Safety Eyebolts
Specialist safety eyebolts available in mild Steel or stainless steel construction. Mild steel product available in zinc plated, Galvanised or white coated finish.
Supplied, designed and installed to EN795 class A Standard.
Anchors fixed into masonry are screwed into Knurled sockets that are resin fixed in place then site pull tested to 6kN force.
The fixing position is crucial to ensure adequate support from the surrounding structure also to minimise the potential fall distances in the event of a fall. Therefore the installation of safety eyebolts must be carried out by specialist installers such as Harcon services limited.
Their positioning should always be determined by a competent person, following the recommendations of BS 7883:1997 clause 8 where appropriate.
Installation should also follow Appendix A of EN 795 and also BS 7883, and must always include testing procedures detailed in the appropriate clauses of those standards. Never use eyebolts, other than EN 795, as Fall Arrest Anchor Devices – the wrong eyebolts in the wrong situation could prove Fatal.
Our safety eyebolts for use in brick, concrete and masonry have a 16mm diameter unthreaded shank to ‘plug’ a drilled hole, thus reducing the bending effects which would result in earlier failure during shear loading.
These safety eyebolts can be used by fixing to an outside or inside face of a structural element adjacent to the window or other access.
They are manufactured from either high tensile carbon steel with a galvanised or plastic-coated finish, or grade 316 stainless steel bright polished.
Typical Examples
Standard 100mm Eyebolt. For use with knurled insert in brick, Concrete and masonry etc. as per figures 7 and 8 of BS 7883:1997
Longer 152mm Eyebolt. Available where deeper fixing is necessary.
75mm Shank Length. For use ONLY on steel structures. See BS 7883:1997
Periodic Inspection.
BS 7883 requires that all safety anchor devices are removable for periodic inspection. This is easily achieved by using Knurled inserts in conjunction with suitable resin compounds.
PPE Warning Disc
These are required to comply with Appendix ‘A’ of EN 795 which states:
“Where an anchor device is intended to be used exclusively for personal protective equipment it should be clearly marked by pictogram or other clearly seen and understood marking on or near the anchor device, clearly stating that the device is designed exclusively for use of personal protective equipment”.
Cantilever Anchor Devices.
For use in dry lined walls or in conjunction with plasterboard, cladding etc.
In situations where the anchor device is required to protrude beyond the surface of the load bearing structure, it is essential that appropriate resistance to bending be incorporated into the installation.
Spacer Sleeves.
Where the distance from the face of the load bearing structure to the collar of the eyebolt does not exceed 25mm, a spacer sleeve may be placed under the eyebolt collar to provide the necessary support.
Criteria for their use.
Use only in conjunction with 100mm (or longer) RINGANKA anchor devices, designed for use in brick, stone or concrete etc.
Do not use in conjunction with anchor devices which are threaded to within 50mm of the collar.
Use only in conjunction with resin bonded knurled inserts of at least 100mm overall length.
Knurled inserts to be resin bonded at least 50mm below surface of load bearing structure.
Spacer sleeve must pass through cladding, plaster etc, and be in direct contact with the load bearing structure.
Cantilever sockets.
Where the distance from the face of the load bearing structure to the collar of the eyebolt exceeds 25mm, special cantilever sockets are available. Where the distance to be bridged exceeds 160mm, (120mm in brick) special advice should be sought.
Criteria for their use.
The socket must be embedded (and bonded) for a minimum length of 120mm into the load bearing structure. (150mm in brick).
The eyebolt must not protrude more than 160mm from the surface of the load bearing structure. (120mm in brick).
Installation requires a 38mm diameter hole to be drilled through the cladding and into the load bearing structure to a depth of at least 10mm more than the embedment.
General requirements for Cantilever anchor devices.
Maximum permitted in-service force = 6kN (design capability = 10kN as per EN 795) i.e. all users must be protected by the provision of an energy absorber to EN 355
Load bearing structures and chemical fixings must be capable of withstanding a 10kN pull-out force.
Each individual installed anchor device must be subjected to a 5kN pull-out force (as per EN 795 Appendix B, and BS 7883).
It should be noted that, when installed into materials of less than 20N/m compressive strength, there may be local crushing/compacting around the drilled hole at fall arrest.
