The company name speaks for itself: D. Heinrichs Stauerei (Stevedores).

Stevedores ensure that cargo is loaded professionally on board a vessel. In 1859, the ship carpenter Dietrich Heinrichs  turned this into a profession and founded his own company. He closed a gap in the market: sailors used to cause havoc with the cargo on board their vessels – causing losses for both the owners of the cargo and the shipping companies.

Nowadays the stevedore is still the specialist, especially when it comes to unusual cargo.
