Shackle Lifting System

Another TAAG development boosts safety on site.

It is now common practice at TAAG to use lifting shackles for most lifts when erecting steel frame structures.

The process begins at the design stage where risks should be designed out if reasonably practicable to do so, as required by the Construction Design & Management Regulations 1994.

TAAG’s draughtsmen will calculate the centre of gravity of the element during design using our structural computer aided design software system.

This information along with other design elements will be downloaded to our C.N.C. cut and drill line, where the drilling of the lifting holes shall be completed along with other specific details of design, cutting, drilling, countersinking etc.

The shackle has a quick release mechanism, which allows safe erection of the steel elements and permits removal of the shackle by the erector at a remote position.

Two lifting shackles are used in two diagonally holes either side of the web which have been pre-drilled in the top flange of the steel beam. Not only does this give a tilt free lift, but provides a secondary safety system should either one of the shackles fail or in the very unlikely situation one is accidentally released.

Everyone is a winner when using the shackle erection system. The client benefits from an earlier delivery of the completed steelwork frame. The erectors benefit from an enhanced safety system decreasing at height erection time. The reputation of TAAG is increased with the HSE due to our commitment to Health and Safety.
