City Cranes
The city crane is a small 2-axle mobile crane which is designed to be utilized in compact areas where other cranes are not able to go. The city crane can work in between buildings and can travel through gates. In the 1990s, City cranes were developed as an answer to the growing urban density in the nation of Japan. Many cities within the country started cramming and building more structures near each other and it became necessary to have a crane which could navigate through the tiny spaces of Japanese roads.
Essentially, the city crane is a small rough terrain crane. This crane is made to be road legal and is characterized by a single cab, a short chassis, the 2-axle design and independent steering on each axle. Moreover, these equipments provided a retractable slanted boom. This style of retractable boom takes up much less space than a horizontal boom of comparable size would.
Standard 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 multiple boom sections which are able to be added to enable the crane to reach up and over an obstacle. A regular truck crane needs separate power in order to move down and up, since it could not lower and raise 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 started within Australia. They are usually utilized in high-rise construction projects. Kangaroo cranes are different 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 utilizing a long leg. This leg runs down the building's elevator shaft.
