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 lbs; 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

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.
CARRIAGE & SAFETY
ENCLOSURES
Carriage is equipped with safety
rails on non-operating ends and safety chains, diagonal drop
bars or gates 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 2" in diameter. Gates are provided for access
during loading/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.

vertical reciprocating conveyors (VRC's) and continuous
