5. With  the  trolley  mounted  on  the  beam,  attach the hoist by inserting the suspension lug into the trolley load  bracket  and  inserting  the  suspension  pin  through the load bracket and suspension lug as shown in Figure 7. 6. Thread    the    socket    head    cap    screw    and lockwasher into load bracket and tighten securely. 7. Now,   return   to   page   4   "Power   Supply   and Electrical Connections" and complete the hoist installation procedure. 8. Then   with   a   capacity   load   on   hoist,   operate trolley   over   the   entire   length   of   runway   or   monorail system to be sure that the adjustment and operation is satisfactory.  On systems with curves, the edges of the rail   at   the   curved   sections   should   be   kept   lightly lubricated with grease. Motor Driven Trolley This  trolley  is  shipped  separately  and  must  be assembled and wired to the hoist by the user.  Refer to the instruction manual packed with the unit. Enclosed Collectors and Wiring On  low  headroom  trolley,  collectors  are  to  be installed   on   each   side   of   trolley.      On   motor   driven trolley,  all  collectors  are  to  be  installed  on  one  side  of trolley. Installation Procedure- 1. Make sure power supply to conductor system is shut off. 2. Refer   to   Figure   9   to   determine   the   proper mounting   position   for   the   collector   bars   and brackets. 3. Attach the brackets by inserting the screws into tapped holes in the side frames.  Tighten screws securely. FIGURE 8. 4. Place an insulator on each collector bar. 5. Position  the  bars  in  the  brackets  and  lock  with set  screws.    Mount  collectors  on  bar  to  match conductor system. 6. Again  refer  to  Figure  9  position  the  collectors on.  the bars as shown. 7. Measure  the  length  of  power  cable  needed  t reach     the     farthest     collector.          Allow     for connecting the wire to the collector shunt screw and cut off the cable. 8. Strip  back  the  insulation  as  required  and  cutoff Green wire if no ground conductor is installed. 9. Attach wires to collector's shunt screw ( Fig.  8). 10. Check    installation    to    make    sure    that    the collectors  make  proper  contact  throughout  the entire length of trolley travel. 11. Energize  conductor  system.    On  three  phase units check for proper direction of hook travel by following instructions on page 5. ALTERNATE METHODS OF WIRING A flexible conductor cable can be used to supply power   to   a   trolley   mounted   hoist.      The   length   of conductor   should   be   adequate   for   the   full   travel   of trolley.  A long conductor will usually require a clamp or strain relief (available from factory) fitting at the hoist to prevent  kinking  where  the  conductor  enters  hoist.    To keep the slack conductor awe from the hoist and load, a messenger  wire  system,  a  counterweighted  pulley  or  a spring  loaded  cord  reel  (available  from  factory)  can  be used. 8
