Beam Clamps Explained: Types, Uses and How to Choose

SecureHeights Beam Anchors: Fixed, Sliding and Trolley Options

SecureHeights offers a range of purpose-designed beam anchors for fall protection applications on compatible structural steelwork. The selection includes fixed beam anchors for stationary anchorage, sliding models that can travel along a suitable beam, and trolley designs for applications requiring regular horizontal movement. The examples below illustrate several available configurations, but the appropriate beam anchor should always be selected according to the intended application, beam dimensions and profile, permitted loading, user requirements and manufacturer instructions.

Skylotec BEAMTAC 2.0 9cm-36cm Fixed Beam Anchor AP-075

(The Skylotec BEAMTAC 2.0 AP-075 is an aluminium beam anchoring device designed for attachment to suitable steel beams with flange widths from 90 to 360 mm. Its adjustable clamping jaws allow the device to be fitted and repositioned without permanent modification to the supporting steelwork, while a multi-level safety system is designed to help prevent unintended movement or slipping during use. Weighing 2.32 kg, the BEAMTAC 2.0 is suitable for industrial, steel construction and rope access applications and is rated for use by up to two people, subject to the manufacturer's requirements and the suitability of the supporting structure. It is specified to EN 795:2012 Type B and CEN/TS 16415:2013, as well as ANSI/ASSP Z359.18-2017).

Kaya Safety Beam Trolley BTA012N

(The Kaya Safety Beam Trolley BTA012N is a mobile beam anchor designed to travel along suitable structural I-beams as part of a personal fall arrest system. Its adjustable rollers accommodate beam widths from 76 to 255 mm and flange thicknesses up to 23 mm, while toggle plates simplify adjustment during installation and removal without requiring drilling or other alteration to the beam surface. The lightweight aluminium body weighs 1.5 kg and incorporates a steel swivel D-ring as the anchorage point. Designed for a maximum of one user, the BTA012N has a stated safe working load of 140 kg and minimum breaking strength of 22 kN, and is specified to EN 795:2012 Type B alongside the listed OSHA and ANSI requirements. Importantly, this beam trolley is intended for fall protection and is not suitable for material handling).

3M DBI-SALA Adjustable Trolley i-Beam Anchor 7.6cm-20.3cm 2103148

(The 3M DBI-SALA Adjustable Trolley i-Beam Anchor 2103148 is a mobile anchorage device designed to travel along a compatible structural I-beam, providing an anchorage point that can move with the user during work at height. The adjustable trolley accommodates beam widths from 7.6 to 20.3 cm and a stated steel thickness of 1.7 cm, allowing it to be configured for suitable beam profiles within these dimensions. This trolley arrangement can be particularly useful where regular horizontal movement along structural steelwork is required and a stationary beam anchor would unnecessarily restrict the working area. The unit weighs 6.8 kg. As with any mobile beam anchor, selection should consider more than beam width alone: the beam profile, flange thickness, installation arrangement, travel path and complete fall protection system should all be checked against the manufacturer's requirements before use).

3M DBI SALA Fixed Beam Anchor

(The 3M DBI-SALA Fixed Beam Anchor is a portable anchorage connector designed to provide a fixed connection point on compatible structural steel for personal fall protection systems. Constructed from high-strength steel and aluminium, it has a stated overall strength of 22 kN and user capacity of 189 kg, with several versions available for different beam dimensions. A detent-style adjustment system with an integrated tightening handle supports straightforward installation, while the built-in swivelling D-ring provides the designated connection point for compatible equipment such as a lanyard or self-retracting lifeline. According to the manufacturer, the anchor can also be used in specified horizontal lifeline configurations and installed in different orientations, provided the selected model, supporting structure and complete fall protection arrangement meet the applicable instructions and requirements).

3M DBI SALA Glyder Sliding Beam Anchor 2104704

(The 3M DBI-SALA Glyder Sliding Beam Anchor 2104704 is a mobile anchorage connector designed to move along a compatible structural beam as the user changes position. It accommodates beam flanges from 90 to 355 mm wide and up to 32 mm thick, with a dual ratcheting adjustment system that allows the anchor to be fitted closely to the flange. The rotating D-ring provides a connection point for a compatible lanyard or self-retracting lifeline, while a guarded locking mechanism helps reduce the risk of accidental disengagement. Replaceable wear pads minimise metal-to-metal contact, and the corrosion-resistant construction is intended for demanding environments such as construction sites, bridges and industrial buildings. Weighing 2.04 kg, the anchor has a stated strength of 22 kN and capacity of up to 189 kg, and is specified by the manufacturer as meeting the listed ANSI and OSHA requirements).

The products above demonstrate how beam anchor designs can differ considerably in their adjustment ranges, movement characteristics and intended applications. When comparing individual models, consider the complete specification rather than selecting an anchor solely by type or price. Beam compatibility, supporting structure, required mobility and integration with the wider fall protection system should all be confirmed before use.

Beam Clamp vs Beam Anchor: What Is the Difference?

The distinction between beam clamp vs beam anchor is mainly one of function and intended use. Beam clamp is a broad term describing equipment that mechanically engages with a beam. Such clamps can be used for lifting, building services, structural attachments and other applications.

