City Cranes
The city crane is a small 2-axle mobile crane which is designed to be used in tight spaces where other cranes are not able to go. The city crane can work in between buildings and can travel through gates. During the 1990s, City cranes were developed as a solution to the growing urban density in Japan. Many cities within the nation began building and cramming more structures in close proximity and it became necessary to have a crane that can navigate through the small spaces 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. Furthermore, these machines provided a retractable slanted boom. This kind of retractable boom takes up a lot less space compared to a horizontal boom of the same size would.
Conventional Truck Crane
Mobile cranes with a lattice boom are considered regular truck crane booms. This unit has a lighter boom on a hydraulic truck crane. There are many boom sections which are able to be added to allow the crane to reach up and over an obstacle. A standard truck crane needs separate power to be able to move down and up, because it is not able to raise and lower using hydraulic power.
Kangaroo Crane
A jumping crane is another name for a kangaroo crane. This unit is an articulated-jib slewing crane with an integrated bunker. These cranes originated within Australia. They are often used in high-rise construction projects. Kangaroo cranes are unique in the industry in the way that they can raise themselves as 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.
