City Cranes
The city crane is a small 2-axle mobile crane that is designed for use in compact spaces where other cranes could not go. The city crane can work in between buildings and can travel through gates. In the 1990s, City cranes were developed as an answer to the increasing city density within the nation of Japan. Lots of cities within Japan started cramming and building more structures near each other and it became necessary to have a crane which was capable of navigating through the small roads in Japan.
Basically, the city crane is a small rough terrain crane. This crane is made to be road legal and is characterized by a single cab, a short chassis, the 2-axle design and independent steering on each axle. In addition, these equipments offered a retractable slanted boom. This style of retractable boom takes up much less space than a horizontal boom of similar size would.
Standard Truck Crane

There are many boom sections that could be added to allow the crane to reach up and over an obstacle. A conventional truck crane requires separate power to be able to move down and up, since it could not lower and raise using hydraulic power.
