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. During the 1990s, City cranes were developed as a solution to the increasing urban density within the country of Japan. A lot of cities within the nation started cramming and building more structures near each other and it became necessary to have a crane which could navigate through the small areas of Japanese roads.
City cranes are basically small rough terrain cranes. They are designed to be road legal and are characterized by a single cab, a short chassis, independent steering on each axle, and a 2-axle design. Moreover, these equipments offered a slanted retractable boom. This type of retractable boom takes up a lot less space than a horizontal boom of comparable size would.
