  • dragline excavator

    a dragline excavator is a piece of heavy equipment used in civil engineering and surface mining. draglines fall into two broad categories: those that are based on standard, lifting cranes, and the heavy units which have to be built on-site. most cler cranes, with an added winch drum on the front, can act as a dragline. these units are designed to be dismantled and transported over the road on flatbed trailers. draglines used in civil engineering are almost always of this smaller, crane type.

  • machine

    a machine is a mechanical structure that uses power to apply forces and control movement to perform an intended action. machines can be driven by animals and people, by natural forces such as wind and water, and by chemical, thermal, or electrical power, and include a system of mechanisms that shape the actuator input to achieve a specific application of output forces and movement. they can also include computers and sensors that monitor performance and plan movement, often called mechanical sys
