Through net research ive found quite a few portable cranes that are manufactured and mass produced by companies such as : Abus Cranes , Spanco Inc, Contrx Cranes etc.
The most ideal crane most of these companies supply is the Jib crane:
From our first few meetings we've identified flaws to this design in out particular situation (such as the platform and the mobility) and we're planning to go for quite a different design.Finance
Ive done some research on manufacturing finance (via previous lecture notes). Some equations essential to finding the manufacturing cost of the crane parts is shown below :
Manufacturing Cost(Mi) = Material Cost(Mc) +( Processing Cost(Pc) * Cost Coefficient(Rc))
[Mi=Mc+(Pc.Rc)]
Material Cost(Mc) = Total volume of material to produced part(v) * Cost of material per unit volume (cmt)
[Mc=V.Cmt]
The material we discussed so far in using is an Aluminium alloy, but that ofcourse is subject to change.
Manufacturing costs will alter depending on the method of manufacturing and the individual shape complexity, but that will be something we will discuss in the near future.
