Seagoing vessel to sledge:

unloading

Classical harbors featured quays constructed with materials like blocks, ashlar masonry, and structural concrete, allowing the creation of docks in various locations regardless of natural geographical features. These quays served as hubs for harbor operations and also provided the infrastructure needed for transferring large shafts from ships onto sledges.

In the depicted scenario, these wooden structure resembles ancient harbor treadwheel cranes that extended over the water's edge, facilitating the transfer of goods from quay to vessel. While the specific wooden structure is secondary, it serves as a framework for Francesco's machines. The machines chosen for this operation include a device for lifting columns and two winches for horizontal movement toward the sledge.

The lifting device's connection resembles a scissor-like hook designed for columns, offering durability and ease of removal. Winches are employed to move the column horizontally toward the sledge while lowering it. Coordination between operators is crucial for this method, ensuring a smooth transition of the column onto the sled for its overland journey to the construction site.
