Work positioning or rope access as it is often referred to is a method of accessing a building or structure by means of a rope system. The important point with work positioning is the user must have a back-up at all time while suspended. This applies also to the eyebolts. There should never be a time where a person is suspended from a single eyebolt.
As specialist rope access contractors we have a huge amount of experience in the placement and positioning of eyebolts in this field. The eyebolts are always placed in pairs for use by one person, however in the event of rescue it would be possible to have 2 persons suspended from the eyebolts.
A knurled threaded sleeve is secured into the structure with a two-part resin system. Once cured an eyebolt is screwed into the insert to the required torque setting. The anchor is then tested by attempting to pull it back out of the structure in the direction it went in. Work positioning eyebolts can also be installed in structural steel.
When combined the eyebolts must be able to take a load of 15Kn (1500Kg). Once installed the anchor will have a calibrated test rig set up on it and the anchors tested to the relevant force.
Once the installer has carried out all the testing and inspection, certification will be issued for the use of the eyebolts.
As the eyebolts are going to be used to suspend a load (a person is classed as a load) they are tested and inspected under the Lifting operations & Lifting equipment Regulations (LOLER) 1998. The eyebolts must be inspected and tested on a 6 monthly basis by a competent person.
