In 1913, German electrical apprentice C.A. Sievert established Oak Electric, which would later become SIevert Electric Services and Sales Company. Started out of a garage in the German neighborhood of Chicago, Oak Electric specialized in electrical motor repair.
At the start of World War 2, when everyone in the country focused on the war efforts, Oak Electric aquired machinery and began manufacturing their own motors. Up until this point they had continued to grow as an electric motor repair company and establishing themselves in the Chicago area.
Following World War 2 into the mid 1950's Oak Electric focused their efforts on the electrical motor repair and began doing more electrical work for the Chicago high rise boom. During this time Sievert became an industry staple in Chicago and was one of the main electrical contractors of the time.
Being a successful electrical contractor, Sievert decided to venture into the crane and hoist indutry, becoming the crane supplier for the Deep Tunnel Project underneath CHicago. Through the years Sievert has done projects in countries all over the world including Iraq, Argentina, Costa Rica and Angola in a variety of industries.
Today the crane and hoist division makes up 50% of Sievert and continues to provide crane and hoists all over the United States and the world.
