01 / What We Fabricate
Mechanical Structures Between an AMR Base and Its Payload
An AMR top-module frame connects a released mobile base to the conveyor, lift, tote rack or process fixture above it. The fabrication plan must preserve the buyer-defined chassis pattern, payload interfaces, cable zones and service access after welding, finishing and hardware installation.
Lift Module Supports
Frames and decks built around released actuators, guides, maintenance clearances and load paths.
Rack and Tote Structures
Payload supports, shelves, stops and brackets supplied as drawing-controlled mechanical kits.
Custom Payload Decks
Platform plates, subframes and equipment mounts for project-specific AMR process modules.
Our scope: build-to-print AMR top-module frame fabrication
DRAmetal manufactures the released frame, deck, plates, brackets, covers, hardware and agreed mechanical kit. The AMR OEM or integrator owns load cases, structural design authority, center of mass, vehicle stability, motion, docking, controls, guarding, functional safety and final machine validation.
02 / AMR Payload Structures
Top-Module Frames for Conveyor, Lift and Tote Applications

06
FAI and Variant Packout
Inspect agreed chassis-to-payload CTQs and group the completed kit by module revision.
05 / Why It Matters
Why AMR Top Modules Need Their Own Datum Strategy
The top module is not the AMR chassis. It is the controlled mechanical bridge between the mobile platform and its task-specific payload, so its sourcing route should not compete with a general chassis page.
Chassis Relationship
The released mounting plane and pattern must remain traceable through weld fixture setup and final inspection.
Transfer Interfaces
Conveyor or lift handoff geometry can depend on installed relationships that loose-part inspection does not capture.
Service Access
Covers, fasteners, motors, sensors and cable paths need buyer-defined removal and maintenance envelopes.
Module Variants
Similar frames can carry different payload plates, stops or brackets, making revision and packout control essential.

Why Robotics OEMs Use DRAmetal for AMR Module Metalwork
01
Coordinated frame-and-deck route
Tube frames, formed decks, machined plates, brackets, hardware and finish are reviewed as one released package.
02
Interface-focused DFM
Reviews prioritize chassis, payload and service datums instead of treating every outside edge as equally critical.
03
RFQ-defined inspection
First-article evidence can follow the buyer's approved datum hierarchy, support condition and acceptance plan.
04
Revision-controlled kits
Module variants and approved loose items can be identified and packed by platform, payload and drawing revision.

09 / FAQ
AMR Top-Module Frame FAQ
What AMR top-module parts can you manufacture?
Typical build-to-print scope includes welded support frames, payload decks, machined interface plates, brackets, covers, cable supports, guards and drawing-defined hardware kits.
Is an AMR top module the same as an AMR chassis?
No. The chassis is the mobile base structure. A top module is the task-specific structure mounted above it for a conveyor, lift, tote rack, fixture or other payload.
Do you calculate payload capacity or AMR stability?
No universal load or stability claim is implied. The OEM or integrator supplies released load cases, center-of-mass limits and approved geometry and owns final vehicle validation.
Can you inspect the frame after welding?
Yes, when quoted. Agreed checks can cover the chassis pattern, payload planes, transfer height, guide or actuator mounts, hardware and other released CTQs using the specified support condition.
What should an AMR top-module RFQ include?
Send 3D models, 2D drawings, chassis interface, payload and purchased-component envelopes, load inputs approved by the design owner, datum scheme, materials, finish, hardware, inspection plan, variants and quantities.
