This is another type of vertical conveyor. It carries the load moves it. It utilizes gravity-actuated carrier to lowering loads, where the load overcomes the magnitude of a counterweight. It can only be used to lower a load. It can be manually or automatically loaded and/or controlled and can interface with horizontal conveyors. A Vertical Reciprocating Conveyor (VRC) moves materials--in factories, warehouses, industrial plants, institutions--anywhere that products or supplies need to move from one level to another. VRCs are not elevators. In fact, they have their own national code and are specifically exempt from the national elevator code. VRCs provide fast, efficient, convenient and safe access to or from mezzanines, balconies, basements, and between levels in multiple story buildings. They can be installed for through-floor, interior or exterior applications. The principle components of a VRC include guide columns, carriage and a mechanical or hydraulic actuating mechanism.
