Aliko Dangote, Africa's richest man, has achieved success through determination and perseverance. After starting his business career in 1978, he expanded into manufacturing and founded the Dangote Group, which operates in 17 African countries and is a leader in the cement market.

Dangote Cement Plc, a subsidiary of the group, is the largest listed company in West Africa and the first Nigerian company to join the Forbes Global 2000 Companies list. 

The group also includes Dangote Sugar Refinery and NASCON Allied Industries. Dangote's latest project, the Dangote Petroleum Refinery and Petrochemicals, located in Lagos, is one of the few petroleum refineries and petrochemical complexes in the world to be executed directly as an Engineering, Procurement, and Construction (EPC) contract by an individual owner.

However, the construction of the refinery faced significant challenges, including difficulties in clearing imported consignments and the limitations of the port's capacity to handle heavy equipment.

Even after succeeding in bringing the equipment in, on which road would you transport them?

What do you do when the biggest crane in the country is 650 tons, whereas you need a 5000-ton capacity crane?

Worse, there were only two such 5000-ton capacity cranes in the world, and they were in use.

So, instead of hiring a crane for $300,000 a day, what do you do?  Dangote bought his cranes.

There are a lot of over-dimensional cargoes like the heaters and pipes, so, Dangote had to sign a contract with a company to do the transportation into its yard and had to pay over $70 million just for that.
