21 Series Vertical Lift

Hydraulic Vertical Lifts – 21 Series

A LEVEL CARRIAGE REGARDLESS OF LOAD PLACEMENT

The 21 Series vertical reciprocating conveyor (VRC) from PFlow Industries is a two-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.

Standard safety features, including check valves and safety cams, are built into the 21 Series custom hydraulic lift.
