City Cranes
The term "City Crane" means a small 2-axle mobile crane which is designed to be utilized particularly in tight areas where regular cranes are unable to venture. These city cranes are great choices to be used in buildings or through gated areas.
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 vital for a crane to have the ability to steer through the nooks and crannies of Japanese streets.
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 single cab, a short chassis and a slanted retractable boom. 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 would be otherwise unaccessible by other crane models.
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 could be added so that the crane could reach up and over an obstacle. Traditional truck cranes require separate power to be able to move up and down and do not lower and raise their loads using any hydraulic power.
The very first ever Speedcrane was made by Manitowoc. It was a successful machine even if further adjustments had to be added. Manitowoc hired Roy Moore as a crane designer to help streamline the design. He understood 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.
