Overview
The F Series handles the heaviest loads. The D Series handles the simplest installations. The M Series handles everything in between — and more. PFlow calls it “The Most Versatile VRC in the Industry” because the M Series covers the widest range of applications in a single platform: straddle or cantilever configurations, capacities to 10,000 lbs, unlimited vertical rise, unlimited cycles, and the ability to serve any number of floor levels at speeds up to 400 fpm.
Where a four-post F Series lift may be more structure than the application requires, and a two-level hydraulic D Series doesn’t have the capacity, speed, or rise — the M Series fills the gap with a two-post mechanical design that adapts to nearly any multi-level material transfer challenge.

Straddle or Cantilever — One Platform, Two Configurations
The M Series is available in both straddle (columns on both sides) and cantilever (columns on one side) configurations. This gives facility planners the flexibility to choose the layout that best fits the available space, loading direction, and overhead clearance — without switching to a different product line or manufacturer. Straddle for maximum stability and larger platforms. Cantilever for smaller footprints, lower headroom, and side-loading capability.
Optional Quantum Drive
The M Series offers an optional Quantum Drive — PFlow’s advanced drive technology that delivers enhanced safety and stability beyond standard chain-drive systems. The Quantum Drive provides smoother acceleration and deceleration, more precise carriage positioning, and an additional layer of mechanical safety for critical applications where load stability is paramount.
Safety Features
- Limit switches shut down the motor and engage the brake when tripped or on power loss
- Chain sensors shut down the lift if chain tension is lost
- Certified safety cams prevent carriage descent in the event of chain failure
- Chain tensioners and guides prevent chains from jumping sprockets
- Optional DeckLock safety system for added security at upper levels
- Interlocked gates with 8-foot enclosures per ASME B20.1
Construction and Options
The carriage is lifted and lowered by heavy-duty roller chains attached to a synchronized mechanical lifting mechanism on top of 6-inch guide columns. Optional hot-dipped galvanized or epoxy finishes are available for outdoor and wash-down environments. Explosion-proof components can be specified for classified areas.
Applications
The M Series serves manufacturing facilities, distribution centers, multi-story warehouses, food and beverage processing, pharmaceutical production, automotive assembly, and any application that needs a versatile two-post mechanical VRC capable of reaching multiple levels at high speed with unlimited cycles. Its combination of capacity, rise, speed, and configuration flexibility makes it the right choice when the application doesn’t fit neatly into a hydraulic, delta, or four-post category.
