Reachstacker - Large vehicle designed to pick up and carry full-sized containers around a container yard. Reachstackers have different sizes, and may have maximum load limits under a fully loaded container. Reachstackers are usually not used for offloading vessels, unless the the vessels are small and in in unimproved port conditions - they are mostly used for rearranging containers in a shipping yard, or loading containers onto truck bodies for onward movement. 

Shipside Container Crane - A large crane capable of offloading full-sized containers directly from the deck of a ship. Shipside container cranes may either be stationary, or capable of moving to meet the needs of the operation. The cranes are usually very tall - well above the decks of most vessels rated for that port and are capable of lifting loads up to the max weight of containers. 

Gantry Crane - Another form of moveable container crane, one that specifically straddles both side of a vessel or stack. Gantry cranes can be large enough to reach over the deck of an entire vessel, but may also be used for loading and offloading trucks or piles of cargo. 

Unloader / Grain Vacuum - A specialized tool for offloading loose, bulk cargo such as grain or sand with an extended adjustable arm that reaches into the deck of a bulk carrier. Unloaders can have a mechanical function, scooping and lifting bulk cargo like an elevator inside the arm. There are also configurations where the arm is a giant vacuum for grains called a "grain vac", that pushes loose grain out the back to a pre-set destination. 

Ship with Deck Mounted Cranes - Some ships may require their own onboard mounted MHE, such as deck mounted cranes. On-board MHE helps alleviate the problem of working within ports that have limited handling equipment.

Grain Conveyor - A large mechanical conveyor that can either lift and dump grain, or be used to slowly offload grain from the belly of a bulk carrier. If used for offloading, there is usually a bagging operation occurring at the receiving end.
