lifting clamps are designed to work <strong>in pairs (2 clamps)<\/strong> or <strong>sets of four (4 clamps)<\/strong> together with a properly rated <strong>spreader beam<\/strong> or <strong>lifting beam<\/strong>. Using a single horizontal clamp can cause load imbalance, plate slippage, excessive bending, and potentially catastrophic lifting failures. For single-point lifting, a <strong>vertical lifting clamp<\/strong> such as a CD or CDH model is the appropriate solution.<\/p><h1 class=\"wp-block-heading\">Key Takeaways<\/h1><ul class=\"wp-block-list\"><li><strong>A single horizontal lifting clamp is not designed to safely support a steel plate.<\/strong><\/li>\n\n<li><strong>Horizontal lifting clamps must always be used in pairs or sets of four.<\/strong><\/li>\n\n<li><strong>A spreader beam is essential to distribute the load evenly between clamps.<\/strong><\/li>\n\n<li><strong>Thin, long, or wide plates are especially vulnerable to sagging without proper support.<\/strong><\/li>\n\n<li><strong>For single-point lifting, choose a vertical lifting clamp instead of a horizontal clamp.<\/strong><\/li><\/ul><h1 class=\"wp-block-heading\">Why Can&#8217;t a Horizontal Lifting Clamp Be Used Alone?<\/h1><p>The answer lies in <strong>load distribution<\/strong>.<\/p><p>Horizontal lifting clamps grip the plate from its edges. Unlike vertical lifting clamps, they do not suspend the load directly beneath the lifting point. Instead, they rely on multiple lifting points to keep the plate balanced.<\/p><p>If only one horizontal clamp is used:<\/p><ul class=\"wp-block-list\"><li>The steel plate rotates toward its center of gravity.<\/li>\n\n<li>The clamp experiences uneven side loading.<\/li>\n\n<li>The gripping force may become insufficient.<\/li>\n\n<li>The plate can slip from the clamp.<\/li>\n\n<li>The lifting operation becomes unstable and unsafe.<\/li><\/ul><p>This is why manufacturers and industry standards require horizontal clamps to be used as part of a complete lifting system\u2014not as standalone lifting devices.<\/p><h1 class=\"wp-block-heading\">The Correct Way to Use Horizontal Lifting Clamps<\/h1><p>The recommended configuration includes:<\/p><ul class=\"wp-block-list\"><li><strong>2 horizontal lifting clamps<\/strong> for standard steel plates.<\/li>\n\n<li><strong>4 horizontal lifting clamps<\/strong> for large, heavy, or oversized plates.<\/li>\n\n<li>A <strong>spreader beam (lifting beam)<\/strong> connected to the crane hook.<\/li>\n\n<li>Properly rated slings or chain assemblies.<\/li><\/ul><h3 class=\"wp-block-heading\">Typical Lifting Configuration<\/h3><pre class=\"wp-block-code\"><code>          Crane Hook<br>               \u2502<br>        Spreader Beam<br>          \/          \\<br>     Sling          Sling<br>        \u2502              \u2502<br>

plate deflection.<\/p><h1 class=\"wp-block-heading\">Why Is a Spreader Beam Required?<\/h1><p>A spreader beam performs several critical functions:<\/p><ul class=\"wp-block-list\"><li>Maintains equal load sharing between clamps.<\/li>\n\n<li>Prevents inward pulling forces.<\/li>\n\n<li>Reduces bending stress on thin plates.<\/li>\n\n<li>Improves lifting stability.<\/li>\n\n<li>Protects the plate from permanent deformation.<\/li><\/ul><p>Without a spreader beam, the lifting angle changes during the lift, increasing stress on both the clamps and the steel plate.<\/p><p>For thin plates, the absence of a spreader beam significantly increases the risk of sagging and clamp slippage.<\/p><h1 class=\"wp-block-heading\">Horizontal vs. Vertical Lifting Clamps<\/h1><figure

class=\"wp-block-list\"><li>Only one lifting point is available.<\/li>\n\n<li>Thick steel plates need to be moved vertically.<\/li>\n\n<li>Plates must be turned from horizontal to vertical.<\/li>\n\n<li>Fabrication or welding operations require upright positioning.<\/li><\/ul><p>Vertical lifting clamps such as <strong>CD<\/strong> and <strong>CDH<\/strong> models use a cam-lock mechanism that increases gripping force as the applied load increases, making them suitable for single-point lifting applications.<\/p><h1 class=\"wp-block-heading\">Common Mistakes to Avoid<\/h1><h3 class=\"wp-block-heading\">Using One Horizontal Clamp<\/h3><p>This is one of the most dangerous errors in steel handling.<\/p><p>Possible consequences include:<\/p><ul class=\"wp-block-list\"><li>Plate slipping<\/li>\n\n<li>Load imbalance<\/li>\n\n<li>Clamp overload<\/li>\n\n<li>Plate damage<\/li>\n\n<li>Serious workplace injuries<\/li><\/ul><h3 class=\"wp-block-heading\">Skipping the Spreader Beam<\/h3><p>Some operators connect two horizontal clamps directly to a crane hook using short slings.<\/p><p>This creates inward pulling forces that reduce clamp performance and increase instability.