City Cranes
The city crane is a small 2-axle mobile crane which is designed for use in tight areas 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 a solution to the increasing urban density in the nation of Japan. Numerous cities in Japan began cramming and building more structures in close proximity and it became necessary to have a crane which was capable of navigating through the tiny roads in Japan.
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, independent axle steering, and the 2-axle design. Furthermore, these kinds of machines offered a retractable slanted boom. This type of retractable boom takes up a lot less space than a horizontal boom of comparable size would.
Standard 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 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 up and down, since it is not able to raise and lower using hydraulic power.
Kangaroo Crane
A jumping crane or a kangaroo crane is a articulated-jib slewing crane that is designed with an integrated bunker. These cranes were initially developed within Australia. They are often used in high-rise construction projects. Kangaroo cranes are different in the industry in the way that they are capable of raising themselves as the building they are working on increases in height. These particular cranes are anchored by a long leg. This leg runs down an elevator shaft of the building they are constructing.
