Depending on the type of their power mechanism, Vertical Reciprocating Conveyor Lift Conveyors Systems (VRCs) are mainly classified into two types: hydraulic and mechanical. Hydraulic VRCs utilise hydraulic cylinders to power the conveyor, while mechanical VRCs electrically power a lift for heavier loads. While mechanical VRCs are more dynamic in configuration and have a longer lifespan, their higher cost is a major disadvantage.
