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 can work in between buildings and can travel through gates. During the 1990s, City cranes were developed as an answer to the growing city density in Japan. A lot of cities in Japan started building and cramming more structures near each other and it became necessary to have a crane that could navigate through the tiny 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, the 2-axle design and independent steering on each axle. Furthermore, these machines offered a slanted retractable boom. This style of retractable boom takes up much less space compared to a horizontal boom of comparable size would.
Regular Truck Crane
Mobile cranes with a lattice boom are considered standard truck crane booms. This model has a lighter boom on a hydraulic truck crane. There are multiple boom sections that could be added to allow the crane to reach over and up an obstacle. A typical truck crane requires separate power to be able to move up and down, as it could not lower and raise utilizing hydraulic power.
Kangaroo Crane
A jumping crane is a different name for a kangaroo crane. This unit is an articulated-jib slewing crane with an integrated bunker. These cranes started in Australia. They are usually 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 particular cranes are anchored using a long leg. This leg runs down the building's elevator shaft.
