City Cranes
The city crane is a small 2-axle mobile crane that is designed for use in compact areas where other cranes are not able to go. The city crane could work in between buildings and can travel through gates. During the 1990s, City cranes were developed as an answer to the growing urban density within Japan. Many cities within the country began building and cramming more structures near each other and it became necessary to have a crane which was capable of navigating through the small spaces of Japanese roads.
City cranes are essentially small rough terrain cranes. They are made to be road legal and are characterized by a single cab, a short chassis, independent steering on each axle, and a 2-axle design. Additionally, these machines offered a slanted retractable boom. This kind of retractable boom takes up much less space compared to a horizontal boom of similar size would.
