derreck crane

  • A derrick crane is a specific style of lifting machine. It is usually a fixed crane, meaning it is assembled and disassembled in the location where it is used, although there are some very small mobile styles. Generally, the crane is characterized by its long, fixed length tower.

  • The most basic type of derrick is controlled by three or four lines connected to the top of the mast, which allow it both to move laterally and cant up and down. To lift a load, a separate line runs up and over the mast with a hook on its free end, as with a crane. Forms of derricks are commonly found aboard ships and at docking facilities.

  • What is the difference between a crane and a derrick?

    Cranes and derricks are hoisting machines used to lift and move heavy loads in such places as factories, shipyards and at construction sites. Most derricks are stationary while most cranes can move from place to place under their own power. Engineers, however, sometimes use either name to describe the same machine.
