City Cranes
A small 2-axle mobile crane, known as a City crane is designed to be utilized in tight areas where the usual cranes could not venture. City cranes are used to work in buildings or to travel through gates. During the 1990s, City cranes were developed as an answer to the growing city density in the country of Japan. Numerous cities in the country started cramming and building more structures in close proximity and it became necessary to have a crane that can navigate through the tiny streets in Japan.
City cranes are essentially small rough terrain cranes. They are designed to be road legal and are characterized by a single cab, a short chassis, a 2-axle design and independent steering on each axle. In addition, these kinds of machines offered a retractable slanted boom. This type of retractable boom takes up a lot less space compared to a horizontal boom of the same size would.
Standard Truck Crane
Mobile cranes with a lattice boom are considered standard truck crane booms. This unit has a lighter boom on a hydraulic truck crane. There are multiple boom parts which are able to be added to enable the crane to reach up and over an obstacle. A standard truck crane needs separate power in order to move down and up, because it could not lower and raise using hydraulic power.
Kangaroo Crane
A jumping crane or a kangaroo crane is a articulated-jib slewing crane which is made with an integrated bunker. These cranes were initially developed within Australia. They are often utilized in high-rise construction projects. Kangaroo cranes are different in the industry in the way that they could raise themselves while the building they are working on increases in height. These specific cranes are anchored using a long leg. This leg runs down an elevator shaft of the building they are constructing.
