| Description | Series 21 Lift Provides Efficient, Safe Vertical Handling For Loads Up To 8,000 lbs. | Series D Lift Offers High Quality, Safety, And Low Maintenance. Also Features Exclusive Dual-Pak Design. | ||
| General Specifications | Pflow Series 21 Vertical Lifts move materials between two levels. Principal components are guide columns, carriage and hydraulic actuating mechanism. | Pflow Series D Vertical Lifts move materials between two levels. Principal components are guide columns, carriage and hydraulic actuating mechanism. | ||
| Application Data | Pflow Series 21 Vertical Lifts are available with: Lifting capacities to 8,000 lbs.; carriage sizes to 10' x 10'; vertical rise to 22'. Standard travel speed is 24 fpm. Speeds to 35 fpm are available on special order. | Pflow Series D Vertical Lifts are available with: Lifting capacities up to 3,000 lbs.; carriage sizes to 6' x 6'; vertical rise to 15'. Standard travel speed is 17 fpm. Speeds to 25 fpm are available on special order. | ||
| Structure | Guide columns are 6" wide flange. Carriage is fabricated of 4" or 6" structural members with steel deck plate. Other dec surfaces can be supplied. Carriage is available in straddle or cantilever styles. | Guide columns are 6" wide flange sections. Carriage is fabricated of 4" or 6" structural members with steel deck plate. Other deck surfaces can be supplied. Carriage is cantilever style and may be loaded from any one of three operating sides depending on application. | ||
| Operation | Carriage is lifted and lowered by two hydraulic cylinders mounted on guide columns. Cylinders are actuated by a remote mounted hydraulic pump. Transmission of the lifting force is through roller chain attached to the cylinders and carriage. A torsion bar links the two cylinders to equalize the load and ensure carriage remains level at all times. | Carriage is lifted and lowered by direct-acting hydraulic cylinders. Cylinders are actuated by a remote mounted hydraulic pump. Transmission of the lifting force is direct from the base of the columns to the carriage using a Dual-Pak ram. | ||
| Electrical Arrangement | Standard power requirements are 208V/230V/460V, 3-phase. Single-phase is an available option. Control voltage is 24V. Control stations and remote mounted control panel are NEMA 12. Control stations, provided for each level, include selfmaintaining push buttons with mushroom-head E-Stop button. Quick connect pre-wiring is available as an option. | Standard power requirements are 208V/230V/460V, 3-phase. Single-phase is an available option. Control voltage is 24V.

| Safety Features | Overtravel is prevented by positive mechanical stops. Safety cams prevent uncontrolled descent in case both chains break. Velocity fuses prevent uncontrolled descent in case of hydraulic hose rupture. NO RIDER signs are posted at each point of operation. Optional DeckLocks automatically lock carriage at the upper level to eliminate drift or bounce. Carriage will not move if loaded to more than 120% of rated capacity. | Upward travel of the carriage is limited by positive mechanical stops that ensure positive leveling with the upper deck. Redundant overload protection is provided to positively prevent raising of the carriage if loaded to more than 120% of rated capacity. Velocity fuses prevent uncontrolled descent in case of hydraulic hose rupture. NO RIDER signs are posted at each point of operation. | ||
| Carriage Side Guards | Carriage is equipped with safety rails on non-operating sides and safety chains or diagonal drop bars on operating ends. Optional expanded metal or sheet metal carriage side guards are available. | |||
| Safety Enclosures | Safety codes (ANSI/ASME B20.1) require gates and enclosures on all sides of the lift. Enclosures must be a minimum of 8' high and reject a ball 2" in diameter. Pflow manufactures gates and enclosures with 1/2" expanded metal in a structural angle frame. Gates are accessible during loading/unloading and are electrically and mechanically interlocked with carriage movement. Interlocks prevent gates from being opened unless the carriage is at the designated level and also prevent carriage movement if any gates are not fully closed and locked. | |||
| Options |
As an option, the Pflow Series D Lift can be shipped as a self-contained unit equipped to service in-plant mezzanines. The Pflow Series D Mezzanine Lift is preassembled and shipped with lower-level enclosures and code-approved safety gates. The lift motor pump and controls are pre-wired for fast, easy, one-day installation. |
