City Cranes
A small 2-axle mobile crane, referred to as a City crane is designed for use within compact areas where the regular cranes could not venture. City cranes are utilized to work inside buildings or to travel through gates. In the 1990s, City cranes were developed as a solution to the growing city density in Japan. Many cities within the nation started building and cramming more structures in close proximity and it became necessary to have a crane which was capable of navigating through the small areas of Japanese streets.
City cranes are basically 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. Additionally, these types of machinery offered a retractable slanted boom. This kind of retractable boom takes up much less space than a horizontal boom of similar size would.
Standard Truck Crane
A mobile crane which has a lattice boom is a regular truck crane boom. This model is lighter than the boom on a hydraulic truck crane. There are many boom sections that could be added to enable the crane to reach up and over an obstacle. A conventional truck crane requires separate power in order to move up and down, as it could not lower and raise using 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 normally used in high-rise construction projects. Kangaroo cranes are unique within the industry in the way that they could raise 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.
