3.0 Pre-operational Pr ocedur es
3.1 General Information
3.1.1 When the RY trolley hoist is incorporated into lifting systems utilizing other equipment, follow and
complete all pre-operational procedures and instructions provided with the equipment. Special
wiring considerations must also be taken to complete the integration of the RY trolley hoist into
the system.
3.1.2 The RY hoist is delivered pre-assembled on a plastic-covered pallet/skid as shown in Figure 3-1.
During shipment and storage prior to installation, the trolley hoist should be kept between –4° and
+104°F (-20° and +40°C) and the relative humidity must not exceed 90%. The standard packaging is
not watertight and rainproof.
3.1.3 The RY trolley hoist is shipped with the wire rope installed and reeved from the wire rope drum through
the return sheaves and hook block to the dead end, reference Section 6.6.
3.1.4 The RY trolley hoist is shipped pre-lubricated with the correct amount of lubricant in the gear box(s).
Follow the lubrication requirements in Section 6.2 after the trolley hoist is placed into service.
3.2 Handling
3.2.1 Transportation – When moving the trolley hoist prior to installation, do NOT remove the trolley hoist
from the pallet. Always move trolley hoist utilizing a fork lift, pallet jack or hoist/crane system. Do NOT
stack or place anything on top of the trolley hoist or crate. Avoid swinging and unbalanced conditions.
3.2.2 Lift points – When a pallet is not practical, use of the RY lifting points or the trolley frame is acceptable.
The RY trolley hoist is equipped with threaded lifting lugs in the horizontal tubes (see
Figure 3-3
Figure 3-1 Packaged as delivered
Figure 3-2 and
). While lifting do NOT support the trolley hoist any other way.

3.3 Mounting Location
Figure 3-3 Sling Lifting Method
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
17
3.3.5
See Section 6.8 for 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.
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.
Using a
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)
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.
Only move/adjust the Trolley Frame “adjustment side” (side with trolley motor) of
18
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

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.

3.5 Block Operated Limi t Switch (BLS) Adjustment
The BLS must be adjusted to where the Hoist and the Hook Block do not interfere with each other. The BLS
operates when the Upper/Lower Limit Switch does not function due to failure, improper setting, or abnormal
operation. The load can be lowered after the BLS has been activated.
1) Because the BLS is attached to the Suspension Shaft, its position must be adjusted after installing the hoist
on the beam.
2) Adjust the position of the BLS to the center of the beam flange or the position where the center of the Hook
Block and the BLS can make contact, then set the angle of the lever to the position where the “notch” in the
BLS frame is horizontal (parallel to the beam flange) as shown in Figure 3-11.
3) Tighten the nuts to a torque setting of 20.7 lbf-ft (28 N• m).

RY lifting and traversing motions are variable frequency drive (VFD) controlled.
Before proceeding, ensure that the electrical supply for the hoist or trolley has
been de-energized (disconnected). Lock out and tag out in accordance with ANSI Z244.1 “Personnel
Protection -Lockout/Tagout of Energy Sources”.
To avoid a shock hazard, DO NOT perform ANY mechanical or electrical
maintenance on the trolley or hoist within 5 minutes of de-energizing (disconnecting) the trolley or
hoist. This time allows the internal VFD capacitor to safely discharge.
Do NOT remove power to the trolley hoist during operation.
All RY trolley hoists are dual speed hoists and trolleys that are equipped with
VFD’s. The VFD’s are used to control the high and lo w lift i ng and traversing speeds. The speeds
come preset from the factory (See Table 3-5). Speed (frequency) can be customized. Refer to
Section 3.8.13 for hoist specific speed ranges and instructions and Section 3.11.5 for trolley
traversing speed ranges and instructions.
3.6.8 Installing Power Supply Cord
1) Refer to Figure 3-12 and the wiring diagram provided with the Hoist.
2) Remove Control Cover.
3) Multiple cable fittings/clamps are available for use on both sides of the Control Panel for the Power
Supply Cord. Loosen the selected cable fitting/clamp and insert the Power Supply Cable. Pull
through enough cable to reach the power supply terminal and securely tighten the cable fitting as
shown in Figure 3-12.
4) Pull the Power Cable to check that it does not move in the cable fitting/clamp.
5) Connect the 3 phase power leads (L1, L2 and L3) and the ground lead of the Power Supply Cable
to the power supply terminals, Red, White, Black and Green/Yellow (ground). Make sure the
terminals are securely tightened and each lead is completely isolated as shown in Figure 3-12.
6) Connection to Electrical Power Source - The Red, White and Black wires of the Power
Supply Cable should be connected to an Electric Power Disconnect Switch or Circuit
Breaker.
7) Fuse/Breaker Capacity -The hoist's power supply should be equipped with current overload
protection such as fuses, which should be selected for 110% to 120% of total listed full load
amperage, and should be dual element time-delay fuses. Refer to the motor nameplate for
the full load amperage draw.
8)
electrical shock hazard when touching any part of the hoist or trolley. In the Power Supply
Grounding - An improper or insufficient ground connection creates an
23
Cable the ground wire will be either Green with Yellow stripe or solid Green. It should always
be connected to a suitable ground connection. Do not paint the trolley wheel running
surfaces of the beam as this can affect grounding.
9) Replace the Control Cover. Be careful to not damage the seal or sealing surfaces and make sure
to securely tighten all fasteners or latches.
3.7 Pendant Installation
If Trolley hoist was supplied without a Pendant/Control Cable. The installer must use
a UL List Pendant along with a UL Listed Pendant Cord/Control Cable Type SO, SOO, SOOW, ST, STO,
STOO or of a type at least equally servicable for the particular application and suitable for use with a
Pendant rated 60ºC minumum, 600V, 18 ga. minimum. Always consult with a qualified person when
appropriate Pendant Cable sizing is in question.
In outdoor, damp or applications subject to moisture, a NEMA 4 rated pendant shall
be used.
1) Refer to Figure 3-13, Figure 3-14 and the hoist wiring diagram for pendant connections.
2) Remove Control Cover.
3) Loosen the cable fitting located on the lower side of the electrical enclosure and insert the Pendant
Cable. Pull through enough cable to reach the terminals then securely tighten the cable fitting.
4) Attach a strain relief cable or chain between the pendant and hoist. The cable should attach to the
small plate located at the bottom of the electrical enclosure under the gear box.
5) Access to terminal strip: The terminal block/strip is mounted to the left of the VFD in the control box, as
shown in Figure 3-13.
Figure 3-12 Power Supply Connection Points
6) Connect the individual pendant leads to the correct terminals as shown in Figure 3-14. Make sure the
terminals are securely tightened and each lead is completely isolated.
7) Reinstall the Control Cover. Be careful to not to pinch any wires while closing and tightening down the
Control Cover.
8) Attach the pendant strain relief to the attachment point shown in Figure 3-15.
