Product overview
5.1
Function
Alternating pressurisation of the supply ports moves two pistons in the gripper
(double-acting).
The piston movement is transmitted mechanically to the gripper jaws.
The gripper jaws move towards one another (closing) or apart (opening). Gripper
fingers are fastened to the gripper jaws.
The payload can be gripped in 2 ways:
–
on the external contour (external gripping) when closing
–
on the internal contour (internal gripping) when opening
The gripper has integrated fixed flow restrictors. If the maximum gripper finger
weights and lengths are in compliance, external flow control is not required.
