Heavy-Duty Series
RL Robotics Heavy-Duty Series is a high-payload range of 6-axis industrial robots engineered for large-scale, demanding automation. With payload capacity from 125kg to 500kg and reach spanning 2658mm to 3100mm, these robots solve the endurance problem — built for press lines, structural fabrication, and continuous multi-shift environments where the robot is a core production asset, not a supplementary one. The hollow-arm architecture protects internal cables from sparks and abrasion, while IP67-rated wrist protection and ±0.06mm repeatability deliver precision even under sustained heavy loads.

What is the Heavy-Duty Series industrial robot used for?
RL Robotics 6-axis articulated robot built for large-scale, high-force automation — handling heavy material transfer, large-part welding, and demanding assembly tasks that lighter robot series can’t manage.
Is the Heavy-Duty Series built for continuous, multi-shift operation?
Yes — it’s engineered as a production-critical asset for press lines, structural fabrication, and continuous multi-shift environments, not just occasional heavy lifting. The robot is built to run as a core part of your production line, not a supplementary tool brought in for specific tasks.
How is the Heavy-Duty Series different from the Universal Series?
Heavy-Duty handles significantly higher payloads (120–500kg vs. 12–120kg) with tighter repeatability (±0.06mm vs. ±0.07–0.08mm), making it the choice for heavy component handling, press lines, and large-part welding, while Universal Series covers general-purpose multi-tasking at lower payloads.
Can the Heavy-Duty Series be wall or ceiling mounted?
No — Heavy-Duty models are floor-mount only, unlike the Compact Series and Universal Series which support floor, wall, or ceiling installation. The higher payload and reach require the stability of a fixed floor mount
