Span Tech: The Designer System

WG-Series (Wedge Unit)

The WhisperTrax WG-Series Wedge unit is designed to move product vertically up or down. The Wedge is a classic all-mechanical design, requiring no sensors or computer interface and offering the simple reliability of all-mechanical movement; it grabs the parts on the sides, and off they go. All products in a given production run must be the same size and must be rigid, like cartons or other containers. The Wedge Units are available in two models: the MiniLink for lightweight products, and the MultiSpan for heavier products.

	WG-MIN MiniLink: The WhisperTrax WG-MIN MiniLink Wedge Conveyor, with its 2.36” (60mm) wide, 0.4” (10mm) Brush-Top Polyurethane chain, is ideal for small products. The MiniLink Wedge can accommodate a range of lightweight products, from 1” (25.4mm) to 10” (254mm) in height. Product width is adjustable from zero to 12” (305mm). The conveyor uses an all stainless steel “I-Beam” frame, eliminating plastic wear strips and providing a cleaner, washdown-tolerant design.

	WG-MUL MultiSpan: The WhisperTrax WG-MUL MultiSpan Wedge Conveyor, featuring both Santoprene and Polyurethane chain, is ideal for larger, heavier products. The MultiSpan Wedge can accommodate product sizes from as small as 2” (51mm) up to 24” (610mm) in height. Product width is adjustable from zero to 24” (610mm).

Positionable or Adjustable The MiniLink and the MultiSpan Wedge Conveyors are both offered in a standard “positionable” version and an optional, fully adjustable version. The positionable unit is designed to be set for a single product width and then manually locked in that position. The fully adjustable unit can accommodate a variety of product widths by a few turns of the handwheel.
