ABSTRACT:
Apparatus for for stacking papermaking pulp bales is disclosed, comprising two sets of lifting forks, which are directed towards each other for lifting bales, and a conveyor for inserting a new bale beneath the lifted bales. The lifting forks are horizontally movable between an advanced active lifting position and an inactive retracted position and have forward portions with a continuously decreasing thickness. The drive means for the lifting forks comprise a motor and a freewheel clutch for lifting and lowering the lifting forks, so that the lowering movement for both sets of lifting forks is automatically and individually adapted to their pulling-out movement when they rest on the underlying bale, although the speed of the drive motors which operate in a synchronized manner need not be controlled.
