VALUATION CHARGES. Transportation charges assessed shippers whose shipments have declared values higher than the historically assumed value to 50 cents a pound or 50 dollars, whichever is greater.

VALUE-ADDED SERVICES (IN A WAREHOUSE). Special services (other than merely filling a customer's order), performed in a warehouse as required by the customer.

VARIABLE REACH LIFT TRUCK. A high lift truck with the additional capability of extending and retracting the forks (and load) in a longitudinal direction.

VAULT. A room designed to provide security of contents.

VERTICAL BAR CODE. A code pattern presented in such orientation that the overall coded area from start to stop is perpendicular to the horizon.  The individual bars are in an array appearing as rungs of a ladder.

VERTICAL BELT CONVEYOR. A vertical conveyor in which sections of articulated slat conveyor apron form rigid platforms for vertical movement in continuous flow. The platforms are flexible in but one direction and they assume a vertical position on the noncarrying run to minimize space requirements.

VERTICAL CHAIN CONVEYOR, OPPOSED SHELF TYPE. Two or more vertical elevating-conveying units opposed to each other. Each unit consists of one or more endless chains whose adjacent facing runs operate in parallel paths. Thus each pair of opposing shelves or brackets receive objects (usually dish trays) and deliver them to any number of stations.

VERTICAL CLEARANCE. The dimension from the floor to the underside of the rail assembly; or from the topside of the rail assembly to the underside of the next rail assembly.

VERTICAL LIFT MODULE. A modular storage and retrieval device similar to a mini-load, which stores product vertically on special trays, retrieving them and presenting these trays of items to be picked at a pickstation.

VERTICAL RECIPROCATING CONVEYOR. A reciprocating power or gravity actuated unit which receives only inanimate objects on a track, roller, conveyor, or power conveyor forming the bed of the carrier and transmits these inanimate objects vertically from one elevation to another. This type of conveyor is never designed to carry an operator or passengers and no person may ever be permitted to ride upon it. The carrier must never be furnished with flooring of any type which might provide safe footing for any person. The conveyor shaft must be enclosed and where manual loading and unloading is employed, doors at each operating level must be installed and so interlocked with the carrier that doors at any level can be opened only when the carrier has stopped at that level and carrier cannot be moved until such open doors are closed. No controls for movement of carrier may be located on carrier, or within the enclosure, or within reach of any person standing on the carrier. For further reference see the current B 20 Safety Code for “Conveyors & Related Equipment.”

VIBRATING CONVEYOR. A trough or tube flexibly supported and vibrated at a relatively high frequency and small amplitude to convey bulk material or objects. (See OSCILLATING CONVEYOR.)

VIBRATING CONVEYOR, BALANCED. A vibrating conveyor having a secondary mass operating in a direction opposite to the movement of the troughed pan for the purpose of minimizing the dynamic force normally directed into the supports.

VIBRATING CONVEYOR, NATURAL FREQUENCY. A vibrating conveyor in which the rate of free vibration of the trough on its resilient support is approximately the same as the rate of vibration induced by the driving mechanism.
