The lever arm x [mm] must be taken
into consideration when determining
the actual spring force F

.
The formulae for calculating the
spring force are provided in the table

Determining the actual gripping forces F
Gr
for HGDT-...-A-G1 and HGDT-...-A-G2 as a function of the application, per gripper finger
The three-point grippers with
integrated spring type HGDT-...-G1
(opening gripping force retention) and
HGDT-...-G2 (closing gripping force
retention) can be used as:
– single-acting grippers
– grippers with supplementary
gripping force and
– grippers with gripping force
retention depending on the
requirements.
In order to calculate the available
gripping forces F
Gr
(per gripper finger),
the gripping force (F
Grip
) and spring
force (F
Stotal
) must be combined
accordingly.
Application forces per gripper finger

Gripping with pressure and spring
force:
