[Tech1] Any Information on Vinten pedestals etc gratefully received!

[Graeme Wall]

On the subject of cranes, the Mole had a 1:1 arm but the Nike was a 2:1 arm necessitating double the amount of lead in the bucket to balance the camera and cameraman on the other end.  IIRC the Atlantic was the same.

Somewhere I Ihave a GTC booklet on camera cranes, if I can find it I’ll scan it and email it to you.

So any information on that would be gratefully received (as would any drawings, e.g. a GA).  I am guessing that a similar arrangement was used to balance the crane arm in the Vinten Heron - or was it?

What other things should I consider?  Stringing on the Mole Boom, for instance how many pulleys ...
