City Cranes
The city crane is a small 2-axle mobile crane that is designed to be used in compact areas where other cranes are not able to go. The city crane could work in between buildings and could travel through gates. In the 1990s, City cranes were developed as a solution to the increasing urban density within Japan. Many cities in the country started building and cramming more structures near each other and it became necessary to have a crane which was capable of navigating through the small areas of Japanese roads.
City cranes are essentially small rough terrain cranes. They are made to be road legal and are characterized by a short chassis, a single cab, a 2-axle design and independent steering on each axle. Additionally, these kinds of machinery provided a retractable slanted boom. This kind of retractable boom takes up a lot less space than a horizontal boom of comparable size would.
Regular Truck Crane
Mobile cranes with a lattice boom are considered conventional truck crane booms. This model has a lighter boom on a hydraulic truck crane. There are many boom parts that 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 is not able to lower and raise utilizing hydraulic power.
Kangaroo Crane
A jumping crane is another name for a kangaroo crane. This model is an articulated-jib slewing crane with an integrated bunker. These cranes started within Australia. They are often used in high-rise construction projects. Kangaroo cranes are unique within the industry in the way that they can raise themselves while the building they are working on increases in height. These specific cranes are anchored utilizing a long leg. This leg runs down an elevator shaft of the building they are constructing.
