A mezzanine lift, or vertical reciprocating conveyor (VRC), moves material between floor level and a mezzanine or upper level. It is the standard way to get pallets, carts, and loads up to a platform, and it is purpose-built for freight, not people.
Where a forklift reaching up to a mezzanine or a crew muscling loads up stairs creates fall and tip hazards, a VRC carries the load on a guarded carriage inside an enclosed hoistway. That removes those hazards and moves more weight per cycle. Mechanical and hydraulic models size to load weight, platform height, and carriage dimensions.
