Swingaway Mounting Adjustment
The following procedures may be used to adjust the existing
installation or for installing a new swingaway and/or stinger.
For the referenced details, refer to Figure 4-5.
1. With the swingaway base laying on the ground or
cribbing, use an adequate lifting device to place stinger
on the side of the base and install the one attach pin.
2. Raise the sheave end of stinger until the attach pin
installed in step 1 is loose. Install the ramp wear pad
(see Detail C) on the bottom of stinger and shim to
provide a clearance of 12 mm (0.5 in) between wear pad
and ramp on swingaway base.
3. Install the shock wear pad (see Detail C) on the
swingaway base bracket. Shim the wear pad to provide
a clearance of 3 mm (0.125 in) between shock wear pad
and ramp wear pad installed in step 2.
4. With stinger supported on the base ramp wear pad and
held tight against the shock wear pad, adjust stinger
latch hook (see Detail E) so that a 4 mm (0.156 in)
clearance is maintained between the hook and the latch
bar.
5. Remove Section 4 from the side of the swingaway base.
6. Disengage the boom stop and fully retract the boom.
7. Mount the swingaway base on the right side on the
boom base and install the pins attaching the swingaway
base to the boom nose.
8. Loosen the front and rear stowage bracket attaching
hardware.
9. Lift the sheave end of the swingaway base until the
attachment pins installed in step 7 are loose. Refer to
Detail D (rear stowage bracket) and adjust the lower
mount and the pin mount to maintain a loose condition of
the attachment pins. Tighten all rear stowage bracket
attaching hardware.
10. Refer to Detail A (front stowage bracket) and adjust the
main hanger, upper hanger, and lower support to
maintain a loose condition of the attachment pins.
11. Move the swingaway base away from the boom base
and mount stinger on the swingaway base using one
attach pin. Position swingaway base on stowage
brackets on side of boom.
12. Lift up on sheave end of stinger until attachment pin is
loose and stinger is 3 mm (0.125 in) from shock wear
pad at the ramp (see Detail C).
13. Refer to Detail B (stinger front stowage bracket) and
adjust the front mount and hanger to maintain the
attachment pin in a loose condition.
14. Refer to Detail D (rear stowage bracket) and adjust
stinger upper hanger and lower hanger to maintain the
attachment pin in a loose condition.
15. Some final adjustment of stinger latch may be required.
With the swingaway base and stinger in the final stowed
position on the stowage brackets, ensure there is
approximately a 3 mm (0.125 in) clearance between the
shock wear pad and the ramp wear pad on stinger (see
Detail C). In addition, stinger latch must be free
(approximately a 1.5 mm (0.059 in) clearance) between
the surfaces of the latch hook and the latch bar.
HOOK BLOCK
Description
A 55 metric ton (60 ton) hook block, a 45 metric ton (50 ton)
hook block, and a 8.3 metric ton (7.5 ton) headache ball are
available for the crane. The hook blocks utilize a one-piece
pivot block and the hook is equipped with a safety latch. Both
hook blocks are the quick reeve design. Grease fittings are
provided to ensure lubrication of all moving parts.
There are two types of headache balls available for this
crane. One is provided for use with the main hoist when
standard 6 x 37 WS wire rope is used. This headache ball
has a top swivel. A non-swivel type headache ball is
provided with the optional auxiliary hoist or when 18 x 19
wire rope is provided on the main hoist.
Maintenance
Periodic Maintenance
It is recommended that the hook block and/or headache ball
be inspected every 50 hours. A complete disassembly
inspection should be conducted every quarter or 500 hours
in the area of the hook, hex nut, and threaded areas for
corrosion and proper fit. After assembly of the hook, a liberal
coating of multipurpose grease should be applied to the nut
and threaded areas by brush or hand to prevent corrosion.
For hook blocks and other load handling devices not
manufactured by Manitowoc Cranes; follow the
manufacturer’s inspection and testing recommendations to
assure an adequate preventative maintenance program is
established.
CAUTION
Do not use a swivel type headache ball with 18 x 19 wire
rope.
