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.

Heavy-duty three-point grippers HGDT
Technical data
Opening and closing times [ms] at 6 bar
Without external gripper fingers With external gripper fingers
The indicated opening and closing
times [ms] have been measured at
room temperature at an operating
pressure of 6 bar with horizontally
mounted gripper without additional
gripper fingers. The grippers must be
throttled for greater loads [g]. Opening
and closing times must then be
adjusted accordingly.
