5 Product overview
5.1 Functional principle
Fig. 1 Functional principle
The product is a combined rotating and gripping module. Gripping occurs in the
closing direction of the gripper jaws (point of application on the outside).
The parallel gripper can be actuated electrically (EHMD­...­GE) or pneumatically
(EHMD­...­GP), depending on version.
In both versions, the parallel gripper can be continuously rotated by means of the
electric axis of rotation.
Gripping force backup
EHMD­...­GP: without gripping force backup. Backup for the gripping force can
only be ensured using additional measures (e.g. uninterruptible compressed air
supply).
EHMD­...­GE: with gripping force backup. If the power supply is interrupted, a min­
imum gripping force is ensured by the mechanical design. However, the maximum
gripping force cannot be maintained.
