City Cranes
The city crane is a small 2-axle mobile crane which is designed to be used in tight spaces where other cranes could not go. The city crane can work in between buildings and can travel through gates. During the 1990s, City cranes were developed as a solution to the growing urban density in the country of Japan. Numerous cities in the country started building and cramming more structures near each other and it became necessary to have a crane that was capable of navigating through the tiny streets 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. Moreover, these kinds of machines provided a slanted retractable boom. This style of retractable boom takes up much less space than a horizontal boom of similar size would.
Standard Truck Crane
A mobile crane which has a lattice boom is a typical truck crane boom. This unit is lighter than the boom on a hydraulic truck crane. There are multiple boom sections that are able to be added to allow the crane to reach over and up an obstacle. A conventional truck crane needs separate power to be able to move up and down, since it could not raise and lower utilizing 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 started within Australia. They are often used in high-rise construction projects. Kangaroo cranes are unique within the business 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.
