(Typical 3 and 5 Ton)
(3)Pass free end of rope thru bottom opening of hoist between floating limit rod and motor, and insert rope in anchor fitting at hoist frame. Be certain power is off before attempting to place rope in anchor fitting. With end fitting properly seated in anchor, replace bolt and lockwasher in end of socket. Two loops have now been formed for bottom block sheaves.

Figure 5-14. Hoist Reeving — Four Part Single.
(4)Place one sheave in each loop. Install one sheave with cable in bottom block, partially insert sheave pin to hold sheave in place. NOTE: Some blocks have spacer washers between sheaves. Be certain that washers are installed between sheaves, when shown on parts illustration. Install second sheave with cable into bottom block. Slide sheave pin through sheave. Replace key plates and bolts securing sheave pin.
(5)Replace sheave guard.
(6)Lubricate cable per paragraph 4-3. f. Reeving — 6 par t single.
See Figure 5-15 for diagram.
See Figure 9-13 for block parts.
With new rope installed on the drum as described in paragraph 5-9c single reeved above, proceed with rereeving following steps below:
(1)Grasp cable at a point one-third (approx. 14’0") the distance hanging below the rope drum and form a loop. Place one upper sheave in this loop. Slide upper sheave with cable into sheave pocket; partially insert sheave pin to hold sheave in place.
(2)Repeat (1) above and install second upper sheave with rope. Insert sheave pin and install key plates and bolts to secure sheave pin.

(3)Pass free end of rope thru bottom opening of hoist between floating limit rod and motor and insert in rope anchor fitting at hoist frame. Be certain power is off before attempting to place rope in anchor fitting. With end fitting properly seated in anchor, replace bolt and lockwasher in end of socket. Three loops have now been formed for bottom block sheaves.
(4)Place sheave in each loop. Install one sheave with cable in bottom block; partially insert sheave pin to hold sheave in place. NOTE: Be certain that washers are installed between sheaves, as shown on parts illustration.
(5)Repeat step 4 for remaining bottom block sheaves. Install sheave pin through sheaves. Replace key plates and bolts securing sheave pin.
(6)Replace sheave guard.
(7)Lubricate cable per paragraph 4-3. g. Reeving — 2 par t double.
See Figure 5-17 for diagram.
See Figure 9-12 for block parts.
With new rope installed on the drum as described in paragraph 5-9c double reeved above, proceed with rereeving following steps below:
(1)Form loops in the two ropes coming from rope drum. Place these loops into bottom block pockets and slide pipe or rod through sheave pin holes. Note position of ropes passing limit stop bar.
(2)Partially insert upper block sheave pin in opening and install one spacer washer. Raise remaining rope up to hoist, form a loop and place upper sheave in this loop.
