Characteristic load values at the gripper jaws
The indicated permissible forces and
torques apply to a single gripper jaw.
They include the lever arm,
additional applied loads due to the
workpiece or external gripper fingers
and acceleration forces occurring
during movement.
The zero coordinate line (gripper
finger point of rotation) must be
taken into consideration for the
calculation of torques.
