GENERAL
Pflow Series D 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 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 20 fpm.
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
cantilever style and may be loaded from any one of three
operating sides depending on application.
OPERATION
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
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 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 & 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 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.
CODE GUARANTEE
Pflow Industries, Inc. provides a written guarantee of
compliance with all federal, state and local codes. Pflow
vertical reciprocating conveyors (VRC's) and continuous
reciprocating conveyors (CVC's) are designed, installed and
guarded in accordance with ANSI/ASME B20.1 (current edition) and
National Electric Code.

SUBMITTALS
Pflow Industries provides general arrangement drawings detailing
your specific application including plan and elevation views
with dimensional information, equipment specifications, and
guarding requirements. An Owners Manual with complete parts
list, recommended spare parts list, maintenance instructions and
troubleshooting guide is also provided.
INSTALLATION
Comprehensive installation instructions and electrical
schematics are provided for proper installation of Pflow
vertical reciprocating conveyors. Pflow will also provide
technical support so that equipment is properly installed and
guarded per ANSI/ASME B20.1 to ensure safe, efficient operation.
CANTILEVERED CARRIAGE
The carriage is cantilevered to allow loading/unloading from the
side. With cantilevered carriages, the support columns are
placed on one side of the carriage to allow loading/unloading at
90° angles. This requires heavier structure and guide wheel
components. Carriage size and capacity are limited by the
unbalanced load condition. With large carriages or high capacity
applications, the carriage thickness is increased thereby
requiring a deeper pit for proper installation.
