WHAT IS A BEAM CLAMP?
A beam clamp, also known as a girder clamp, is used to suspend or secure fixtures, wires, threaded rods and other hardware. It provides a simple and portable means of attaching a hoist to a runway or lifting beam. The design of a beam clamp features adjustable jaws, which can also be a fixed size, have scissor action, screw locking or bolt clamp fixing, suitable for temporary or permanent applications.
Beam clamps can be made from a selection of materials, including forged steel, cast iron or a high-grade alloy, giving them the strength to support heavy weights safely and reliably. Before we look at the types of beam clamps in more detail, the two most common are:
· Static clamps – these provide a fixed position
· Adjustable clamps – these can move or reposition along the beam
Beam clamps are widely used across construction, manufacturing, shipbuilding, mining, HVAC, warehousing, utilities and other industries where lifting, suspending or securing heavy equipment to structural steel is required.
WHAT ARE BEAM CLAMPS USED FOR?
You can expect to see beam clamps used for several applications for lifting, material handling and rigging. Industrial, commercial and construction environments where safe, secure attachment to structural steel is essential, beam clamps shine. Their primary purpose is to create a strong, non-invasive anchor point on beams, enabling several forms of suspended support or lifting.
· Lifting heavy loads:
Beam clamps are often paired with chain hoists and trolleys, lifting slings and several other pieces of lifting equipment to suspend and move equipment and materials safely. The beam clamp acts as a stable point of contact that avoids the need for welding or permanent fixtures.
· Supporting pipes, ductwork and cable trays:
In mechanical and HVAC settings, beam clamps support various systems, such as pipes, ductwork, cable trays and conduits, and ensure these systems are held securely in place. They’re also ideal for securing hoists and winches during maintenance and assembly tasks.
· Permanent or temporary solution:
Can you use beam clamps for permanent and temporary applications? Yes – beam clamps are ideal for quick jobs and mobile setups or as permanent fixtures in long-term structural installations, making them highly versatile, easy to adjust and compatible with a wide range of beam sizes.
TYPES OF BEAM CLAMPS
We know two of the types of beam clamps already – static and adjustable – but there are several more with different features to benefit different uses. Understanding the various types will help you choose the safest and most effective clamp for the job.
· Screw-type clamps:
These feature a threaded screw mechanism to tighten the clamp onto the beam flange. They have the advantage of easy installation, a very strong grip and are used for lifting applications. Some may see the manual adjustment as a downside due to it taking longer to reposition.
· Scissor clamps:
This type grips the beam through opposing force and self-tightens under load. Scissor beam clamps are fast to install and excellent for vertical lifting. On the downside, they offer less stability if not correctly aligned or loaded.
· Adjustable jaw clamps:
Similar to screw type clamps, adjustable jaw clamps have movable jaws that can be adapted to fit a range of beam widths. They’re versatile and perfect for multi-purpose and temporary use but may be more complex to set up compared to fixed versions.
· Fixed jaw clamps:
With non-movable jaws, these work best for consistent beam sizes and provide a highly secure grip. They are simple to install but lack the flexibility for varying beam widths.
· Application-specific clamps:
Some beam clamps are manufactured and designed for specific uses, such as pipe support, electrical conduit hanging or overhead lighting rigs. These are often integrated with gears and a chain, meaning the operator can more precisely move the load along the beam.
HOW TO USE BEAM CLAMPS
It’s important to understand how to use beam clamps safely and effectively, and the safe use will depend on the requirements for the lifting application. You should never use a beam clamp if you are uncertain of the load capacity or if the clamp has sustained any kind of damage.
Each installation will be different, so this is a general step-by-step guide on how to set them up and use them. If you ever need assistance on installing beam clamps, give the team at LES a call.
TOOLS REQUIRED
Typically, installation requires a wrench or socket set to tighten bolts, a torque wrench to ensure correct tension, as well as common tools like a measuring tape or spirit level for accurate alignment. Browse our range of tools to find the right solutions for use and installation.
