Lifting aid

Background

The Olympic Stadium bowl design involved installation of concrete pre-cast steps providing access corridors to the terraces. In addition, the stadium roof support system relied on heavy cabling that needed to be moved into position.

Hazard

Manual handling of the heavy pre-cast concrete units and the roof support cables involved significant risk of musculoskeletal disorders (MSD).

Solution

A simple lifting device was manufactured to allow both the pre-cast units and the cables to be lifted safely and easily. It worked by using a simple fulcrum action which significantly reduced the human force required to lift both items.

The first design (photo 1) of the lifting arm was used exclusively for the pre-cast concrete units.

The construction team soon realised that the same engineering solution could be adopted to to assist in lifting and placing the roof support cables (photo 2).

The lifting aid was designed with wheels to allow it to be easily and safely used and moved around the site.