<\/p><p>Always use a properly rated spreader beam unless the clamp manufacturer explicitly specifies another approved lifting arrangement.<\/p><h3 class=\"wp-block-heading\">Ignoring Plate Dimensions<\/h3><p>Large plates may require four lifting clamps instead of two.<\/p><p>Always consider:<\/p><ul class=\"wp-block-list\"><li>Plate length<\/li>\n\n<li>Plate width<\/li>\n\n<li>Plate thickness<\/li>\n\n<li>Plate weight<\/li>\n\n<li>Center of gravity<\/li><\/ul><p>before planning a lift.<\/p><h1 class=\"wp-block-heading\">Safety Notes<\/h1><p>For safe lifting operations:<\/p><ul class=\"wp-block-list\"><li>Inspect lifting clamps before every use.<\/li>\n\n<li>Verify the Working Load Limit (WLL).<\/li>\n\n<li>Confirm the allowable plate thickness range.<\/li>\n\n<li>Never exceed the rated capacity.<\/li>\n\n<li>Never side-load a lifting clamp.<\/li>\n\n<li>Never use damaged or excessively worn clamp teeth.<\/li>\n\n<li>Ensure all lifting accessories are compatible and properly rated.<\/li>\n\n<li>Follow the manufacturer&#8217;s operating instructions at all times.<\/li><\/ul><p>Remember that a lifting system is only as safe as its weakest component.<\/p><h1 class=\"wp-block-heading\">Frequently Asked Questions<\/h1><h2 class=\"wp-block-heading\">Can I lift a steel plate with one horizontal lifting clamp?<\/h2><p>No. Horizontal lifting clamps are designed to be used in pairs or sets of four together with a spreader beam.<\/p><h2 class=\"wp-block-heading\">Why do horizontal lifting clamps require two clamps?<\/h2><p>Two clamps distribute the load evenly, keep the plate balanced, and reduce the risk of slippage or deformation.<\/p><h2 class=\"wp-block-heading\">Do all horizontal lifting clamps require a spreader beam?<\/h2><p>In most steel plate lifting applications, yes. A spreader beam helps maintain proper lifting geometry and equal load distribution.<\/p><hr class=\"wp-block-separator has-alpha-channel-opacity\"\/><h2 class=\"wp-block-heading\">What happens if I use one horizontal clamp?<\/h2><p>The plate may rotate, bend, slip from the clamp, or overload the lifting system, creating a serious safety hazard.<\/p><h2 class=\"wp-block-heading\">Which clamp should I use for single-point lifting?<\/h2><p>A vertical lifting clamp, such as a CD or CDH model, is designed for single-point lifting applications.<\/p><h2 class=\"wp-block-heading\">Can horizontal lifting clamps lift thin steel plates?<\/h2><p>Yes. They are often the preferred choice for thin plates when used correctly with two or four clamps and a spreader beam.<\/p><h2 class=\"wp-block-heading\">How many clamps are required for large steel plates?<\/h2><p>Two clamps are suitable for many standard applications, while very long, wide, or heavy plates often require four clamps to improve stability and distribute the load.<\/p><h1 class=\"wp-block-heading\">References<\/h1><p>The recommendations in this article are based on widely recognized lifting practices and internationally accepted standards, including:<\/p><ul class=\"wp-block-list\"><li><strong>ASME B30.20<\/strong> \u2013 Below-the-Hook Lifting Devices<\/li>\n\n<li><strong>ASME BTH-1<\/strong> \u2013 Design of Below-the-Hook Lifting Devices<\/li>\n\n<li><strong>EN 13155<\/strong> \u2013 Cranes \u2013 Safety \u2013 Non-fixed Load Lifting Attachments<\/li>\n\n<li><strong>ISO 12100<\/strong> \u2013 Safety of Machinery \u2013 General Principles for Risk Assessment and Risk Reduction<\/li>\n\n<li>Manufacturer operating manuals and inspection guidance for plate lifting clamps<\/li><\/ul><p>Always refer to the latest edition of the applicable standards and the specific instructions provided by the clamp manufacturer.<\/p><h1 class=\"wp-block-heading\">Expert Recommendation<\/h1><p>Selecting the correct lifting clamp is not only about load capacity\u2014it also depends on the lifting direction, plate dimensions, and rigging configuration.<\/p><p>For horizontal steel plate handling, the safest practice is to use <strong>paired horizontal lifting clamps with a properly rated spreader beam<\/strong> to maintain balanced load distribution and reduce plate deformation.<\/p><p>For vertical transport or single-point lifting of thick steel plates, <strong>CD and CDH vertical lifting clamps<\/strong> provide a secure and efficient solution when used within their specified working load and thickness ranges.<\/p><p>At <strong>Volsn<\/strong>, we recommend evaluating each lifting application based on <strong>plate weight, thickness, lifting orientation, and the complete lifting system<\/strong> rather than selecting a clamp solely by its rated capacity. Matching the right clamp to the right application helps improve safety, extend equipment service life, and ensure efficient material handling.<\/p><p><\/p>","protected":false},"excerpt":{"rendered":"<p>Can a Horizontal Lifting Clamp Be Used Alone?
