Here is a very detailed model of a push cart. It was built to scale using real-word measurements and CAD drawings as a reference. It was created in 3DS MAX 2013 and uses standard Mentalray materials which can easily be changed.
No bit maps are used on the models for hassle-free network rendering. The parts are intelligently named and grouped. When possible, object pivot points are placed where they should be for logical animation and parametric objects are left un-collapsed so that you can adjust and animate them, when desired. This model is ready to be dropped into your scenes and rendered.
