City Cranes
The term "City Crane" refers to a small 2-axle mobile crane that is made to be utilized particularly in compact places where regular cranes are unable to venture. These city cranes are great alternatives to be used inside buildings or through gated areas.
City cranes were initially developed during the 1990s as a response to the increasing urban density in Japan. There are continually new construction projects cramming their ways into the cities in Japan, 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 built 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 could turn in tight spots which will be otherwise unaccessible by other types of cranes.
Conventional Truck Crane
Conventional truck cranes are mobile cranes with lattice booms. This boom is a lot lighter boom than is found with a hydraulic truck crane boom. The many sections on a lattice boom are able to be added so that the crane could reach over and up an obstacle. Traditional truck cranes require separate power in order to move down and up and do not raise and lower their cargo with any hydraulic power.
The very first ever Speedcrane was built by Manitowoc. It was a successful equipment even if further adjustments needed to be added. Manitowoc hired Roy Moore as a crane designer to help streamline the design. He knew 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.
