City Cranes
The term "City Crane" means a small 2-axle mobile crane which is made to be utilized specially in compact places where regular cranes are unable to venture. These city cranes are great choices to be utilized inside buildings or through gated areas.
During the 1990s, city cranes were initially developed in response to the growing urban density in Japan. There are continually new construction projects cramming their ways into the cities in Japan, making it necessary for a crane to have the ability to maneuver through the nooks and crannies of Japanese roads.
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 independent steering and the short chassis, the city crane could turn in compact spots which will be otherwise unaccessible by other kinds of cranes.
Conventional Truck Crane
Traditional truck cranes are mobile cranes with lattice booms. This boom is much lighter boom than is found with a hydraulic truck crane boom. The multiple sections on a lattice boom could be added so that the crane can reach over and up an obstacle. Conventional truck cranes need separate power in order to move up and down and do not lower and raise their loads utilizing any hydraulic power.
Manitowoc made the very first ever Speedcrane. It proved to be a successful machine although many adjustments needed to be added later on. Manitowoc hired Roy Moore as a crane designer to help streamline the design. He knew 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.
