City Cranes
"City Crane" is a term used to define small 2-axle mobile cranes which can operate in tight spaces where the standard crane cannot access. These city cranes are great choices to be utilized through gated places or in buildings.
In 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.
Basically, 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 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 is capable of turning in tight spots that will be otherwise unaccessible by other crane models.
Conventional Truck Crane
A traditional truck crane is a mobile crane which 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 can reach up and over an obstacle. Traditional truck cranes need separate power to be able to move down and up and do not lower and raise their loads using any hydraulic power.
The first ever Speedcrane was built by Manitowoc. It was a successful machine even though 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 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.
