Abstract
A general cargo crane for unloading general cargo from a ship's hold, in particular general cargo placed on a pallet, comprises a continuously operating conveyor in a shaft of which at least the bottom part is vertically displaceable. To solve the problem how general cargo can be introduced into the continuously operating conveyor smoothly and with a minimum of manpower, provision is made at the lower end of the shaft (4) for a cage-type frame (15) which is provided at least one side with a deposit platform (16a, 16b) and lifting elements (17, 18) for moving the deposit platform between a lower position in which general cargo can be deposited on the platform and a higher position in which the general cargo can be transferred to the continuously operating conveyor. The cage is provided with a fixed transfer platform (19) at the level of the higher position of the deposit platform, wherein sliding plates (21-26) are present for transferring general cargo standing on the deposit platform in the higher position thereof onto the transfer platform and a push arm is present ( 28, 29) for transferring general cargo standing on the transfer platform from the transfer platform to the continuously operating conveyor.
