Enerpac LCA-Series - Manual (Page 3)

3.2 Arm Attachment
Place the clamp arm over the plunger end, lining up
the pivot pin holes. The clamp arm should extend
between the two links previously installed. Insert the
supplied short pivot pin through the arm and the
plunger, securing the parts together with the supplied
E-clips (Figure 4).
Figure 4
Then, insert the second long pivot pin through the
top holes on the links and through the top hole on the
clamp arm, securing it with the last two supplied
E-clips (Figure 5).

3.3 Mountings
Cylinder Mounting
Enerpac link clamps can be mounted using either the
top flange and the supplied mounting bolts; or
through the use of the body thread on the cylinder
and a jam nut.
Note: mounting the cylinders using the body threads
prevents plumbing the cylinders through the manifold
ports on the underside of the flange. The only way to
utilize this plumbing method is to flange mount the
cylinder.
Flange Mounting
Flange mounting requires the machining of a thru-
hole in the fixture plate or mounting block and
mounting threads for the four bolts (Figure 6).
See Table 1 below.
Align the cylinder in the proper orientation to provide
clamping force to the part and then install the
mounting bolts and tighten per the chart below.
Failure to tighten the mounting bolts properly can
result in damage to the cylinder and premature failure
of the clamp.
Threaded Body Mounting
Mounting the cylinder using the body threads
requires a clearance hole machined in the fixture
plate and the installation of a jam nut to secure the
cylinder in
place. The
c l e a r a n c e
hole should
be sized
according to
t
h e
dimensions
in Figure 6.
