The
trolley
side
plates
must
be
spaced
so
the
trolley
wheels
will
properly
engage
the
beam
on
which
the
trolley
will
be
operated.
Adjustment
for
various
beam
sizes
is
accomplished
by
arrangement
of
the
spacer
washers
on
the
shaft
which
connects
the
trolley
side
plates.
The
hoist
can
be
suspended
from
the
trolley
by
using
trolley
adapter
or
by
attaching
the
upper
hook
directly
to
shaft
Use
of
the
trolley
adapter
is
recommended.
Trolley
parts
can
be
found
in
manual

for
the
TIR/RT
trolley

The
distance
between
the
outside
edges
of
the
trolley
wheels
should
be
approximately
1/2
inch
greater
than
the
width
of
the
beam
flange.
The
number
of
spacer
washers
used
to
space
side
plates
out
must
be
the
same
on
each
side
of
the
shaft
(or
trolley
adapter)
and
the
remaining
spacers
must
be
equally
distributed
on
the
shaft
outside
the
trolley
side
plates
at
each
side
between
the
side
plates
and
lock
nuts,
.
When
installing
the
trolley
on
the
beam,
be
certain
side
plates
are
vertical.
Assemble
trolley
adapter
to
hoist
housing.
Determine
the
number
of
spacer
washers
needed
to
properly
space
side
plates
for
beam
to
be
used,
and
assemble
shaft
to
trolley
adapter.
Assemble
spacer
washers,
side
plate,
spacer
washers
and
nut

side
plate,
spacer
washers
and
nut
to

Tighten
nuts
securely.
The
lock
nuts
must
properly
engage
shaft
extending
all
the
way
through
the
nut.
The
trolley
wheels
should
be
positioned
as
close
as
possible
to
the
edge
of
the
beam
flange.
Operate
the
trolley
over
the
entire
length
of
the
beam
track
and
observe
operation.
If
it
appears
the
trolley
side
plates
can
be
moved
closer
together
and
freedom
of
movement
maintained,
remove
an
equal
number
of
spacer
washers
from
between
the
side
plates
and
trolley
adapter
at
each
side
and
assemble
these
spacers
to
the
outside
of
the
side
plates
between
the
side
plate
and
lock
nuts.
The
beam
on
which
the
trolley
is
to
be
used
must
safely
support
the
combined
weight
of
the
hoist,
trolley,
and
capacity
load.
Minimum
