Series F Specifications

GENERAL

Pflow Series F Vertical Lifts move materials between two or more levels. Series F lifts feature four-corner support for heavy-duty, vertical material handling jobs. Principal components are guide columns, carriage and a mechanical actuating mechanism.

APPLICATION DATA

Please specify your application requirements:

Lifting Capacity:_____lbs.
Carriage Size:______"W x ______"L x _______"H
Vertical Rise:_____' ______"

NOTE: Series F Vertical Lifts are available with: Lifting capacities to 30,000 Ibs; Carriage sizes as required; Vertical rise to 200'. Standard travel speed is 20 fpm. Travel speeds up to 400 fpm are available on special order.

STRUCTURE

Guide columns are 6" wide flange. Carriage is fabricated of 6" or 8" structural members with deck plate. Other deck surfaces can be supplied.

OPERATION

Series F Vertical Lifts can be loaded/unloaded from all four sides. Carriage is lifted and lowered by roller chain attached to an electric motor-reducer assembly mounted on the guide columns. Power units employ 7-1/2 HP to 50 HP TEFC brake motors. Special sensing and guidance systems monitor lift chains.

ELECTRICAL

Standard power requirements are 208V/ 230V/460V, 3-phase. Control voltage is 110V. 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.

SAFETY FEATURES

Upward and downward travel of the carriage is limited by a limit switch. When the switch is tripped, the motor shuts off and the brake is engaged. Overload protection is provided by a relay that measures the motor current. If the current exceeds the amount required to move the maximum load, it will shut the unit down and engage the brake. Safety cams, mounted on each guide column, prevent uncontrolled descent in case both chains break. Chain tensioners and guides prevent chains from jumping on sprockets. NO RIDER signs are posted at each point of operation. Optional DeckLocks available.

CARRIAGE & SAFETY ENCLOSURES

Carriage is equipped with safety rails on nonoperating ends and safety chains or diagonal drop bars on operating ends. Optional expanded metal or sheet metal carriage enclosures are available. Mandatory safety enclosures provide guarding on all sides of the lift. Enclosures are a minimum of 8' high consisting of material which will reject a ball 3/4" in diameter. Gates are provided for access during loading and unloading. Gates are electrically and mechanically interlocked with carriage movement. Interlock prevents a gate from being opened unless the carriage is at the designated level. Interlock also prevents carriage movement if any gate is not fully closed and locked.

Series M Specifications

GENERAL

Pflow Series M Vertical Lifts move materials between two or more levels. Principal components are guide columns, carriage and a mechanical actuating mechanism.

APPLICATION DATA

Please specify your application requirements:

Lifting Capacity:_____lbs.
Carriage Size:______"W x ______"L x _______"H
Vertical Rise:_____' ______"

NOTE: Series M Vertical Lifts are available with: Lifting capacities to 8,000 Ibs; Carriage sizes to 10' x 12'; Vertical rise to 200'. Standard travel speed is 25-30 fpm. Travel speeds up to 400 fpm are available on special order.

STRUCTURE

Guide columns are 6" roll-formed or wide flange sections. Carriage is fabricated of 4" or 6" structural members with steel deck plate. Other deck surfaces can be supplied. Carriage is available in straddle or cantilever styles depending on application (see page 7 for more information).

OPERATION

Carriage is lifted and lowered by roller chain attached to an electric motor-reducer assembly mounted on the guide columns. Power units employ 2 HP to 25 HP TEFC brake motors. Special sensing and guidance systems monitor lift chains.

ELECTRICAL

Standard power requirements are 208V/ 230V/460V, 3-phase. Control voltage is 110V. 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.

SAFETY FEATURES

Upward and downward travel of the carriage is limited by a limit switch. When the switch is tripped, the motor shuts off and the brake is engaged. Overload protection is provided by a relay that measures the motor current. If the current exceeds the amount required to move the maximum load, it will shut the unit down and engage the brake. Dual safety cams prevent uncontrolled descent in case both chains break. Chain tensions and guides prevent chains from jumping on sprockets. NO RIDER signs are posted at each point of operation. Optional DeckLocks available.
