3.3.1

Prior to mounting the RY trolley hoist ensure that the wire rope has not loosened
on the wire rope drum. Due to vibration or other impacts during transportation of the product, the
wire rope wound on the Rope Drum may be loosened. Check for “slack” in the wire rope on the
drum. Remove all “slack” from the wire rope on the drum.
1)
Pull the load side of the Wire Rope wound on the Rope Drum to remove slack and confirm
that the Wire Rope is settled in the groove of the Rope Drum.
2)
If slack still remains, move the loosened part of the Wire Rope toward the Rope Guide side
so as to gradually remove the slack. When the slack reaches the Rope Guide, pull the Wire
Rope to completely remove the slack.
3)
If slack cannot be removed by the steps above, detach the Rope Guide and remove the slack
and entanglement of the Wire Rope.
3.3.2 For the procedure of installation and removal of the Rope Guide, see Section 6.6.6 “Wire Rope
Installation/Rope Guide Installation ” .

Prior to mounting the RY trolley hoist ensure that both the trolley beam lower
flange rating meets or exceeds the trolley hoist reaction forces listed in Table 2-8 and the beam
supporting structure is adequate to support the trolley hoist and its load. If necessary consult a
professional that is qualified to evaluate the adequacy of the suspension location and its supporting
structure.
3.3.4 Ensure that there is adequate vertical and horizontal clearance along the entire range of the trolley
hoist’s motion as shown in
