A view from above - lifting a concrete girder
A view of the setup on top of the Pearman approach: A hammer, a shear and
three guys (Paul, Jackie and I forgot)
Coupling the hoisting cables to the concrete girder - the two lower guys
are in a man basket from below.
A bit of burn surgery - cutting through the attachments at the far end
Then Jackie Using the shear to lift one end of the girder
Jackie and a bit of surgery here - gently lifiting one end of the girder
With the crane taking up the slack, Jack eases the shear grip and backs
away
and the crane lifts - (I stitched a short video of the action
click for video (6 Mb))
and lifts
and lifts
and now lowers the girder
down and down and down
until all that is left is the ghost of the pearman and a couple more girders
