City Cranes
The city crane is a small 2-axle mobile crane which is designed to be utilized in compact areas 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 a solution to the increasing urban density within the country of Japan. A lot of cities in the nation started cramming and building more structures in close proximity and it became necessary to have a crane which was capable of navigating through the tiny roads in Japan.
City cranes are basically small rough terrain cranes. They are made to be road legal and are characterized by a short chassis, a single cab, a 2-axle design and independent steering on each axle. Furthermore, these types of equipments offered a retractable slanted boom. This kind of retractable boom takes up a lot less space than a horizontal boom of comparable size would.
