ROTTEN TIMBERS COULD COME CRASHING DOWN

In 2013 a routine inspection of the structure and working parts of the cap identified the headframe timbers were badly rotten and it’s safety was in serious doubt. The principal timbers are two sheer beams that support the weight of the fantail platform, the sails, the weight of the machinery and the cap estimated in total to be 12 tons. And so something had to be done!

KEEPING THE HEADFRAME IN ONE PIECE

The main concern was that as the head frame was lifted by a crane the rotten timbers may collapse under its own weight.  Ideally the head frame was required intact at ground level so it could be used as a pattern for it’s replacement.  To achieve this the large visible cracks in the timbers were filled with cement and a long ‘rolled steel joist’ (RSJ), was strapped to each sheer beam.

RENOVATING THE HEADFRAME

The reinforcement of the concrete infill and RSJs was successful and the headframe was successfully lifted down and placed on a frame to provide a safe working environment for it’s restoration.
