City Cranes
The city crane is a small 2-axle mobile crane that is designed to be used in tight areas where other cranes could not go. The city crane could work in between buildings and could travel through gates. In the 1990s, City cranes were developed as an answer to the growing city density within the country of Japan. Numerous cities in the country began cramming and building 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 single cab, a short chassis, the 2-axle design and independent steering on each axle. Furthermore, these types of equipments offered a slanted retractable boom. This style of retractable boom takes up much 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 boom on a hydraulic truck crane. There are multiple boom parts that could be added to enable the crane to reach up and over an obstacle. A regular truck crane needs separate power to be able to move down and up, because it is not able to raise and lower with hydraulic power.
Kangaroo Crane
A kangaroo crane or jumping crane is a articulated-jib slewing crane that is made with an integrated bunker. These cranes were initially developed within Australia. They are normally utilized in high-rise construction projects. Kangaroo cranes are unique within the business in the way that they can raise themselves while the building they are working on increases in height. These specific cranes are anchored by a long leg. This leg runs down the building's elevator shaft.