A beam anchor describes a device whose purpose is to provide an anchorage. In work at height, a fall protection beam anchor is specifically intended to form part of a personal fall protection system. Some beam anchors use a clamping mechanism, which explains why the terms sometimes overlap, but they should not be treated as interchangeable.

The difference is particularly important when comparing lifting equipment with fall protection equipment:

• lifting beam clamps are designed for material lifting or suspension within specified working load limits and loading conditions;

• fall arrest beam anchors are designed for personal protection and must account for the loads and system conditions associated with their intended use;

• permissible loading directions may differ between products;

• a lifting clamp's WLL does not demonstrate suitability for fall arrest;

• connections to harnesses, lanyards, self-retracting lifelines or other fall protection equipment must comply with the anchor manufacturer's instructions;

• the supporting beam must also be suitable for the loads that the complete system can impose.

A fall arrest beam clamp should therefore never be selected solely because its dimensions fit the beam or its lifting capacity appears sufficient. Only a beam anchor intended and specified for personal fall protection should be used for that purpose.

Benefits of Beam Clamps and Beam Anchors

Purpose-designed beam anchors offer several practical advantages where suitable structural steelwork is available. In appropriate applications, they can create an anchorage without drilling or welding the beam, which can avoid unnecessary permanent modification of the structure.

Other potential benefits include:

• relatively quick installation and removal;

• repositioning between suitable work locations;

• adjustable designs covering a specified range of flange dimensions;

• fixed and mobile configurations for different working patterns;

• portable solutions for temporary maintenance, inspection and construction activities;

• use of suitable existing structural steelwork rather than installing a permanent anchorage solely for a short-duration task.

These advantages do not apply equally to every beam anchor. A temporary beam anchor or portable beam anchor still has to be compatible with the structure, intended loading conditions and complete fall protection system. The convenience of an adjustable steel beam anchor should never take precedence over correct specification and installation.

How to Choose a Beam Clamp or Beam Anchor

Knowing how to choose a beam clamp starts with the application, not simply the dimensions of the steelwork. For personal protection, the selected device must be intended for the relevant work-at-height use and compatible with both the supporting structure and the complete system.

The main factors to assess are:

• Intended application. Establish whether the connection is required for building services, material lifting, restraint, fall arrest or another work-at-height application. Equipment intended for one purpose should not be assumed suitable for another.

• Beam width, flange thickness and profile. Check the flange width and thickness, beam profile, permitted adjustment range and installation position against the manufacturer's specification. An adjustable beam clamp may physically fit an I-beam while still being incompatible with its flange geometry or intended installation. The same principle applies when selecting an I beam anchor.

• Required movement. A fixed anchor can suit stationary work within a defined area, while a sliding design can accommodate horizontal movement along an appropriate beam. A trolley anchor may be preferable where regular travel is required. The selected configuration should support the planned movement without encouraging unsafe positioning or disconnection.

• Rated capacity and number of users. Check the ratings and maximum number of users specified for the particular device. Beam clamp load capacity for lifting equipment and the performance requirements of a personal fall protection anchor are not directly interchangeable, so a lifting WLL should not be used as the basis for selecting a fall protection device.

• Direction of loading. Determine how forces could be applied during use and whether the manufacturer permits that loading direction. Vertical, angled and side loading may be treated differently between products. Multidirectional loading must never be assumed unless specifically permitted.

• Supporting structure. The rating of a beam anchor does not establish the capacity of the beam to which it is fitted. The structural steelwork and its supporting structure must be capable of resisting the loads associated with the intended system and installation.

• Environment and material. Consider moisture, corrosion, chemical exposure, temperature and the condition of the structural steel. Environmental conditions can affect both the steel beam anchor and the structure throughout their period of use.

How to choose a beam anchor therefore depends on several connected factors. Beam dimensions establish only part of compatibility. Intended use, movement, loading, structure, environment and the manufacturer's limitations must be considered together.

SecureHeights Comment: When selecting a beam anchor for fall protection, do not rely on flange width or rated capacity alone. Check the complete manufacturer specification against the beam profile, intended loading, number of users and required movement, as well as the suitability of the supporting structure. If there is uncertainty about compatibility, it should be resolved before the equipment is put into service.

Beam Anchors vs Alternative Anchorage Methods

Beam anchorage is one of several ways to create a fall protection anchor point, and it is not automatically the most appropriate solution whenever structural steel is available. Alternatives include permanent fixed anchors, anchorage straps or strops, counterweight systems, vacuum anchors and engineered horizontal lifeline systems.

A temporary beam anchor can be particularly useful where suitable steelwork is accessible and permanent modification is unnecessary or undesirable. An anchorage strap may offer a simpler solution around an appropriate structural member, while counterweight or vacuum systems can address particular surfaces and locations where conventional structural attachment is impractical. For work requiring continuous movement across a larger area, an engineered horizontal lifeline may provide a more appropriate access strategy than an individual beam anchorage point.

Selection should be based on the structure, task duration, required mobility, installation constraints and overall fall protection strategy rather than on the convenience of a single anchor type.

