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).
