RAM AND UPPER BLADE COUNTERBALANCES
To assist the flywheel in maintaining maximum energy and to keep the ram tight against its slide bearings, each
shear is provided with Ram and Upper Blade Counterbalances.
The counterbalances systems provided on the 0200, 0300, and 0400 series shears are of the coil spring type (Figure
18.) Very little attention is
required of
these counterbalances; however, if
any looseness is
noted between the ram and the
slide bearings, tighten nuts "A" (Figure 18) a few turns on each counterbalance. This adjustment should only be made with
the ram jogged to the bottom of the stroke.
The counterbalance system on the 0600, 0800,
and 1000 series shears consists of two air cylinders
equipment. the only adjustment necessary is the initial
pressure adjustment. This pressure varies with the
length of the machine and type of back gauge and
Lubrication of the air cylinder should be maintained
as set forth In the lubricating instructions on page 6.
