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 could work in between buildings and could travel through gates. During the 1990s, City cranes were developed as an answer to the growing urban density within Japan. Many cities within the nation began building and cramming more structures near each other and it became necessary to have a crane that was capable of navigating through the tiny spaces of Japanese roads.
Essentially, the city crane is a small rough terrain crane. This crane is designed to be road legal and is characterized by a short chassis, a single cab, independent axle steering, and the 2-axle design. Moreover, these machines offered a slanted retractable boom. This type of retractable boom takes up much less space compared to a horizontal boom of similar size would.
Conventional Truck Crane
A mobile crane that has a lattice boom is a regular truck crane boom. This model is lighter compared to the hydraulic truck crane boom. There are multiple boom parts that are able to be added to enable the crane to reach up and over an obstacle. A standard truck crane needs separate power to be able to move down and up, as it could not lower and raise with hydraulic power.
Kangaroo Crane
A jumping crane is a different name for a kangaroo crane. This model 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 different in the business in the way that they are capable of raising themselves while the building they are working on increases in height. These particular cranes are anchored using a long leg. This leg runs down an elevator shaft of the building they are constructing.
