Introduction Buying a used industrial robot through an auction can provide manufacturers and automation companies with access to established robotic equipment while potentially reducing initial capital investment. However, the winning bid is only one part of a successful robot purchase. Before bidding on a used industrial robot, buyers must evaluate its technical specifications, physical condition, controller, maintenance background, integration requirements, and total cost of ownership.
Here are seven important factors every industrial robot buyer should evaluate before placing a bid. Overview Used industrial robots can deliver significant value when selected carefully and integrated correctly. Industrial auctions may feature robots previously used in automotive production, metal fabrication, material handling, welding, machine tending, and other manufacturing applications.
The key is to match the robot's actual capabilities with your intended application instead of making a decision based only on brand, payload, or auction price. 1. Confirm the Exact Robot Model The first step is to identify the complete robot model and configuration. Robots within the same product family can have different: Payload capacities Reach specifications Controller generations Mounting configurations Wrist capacities Application packages For example, two FANUC R-2000 series robots may look similar but offer different payload and reach capabilities.
Always verify the complete model designation before bidding. 2. Check Payload and Reach Requirements Payload and reach are among the most important factors when selecting an industrial robot. Payload Calculate the complete load the robot will carry, including: Workpiece Gripper Welding equipment Sensors Cables Additional end-of-arm tooling Selecting a robot that operates too close to its maximum capacity may not provide the ideal performance margin for every application.
Reach The robot must be capable of reaching every required point in the automation cell while maintaining appropriate orientation. A robot with insufficient reach can require major changes to the planned cell layout. 3. Evaluate the Robot's Condition Used robots may have operated for thousands of hours in demanding industrial environments. Buyers should evaluate available information about: Mechanical wear Gearbox condition Axis movement Cable condition Visible damage Corrosion Oil or grease leakage Unusual noise or vibration When operational testing is available, observe the robot moving through multiple axes and positions.
The physical appearance of a robot alone does not determine its mechanical condition. 4. Verify the Controller and Teach Pendant The robot controller is a critical part of the complete automation system. Confirm: Controller model Teach pendant availability Software version Installed options Communication capabilities Backup availability Compatibility with your planned application Older robots may still provide excellent mechanical performance, but integration requirements can vary significantly depending on the controller generation.
Understanding controller compatibility before bidding can prevent unexpected integration costs later. 5. Review Maintenance and Operating History Maintenance records can provide valuable insight into how a robot has been operated and maintained. Where available, review information regarding: Operating hours Preventive maintenance Gearbox servicing Lubrication history Battery replacements Motor replacements Previous repairs Collision history A well-maintained older robot may sometimes be a more suitable investment than a newer robot with an unclear service history.
If complete records are unavailable, buyers should account for the additional uncertainty when evaluating the robot. 6. Calculate the Complete Integration Cost One of the most common purchasing mistakes is focusing only on the auction price. The complete automation investment may also include: Robot transportation Loading and unloading Installation Programming End-of-arm tooling Safety fencing Safety sensors Electrical integration PLC communication Refurbishment Spare parts Commissioning For example, a robot purchased at an attractive auction price may still require significant investment before it becomes production-ready.
Calculate the estimated total project cost before setting your maximum bid. 7. Check Spare Parts and Technical Support Availability Long-term serviceability is an important consideration when purchasing any used industrial robot. Before bidding, investigate the availability of: Servo motors Gearboxes Cables Batteries Teach pendants Controller components Mechanical parts Technical support Widely deployed robot brands and models may provide advantages in terms of aftermarket support and spare parts availability.
