Equipped with patented safety features, Series 21 Vertical Lift provides efficient, vertical material handling, transporting materials between two levels. It is adaptable to mezzanine, through-floor, interior, or exterior applications.

Accommodating loads up to 6,000 lb, Series 21 is available with carriage sizes to 10 x 10 ft. The carriage, available in straddle or cantilever styles, is hydraulically lifted and lowered from level to level. Lift has 6 in. wide flange guide columns that are 66% heavier than other vertical lifts on the market, and oversized bearings and heavy roller chain to ensure long-lasting performance.

A heavy torsion bar links the two hydraulic lift cylinders to equalize the load, eliminate carriage twisting, and relieve stress on guides, columns, and carriage, so that the carriage remains level at all times for smooth, efficient operation. Dual spring-loaded safety cams provide added protection against uncontrolled descent. Series 21 can also be equipped with Pflow's patented DeckLock system, which automatically locks the carriage into place at the critical upper levels and eliminates carriage bounce or drift.

Standard safety features that meet or exceed code requirements include:

• 8 ft high mesh enclosures


• safety gates at each level


• safety chains and railings


• overtravel protection


• backstop panels


• remote, heavy-duty control stations.

All safety gates are electrically and mechanically interlocked with carriage movement and lift operation. Velocity fuses prevent uncontrolled carriage descent in case of a total hydraulic hose rupture.

All Pflow lifts meet or exceed ANSI/ASME B20.1 code. Pflow provides total engineering, fabrication and installation services and guarantees code approval in every state.
