Freight Class for Silo
To estimate your shipment, use the Silo Freight Class Calculator.
The Silo Freight Class Examples use the current 13-tier density scale, effective July 19, 2025, and range from Class 70 to 250.
These are density-based estimates.

Silo shipment comparison
Silo Freight Class by Shipment Format
Silo freight class can change with the vessel diameter and length, support frame or saddles, nozzles, protective clearance, and top-load restrictions. Use the finished packaged dimensions and total weight rather than the equipment's unpackaged size.
| Silo shipment | Typical packaging | Density tendency | Stackability | Planning note |
|---|---|---|---|---|
| Compact silo section | Reinforced pallet or skid with blocking, restraint, and weather protection | Medium to higher | Limited | Dense hopper or lower cone secured to a frame; this example calculates to 18.75 lb/cu ft and Class 70. |
| Crated silo module | Framed crate with internal restraint and protection for controls and moving parts | Medium to lower | Possible with engineered crate | Shell, cone, fittings, and supports protected; this example calculates to 6.51 lb/cu ft and Class 125. |
| Large empty silo section | Elongated or oversized crate with structural bracing and protective clearance | Lower | Usually non-stackable | Tall lightweight shell using broad non-stackable space; this example calculates to 3.65 lb/cu ft and Class 250. |
| Vessel with drive, fittings, and support frame | Main vessel or tank plus separately protected agitator parts, instruments, valves, legs, and controls | Varies | Usually limited | Large empty vessels can occupy substantial cubic space even when their packaged weight is moderate. |
Silo shipping options
Choosing a Shipping Method for Silo
The appropriate service depends on finished dimensions, packaged weight, piece count, loading method, value, stackability, and whether specialized handling is required.
| Silo shipment | Common shipping option |
|---|---|
| Compact silo section | LTL with handling review or volume service |
| Crated silo module | Standard LTL with packaging and handling review |
| Large empty silo section | LTL or volume service with weight and handling review |
| Vessel with drive, fittings, and support frame | LTL, volume, partial truckload, or dedicated service after piece-count and handling review |
Heavy, long, high-value, non-stackable, multi-piece, or rigging-dependent silo shipments may need carrier review before booking.
Silo Packaging, Stackability, and Damage Risk
Silo Packaging
- Support the vessel, mixer, or shaft on engineered saddles, frames, or skids that prevent rolling and point loading.
- Cap nozzles, ports, manways, instruments, and fittings and brace long shafts or projecting drives.
- Protect shells, linings, coatings, nameplates, load cells, controls, and polished product-contact surfaces.
Silo Stackability
- Treat round vessels, tall tanks, open frames, and projecting nozzles as non-stackable.
- Use structural framing rather than the shell or vessel roof to carry any load above the shipment.
- Mark sling points, center of gravity, upright orientation, and areas where forks must not enter.
Silo Fragility and Liability
- Prevent rolling, shell distortion, nozzle damage, coating abrasion, and movement of internal components.
- Drain or secure approved contents and document cleaning or contamination-control requirements.
- Confirm declared value and specialized handling for pressure-rated, lined, polished, or custom-fabricated equipment.
Before Requesting a Silo Freight Quote
How to Measure a Packaged Silo Shipment
- Measure after the silo is secured and all pallet, skid, crate, framing, guards, and protective materials are complete.
- Include runners, saddles, legs, controls, fittings, attachments, overhang, and every projecting packaged component.
- Measure to the longest, widest, and tallest finished point and use the total tendered shipment weight.
Silo Freight Quote Checklist
- Record the finished packaged length, width, height, and total weight.
- State whether the shipment is stackable and whether top loading is prohibited.
- Include photos showing packaging, securement, labels, lift points, and exposed risk areas when practical.
- List detached controls, guards, accessories, tooling, fittings, and other separate pieces.
- Confirm forklift, dock, crane, rigging, liftgate, or specialized loading requirements.
