SELECTING YOUR KR012
Is the KR012 Right for Your Workstation?
Consider the KR012 when your workstation needs a wider tightening area, articulated movement and flexible mounting options. Select the configuration around your tool, fastening positions and position detection requirements.
A Wider Tightening Area
Reach options up to 2 m help accommodate fastening positions spread across a larger work area.
Tightening Within 100 Nm
Consider the KR012 for applications within 100 Nm, with the selected configuration matched to your tool and working reach.
Mounting to Suit Your Layout
Choose top, side or column mounting according to the available mounting space and workstation structure.
Optional Position Detection
Choose a version without sensors, or add XY or XYZ position detection when your process requires tool position feedback.
ARM STRUCTURE AND MOVEMENT
Long Reach with Articulated Movement
The KR012 combines a long-reach carbon fiber arm with an articulated structure. The manual illustrates 180-degree articulation, an adjustable balancer and an optional tool adapter, with position detection available in selected configurations.
Articulated Arm Structure
The illustrated 180-degree articulation allows the arm to fold and extend when moving between fastening positions.
Carbon Fiber Construction
Carbon fiber is used in the arm structure to support a lightweight, long-reach design.
Adjustable Balancer
The balancer provides adjustable tool support. Confirm its suitability for the weight of your tool and adapter.
Optional Tool Adapter
Select the adapter to match your tightening tool and mounting interface. The adapter is not included as standard.
CONFIGURATION OPTIONS
Choose Your KR012 Configuration
Configure the KR012 around your fastening positions, mounting space and position detection needs. Select the working reach, vertical travel and folding direction, then confirm the mounting and sensor options for your workstation.
Working Reach and Vertical Travel
Choose the horizontal radius and Z-axis travel to suit your fastening layout and required vertical movement.

Sensor Configuration
Output Options for Sensor-Equipped Configurations
Share your tool model, tool weight and fastening layout with KURAN to confirm a suitable configuration. Column height and carbon fiber pushrod length can be customized.
INSTALLATION OPTIONS
Three Mounting Options
The KR012 supports top, side and column mounting. Select the arrangement according to your workstation structure, fastening height and the space needed for arm movement.

Top Mounting
For workstations with a suitable overhead mounting point. Confirm the mounting height, arm movement clearance and tool reach.

Side Mounting
Use a suitable side mounting surface or bracket. Confirm the mounting interface and clearance around the arm’s folding path.

Column Mounting
Column height can be customized. Match the height to your fastening positions and required tool-side movement.
