MHI Industry Series: The Role of Vertical Reciprocating Conveyors (VRCs) in Modern Warehousing
The latest MHI Industry Series on The New Warehouse Podcast features Steve Castle from AutoQuip and Chuck Cobb from PFlow. They discuss the evolution of Vertical Reciprocating Conveyors (VRCs) and their role in modern warehousing. The episode also covers the technological advancements shaping the future of VRCs. VRCs are essential in material handling, offering a safer and more efficient way to transport materials vertically. As part of MHI’s Conveyor and Sortation Systems (CSS) group, VRCs continue to adapt to industry needs.
The Evolution of Vertical Reciprocating Conveyors
VRCs, also known as freight lifts or material lifts, originated in the early 1970s. Initially, they were required to operate at an incline due to industry regulations, but a landmark legal victory allowed for vertical movement. “The judge ruled in favor of true vertical movement, recognizing that an incline was unnecessary,” Cobb recalls, highlighting the pivotal court decision that shaped the industry.
Unlike traditional conveyors that move materials horizontally, VRCs operate vertically, making them essential for multi-level warehouses. Despite their importance, the industry remains relatively small, with only a handful of manufacturers specializing in VRC production.
Vertical Reciprocating Conveyors: Key Benefits and Applications
VRCs primarily transport materials between warehouse levels, reducing the need for manual lifting and improving efficiency. “The primary difference between VRCs and other conveyors is that we typically have a singular platform that moves between levels,” Castle explains.
Applications for VRCs vary widely:
- Multi-level warehouses: VRCs enable seamless movement of pallets, carts, and other goods across multiple floors.
- Automated systems: VRCs can integrate with Automated Guided Vehicles (AGVs) and Autonomous Mobile Robots (AMRs) to streamline warehouse operations.
- Safety compliance: Unlike standard conveyors, a VRC requires specific guarding and interlocked gates to prevent falls and injuries. “Every state has different codes for VRCs, and some don’t even require full guarding unless it’s manually loaded,” Cobb notes.
The Future of VRCs: Automation and Safety Enhancements
As warehouses become more automated, VRCs are evolving to meet new demands. “We’re seeing more requests for VRCs with built-in robots that pick and place items directly onto the lift,” Cobb says. This shift eliminates manual handling and enhances precision in material movement.
Safety remains a top priority. “The B20.1 code is changing from saying risk assessments ‘should’ be done to ‘shall’ be done,” Castle points out, emphasizing the growing focus on regulatory compliance. These assessments drive new safety features such as:
- Photo-eye sensors to measure load heights and prevent overloading.
- Light curtains and barriers to detect unauthorized access and stop lift operations.
- Redundant safety circuits ensure proper load placement before activation.
The Vertical Reciprocating Conveyor (VRC) Subcommittee operates under the CSS group within MHI. As a specialized division, this subcommittee focuses on establishing safety standards, promoting best practices, and driving innovation in vertical material transportation.
Key Takeaways on Vertical Reciprocating Conveyors
- VRCs provide efficient vertical transportation for warehouses, optimizing space and streamlining operations.
- They integrate with automation technologies such as AGVs and AMRs, reducing manual handling and increasing throughput.
- Regulatory changes drive enhanced safety features, making VRCs safer and more compliant with industry standards.
- Advanced control systems allow precise communication between VRCs and warehouse management systems (WMS) to prevent operational errors.
