City Cranes
The city crane is a small 2-axle mobile crane which is designed to be utilized in tight spaces where other cranes are not able to go. The city crane could work in between buildings and can travel through gates. In the 1990s, City cranes were developed as an answer to the growing urban density within Japan. Many cities in Japan began cramming and building more structures near each other and it became necessary to have a crane that was capable of navigating through the small streets in Japan.
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 retractable slanted boom. This type of retractable boom takes up much less space compared to a horizontal boom of similar size would.
