City Cranes
The city crane is a small 2-axle mobile crane which is designed to be utilized in tight areas where other cranes could not go. The city crane can work in between buildings and could travel through gates. In the 1990s, City cranes were developed as a solution to the growing urban density in the country of Japan. Lots of cities within Japan began building and cramming more structures in close proximity and it became necessary to have a crane that was capable of navigating through the small areas of Japanese roads.
City cranes are basically small rough terrain cranes. They are made to be road legal and are characterized by a single cab, a short chassis, a 2-axle design and independent steering on each axle. In addition, these types of machines offered a retractable slanted boom. This style of retractable boom takes up much less space than a horizontal boom of comparable size would.
Conventional Truck Crane
A mobile crane which has a lattice boom is a standard truck crane boom. This unit is lighter compared to the hydraulic truck crane boom. There are many boom parts which are able to 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 up and down, because it could not raise and lower using hydraulic power.
Kangaroo Crane

They are normally used in high-rise construction projects. Kangaroo cranes are unique within the business in the way that they could raise themselves as the building they are working on increases in height.
