H-855 High-Load 6-Axis Hexapod

Flexible Precision Positioning in the 500-kg Class

Holding force up to 5000 N
Travel ranges to ±160 mm, rotation ranges to ±60°
Absolute encoder
Actuator resolution to 5 nm
Flexible adaptation to requirements

High-load hexapod for loads to 500 kg. The device has a modular design, which allows a fast and flexible adaptation to a broad range of application requirements. The data table shows a couple of variants, making an estimation of potential extreme values possible.

Parallel-kinematic design for six degrees of freedom making it significantly more compact and stiff than serial-kinematic systems, higher dynamic range, no moved cables: Higher reliability, reduced friction.

Absolute encoders supply explicit position information that enables immediate determination of the position. This means that referencing is not required during switch-on, which increases efficiency and safety during operation.
