City Cranes
"City Crane" is a term utilized to define small 2-axle mobile cranes which can operate in compact spaces where the typical crane cannot access. These city cranes are great choices to be utilized inside buildings or through gated areas.
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 vital for a crane to have the ability to maneuver through the nooks and crannies of Japanese streets.
Essentially, city cranes are small rough terrain cranes that are made to be road legal. These cranes are characterized by having a 2-axle design with independent steering on each axle, a short chassis, a slanted retractable boom and a single cab. 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 could turn in compact spots which will be otherwise unaccessible by other crane models.
Conventional Truck Crane
A traditional truck crane is a mobile crane that has a lattice boom. The lattice boom is significantly lighter in weight compared to a hydraulic truck crane boom. The many sections on a lattice boom could be added so that the crane could reach up and over an obstacle. Conventional truck cranes need separate power to be able to move up and down and do not raise and lower their cargo with any hydraulic power.
The very first ever Speedcrane was made by Manitowoc. It was a successful device even though further adjustments had to be added. 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.
