City Cranes
The city crane is a small 2-axle mobile crane that is designed to be utilized in compact areas where other cranes could not go. The city crane could work in between buildings and could travel through gates. In the 1990s, City cranes were developed as an answer to the growing urban density in the country of Japan. A lot of cities within the country began cramming and building 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 designed to be road legal and are characterized by a short chassis, a single cab, independent steering on each axle, and a 2-axle design. Furthermore, 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 the same size would.
Standard Truck Crane
Mobile cranes with a lattice boom are considered typical truck crane booms. This unit has a lighter hydraulic truck crane boom. There are many boom parts that could be added to enable the crane to reach over and up an obstacle. A conventional truck crane needs separate power to be able to move down and up, since it could not raise and lower using hydraulic power.
Kangaroo Crane
A jumping crane or a kangaroo crane is a articulated-jib slewing crane which is designed with an integrated bunker. These cranes were initially developed within Australia. They are often used in high-rise construction projects. Kangaroo cranes are different within the industry in the way that they are capable of raising themselves as the building they are working on increases in height. These particular cranes are anchored utilizing a long leg. This leg runs down an elevator shaft of the building they are constructing.
