City Cranes
The city crane is a small 2-axle mobile crane which is designed to be used in tight spaces where other cranes are not able to go. The city crane could work in between buildings and can travel through gates. In the 1990s, City cranes were developed as an answer to the growing city density within Japan. Many cities within Japan started building and cramming more structures in close proximity and it became necessary to have a crane that was capable of navigating through the tiny areas 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 single cab, a short chassis, the 2-axle design and independent steering on each axle. Furthermore, these types of equipments provided a slanted retractable boom. This style of retractable boom takes up a lot less space than a horizontal boom of similar size would.
Standard Truck Crane
A mobile crane which has a lattice boom is a conventional truck crane boom. This unit is lighter compared to the hydraulic truck crane boom. There are many boom parts 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, as it is not able to raise and lower utilizing 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 started within 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 by a long leg. This leg runs down an elevator shaft of the building they are constructing.
