City Cranes
The city crane is a small 2-axle mobile crane that is designed for use in compact areas where other cranes are not able to 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 city density in the nation of Japan. Numerous cities within the country began building and cramming more structures in close proximity and it became necessary to have a crane that can navigate through the small streets in Japan.
City cranes are essentially small rough terrain cranes. They are designed to be road legal and are characterized by a single cab, a short chassis, a 2-axle design and independent steering on each axle. Furthermore, these types of equipments offered a retractable slanted boom. This style of retractable boom takes up much less space compared to a horizontal boom of the same size would.
Typical Truck Crane
A mobile crane which has a lattice boom is a typical truck crane boom. This model is lighter compared to the boom on a hydraulic truck crane. There are many boom sections that are able to be added to enable the crane to reach over and up an obstacle. A regular truck crane requires separate power in order to move up and down, as 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 model is an articulated-jib slewing crane with an integrated bunker. These cranes originated within Australia. They are normally used in high-rise construction projects. Kangaroo cranes are different in the business in the way that they are capable of raising themselves while the building they are working on increases in height. These specific cranes are anchored by a long leg. This leg runs down the building's elevator shaft.
