Series DB Specifications

GENERAL

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


APPLICATION DATA

Please specify your application requirements:

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

NOTE: Series DB Vertical Lifts are available with: Live load lifting capacities to 100 Ibs. Carriage sizes to 36" x 36". Vertical rise to 50'. Standard travel speed is 60 fpm. Travel speeds up to 400 fpm are available on special order.


STRUCTURE

Frame is designed to be self-standing and constructed of structural steel tube. Carriage is typically supplied with roller conveyor deck. Carriage is cantilever style and may be loaded from any one of three operating sides depending on application. see page 7 for information on carriage styles.


OPERATION

Carriage is lifted and lowered by timing belt attached to an electric motor-reducer assembly mounted on the frame. Power unit employs a 1/2 hp TE brake motor mounted to the top of lift frame.


ELECTRICAL

Standard power requirements are 208V/ 230V/460V, 3-phase. Control voltage is 110V. Control panel is designed to be mounted to the back of the frame. Push buttons are mounted in the panel door to allow manual control only.


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 current sensor 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.


CARRIAGE & SAFETY ENCLOSURES

Safety guarding on all sides of the lift is available. Guarding is a minimum of 8' high consisting of material which will reject a ball 3/4" in diameter.

Series FM Specifications

GENERAL

Pflow Series FM Vertical Lifts move materials between two levels. Principal components are guide columns, carriage and hydraulic actuating mechanism.

APPLICATION DATA

Please specify your application requirements:

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

NOTE: Series FM Vertical Lifts are available with: Lifting capacities to 6,000 Ibs; Carriage sizes to 8' x 8'; Vertical rise to 20'. Standard travel speed is 18 fpm. Travel speeds up to 25 fpm are available on special order.

STRUCTURE

Guide columns are 6" roll-formed 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 (see back page for more information on carriage styles).

OPERATION

Carriage is lifted and lowered 6y direct-acting hydraulic cylinders operating in a pull mode. Cylinders are actuated by o remote mounted hydraulic pump. Transmission of the lifting force is direct from the top of the columns to the carriage using a TruPull cylinder. FM Lift has no cables, chains or other flexible lifting means that require safety cams to prevent
unintentional descent of carriage.

ELECTRICAL

Standard power requirements are 208V/ 230V/460V, 3-phase. 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.

SAFETY FEATURES

Upward travel of the carriage is limited by positive mechanical stops that assure positive leveling with the upper deck. Redundant overload protection is provided to positively prevent raising of the carriage if loaded to more than 110% of rated capacity. Velocity fuses prevent uncontrolled descent in case of hydraulic hose rupture. NO RIDER signs are posted at each point of operation. Optional DeckLocks available.

CARRIAGE & SAFETY ENCLOSURES

Carriage is equipped with safety rails on non operating 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.
