PFast PFact:

PFlow has its own fast dry, acrylic enamel paint named "PFlow Blue.


Vertical Reciprocating Conveyor Glossary

"C" LOAD PATTERN: Carriage configuration leaving opening on one side only.

"Z" LOAD PATTERN: Carriage configuration leaving opening on opposite sides of deck.

"90 ..." LOAD PATTERN: Carriage configuration leaving openings at right angles.

ASME: American Society of Mechanical Engineers.

BACKSTOP PANEL: 48" high minimum expanded-metal safety enclosure welded to the lift columns during installation to create an additional carriage side guard during mezzanine loading operations. May be attached to upper mezzanine itself on cantilever applications.

CDLR: Chain driven live roller; conveyor section mounted on an open-deck carriage to transfer load on/off VRC.

CEMA: Conveyor Equipment Manufacturers Association.

CANTILEVER DESIGN: Both columns are on the backside of the carriage - used for 90º loading, overhead height restrictions, or space restrictions.

CARRIAGE: The usable part of the lift where product is loaded.

CHAIN TENSIONER: This device attaches a limit switch directly to the chain. The device monitors the chain's tautness while the limit switch shuts off the drive base if the chain becomes too tight or slack.

COLUMNS: The vertical members on which the carriage travels up/down on.

COLUMN SPLICE: Columns are shipped in more than one piece. Field welding required.

CONSTANT PRESSURE: Refers to a push button station that requires the operator to maintain pressure on desired mode until carriage reaches selected level.

DECK: The floor of the carriage or platform (can be smooth, tread plate, or open).

DELIVERY: Normally eight to ten weeks after return of approved drawings.

DIAGONAL DROP BAR: Load-defining steel bar and safety chain across operating end(s) of carriage to prevent load movement.

DRIVE BASE: Gear reducer brake motor that powers the chain that lifts and lowers the carriage. This assembly is mounted at the top of the lift columns.

DROP TEST: State code requirement to demonstrate safety cam operation. Carriage is loaded to rated capacity. Chains are slackened by supporting carriage in an elevated position. Support is then pulled out allowing the carriage to drop proving safety cams engage.

EFFECTIVE WIDTH/LENGTH: Refers to usable space on the carriage; overall dimensions include side guards.

ENCLOSURES: Code-required 8'-0" high safety fencing on all floor levels, which prevents people from entering the lift area. Can be expanded metal, block, drywall, wire, etc. and must resist a 2" ball.

EPOXY COATING: Abrasion-resistant, two-part, industrial-strength protective coating system applied over sandblasted and primed steel. It is ideal for outdoor, chemical, or caustic wash-down environments or applications where standard alkyd enamel is viewed as insufficient.

GENERAL ARRANGEMENT (GA) DRAWING: The drawing produced by PFlow Industries, which only shows our lift, gates, and enclosures. It does not show building details.

HEADER: This refers to horizontal structure spanning the width of the carriage/gate; defines load height on straddle units.

HOLLOW SHAFT: Shaft of the reducer of our mechanical drive base penetrates brake motor rather than coupling to it. This minimizes wear points.

HYDRAULIC POWER UNIT: Refers to motor, pump, and reservoir assembly. Reservoir is shipped with oil. (Most hydraulic power units come with the control panel attached and hydraulic power unit pre-wired to the control panel.)

INTERLOCK: An integral electro/mechanical device that prevents access gates or doors from opening when the carriage is not present and prevents lift from operating if gate is open and carriage is present.

INTERMEDIATE STOP: Any stop between the lowest floor and highest stopping point.

KD - KNOCKDOWN: Carriage shipped in pieces. Field welding is required.

KEY LOCK CONTROL: A keyed push button station that prevents unauthorized use.

KICK PLATE: A curb on the outermost edge of the inoperable sides of the deck to contain product and is normally 4" high.

LIFT PRESENT LIGHT: Light on push button station, which alerts the operator that the carriage has arrived at that level's position.

LOAD HEIGHT: Maximum height of product; nominally 7'-0" to fit under standard gate/carriage headers.

LOAD TEST: Carriage is loaded to rated capacity, and the lift is operated.

MOMENTARY CONTACT: Refers to push button station that permits operator to touch and release desired mode while carriage travels to selected level automatically.

OVERALL DIMENSION: The outside dimension of the deck or entire lift.

PIT: A depression in the floor usually 1" deeper than the carriage profile, which allows the deck to rest flush at floor level.

PNEUMATIC GATE OPERATOR: An automatic gate opener, which requires in-plant, clean, dry air, minimum 60 psi. Can be operated by either pull cord or push button controls.

ROLL OFF PANEL: See Backstop Panel.

SAFETY CAMS: Spring-loaded, hardened steel cams directly attached to chain that engages if chain breaks, preventing carriage from dropping more than a few inches.

SIDE GUARDS: A protective enclosure on the outermost edge of the inoperable sides of the deck welded to the carriage to contain load. Can be rails, sheet steel, or expanded metal.

SPECIAL ALKYD PAINT: A fast-drying enamel paint, color-mixed per the customer's request, and applied using standard PFlow methods.

STRADDLE DESIGN: Beams are midpoint of the carriage on each side which offers even distribution of weight on components.

T.O.R.: Abbreviation for top of roller; refers to load elevation in conveyor system.

UPRIGHTS: The portion of the carriage that houses the wheels that guide the carriage in the columns.

VELOCITY FUSE: Device to restrict flow of hydraulic fluid in the event of hose rupture.

VERTICAL TRAVEL: Distance carriage travels; floor-to-floor or total distance.
