Hanckes was the son of the brickworks owner Hinrich Hanckes and his wife Anna Margaretha Hanckes geb. Behling. He graduated from high school and then from the Hanover Polytechnic . After completing his studies, he worked for the port building authority in Bremerhaven from the beginning of the 1850s. After passing the state examination in 1863, he was appointed construction manager 1st class . He was involved in the expansion of the new port planned by Jacobus Johannes van Ronzelen and in the expansion of the sewer system in Bremerhaven. In 1864/65 he became the planner and site manager for the dry dock of the Ulrich an der Geeste company . In 1870/71 he created the plans for the old double dry dock for North German Lloyd (today Gustav W. Rogge) in Bremerhaven.
