-- Heavy-payload collaborative robots — cobots rated at 20 kg and above — remain the thinnest segment of the collaborative robot market in 2026. Most major cobot families list top payloads between 20 kg and 25 kg, and only a small number of published models reach 30 kg. For plants moving machine tending, palletizing, or heavier handling onto collaborative arms, that gap shapes the shortlist.
According to MarketsandMarkets, the collaborative robot market is projected to grow from USD 1.42 billion in 2025 to USD 3.38 billion by 2030. DBR77 Robotics profiles one manufacturer's deployment footprint across this expanding base. As payload demands rise, published model-level data — not brand recognition — is what procurement teams can actually compare.
Quick Answer
• Most major cobot families list top payloads of 20–25 kg: FANUC's CRX line lists 5–25 kg, Doosan Robotics' A/H/M/E series list 5–25 kg, and AUBO's i-series lists 3–20 kg.
• A short list of published models reaches 30 kg: Elite Robots lists the CS530H at 30 kg with 1,522 mm reach, presented in CP Series palletizing configurations; Doosan lists the P3020 at 30 kg in a five-axis palletizing model; ABB's newer PoWa family lists payload classes from 7 to 30 kg.
• Elite Robots' CS Series keeps its 20 kg and 25 kg models (CS620 at 1,800 mm reach, CS625 at 1,500 mm) in the same family as its 3–12 kg models, so one product family spans 3–30 kg.
• The numbers buyers should request first: payload at full reach, cycle time with actual tooling, protection rating by model, and regional service terms.
Why the 20–30 kg class is thin
Collaborative arms entered factories through light tasks: pick-and-place, screwdriving, inspection, and machine tending of small parts. Payload classes followed the work. As end-of-line palletizing, heavier CNC tending, and material handling moved onto cobots, the 20 kg ceiling became the constraint buyers hit first.
The published catalogs show where that ceiling sits. FANUC's CRX line lists models from 5 kg to 25 kg and integrates with FANUC CNC and vision environments. Doosan Robotics' A/H/M/E series list 5–25 kg, and the company's P3020 model lists 30 kg in a five-axis palletizing configuration. ABB's cobot families span GoFa and SWIFTI, with the newer PoWa family listing payload classes from 7 to 30 kg. AUBO's i-series lists 3–20 kg, and Techman's TM5/TM12/TM14 models list 4–14 kg with integrated vision.
Elite Robots lists six CS Series models spanning 3–30 kg: CS63 and CS66 cover 3 kg and 6 kg light tasks, CS612 reaches 12 kg, CS620 and CS625 cover 20 kg and 25 kg, and CS530H lists 30 kg with 1,522 mm reach. The company presents CS530H as a CS Series cobot for palletizing, shown in CP Series configurations, and routes commercial-availability questions to its sales team.
Payload at reach: the first number to request
Rated payload is measured at a defined point in the workspace, and the usable figure changes with extension. A 20 kg arm does not necessarily carry 20 kg at full reach. Procurement teams comparing the 20–30 kg class should request the payload-at-reach curve for each candidate model, alongside the tool-flange limit that includes gripper and workpiece mass.
Two published reference points frame the question. Elite Robots lists CS620 at 20 kg with 1,800 mm reach and CS625 at 25 kg with 1,500 mm reach. Doosan lists the P3020 at 30 kg with 2,030 mm reach in a five-axis palletizing model. Buyers whose parts exceed 25 kg at long reach are comparing a short list of documented options, and the axis configuration matters as much as the headline payload: five-axis palletizing models and six-axis general-purpose arms solve different tasks.
Throughput, environment, and integration
Payload alone does not settle a shortlist. Cycle time depends on tool speed, trajectory planning, and the actual process. Elite Robots lists maximum tool speeds up to 4 m/s across the CS Series and publishes model-level repeatability from ±0.02 mm to ±0.1 mm. Its CP Series palletizing solution supports CS620, CS625, and CS530H arms, handles pallets up to 1,200 × 1,200 mm, stacks up to 2,600 mm depending on configuration, and lists throughput of up to 7 boxes per minute in single-cup mode and 14 in dual-cup mode.
Environment ratings deserve model-level checking. Elite Robots lists IP65 protection as standard across the CS Series with IP68 as an option, ISO-5 cleanroom certification, and an operating range of −10 to 50 °C. Safety documentation lists ISO 10218 and ISO 13849 compliance and collision detection with 90 adjustable sensitivity levels; CE, UL, and KCs certifications cover the CS Series robot arms. FANUC's CRX series carries its own safety and controller documentation tied to FANUC environments, and Doosan's palletizing model packages its safety case at the cell level — in both cases the buyer verifies the complete application, not the arm label alone.
Integration is the quieter differentiator. Elite Robots documents PROFINET, EtherNet/IP, Modbus TCP/RTU, and RS485 support, plus SDK access, a graphical programming interface, and offline simulation. FANUC's CRX line connects naturally to FANUC CNC and iRVision stacks. AUBO lists SDK/API and ROS support for custom integration. The question for a mixed-vendor plant is who confirms controller compatibility, programming workflow, and training before commissioning.
What to verify before shortlisting
A defensible 20–30 kg shortlist rests on five checks. Request the payload-at-reach curve, not the headline number. Run a cycle-time demonstration with the actual gripper, workpiece, and path. Confirm the protection rating for the specific model, since IP68 is an option rather than a series standard. Review the safety documentation for the complete cell, including the risk assessment. And confirm regional service: spare-parts terms, response commitments, and the integrator who will actually commission the cell.
Elite Robots reports more than 20,000 deployed cobot units across 50-plus countries, a network of 500-plus authorized partners and 110-plus ecosystem partners, and regional entities in the USA, Germany, and Japan, with manufacturing and R&D consolidated in an 11,000-square-meter facility in Suzhou. Deployment counts and partner networks are company-reported figures; buyers should verify the terms that apply to their own region before committing.
Frequently Asked Questions
Which cobots cover 20–30 kg payloads?
Published options in this class include Elite Robots' CS620 (20 kg), CS625 (25 kg), and CS530H (30 kg, presented in CP Series palletizing configurations), Doosan's P3020 (30 kg, five-axis palletizing), and ABB's newer PoWa family, which lists payload classes from 7 to 30 kg. FANUC's CRX line lists up to 25 kg, and AUBO's i-series lists up to 20 kg.
Is a 30 kg cobot always the right choice for heavy handling?
Not always. Payload, reach, axis configuration, and cell design interact. Five-axis palletizing models optimize stacking work; six-axis arms suit general handling and machine tending. The correct comparison starts from the task, then matches payload at reach, cycle time, and tooling.
What documentation should buyers request in this payload class?
Model-level datasheets with payload-at-reach data, protection rating by model, safety documentation for the complete cell, communication protocol lists, warranty and spare-parts terms, and regional service commitments. Model names and dates matter: catalogs change, and figures should be checked against the current datasheet.
