Modular Construction of BECO 380W Excavator 810989

The 380W dragline is Bucyrus-Erie's first modular designed dragline. The modular concept applies simplified field connections for assembly of components rather than field welding, resulting in shorter erection times and lower erection costs. The various modules are described. The advantages during field erection are discussed. Comparison of erection time with a larger dragline is made. Discussions of design aids, namely use of finite element analysis is included.