How to Install a Beam Clamp or Beam Anchor Safely

Beam anchor installation should always follow the instructions for the specific product. There is no universal installation procedure or tightening value that applies to every design.

Key steps include:

• Check the beam and anchor before installation. Confirm the beam dimensions, flange geometry, installation position and condition of the steelwork. Inspect the anchor for damage, corrosion, deformation and missing components, and make sure identification and markings remain legible. Verify that the particular device is compatible with the beam rather than relying on visual fit alone.

• Position and adjust the anchor. Install the device in its permitted orientation and ensure the jaws or other engagement components are correctly positioned on the flange. Adjustment and locking mechanisms should be fully engaged as specified by the manufacturer. Do not improvise with spacers or modifications to make an unsuitable anchor fit.

• Connect the fall protection system. Use the designated attachment point and compatible connectors. The lanyard, self-retracting lifeline or other connecting equipment should be attached in the permitted orientation, with connector loading and potential interference considered. Knowing how to use a beam clamp safely means considering the complete system, including clearance and the user's working position.

• Check mobile anchors. Sliding and trolley devices should move freely across their permitted travel area. Check for obstructions, beam joints, end conditions or structural features that could prevent movement or cause the device to disengage or operate incorrectly.

A final functional and visual check should be completed before the equipment is placed into use.

Beam Clamp and Beam Anchor Inspection and Maintenance

Beam clamp inspection helps identify damage or deterioration that could affect secure attachment or operation. Pre-use checks should be appropriate to the equipment and follow the manufacturer's instructions.

Depending on the design, a beam anchor inspection should consider:

• deformation, cracks, corrosion and excessive wear;

• condition of jaws and beam-contact surfaces;

• threads and adjustment mechanisms;

• locking components and fasteners;

• designated attachment points;

• rollers or wheels on trolley designs;

• identification and safety markings;

• evidence of overloading, impact or other abnormal loading;

• unauthorised modifications or replacement components.

Equipment should also receive any further examination, servicing and maintenance required by its intended use, applicable requirements and manufacturer's instructions. Equipment that has arrested a fall, is damaged or raises doubt about its condition should be withdrawn from use and dealt with in accordance with the manufacturer's procedure rather than simply returned to service after a visual check.

In the UK, the Work at Height Regulations 2005 require work equipment used for work at height to be appropriate for the work and address inspection in specified circumstances. Other legislation may apply depending on how equipment is used. LOLER should not, however, be presented as automatically applying to every fall protection beam anchor simply because the device attaches to a beam.

Common Beam Clamp and Beam Anchor Mistakes

Beam anchor safety depends as much on correct selection and use as on the condition of the device itself. Many problems arise when one specification, such as flange width or a stated capacity, is considered in isolation.

Common mistakes include:

• selecting a clamp simply because it fits the beam width;

• using a lifting beam clamp for personal fall protection without it being intended for that purpose;

• ignoring flange thickness, profile or permitted installation position;

• exceeding the specified number of users;

• attaching a fall protection beam anchor to unsuitable structural steelwork;

• assuming that angled or side loading is permitted;

• installing the device in an incorrect orientation;

• connecting equipment somewhere other than the designated attachment point;

• using an incompatible or incorrectly loaded connector;

• failing to account for the required fall clearance or potential swing fall;

• allowing joints, obstructions or end conditions to interfere with a sliding or trolley anchor;

• continuing to use damaged, modified or excessively worn equipment;

• using equipment with identification or safety markings that can no longer be read;

• neglecting beam clamp inspection or disregarding the manufacturer's instructions.

Correct selection starts with the intended application. Beam compatibility can then be assessed alongside anchor type, permitted loading, required movement and environmental conditions.

For personal fall protection, the assessment must extend beyond the anchor itself. The supporting structure, connectors, lanyard or self-retracting lifeline, available clearance and intended movement all form part of the system. A suitable beam anchor is therefore one component of a properly planned fall protection arrangement, not a substitute for considering the system as a whole.

SecureHeights Comment: One of the most important distinctions is between equipment designed for material handling and equipment intended for personal fall protection. A beam clamp that appears suitable mechanically, or carries a substantial lifting rating, should not be treated as a fall protection beam anchor unless the manufacturer specifically permits that application. Always select and use the device according to its stated purpose and instructions.

Choosing the Right Beam Anchor for Work at Height

Beam clamps cover a broad range of equipment, so correct selection always begins with the intended application. For fall protection, a purpose-designed beam anchor must be suitable for the particular beam dimensions and profile, permitted loading direction, number of users and required movement. The supporting structure and the rest of the fall protection system must also be considered. A device that simply clamps securely to structural steel should never be assumed suitable for fall restraint or fall arrest.

SecureHeights supplies a range of fall protection beam anchors for structural steelwork, including fixed, sliding and trolley designs from established height-safety manufacturers. The available options allow equipment to be selected according to beam compatibility, working position and the level of horizontal movement required. When choosing a fall protection beam anchor, always check the individual product specification and manufacturer instructions to confirm that the device is appropriate for the intended application and forms part of a properly planned work-at-height system.
