Abstract: A cargo crane (1) for transferring containers (50) to and from a ship (100) birthed alongside a quay (110) is disclosed. The cargo crane (1) includes: at least one quayside support leg (10) supported by a bogie (60) arranged to travel on a rail, at least one landside support leg (20) supported by a bogie (60) arranged to travel on a rail, a boom (2) configured to extend over a ship (100) birthed alongside a quay (110), a trolley (3) displaceably connected to said boom (2), and container lifting means (5) connected to said trolley (3) The invention is novel and inventive in that said at least one quayside support leg (10) in a first height define an outer horizontal width (A) and, in a second height, said at least one quayside support leg (10) define an inner horizontal width (B?) wherein said inner horizontal width (B?) in said second height is greater or less than said outer horizontal width (A) of said quayside support leg (10) in said first height.
