Description of the product
Function
The hydraulic swing clamp is a pull-type cylinder where a part
of the total stroke is used to swing the piston.
The piston rod locking is made by a separately-controlled dou-
ble-acting wedge-shaped piston.
Clamping:
1. Swinging and clamping
2. Locking
Unclamping:
1. Release locking
2. Unclamping and swinging back
Self-locking
The wedge-shaped piston is designed as a self-locking piston
so that the swing clamp can be depressurised after clamping.
The previously generated clamping force will be maintained.
Conditions: Before depressurising, the locking pressure must
be available at least for 3 seconds.
Special features
•
The patented piston rod locking is made by friction locking
by a separately-controllable double-acting wedge-shaped
piston with self-locking. In the case of a pressure drop or
complete pressure reduction, the clamping force will be
maintained.

Omission of the overload protection device
2
In the case of a slight collision with the clamping arm during
loading and unloading of the fixture, the angular position of
2
the clamping arm will be maintained. Less critical are the
weight of the clamping arm or an increased swing speed.

Reinforced swing mechanism
The reinforced swing mechanism endures a collision of the

clamping arm with the workpiece during clamping up to a
pressure of 100 bar.
