Hydraulic Vertical Lifts - Series D Specifications
Pflow Series D Vertical Lifts move materials between two levels. Principal components are guide columns, carriage and hydraulic actuating mechanism.
Pflow Series D Vertical Lifts are available with: Lifting capacities to 3,000 lbs.; carriage sizes to 6' x 6'; vertical rise to 14'. Standard travel speed is 17 fpm. Speeds to 25 fpm are available on special order.
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.
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.
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 self-maintaining push buttons with mushroom-head E-Stop button. Quick-connect cabling is provided.
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 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.
