b. With the nuts (2) loosened enough to allow the trolley frame to move, slide the trolley motor side of

the hoist outward or inward to meet the desired flange width. Tighten nuts (2) with a torque wrench,
to 155 ft lbs (210 Nm). (See

Figure 3-6 and Figure 3-11.)

7) Installing the Drive Shaft

a. 2Ton – 10Ton Trolley Hoist

Install Snap Rings (S) on to Driveshaft (D) in position X3 or X4 depending on flange width (B)
of the runway beam and length (L) of drive shaft (D). Slide Drive Shaft through drive pinions
and install trolley motor. (See

Figures 3-8, and 3-9

. Also see

Tables 3-2 and 3-3.)

b. 15 Ton Trolley Hoist

Insert drive shaft (5) into the two drive pinions (6) from the counterweight side, then assemble
spacer tube (7) and adjusting ring (8). (See

Figure 3-11

).

Adjust drive shaft (5) so that on the hoist side of the shaft end projects between “min. 0in. (0mm)”
and “max. 4.72 in.(120mm)” beyond the drive pinion (6) and on the counterweight side the shaft end
projects between “min. 1.89 in. (48 mm)” and “max. 6.30in. (160 mm)” beyond the trolley frame (10).
(See

Figure 3-11

).

Lock adjusting ring (8) with the adjusting screw so that there is approximately "3 mm” space
between spacer tube (7) and the adjusting ring (8) when spacer tube (7) is against drive pinion (6).
After fitting travel drive, check drive shaft (5) for ease of movement. (See

Figure 3-11

).

8) Mounting the Trolley Hoist to the beam.

a. Install any additional devices, if any (power supply cords or pendants, for instance – see

Section

3.5

), onto the trolley hoist. If the trolley hoist is not secured to a pallet, place and secure it to one

making sure that the trolley hoist is completely stable.

b. Before attempting to install the trolley hoist, verify beam width and the “c” dimension (see

Figure 3-

6

). See

Table 3-1

for dimensions respective values.

Adjust flange width if necessary. (See

Section

3.4.1 Step 6

)

c. If the end of the runway beam is accessible, slide the trolley hoist onto the end of the runway

beam. Check clearance f/2 (

Figure 3-7 and Table 3-1

). Adjust if necessary. (

See Section

3.4.1 Step 6

).

If the end of the runway beam is not accessible, the trolley flange width will need to be opened
up to allow the Trolley Hoist to fit around the beam. (

See Section 3.4.1 Step 6

).
