Before starting on assembly - you should master part modeling techniques.
Have you modeled any of your crane and bucket parts?
For practice on assemblies - there are many assemblies (with, of course, parts) in the Samples folder.
I recommend that you open one of these assemblies.
Start a new assembly file.
Tile the two assembly windows side-by-side.
Build new assembly using the finished Sample assembly as a guide.
Repeat for all of the Samples.
