EnglishWhich Seegrid AMR Model Fits Your Material Handling Needs?
Updated
Seegrid's AMR fleet splits into two families: lift trucks (EL1, RS1, CR1) and a tow tractor (S7). The right pick depends on three numbers — payload, lift height, and travel distance — plus the physical layout of your facility. If you need to move pallets onto racks or conveyors, choose a lift model; if you need to pull cart trains over long routes, choose the S7.
Quick Comparison of the Seegrid Fleet
| Model | Best For | Max Lift Height | Payload Capacity | Standout Feature |
|---|---|---|---|---|
| Lift EL1 | Space-constrained warehousing, 3PL, large retail fulfillment | 5' 2" | 2,700 lbs | VDA 5050 interoperability-ready |
| Lift RS1 | Low-lift manufacturing and warehousing | 6' | 3,500 lbs | Industry-leading payload detection |
| Lift CR1 | Heavy manufacturing | 15' | 4,000 lbs | Ride-on compartment |
| Tow Tractor S7 | Warehousing, manufacturing, logistics | Not applicable (tugging) | 10,000 lbs | #1 U.S. market share in autonomous tow tractors |
Choosing by Application
Tight spaces and high-throughput fulfillment
The Lift EL1 is built for facilities where floor space is at a premium — 3PL operations and large retail fulfillment centers. Its 5' 2" lift height and 2,700 lb capacity suit inbound-to-putaway, pick/drop to wrappers or conveyors, cross docking, and outbound staging. If your site runs mixed fleets or plans to, the EL1's full VDA 5050 compliance matters: it's designed to interoperate with other vendors' equipment rather than locking you into one ecosystem.
General manufacturing and warehousing with low lifts
The Lift RS1 covers the middle ground: low-lift transport across industrial manufacturing and warehousing. It lifts to 6' and carries 3,500 lbs, with applications in buffer management, material transport, parts-to-line, outbound, and cross docking. Its differentiator is payload detection — useful when loads vary and you need the robot to verify what it's actually carrying before moving.
Heavy manufacturing and vertical handling
The Lift CR1 is the only model that reaches racking heights: 15' of lift and 4,000 lbs of capacity. That makes it the choice for heavy manufacturing, vertical handling, robotic cell integration, and parts-to-line delivery. It also includes a ride-on compartment, so a worker can travel with the robot for tasks that need a human present at the destination.
Long-haul tugging and cart trains
The Tow Tractor S7 doesn't lift — it pulls. With a 10,000 lb payload capacity, it handles long-haul cart train tugging, parts-to-line, replenishment, putaway, cross docking, and dunnage or trash removal. Seegrid notes this form factor is its most proven and battle-tested, holding the #1 U.S. market share in autonomous tow tractors. If your workflow is "move many carts a long distance" rather than "place a pallet on a rack," this is the starting point.
How Seegrid Frames the Decision
Seegrid positions all four models as part of one connected fleet, with the company providing consultation, project planning, route configuration, deployment, and ongoing support. The page does not publish pricing, so cost comparisons require a direct quote.
Two selection rules of thumb from the published specs:
- Match payload with margin. If your heaviest routine load is near a model's limit, step up a class — the CR1's 4,000 lbs and the S7's 10,000 lbs exist for a reason.
- Lift height decides the family. Anything above 6' rules out the EL1 and RS1; anything that's pure horizontal transport rules out all three lifts.
If you're still narrowing down, the fastest path is to list your three heaviest and three most frequent moves, then check which model covers both without exceeding its rated capacity.
