City Cranes
A small 2-axle mobile crane, referred to as a City crane is designed to be used within compact spaces where the regular cranes could not venture. City cranes are used to work within buildings or to travel through gates. In the 1990s, City cranes were developed as a solution to the increasing city density within Japan.
