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.
