City Cranes
The city crane is a small 2-axle mobile crane that is designed to be used in tight areas where other cranes are not able to go. The city crane could work in between buildings and can travel through gates. During the 1990s, City cranes were developed as a solution to the growing urban density within the nation of Japan. Many cities within the country started cramming and building more structures in close proximity and it became necessary to have a crane which can navigate through the small spaces of Japanese streets.
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. Furthermore, these machines provided 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 that has a lattice boom is a regular truck crane boom. This unit is lighter compared to the hydraulic truck crane boom. There are multiple boom sections that could be added to enable the crane to reach over and up an obstacle. A regular truck crane needs separate power in order to move down and up, as it could not raise and lower utilizing hydraulic power.
Kangaroo Crane
A jumping crane or a kangaroo crane is a articulated-jib slewing crane which is made with an integrated bunker. These cranes were initially developed within Australia. They are often used in high-rise construction projects. Kangaroo cranes are unique 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 utilizing a long leg. This leg runs down the building's elevator shaft.
