Serco's Vertical Storing Leveler (VSL) works in conjunction with a dock configuration that allows facilities to open truck trailer doors into the building. The VSL bridges the gap between a truck trailer and dock doorway. According to Serco, this configuration allows facilities to save money through lower energy bills, loss prevention and increased productivity.
