City Cranes
The city crane is a small 2-axle mobile crane which is designed to be used in tight spaces where other cranes could not go. The city crane could work in between buildings and can travel through gates. During the 1990s, City cranes were developed as a solution to the growing urban density within Japan. A lot of cities within Japan began cramming and building more structures in close proximity and it became necessary to have a crane that can navigate through the small spaces of Japanese roads.
City cranes are basically small rough terrain cranes. They are designed to be road legal and are characterized by a short chassis, a single cab, a 2-axle design and independent steering on each axle. Furthermore, these machinery offered a retractable slanted boom. This type of retractable boom takes up much less space than a horizontal boom of similar size would.
Standard Truck Crane
A mobile crane which has a lattice boom is a standard truck crane boom. This unit is lighter compared to the hydraulic truck crane boom. There are many boom parts which are able to be added to allow the crane to reach up and over an obstacle. A typical truck crane requires separate power to be able to move down and up, as it is not able to raise and lower with hydraulic power.
Kangaroo Crane
A jumping crane is another name for a kangaroo crane. This model is an articulated-jib slewing crane with an integrated bunker. These cranes originated in Australia. They are usually used in high-rise construction projects. Kangaroo cranes are unique within the business in the way that they are capable of raising themselves while the building they are working on increases in height. These particular cranes are anchored by a long leg. This leg runs down an elevator shaft of the building they are constructing.
