All Trolleys For  all  trolley  supported  hoists,  rail  stops  must be  installed.    These  stops  must  not  be  positioned  to exert  impact  force  on  the  hoist  but  should  contact  the end of the trolley side frames. Low Headroom Trolley This  trolley  is  packed  separately  and  must  be properly adjusted by the user to fit the runway beam as follows: 1. Arrange  the  side  frames,  load  bracket,  spacer washers   and   nuts   on   the   suspension   bolts according  to  Figure  6  and  Chart  1.    (Warning, special  trolleys  shown  in  chart  require  special suspension bolts).  Do not assemble cotter pins to the bolts. FIGURE 6.  LOW HEADROOM LODESTAR TROLLEY. 2. The  number  of  spacers  as  given  in  Chart  I  is nominally correct, however, due to the variation in size encountered on structural steel sections, it  will  be  necessary  in  some  cases  to  vary  the number used.  Therefore, the distance between the  trolley  trackwheel   flanges,   and   the   beam flange  width  should  be  measured  to  determine the exact distribution of the spacer washers. The distance  between  trackwheel  flanges  should  be 1/8"  to  /';"  greater  than  the  width  of  the  beam flange  for  straight  runway  beams  and  3/16  to 1/4"  if  runway  system  includes  sharp  curves. The  number  of  spacer  washers  between  side frames and load bracket should be the same or differ only by one spacer to keep the hoist hook centered under the runway beam. 3. Install  the  trolley  on  beam  by  sliding  one  side frame out far enough to allow the trackwheels to clear the beam flange. WARNING: Deviation from CM washer recommendations   can   cause   trolley   to   fall   from   the beam.  The  trolley  should  be  inspected  periodically  to assure its continued operation. CHART I -TROLLEY SIDE FRAME SPACING. 4. Draw  the  side  frames  together  and  assemble cotter pins. FIGURE 7. ATTACHING HOIST TO TROLLEY. 7
