City Cranes
"City Crane" is a term utilized to define small 2-axle mobile cranes that can operate in tight spaces where the standard crane could not access. These city cranes are great alternatives to be utilized within buildings or through gated areas.
In the 1990s, city cranes were initially developed in response to the growing urban density within Japan. There are continually 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 that are built 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 a lot less space than a comparable horizontal boom would. Combined with the independent steering and the short chassis, the city crane is capable of turning in compact spots which will be otherwise unobtainable by other kinds of cranes.
Conventional Truck Crane
A conventional 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 multiple sections on a lattice boom are able to be added so that the crane could reach up and over an obstacle. Conventional truck cranes do not raise and lower their cargo utilizing any hydraulic power and need separate power to be able to move up and down.
The first ever Speedcrane was made by Manitowoc. It was a successful machine even if further adjustments needed to be added. Manitowoc hired Roy Moore as a crane designer to help streamline the design. He understood the industry was moving towards IC engines from original steam powered means and designed his crane to change with the times. The Speedcrane was redesigned for a gasoline engine.
