City Cranes
The term "City Crane" refers to a small 2-axle mobile crane that is designed to be utilized particularly in compact areas where standard cranes could not venture. These city cranes are great choices to be utilized within buildings or through gated places.
In the 1990s, city cranes were originally 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 steer through the nooks and crannies of Japanese roads.
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 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 can turn in compact spots that will be otherwise unobtainable by other crane designs.
Conventional Truck Crane
A traditional truck crane is a mobile crane that has a lattice boom. The lattice boom is substantially lighter in weight than a hydraulic truck crane boom. The many sections on a lattice boom can be added so that the crane can reach over and up an obstacle. Traditional truck cranes need separate power to be able to move up and down and do not raise and lower their loads with any hydraulic power.
Manitowoc built the very first ever Speedcrane. It proved to be a successful device though lots of 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 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.
