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 could travel through gates. In the 1990s, City cranes were developed as a solution to the growing city density within the nation of Japan. Lots of cities in Japan began building and cramming more structures in close proximity and it became necessary to have a crane that can navigate through the small areas of Japanese roads.
Basically, the city crane is a small rough terrain crane. This crane is made to be road legal and is characterized by a short chassis, a single cab, independent axle steering, and the 2-axle design. Additionally, these kinds of machinery offered a retractable slanted boom. This type of retractable boom takes up a lot less space than a horizontal boom of comparable size would.
Regular Truck Crane
Mobile cranes with a lattice boom are considered typical truck crane booms. This unit has a lighter 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 with hydraulic power.
Kangaroo Crane
A jumping crane is another name for a kangaroo crane. This model is an articulated-jib slewing crane with an integrated bunker. These cranes originated in Australia. They are usually used in high-rise construction projects. Kangaroo cranes are unique 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 utilizing a long leg. This leg runs down an elevator shaft of the building they are constructing.
