Greenfield plants get to design material handling first and build around it. Everyone else retrofits — into buildings full of piping, walkways, electrical runs, and equipment that isn’t moving. Retrofit conveyor projects succeed or fail on how honestly the design confronts the existing space.
Start With What Can’t Move
Before any conveyor gets specified, document the immovables: structural columns, headroom restrictions, existing process equipment, code-required egress paths, and crane or hoist access that maintenance depends on. A conveyor that blocks the route for pulling a centrifuge rotor hasn’t solved a problem; it’s created one on a delay.
Straight Lines Are a Luxury
Conventional conveyors want straight runs, and every direction change traditionally means a transfer point — another drive, another spill zone, another maintenance item. In a crowded plant, a three-transfer layout is common, and transfer points are where housekeeping problems live.
A path-following system changes that math. The Pathwinder conveyor turns, climbs, and descends as one continuous conveyor — a single belt, a single drive — following a route through the building rather than demanding the building accommodate straight lines. For retrofits, that frequently means one machine replacing what would otherwise be three conveyors and two transfer towers.
Structural Load and Support
Existing structures weren’t necessarily designed for new point loads. Serpentine and modular systems distribute support loads along the route and can often hang from existing steel with modest reinforcement. Get structural review early — support steel drives more retrofit cost variance than the conveyor itself.
Keeping the Plant Running During Installation
- Sequence installation around the process: most cake and screenings systems can be installed in sections during normal operation, with the changeover done in a planned short outage
- Prefabrication matters: systems that arrive in large, shop-assembled sections minimize field welding and installation days — Serpentix fabrication is done in-house, so sections arrive ready to set
- Plan the temporary handling path for the outage window before committing to a schedule
Getting a Retrofit Design Reviewed
The cheapest time to find a routing conflict is before fabrication. Serpentix offers a free engineering review for exactly this situation — submit your layout drawings and our engineers will evaluate routing options, support requirements, and installation sequencing against your actual constraints.
