City Cranes
The term "City Crane" means a small 2-axle mobile crane that is made to be utilized specifically in tight areas where standard cranes can not venture. These city cranes are popular choices to be utilized through gated areas or within buildings.
During 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 vital for a crane to have the ability to maneuver through the nooks and crannies of Japanese roads.
Essentially, city cranes are small rough terrain cranes which 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 a lot less space than a comparable horizontal boom would. Combined with the short chassis and the independent steering, the city crane is capable of turning in compact spots which would be otherwise unobtainable by other crane designs.
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 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 require separate power in order to move up and down.
The very first ever Speedcrane was made 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 understood the industry was changing towards internal combustion engines from original steam powered means and designed his crane to change with the times. The Speedcrane was redesigned for a gasoline engine.
