21 Series–Hydraulic Vertical Lift
21 Series–Hydraulic Vertical Lift
A LEVEL CARRIAGE REGARDLESS OF LOAD PLACEMENT
The 21 Series vertical reciprocating conveyor (VRC) from PFlow Industries is a 2-post hydraulic lift that can handle loads of up to 6,000 pounds. The overall lifting capacity is determined by the carriage size and added options that increase its overall weight.
With a maximum carriage size of up to 12’ wide by 10’ long, the 21 Series VRC easily conveys a wide variety of materials, including materials on pallets. Available in cantilever or straddle configurations, the 21 Series VRC is lifted and lowered by chain over sprocket actuated by guide column-mounted hydraulic cylinders. A torsion bar links the two hydraulic cylinders to ensure both move at the same speed to equalize the load and ensure the carriage remains level at all times, regardless of load placement.
The 21 Series VRC has a vertical rise of 22’ and can be used indoors or outdoors to move materials up to two levels.
Each 21 Series unit is customized to fit your space and vertical lift application needs.

Advanced safety features built into each 21 Series VRC
- Certified safety cams prevent carriage descent in the unlikely event of a chain failure
- Pressure switch prevents the carriage from drifting or sinking for a highly stable loading and unloading operation
- Velocity fuses prevent uncontrolled descent in the unlikely event of a hydraulic hose rupture
- Check valves hold the carriage in place in the event of
power loss
- Manual lowering valve allows carriage to be manually lowered to lowest level in the event of power failure or velocity fuse engagement
- Optional DeckLock Safety System provides added security at critical upper levels
- PFlow also offers a wide variety of gates and enclosures designed to meet your specific application
Features & Benefits
- The remote-mounted control panel and motor are pre-wired and ready for immediate installation
- The 21 Series’ carriage, whether a straddle or cantilever configuration, is lifted and lowered by chain over sprocket, actuated by guide column-mounted hydraulic cylinders. The cylinders are actuated by a remote mounted hydraulic pump.
- Optional quick-connect cabling for push-button stations, motor pump, and gate interlocks greatly reduces the field-wiring costs
- Optional hot-dipped galvanized or epoxy finish for outdoor or wash-down environments
