5.2.4. Moment and Force Limits
The 2-Finger Adaptive Gripper has limits for moment and force values. The maximum moment and force values are independent
of the grasp force the gripper applies on its payload. For payload calculation, refer to the Payload and force section.
Warning
Always operate within range.
Calculation of maximum moments and forces should include robot accelerations and safety factors.

Usage example with listed limits :
l
After picking its normal payload, the robot can use the 2-Finger 85 Gripper to apply up to 50 N of force in any direction. Apply-
ing more then 50 N can damage the gripper or result in payload loss.
l
A gripper can pick up a screwdriver and apply 3 Nm of torque to screw ( such moment would be applied in the Z axis).
