City Cranes
The city crane is a small 2-axle mobile crane which is designed for use in compact areas where other cranes are not able to go. The city crane can work in between buildings and can travel through gates. During the 1990s, City cranes were developed as an answer to the increasing urban density in the nation of Japan. Numerous cities in the country began cramming and building more structures near each other and it became necessary to have a crane which could navigate 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 short chassis, a single cab, independent axle steering, and the 2-axle design. Additionally, these kinds of machinery offered a slanted retractable boom. This style of retractable boom takes up a lot less space than a horizontal boom of similar 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 allow the crane to reach over and up an obstacle. A typical truck crane needs separate power to be able to move up and down, as it could not raise and lower with hydraulic power.
Kangaroo Crane
A jumping crane or a kangaroo crane is a articulated-jib slewing crane that is made with an integrated bunker. These cranes were first 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 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.
