Case study - packhouse conveyor retrofit

Gooseneck tray feeder retrofits for packhouse lines.

A family of gooseneck conveyor and tray feeder layouts developed for various packhouse retrofit conditions, including multi-drop arrangements, single feeder variants, reject line interfaces and fabrication-ready profile work.

Retrofit scope

Make tray feeding fit the line that already exists.

Packhouse retrofits are rarely clean-sheet projects. The gooseneck tray feeder work was about fitting useful conveyor geometry into existing packhouse constraints while keeping access, drop positions, reject flow and fabrication logic under control.

01

Gooseneck geometry

Tray feeder conveyor profiles shaped to lift, drop and transfer product or trays through awkward height and line constraints.

02

Multi-drop layouts

Packhouse layouts developed around repeated feeder drops, centre spacing options and the surrounding production line.

03

Single feeder variants

Single gooseneck units and handed details shaped for smaller retrofit points or isolated line modifications.

04

Fabrication package

DXF profiles, fabricated parts, folded tray sections, brackets, legs, rollers and BOM logic prepared for build and installation.

Engineering approach

Retrofit design is constraint management.

The work sits between layout, product flow and fabrication. The useful detail is in centre spacing, leg positions, electrical box clearances, reject tray paths, roller locations, folded profiles and the parts that make the design installable without turning the existing line upside down.

Outcome

A repeatable retrofit platform for tray feeder work.

The result was a practical design set for gooseneck tray feeder retrofits across packhouse layouts: repeated enough to fabricate efficiently, flexible enough to adapt to spacing, reject line and site constraints.

A

Packhouse fit

The conveyor layouts worked around existing line spacing and retrofit constraints.

B

Fabrication ready

The drawing set supported DXF cutting, folding, brackets, rollers and assembly detail.

C

Variant aware

Multi-drop, single gooseneck and reject line options were treated as related design variants.

Have a retrofit conveyor problem inside an existing line?

Send the line photos, centre spacing, target drops, product path and constraints. We will start with layout logic, then make it buildable.