STEP-BY-STEP INSTALLATION PROCESS
1. Inspect the clamp
Before use, check the beam clamp for signs of wear, corrosion, cracks or distortion. Ensure all moving parts operate smoothly and any locking mechanisms are functional. You should also inspect the beam where the clamp will be positioned.
2. Choose the right clamp for the job
Match the clamp to your beam size and the type of load. Use adjustable jaw clamps for variable beam widths, and make sure any application-specific requirements are met. If the clamp is not appropriate for the application, localised overloading will occur, leading to serious health and safety risks.
3. Position the clamp correctly
Secure the clamp over the beam flange, ensuring it is centred and level. The beam clamp needs to be positioned directly over the centre of gravity and must not be allowed to swing. Avoid misalignment that can lead to instability or slippage under load.
4. Tighten the clamp
Using the built-in screw or other locking mechanism, depending on the type of beam clamp used, tighten the clamp evenly until it is firm and has a secure grip. Be careful not to overtighten, as this could damage both the clamp and beam.
5. Test before use
Before jumping straight into using the clamp, apply a test load or manually check for movement. The clamp should remain stable, and the load path vertical and unobstructed.
There are several common errors to avoid when installing and using a beam clamp, including:
· Skipping inspections – all it takes is for one component of the clamp to be damaged to cause a serious risk of injury and damage
· Improper or uneven tightening – over-tightening can cause damage to the clamp and beam, and uneven tightening results in faulty movement
· Overloading beyond the rated capacity – this one’s a given, but NEVER overload the clamp beyond the rated capacity
· Using the wrong clamp – always check you have the right clamp, and if you’re unsure, consult the clamp’s specifications
You can expect most people to be able to install and use a beam clamp with ease.
FACTORS TO CONSIDER WHEN YOU’RE PURCHASING ONE
When buying a beam clamp, there are a few factors to consider before purchasing to ensure you have the right solution. These considerations can also form part of ideas that are specific to your business.
· Load capacity requirements:
It is imperative to always select a beam clamp with a rated load capacity that exceeds the maximum weight you plan to lift or support. Overloading can cause failure and serious safety risks. Luckily, beam clamps range in load capacity and weight, starting at 100kg and going up to 20,000kg.
· Beam flange size:
Ensure the clamp fits both the width and thickness of your beam flange. Measure accurately and choose a fixed or adjustable beam clamp accordingly.
· Clamp adjustability and compatibility:
If you’re working with different beam sizes or need flexibility for multiple applications, opt for an adjustable jaw clamp that offers a broader range of compatibility.
· Durability and corrosion resistance:
Look for clamps made from high-strength steel or alloy with corrosion-resistant coatings, especially for outdoor or industrial environments.
· Standards and certifications:
Check the clamp complies with relevant safety standards, such as BS EN 13155 and CE markings, ensuring it has been tested for structural integrity and safe lifting.
SAFETY MEASURES TO CONSIDER WHEN INSTALLING A BEAM CLAMP
Like you can expect in any industry, safety precautions for the operators and people in the area are a priority for businesses when installing equipment. These safety measures are to prevent accidents and damage at your workplace.
· Ensure your team, and anyone on site, do a thorough check before and after using this lifting solution to avoid any unnecessary accidents from occurring.
· Attach any suspending equipment to your beam clamp from a safety hook to avoid it from disconnecting.
· Ensure that you have the right version for the job. The different types of beam clamps have a different Working Load Limit (WLL).
· Make sure your product is compatible with other equipment you are using. Never force pieces of equipment to fit, as this may cause an accident. Use more than one clamp if deemed necessary.
· Ensure the beam is positioned over the centre of gravity of the hoisted load to avoid an unstable lifting procedure.
· Always adhere to applicable safety standards, such as OSHA regulations, LOLER (Lifting Operations and Lifting Equipment Regulations) and manufacturer-specific instructions.
· Installers and riggers should wear correct PPE and workwear, including hard hats, safety gloves, steel-toe boots, high-visibility clothing and safety googles or face shields.
· Only trained personnel should install and operate beam clamps and lifting gear. Supervision and double-checks should be part of the routine for every install and use.
