City Cranes
The city crane is a small 2-axle mobile crane which is designed to be used in compact areas where other cranes could not go. The city crane could work in between buildings and can travel through gates. In the 1990s, City cranes were developed as a solution to the increasing urban density in Japan. Numerous cities within the country began building and cramming more structures in close proximity and it became necessary to have a crane which was capable of navigating through the tiny spaces of Japanese streets.
City cranes are essentially small rough terrain cranes. They are made to be road legal and are characterized by a single cab, a short chassis, independent steering on each axle, and a 2-axle design. Additionally, these machinery provided a retractable slanted boom. This kind of retractable boom takes up much less space than a horizontal boom of the same size would.
Regular Truck Crane
Mobile cranes with a lattice boom are considered conventional truck crane booms. This model has a lighter hydraulic truck crane boom. There are many boom parts which could be added to enable the crane to reach over and up an obstacle. A typical truck crane requires separate power in order to move down and up, since it is not able to lower and raise using hydraulic power.
Kangaroo Crane
A jumping crane is a different name for a kangaroo crane. This unit is an articulated-jib slewing crane with an integrated bunker. These cranes started within Australia. They are often 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.
