City Cranes
The term "City Crane" means a small 2-axle mobile crane that is made to be utilized specifically in compact places where regular cranes could not venture. These city cranes are popular choices to be utilized inside buildings or through gated places.
During the 1990s, city cranes were originally 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 steer through the nooks and crannies of Japanese streets.
Basically, city cranes are small rough terrain cranes which are made 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 a lot less space than a comparable horizontal boom would. Combined with the short chassis and the independent steering, the city crane is capable of turning in compact spots which would be otherwise unaccessible by other kinds of cranes.
Conventional Truck Crane
A traditional truck crane is a mobile crane that has a lattice boom. The lattice boom is substantially lighter in weight compared to a hydraulic truck crane boom. The many 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 up and down and do not lower and raise their cargo using any hydraulic power.
The very first ever Speedcrane was built by Manitowoc. It was a successful machine even though further adjustments needed to be added. Manitowoc hired Roy Moore as a crane designer to help streamline the design. He understood the industry was changing towards IC engines from original steam powered methods and designed his crane to change with the times. The Speedcrane was redesigned for a gasoline engine.
