City Cranes
A small 2-axle mobile crane, known as a City crane is designed to be utilized in compact areas where the regular cranes are unable to venture. City cranes are utilized to work in buildings or to travel through gates. During the 1990s, City cranes were developed as an answer to the increasing urban density in the country of Japan. Numerous cities within Japan began cramming and building more structures in close proximity and it became necessary to have a crane which was capable of navigating through the small roads in Japan.
Essentially, the city crane is a small rough terrain crane. This crane is designed to be road legal and is characterized by a single cab, a short chassis, independent axle steering, and the 2-axle design. Moreover, these types of machinery offered a retractable slanted boom. This style of retractable boom takes up a lot less space compared to a horizontal boom of comparable size would.
Conventional Truck Crane
A mobile crane that has a lattice boom is a typical truck crane boom. This unit is lighter compared to the hydraulic truck crane boom. There are many boom sections that could be added to allow the crane to reach up and over an obstacle. A typical truck crane needs separate power in order to move up and down, because it could not raise and lower with hydraulic power.
Kangaroo Crane
A jumping crane or a kangaroo crane is a articulated-jib slewing crane that is made with an integrated bunker. These cranes were initially developed in Australia. They are often used in high-rise construction projects. Kangaroo cranes are unique in the industry in the way that they are capable of raising 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.
