VRC Application Guidelines
The Application Guidelines for Vertical Reciprocating Conveyors were thoroughly revised from the original 1991 Version which they replace. They were prepared as a result of the VRC Sub-Committee's recognition of a need to develop comprehensive safety guidelines and establish a minimum design criteria for when such are used in conjunction with ASME B20.1 - The Safety Standard for Conveyors and Related Equipment.
VRC Installer Guidelines
Proper installation of Vertical Reciprocating Conveyors (VRCs) is vital to the the safety of the operators, the efficiency of the unit, and the ultimate satisfaction of the end user. These guidelines have been prepared by member companies of the Material Handling Industry’s VRC Subcommittee to assist the VRC installers in understanding their role and responsibility in providing customers with a safe and reliable VRC.
Industry Position on the Regulation of VRCs
This position paper has been prepared by the VRC Subcommittee of the Conveyor Product Section of MHI and is intended to express the industry’s formal position regarding the proper application of recognized Safety Codes to VRCs. More specifically, it is the intent of this MHI Subcommittee to place into the hands of VRC equipment suppliers, installers, end users, inspectors and any other Authority Having Jurisdiction (AHJ) a clear and definitive argument as to the validity of applying only ASME B20.1 to Vertical Reciprocating Conveyors.
Myth-Busting Material Lifts Presentation
A "Material Lift" or just "Lifting Material"?

Two Post Cantilever Lift

Two Post Cantilever Lift Two Post Cantilever Lift

The carriage is guided and supported by two masts, both of which are located on the same side of the carriage. Two post cantilever lifts are most commonly actuated by either electro-hydraulic or electro-mechanical means. Because three sides of the carriage can be accessed, this style lift can accommodate "C", "Z" and 90 degree loading patterns.

The carriage is guided by and suspended between two masts that are located on opposite sides of the carriage. Two post straddle lifts are most commonly actuated by either electro-hydraulic or electro-mechanical means. Because two sides of the carriage cannot be accessed due to the location of the two masts, this style lift is restricted to "C" and "Z" loading patterns.

Four Post Lift

Two Post Straddle Lift Two Post Straddle Lift

This special type of straddle lift carriage is guided by and suspended between two sets of two masts that are located on opposite sides of the carriage. Four post lifts are used in applications where large carriages and/or higher capacities are required, and are most commonly actuated by either electro-mechanical or electro-hydraulic means. Although the two side of the carriage adjacent to the masts have limited access, this style lift can accommodate "C", "Z" and 90 degree loading patterns.
