Enerpac RC-Series Plunger clevis attachments - Manual (Page 2)

3.0 OPERATION
1. Base clevis attachments are
for use on ENERPAC RC
single-acting cylinders.
Cylinder capacities are 5
through 30 ton (see Table
1).
2. The clevis mounts to the
cylinder plunger (see Fig. 1)
and provides a method of
attaching cylinders to
custom fixtures or set-ups
where the cylinder is used
for pushing only. CAUTION:
The clevis attachment is
not designed as a pulling device. When used for pushing and
installed properly (see Fig. 2) the clevis will withstand full-rated
cylinder capacity.
4.0 INSTALLATION
1. Thread the clevis attachment into the cylinder plunger until the clevis
is seated against the top of the plunger. The clevis must be fully
threaded into the plunger to provide full capacity and avoid damage
to clevis and plunger threads.
2. Install the clevis and cylinder to fixtures using cold drawn steel pins
through the clevis and fixture. Refer to Table 1 for correct pin sizes
and Fig. 2 for recommended mounting condition. View "A" is correct,
providing a stable condition. Views "B" and "C" do not provide a
stable mounting condition.
