City Cranes
The city crane is a small 2-axle mobile crane that is designed to be utilized in tight 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 growing city density within the nation of Japan. Numerous cities in Japan started 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 made 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 equipments offered a slanted retractable boom. This type of retractable boom takes up much less space compared to a horizontal boom of the same size would.
Conventional Truck Crane
A mobile crane that has a lattice boom is a conventional truck crane boom. This model is lighter than the hydraulic truck crane boom. There are multiple boom sections which are able to be added to allow the crane to reach over and up an obstacle. A standard truck crane needs separate power to be able to move up and down, because it is not able to raise and lower 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 normally used in high-rise construction projects. Kangaroo cranes are unique in the industry 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 using a long leg. This leg runs down an elevator shaft of the building they are constructing.
