An apparatus for discharging loose particulate solid material from a storage space, for instance the hold of a ship. A screw conveyor is suspended in a carriage mounted at the upper part of the space and is horizontally movable. The carriage has a hoisting machinery for wire ropes in which a beam is suspended along which the conveyor is mounted. At least two stabilizing wire ropes are secured to the beam and run to pulleys on the carriage, which pulleys are so disposed that the wire ropes cross each other at a point between the carriage and the beam. From the pulleys stabilizing wire ropes run to a device for keeping the wire ropes tensioned when the beam is raised, lowered and stationary. |
