At the start of the graveyard shift at approx. 10:40 p.m. the 19 member crew loaded onto the mancage. As the mancage was being lowered the pinion emergency brake lost hydraulic oil pressure and the brake set. The mancage and crew were trapped in the shaft until 11:25 p.m. when the emergency brake was released and the crew was brought back to the surface.
