City Cranes
The term "City Crane" refers to a small 2-axle mobile crane that is designed to be utilized specially in tight places where regular cranes can not venture. These city cranes are great choices for use in buildings or through gated places.
In the 1990s, city cranes were initially developed in response to the growing urban density within Japan. There are always new construction projects cramming their ways into Japanese cities, making it necessary for a crane to have the ability to navigate the nooks and crannies of Japanese roads.
Basically, city cranes are small rough terrain cranes that are built to be road legal. These cranes are characterized by having a 2-axle design with independent steering on each axle, a single cab, a short chassis and a slanted retractable boom. The slanted retractable boom design takes up much less space than a comparable horizontal boom would. Combined with the independent steering and the short chassis, the city crane could turn in compact spots that will be otherwise unaccessible by other types of cranes.
Conventional Truck Crane
A traditional truck crane is a mobile crane which has a lattice boom. The lattice boom is substantially lighter in weight than a hydraulic truck crane boom. The multiple sections on a lattice boom are able to be added so that the crane can reach over and up an obstacle. Traditional truck cranes require separate power to be able to move down and up and do not raise and lower their loads utilizing any hydraulic power.
Manitowoc made the very first ever Speedcrane. It proved to be a successful machine though many adjustments had to be added later on. Manitowoc hired Roy Moore as a crane designer to help streamline the design. He understood the industry was changing towards internal combustion engines from original steam powered methods and designed his crane to change with the times. The Speedcrane was redesigned for a gasoline engine.
