City Cranes
The city crane is a small 2-axle mobile crane which is designed to be used in compact areas 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 growing city density within the country of Japan. Numerous cities in Japan started cramming and building more structures near each other and it became necessary to have a crane that could navigate through the small spaces of Japanese streets.
Essentially, the city crane is a small rough terrain crane. This crane is designed to be road legal and is characterized by a short chassis, a single cab, the 2-axle design and independent steering on each axle. Moreover, these machines provided a retractable slanted boom. This type of retractable boom takes up much less space compared to a horizontal boom of similar size would.
Typical Truck Crane
Mobile cranes with a lattice boom are considered standard truck crane booms. This unit has a lighter hydraulic truck crane boom. There are multiple boom parts that could be added to enable the crane to reach up and over an obstacle. A standard truck crane requires separate power to be able to move down and up, because it is not able to raise and lower with hydraulic power.
Kangaroo Crane

They are normally utilized in high-rise construction projects. Kangaroo cranes are unique within the business in the way that they could raise themselves while the building they are working on increases in height. These particular cranes are anchored using a long leg. This leg runs down an elevator shaft of the building they are constructing.
