Vertical Reciprocating Conveyor (VRC) Subcommittee

Publications & Technical Resources

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 the Material Handling Industry of America 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 MHIA 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.

Seismic Design Maps Using USGS Spectral Response Data
For any seismic design considerations concerning VRC installations, the US Geological Survey provides links to maps, data, and tools for engineers interested in seismic design of buildings. There are two separate tools for buildings, for present and future model building codes respectively: a Java Ground Motion Parameter Calculator and a U.S. Seismic “DesignMaps” Web Application.
