Description

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. A mobile crane is any mobile crane, i.e. one that is easily moved from one location to another, sometimes while carrying a load. However, in general parlance, a "mobile crane" tends to be a rubber-wheeled crane vehicle. Mobile cranes generally operate via a truss / boom from which end a hook is suspended by wire rope and sheaves. The wire ropes are operated by whatever prime movers the designers have available, operating through a variety of transmissions. Steam engines, electric motors and internal combustion engines (IC) have all been used. Older cranes' transmissions tended to be clutches. This was later modified when using IC engines to match the steam engines "max torque at zero speed" characteristic by the addition of a hydrokinetic element culminating in controlled torque converters. The operational advantages of this arrangement can now be achieved by electronic control of hydrostatic drives, which for size and other considerations is becoming standard.show more
