City Cranes
A small 2-axle mobile crane, known as a City crane is designed for use within compact spaces where the regular cranes could not venture. City cranes are used to work within buildings or to travel through gates. During the 1990s, City cranes were developed as an answer to the increasing city density within Japan. Lots of cities within the country began building and cramming more structures near each other and it became necessary to have a crane which could navigate through the small spaces of Japanese roads.

This crane is designed to be road legal and is characterized by a single cab, a short chassis, independent axle steering, and the 2-axle design. Moreover, these equipments offered a retractable slanted boom. This kind of retractable boom takes up a lot less space compared to a horizontal boom of similar size would.
Conventional Truck Crane
