3.3 Mounting Location
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”.
3.3.3

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 Figure 3-4.
Figure 3-4 Trolley Hoist Clearances

18
3.3.5

See Section 6.8for outdoor installation considerations.
3.4 Assembly, Adjustments and Mounting

When installing the trolley hoist on a beam, ALWAYS raise the hoist into position with the
trolley assembled together and securely attached to a pallet/skid. Raise the trolley hoist with a forklift, lifting
platform, or other similar means. NEVER use slings to raise and install the trolley hoist onto the beam.Using a
forklift or another suitable means, position the pallet/skid so that the horizontal axis of the beam is parallel to the
horizontal axis of the trolley hoist as shown in Figure 3-6.
Figure 3-6 Trolley Secured to Pallet/skid for Installation
Note: Unless specified when ordered, the RY trolley hoist is factory set to accommodate a 4.92 to 13.78 inch
beam flange. A wider flange range for beams with flange widths 13.79 to 19.68 inches is available.
The RY is equipped with the maximum counterweight necessary for the standard and optional flange range,
4.92 to 19.68 inch, for each hoist capacity.
3.4.1 RY Trolley Hoist Installation
1) Make sure the mounting location complies with Section 3.3.
2) Install any additional devices, if any (power supply cords or pendants, for instance – see Section 3.7)
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 as shown in Figure 3-6.
3)

Only move/adjust the Trolley Frame “adjustment side” (side with trolley motor) of
the trolley. The “adjustment side” is easily identifiable as the trolley motor is bolted to it. Never loosen
the Adjusting Bolt Nuts on the “fixed side” or attempt to move the “fixed side” of theTrolley Frame. See
Figure 3-7 for Trolley Frame identification. Loosen the Socket Bolt attached to the lower side of the
boss on the Trolley Frame “adjustment side” (trolley motor) side as shown in Figure 3-7 and Figure 3-
8.
4) Before attempting to install the trolley hoist, verify beam width, “B” and the “A” dimension as shown in
Figure 3-10. Adjust flange width if necessary.

19
5) To adjust the flange width of the trolley, loosen the Socket Bolt located on the underside of the
“adjustment side” of the Trolley Frame on each as shown in Figure 3-7 and Figure 3-8.
To widen the flange width: Loosen the adjusting nut on the outer side of the trolley frame (adjustment
side) and tighten the nut on the inner side of the trolley frame (adjustment side) shown in Figures 3-8.
This must be performed uniformly on both Adjusting Bolt locations on each end of the hoist as shown in
Figures 3-7. Confirm dimension “A” as referenced in Figure 3-10.
To narrow the flange width: Loosen the adjusting nut on the inner side of the trolley frame (adjustment
side) and tighten the nut on the outer side of the trolley frame (adjustment side) shown in Figures 3-8.
This must be performed uniformly on both Adjusting Bolt locations on each end of the hoist as shown in
Figures 3-7. Confirm dimension “A” as referenced in Figure 3-10.
Figure 3-7 Adjusting distance between frames to accommodate beam
6) If the end of the runway beam is accessible, slide the trolley hoist onto the end of the runway
beam. Check the Trolley Wheel to Guide Roller clearance, “t”. “t” = 5/64 inch as shown in Figure
3-10. Adjust the Trolley Frame as necessary to meet the Trolley Wheel to Guide Roller
clearance, “t”. (See Section 3.4.1 Step 5 for proper adjustment procedure).
Figure 3-8 Loosen the Adjusting Bolt Nuts and Socket Bolts

20
7) 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 5 for proper
procedure to widen flange width.)
8) Once the hoist is in position with the beam flange wheel running surface, the trolley flange can be made
narrowed to accommodate the respective beam flange width. Confirm dimension “t” = 5/64 inch as
shown in Figure 3-10. (See Section 3.4.1 Step 5 for proper procedure to widen flange width.
Figures 3-8, 3-9 and 3-10)
9) After adjusting the Trolley Frames for the correct beam flange width, tighten the Socket Bolt that was
loosened in step 3) and tighten the Adjusting Bolt Nut.
