City Cranes
"City Crane" is a term utilized to define small 2-axle mobile cranes that could operate in tight spaces where the standard crane cannot access. These city cranes are popular alternatives to be utilized through gated places or within buildings.
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 navigate 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 slanted retractable boom, a single cab and a short chassis. The slanted retractable boom design takes up less space than a comparable horizontal boom would. Combined with the short chassis and the independent steering, the city crane can turn in compact spots which will be otherwise unobtainable 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 significantly lighter in weight than a hydraulic truck crane boom. The many sections on a lattice boom can be added so that the crane could reach up and over an obstacle. Traditional truck cranes need separate power to be able to move up and down and do not lower and raise their loads utilizing any hydraulic power.
The first ever Speedcrane was made by Manitowoc. It was a successful device even though further adjustments needed to be added. Manitowoc hired Roy Moore as a crane designer to help streamline the design. He knew the industry was moving 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.
