ABSTRACT:
There is provided a loader which is well suited for lifting heavy weight blocks and which is thus particularly advantageously usable in the assembling of blocks for building a ship. The loader body includes at least one beam arranged in a horizontal plane, and a plurality of separate pulley means are directly or indirectly mounted on the loader body in such a manner that these pulley means are arranged fixedly or movable to adjust the distance therebetween, whereby even when the center of gravity of a block is not in alignment with the center of the loader, the block can be lifted easily.
