City Cranes
A small 2-axle mobile crane, referred to as a City crane is designed to be utilized in tight areas where the usual cranes are unable to venture. City cranes are utilized to work in buildings or to travel through gates. During the 1990s, City cranes were developed as a solution to the growing city density within Japan. Numerous cities within Japan began building and cramming more structures near each other and it became necessary to have a crane that was capable of navigating through the tiny spaces of Japanese roads.

This crane is designed to be road legal and is characterized by a short chassis, a single cab, independent axle steering, and the 2-axle design. Additionally, these types of machines offered a slanted retractable boom. This kind of retractable boom takes up much less space compared to a horizontal boom of comparable size would.
Typical Truck Crane

A typical truck crane requires separate power in order to move up and down, because it could not lower and raise using hydraulic power.
Kangaroo Crane
A jumping crane or a kangaroo crane is a articulated-jib slewing crane that is designed with an integrated bunker. These cranes were initially developed in Australia. They are usually utilized in high-rise construction projects. Kangaroo cranes are unique within the industry in the way that they can raise themselves as the building they are working on increases in height. These particular cranes are anchored by a long leg. This leg runs down the building's elevator shaft.
