Welding Manipulators

Technial specifications
Parameter name | Description of Parameter | Typical range/example |
Carrying Capacity | The maximum static load (including the weight of tools/fixtures) that can be safely carried by the cantilever end should consider the influence of dynamic moment. | 50 kg ~ 2000 kg (common range of industrial grade) |
Main arm rotation speed | The horizontal rotation speed of the main column affects the working efficiency, and it is usually adjustable in steps or stepless speed regulation. | 0.5~5 rpm (low speed precision operation) 5~20 rpm (high-speed universal operation) |
Cantilever pitch velocity | Cantilever pitch adjustment speed (electric or hydraulic drive). | 0.1 ~ 2°/s (precision control) 2 ~ 10°/s (fast adjustment) |
Positioning Accuracy | Control accuracy of cantilever end position (uniaxial static). | ±0.05 mm ~ ±0.5 mm(High precision model) |
Repetitive positioning accuracy | The deviation of returning to the same position after multiple movements reflects the stability of the system. | ±0.1 mm ~ ±1.0 mm |
Multi-axis linkage accuracy | Comprehensive error (such as rotation+pitch) in multi-axis coordinated motion. | ±0.2 mm ~ ±2.0 mm(Depending on the control system) |
Use case
Technical specifications (such as load capacity, rotational speed, precision). Application scenarios (such as pipeline welding, wind turbine manufacturing).

Customer evaluation

We have purchased nearly 200 sets of roller frames for many years, and the stability of the large frame with a load of 30 tons exceeds expectations. Compared with other suppliers, you are really professional in welding technology and anti-deformation treatment, and there is no crack after three years of use in the harsh environment of the construction site.

As a partner for many years, the quality of your roller frame has been very stable, and both the load-bearing performance and durability meet our production needs. After-sales service is also in place, and problems can be solved quickly, which is trustworthy.

We have purchased your roller frame, positioner and column boom for a long time, and the equipment has a high degree of matching and the overall operation is stable. In particular, the positioning accuracy of the positioner and the bearing capacity of the roller frame fully meet our automatic welding needs, and cooperation is very worry-free.
