When a concrete mixing plant is listed as mobile or portable, that simply means it was designed to be moved. Our rule of thumb is a mobile concrete mixing plant is able to be easily transported to a site and setup without the use of additional equipment such as a telehandler or crane. We consider a portable concrete mixing plant a plant that was designed to be moved (usually has factory installed axles and king pins, often install in modules) but requires additional equipment for install such as a crane or telehandler. In reality their is no specific guideline to outline the difference between a mobile concrete plant or portable concrete plant.
