3.4.1 Adjusting the trolley width – After assembling trolley per Section 3.5, check the adjustment as follows:
1) Refer to Figure 3-34.
2) Make sure both side plates are spread fully outward and measure dimension “A”. Compare dimension “A”
with the following values:
 For trolleys up through 5 Ton, “A” must be 3/32” to 5/32” greater than “B”.
 For trolleys 8 Ton to 20 Ton, “A” must be 3/16” to 1/4” greater than “B”.
3) If “A” does not fall within the specified range, move spacers from inner to outer or from outer to inner as
necessary to obtain the proper “A” dimension, irrespective of the numbers in Table 3-2.
4) After obtaining the proper adjustment, install the Shaft stopper Pin, insert the Split Pin into the Stopper Shaft
Pin, and securely bend both branches of the Split Pin.

For trolleys 8 Ton to 20 Ton, make sure to insert Shaft Stopper Pin into Hole
“A”. HOLE “B” IS FOR TROLLEY INSTALLATION ONLY.
5) Because two traversing units are combined in the 15 and 20 Ton trolley, ALWAYS adjust both units in the
same way.
