Abstract
1,238,862. Face shovel excavators. IZHORSKY ZAVOD IM. ZHDANOVA. 10 July, 1968, No. 32905/68. Heading E1F. The centre bight of the hoist cable of a face shovel excavator passes about a sheave 10 resiliently mounted on the excavator's boom before passing up and about pulleys of sheaves at the free end of the boom, down and about pulleys 6, 7 secured to the shovel or shovelcarrying arm of the excavator and then up and about further pulleys of the boom end-supported sheaves before being secured to winch drums of the excavator. The pulleys 6, 7 are mounted about a common axis disposed at right angles to the longitudinal axis of the shovel-carrying arm. The dipper stick is so mounted on the boom that the dipper stick can be rotated about its longitudinal axis and about an axis at right angles thereto.
