With the integration of the world economy, international and regional trading are increasing, which leads to the rapid increase of port throughput and makes loading and unloading efficiency a top priority for ports. The technical characteristics of ship handling machines are therefore developing rapidly towards large, efficient, environmentally friendly, and automated technology. In 1999, in order to build a world-class professional grain port, Beiliang selected Bühler, the leader in ship handling machinery industry, as its strategic cooperative supplier to provide Portalink, a mechanical continuous unloader, and Portaload, a loader. So far, this equpiment has performed efficiently and stably for nearly 20 years.
