City Cranes
A small 2-axle mobile crane, known as a City crane is designed for use within tight spaces where the standard cranes are unable to venture. City cranes are utilized to work within buildings or to travel through gates. During the 1990s, City cranes were developed as a solution to the growing city density in Japan. Lots of cities within Japan started cramming and building more structures near each other and it became necessary to have a crane that was capable of navigating through the small areas of Japanese streets.
Basically, the city crane is a small rough terrain crane. This crane is made to be road legal and is characterized by a single cab, a short chassis, the 2-axle design and independent steering on each axle. Moreover, these kinds of equipments provided a slanted retractable boom. This kind of retractable boom takes up a lot less space than a horizontal boom of similar size would.
Regular Truck Crane
A mobile crane which has a lattice boom is a typical truck crane boom. This unit is lighter than the hydraulic truck crane boom. There are multiple boom sections which could be added to enable the crane to reach up and over an obstacle. A regular truck crane needs separate power to be able to move up and down, because it is not able to raise and lower using hydraulic power.
Kangaroo Crane
