In the pit were two hanging cradles designed to hold the 40 cast iron weights, 1/2 cwt. each, (56 pounds or 25 kg) we are still doing the reverse engineering on the Jamison installation to calculate how much mass was needed to tension the track ropes. The mine end of the Gladstone installation would not have needed much mass, but the tension station between the drive and the unload station would need much more.
