UNPACKING INFORMATION
When received, the hoist should be carefully inspected for
damage which may have occurred during shipment or han-
dling. Check the hoist frame for dents or cracks, the external
cords for damaged or cut insulation, the control station for
cut or damaged enclosure, and inspect the load chain for
nicks and gouges. If shipping damaged has occurred, refer
to the packing list envelope on the carton for claim proce-
dure.
Before installing the hoist, make sure that the power supply
to which it will be connected is the same as that shown on
the nameplate located on the side of the hoist.
NOTE: To assure long life and top performance, be sure to
follow the load chain lubricating instructions on page 15.
INSTALLING THE SUSPENSION
A. Single Reeved Units.
Remove the hook or lug suspension from its carton and the
two suspension screws. Place the suspension assembly into
the recess on top of the hoist so that the adapter body fol-
lows the contour of the hoist. Insert the suspension screws
through the holes in the adapter and hand thread these into
the self locking nuts enclosed in the hoist. The screws will
turn freely into the nuts until the last 1/4” (6.35mm) of travel,
during which the resistance of the nut locking collar will be
encountered. Securley tighten the screws to the recommed-
ed seating torque (see Table 2) using a 12 point socket
which fits the head of the screw.
B. Double Reeved Units:
Remove the hook or lug suspension from its carton and the
two suspension screws, dead end pin, washer and cotter
pin. It should be noted that a Double Reeved suspension
includes a dead end bolt and block for supporting the dead
end of the chain as shown if Figure 7.
Place the suspension assembly into the recess on top of the
hoist. The dead end block should project through the bottom
of the hoist with the pin hole and slot aligned to the under-
side of the hoist as shown in Figure 7. If these are not
aligned as shown, lift the head of the bolt and block assem-
bly and reseat the bolt head to obtain the proper alignment.
Do not change the position of the dead end block on the bolt
to attain this alignment.
Check the position of the pin hole in the dead end block to
make sure it has not been disturbed from its factory setting.
The distance from the top of the pin hole to the bottom of the
hoist should not exceed 1/4” (6.35 mm) for Models E, E-2, H
and H-2 and 7/16” for the Models R, R-2, RR and RR-2. If the
distance is not correct, adjust the position of the dead end
block to obtain the proper distance (see Page 48).

CHAIN CONTAINER
This accessory (see Figure 6) is used to hold slack chain
and it is supplied complete with mounting hardware and
instructions. The chain container is recommended for those
applications where the slack chain would interfere with the
load or drag on the floor as may be the case with double or
triple reeved units. Chain containers can be furnished for
units already in use.
