City Cranes
The city crane is a small 2-axle mobile crane that is designed to be used in tight 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 urban density in Japan. Numerous cities within Japan began building and cramming more structures near each other and it became necessary to have a crane that was capable of navigating through the small spaces of Japanese roads.
Essentially, the city crane is a small rough terrain crane. This crane is designed to be road legal and is characterized by a short chassis, a single cab, independent axle steering, and the 2-axle design. In addition, these kinds of equipments provided a retractable slanted boom. This kind of retractable boom takes up a lot less space than a horizontal boom of comparable 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 that could be added to allow the crane to reach up and over an obstacle. A standard truck crane needs separate power in order to move up and down, since it is not able to lower and raise utilizing hydraulic power.
Kangaroo Crane
A kangaroo crane or jumping crane is a articulated-jib slewing crane which is designed with an integrated bunker. These cranes were initially developed in Australia. They are usually used in high-rise construction projects. Kangaroo cranes are different within 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.
