NOTE
In order to achieve the maximum lifting force, the clamping system
should be operated with an actuating pressure of 25 bar.
If the actuating pressure falls below this value, the clamping
system cannot be decoupled properly.

Unlocking
1 To unlock the clamping system, hydraulic pressure has to be
supplied (actuating pressure 25 bar).
2 The positively driven cylinder piston is moved upwards by
hydraulic pressure.
3 The return pins (item 5) connected by screws move into the
clamping slide bores (item 2), which move inwards and release
the clamping ring. At the same time, the optional lifting pins
(item 6) move upwards and lift the pallet.
The clamping pins can be delivered as separate accessories in
three versions (see chapter "Clamping rings SRA, SRB, SRC"
). The clamping rings are mounted on
customized pallets or devices.
4 The pallet can be removed.
Locking
1 Before inserting a pallet, the clamping system has to be
supplied with hydraulic pressure (actuating pressure 25 bar) so
that the clamping slides retract and the system is in unlocked
status.
2 The pallet can be inserted.
3 To lock the system, depressurize it.
4 The cylinder piston is guided downwards by spring force; first
the locking process takes place in a fast stroke, then the power
stroke is initiated. This leads to a very high pull down force.
When the turbo connection is used, the spring-actuated locking
procedure is actively supported with hydraulic pressure. If the
turbo connection is not used, it must be possible to ventilate
the relevant side of the piston.
5 The lifting pins lower and bring the pallet to the contact
surface.
