B. LUG SUSPENSIONS
The following instructions are provided to cover
installing the lug suspension after the hoist has been
reassembled following inspection and/or repair. On
hoists shipped from factory, the lug suspension is
installed prior to mounting the trolley.
1.
2 Ton Single Reeved Units.
Slide the suspension
adapter into the cavity on top of hoist and secure it
using the suspension adapter screw. Tighten the
screw to a seating torque of 16 pound feet (22 NM).
2.
3 And 5 Ton Double Reeved And 6 And 7½
Ton Triple Reeved Units.
Slide the suspension
adapter into cavity on top of hoist. Install the dead
end bolt and thread it by hand to engage the dead
end block (3 and 5 ton double reeved units) or idler
sheave hanger ( 6 and 7 1/2 ton triple reeved
units). Then tighten the dead end bolt to a seating
torque of 120 pound feet (160 NM).

MOUNTING TROLLEY ON HOIST
The following instructions are provided to cover mount-
ing plain, geared and motor driven trolleys after the hoist
has been reassembled following inspection and/or repair.
On units shipped from factory, these trolleys are mounted
on the hoists.
1. Measure the actual width of the beam flange on
which the trolley is to operate. To determine proper
trolley side frame spacing to assure that adequate
wheel clearance is provided, the distance between the
beam flange and the inside face of the trackwheel
flange (approximately 1/8 to 3/16 inch on straight
runway beams, 3/16 to 1/4 inch on curved beams for
2 ton units. See Figure 2 -page 7 and 1/4 inch for
straight runway beams, 3/8 inch on curved beams for
3 thru 7 1/2 ton units. See Figure 1 - page 7).
2. Use Table 2 (page 7) to determine proper spacing for 2
ton plain and geared units. On 2 ton motor driven
trolleys and, 3 thru 7 1/2 ton capacity units, proper
spacing is obtained by varying the number of spacer
washers (furnished with trolley) that are installed on
the suspension pins.
3. For 2 ton units, assemble a slotted nut to one
end of each suspension bolt and secure it using a
cotter pin. Spread legs of cotter pin to keep it in
place. Using Table 2 (page 7) as a reference for washer
spacing, assemble side frames and bolts and
washers together as shown below. Do not install
remaining cotter pins at this time. These are to
be installed after the trolley is mounted on the
beam.
For 3 thru 7½ ton units, temporarily assemble trolley to
hoist using 3 or 4 washers at each end of suspension pins,
between side plates and suspension lug. Tighten pin nuts
for accurate check of spacing. Measure the distance
between the inside faces of the trackwheel flanges and
compare to the dimension required. Remove trolley side
plates and add or remove an equal number of inside spac-
er washers as required to obtain proper distance between
wheels. When spacing is correct, install all remaining spac-
er washers on the outside ends of each suspension pin
and secure the pins with lockwashers and hex nut (See
Note Below). The nuts should not be completely tight-
ened until after hoist and trolley are mounted onto
beam.
NOTE: It is very important that all spacer washers
that come with the trolley be used. Install
remaining spacer washers equally on out
side ends of each suspension pin.
!
WARNING
Using other than factory supplied suspension adapter
screw or dead end bolt to attach suspension adapter
to hoist may cause the screw or bolt to break and
allow the hoist and load to fall.
TO AVOID INJURY:
Use only the factory supplied suspension adapter
screw or dead end bolt and tighten these to the seat-
ing torque specified above.
