City Cranes
The city crane is a small 2-axle mobile crane that is designed for use in compact 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 increasing urban density within the country of Japan. Lots of cities in the country began cramming and building more structures in close proximity and it became necessary to have a crane that was capable of navigating through the tiny roads in Japan.
Basically, 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. Moreover, these types of machines offered a retractable slanted boom. This kind 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 regular truck crane booms. This unit has a lighter hydraulic truck crane boom. There are multiple boom parts which could be added to allow the crane to reach over and up an obstacle. A typical truck crane needs separate power in order to move down and up, as it is not able to lower and raise using hydraulic power.
Kangaroo Crane
A jumping crane or a kangaroo crane is a articulated-jib slewing crane which is designed with an integrated bunker. These cranes were initially developed within Australia. They are normally utilized 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 specific cranes are anchored using a long leg. This leg runs down an elevator shaft of the building they are constructing.
