The hoist may be operated in any convenient position and the
handle may be operated on either side of chain as shown by the
arrows X and Y (above) on the drawings.
To put the hoist in free-wheeling, turn the shift key finger to
the "Dn" (down) position and hold the release key in the
direction of the arrow. Pull the chain in the "Up" direction
approximately 2 links then pull on the hook side of the chain
to get sufficient slack to hook onto the load. To take up slack,
simply pull on the free end of the chain, the hoist will ratchet
even though the release key is not depressed.
TO LIFT A LOAD:
Turn the shift key finger to "Up" and operate the handle. The
handle may be operated on either side of chain as shown by the
arrows (X) and (Y) on the drawing.
TO LOWER A LOAD:
Turn the shift key finger to "Dn" (down) and operate the
handle. The handle may be operated on either side of chain as
shown by the arrows (X) and (Y) on the drawing.
TO SHIFT HANDLE:
To change position of handle from side marked X to side
marked Y press release key in direction of arrow.
DISASSEMBLY INSTRUCTIONS FOR PERIODIC
INSPECTION AND REPAIR OR REPLACEMENT OF PARTS
The Chance Hoist is designed to provide long and rugged
service. Observing the suggestions listed below will increase
the service life of the hoist:
1.
The hoist should be inspected, cleaned and re-lubricated
periodically depending on usage conditions.
2.
When lowering a light or "bouncing" load do not flip or
otherwise cause the handle to become self-ratcheting.
Allowing the handle to self-ratchet causes undue wear on
the stop areas and reduces the wear life of the hoist. In
addition, the free-ratcheting handle could strike the op-
erator.
3.
When operating the handle it is not necessary to "slam"
the handle past the ratcheting position. Constant impact
will increase wear of the hoist mechanism.
When placing the hoist in operating position, care must
be taken to make sure that the load hook and the
housing hook of the hoist are on the same centerline. If
the hoist is restricted from adjusting itself to form a
straight line with the direction of loading, damage to the
hoist could occur.
TO POSITION HOIST FOR USE:
In order to best visualize these instructions, study and refer
to the exploded view of the hoist.
1.
Remove snap ring (056011) from shaft (019555).
2.
Push "release key" (P309-0346) in the indented area of
the handle in the direction marked "release" to disen-
gage the working pawl from the unloader plate and lift
handle assembly off the shaft. This will expose the
mechanism.
3.
The working pawl may be removed by first removing
screw (56013) and washer (56014) from the post sup-
porting the pawl. Torsion spring (56010) can be re-
moved, after the dog, if needed.
4.
When reassembling working pawl and spring (56010),
place the short leg of the spring to the pin on the pawl,
on the side facing handle (P309-0816), and the long leg
of the spring against the handle housing (P309-0816).
5.
If necessary to replace the pawl post (19486) or release
key (P309-0346) press the pawl post out of handle with
a careful and steady force. In replacing the new pawl
post (19486), be certain it is pressed in straight, using
an even pressure, and that release key (P309-0346) is in
position before pressing post into handle.
6.
The holding pawl can be removed by unhooking the two
extension springs from the unloader plate and from
screw (56163) in the housing. Remove snap ring (56011)
and slide unloader plate off shaft (019555) after which
pawl can be lifted off post (56016).
7.
After unloader plate has been removed, ratchet (19556)
may be slipped off the shaft. Then woodruff key (56507)
may be removed. The shaft (019555) may be slipped out
of bearing bore.
8.
In replacing the holding pawl, make sure the pin which
is permanently secured to the pawl is faced to the
outside, so that it projects through the unloader plate,
when it is replaced on the shaft.
9.
To remove the ratchet gear and chain socket, disconnect
chain end and pull out of housing (on reassembly, insure
welded side of chain is away from chain socket). Then by
removing interlocking snap ring (56011), the chain
socket and gear (019549) will slide out in one piece.
10.
Hook (P309-0389) may be removed from the housing
after pressing roll pin (P001-1460) from the nut (P001-
0757) and unscrewing hook from nut.
11.
The shift key (P309-0043) can be removed by backing out
the drive-lock pin (59036) holding the shift key finger
(19296) to the shift key.
12.
The bearings (058613, 058614) can be removed and
replaced in the accepted manner of pressing them out
and pressing the new ones in.
To remove Interlocking Snap
Ring, pry one end apart using
screwdriver. Parts may fly
away when Ring unsnaps.
To reinstall, hook one end and
close with pliers.
To reassemble, follow these instructions in the reverse man-
ner replacing parts in the same position as noted when
removed.
It is important that the hoist be inspected, cleaned, and
relubricated periodically depending on working conditions.
