3.0 Pre-operational Procedures

3.1 Assembly and Adjustment

3.1.1 When the MR trolley is combined with a hoist, follow and complete all pre-operational procedures provided with the hoist. For Harrington ER and NER model hoists, follow the pre-operational procedures in the ER/NER Owner's Manual in conjunction with all information provided in this section for mounting and electrical connections.

3.1.2 In addition to the information and procedures provided in this section for the MR trolley, there are specific details for using ER and NER hoists with MR trolleys. Special mounting and wiring considerations must be taken if the trolley is used with a hoist other than an ER or NER model.

3.1.3

WARNING

Never attempt to hook mount a hoist directly to the Suspension Shaft on trolleys up to and including 5 Ton. These trolleys are designed to be used with a suspender only and do not have the vertical clearance required for a hook to fit between the Suspension Shaft and trolley beam.

3.1.4 Preparing ER and NER hoists for use with MR trolley.

1/8 to 3 Ton ER/NER – The standard suspension configuration uses Suspender T which orients the hoist perpendicular to the trolley beam. Optional two-piece suspension method uses a Connection Yoke and Suspender G, which orients the hoist parallel to the trolley beam. If the hoist is not equipped with Suspender T or the Connection Yoke from the factory, remove the Top Hook Assembly from the hoist and install Suspender T or the Connection Yoke as follows:

1) Refer to Figure 3-1.

2) Remove the four Controller Cover socket head bolts and allow the cover to swing fully open.

3) Loosen the three or four captive screws holding the electrical component mounting Plate against

the main body of the hoist and swing the plate out to access the required components.

4) Loosen one of two Machine Screws attaching Plate A and remove the second Machine Screw.

Allow Plate A to rotate out from the retaining slot in the bottom side of the Connection Shaft. Pull out the Connection Shaft and remove the Top Hook Assembly.

5) Remove the Hoist Fixing Shaft.

6) Place Suspender T or the Connection Yoke on the top of the hoist. Line up the holes for the

Connection Shaft and the Hoist Fixing Shaft and reinsert the shafts.

7) Reassemble the remaining hoist components in reverse order of disassembly.

8) If installing the Connection Yoke, place the Connection Yoke Rubber and Suspender G in the top

of the Connection Yoke. Attach Suspender G to the Connection Yoke with the Yoke Bolt, Slotted Nut and Split Pin (cotter pin).

3 Ton (030C) and 5 Ton ER/NER – The 3 Ton (030C) and 5 Ton ER/NER hoists (double fall) always use a Connection Yoke. The standard suspension configuration uses Suspender T which orients the hoist perpendicular to the trolley beam. Suspender G is available as an option and orients the hoist parallel to the trolley beam. If the hoist is not equipped with Suspender T or G from the factory, remove the Top Hook Assembly from the Connection Yoke and install the Suspender T or G as shown in

Figure 3-2.

8 to 20 Ton ER/NER – Since the trolley suspension shaft(s) passes through the hoist top plates, no additional hoist preparation is required to mount the ER hoist to the trolley. Hook mount ER hoists can not be converted to lug mount without replacing the hoist's top Suspension Plates.

3.1.5 Trolley Assembly

1) Refer to Figure 3-3 or 3-4.

2) Remove the Shaft Stopper Pin, Side Plate S, and Spacers from the Suspension Shaft. For beam

flanges that are wider than the standard range, different suspension shaft and/or spacer arrangements are provided. Refer to Table 3-1.

3) Insert the Suspension Shaft to Side Plate G and attach it with the Suspension Shaft Bolt, Slotted

Nut and Split Pin (cotter pin). Refer to Figure 3-5 and insure that correct Suspension Shaft holes are used. Securely bend both branches of the Split Pin after insertion.

4) Referring to Figure 3-8, Table 3-1 and Table 3-2 install the inner adjusting Spacers and Suspender

(Suspension Plates for 8 to 20 Ton) on the Suspension Shaft. Use all of the Spacers provided with the trolley. If the beam width is not listed in Table 3-2, use the next size smaller and make adjustments in accordance with Section 3.1.6.

5) Place Side Plate S into the Suspension Shaft.

6) Install the outer adjusting Spacers on the Suspension Shaft outside of Side Plate S. Insert the

Shaft Stopper Pin into Hole "A" so that Split Pin is to the left when seen from the front side of trolley switch box. Temporarily install the split pin in the Shaft Stopper Pin and bend the split pin slightly to hold it in place. The split pin should be fully bent after checking and attaining the proper beam flange adjustment.

7) For ER Hoists up through 5 Ton with Suspender T - Insert the Trolley Fixing Shaft through Side

Plate G, Suspender T and Side Plate S. Secure it to Side Plate G with the two split pins. Securely bend both branches of the Split Pin after insertion.

8) For 8 and 10 Ton ER Hoists - Insert the Trolley Fixing Shaft through Side Plate G, Suspension

Plates and Side Plate S. Secure it to Side Plate G with two split pins. Securely bend both branches of the Split Pin after insertion.

3.1.6 Adjusting the trolley width - After assembling trolley per Section 3.1.5, check the adjustment as follows:

1) Refer to Figure 3-6 or 3-7.

2) Make sure both side plates are spread fully outward and Measure Dimension "A". Compare

dimension "A" with the following values:

n For trolleys up through 5 Ton, "A" must be 1/8 to 3/16" greater than "B".

n For trolleys 8 Ton and larger, "A" must be 7/32 to 9/32" greater than "B".

3) If "A" does not fall within the specified range, move spacers from inner to outer or from outer to

inner as necessary to obtain the proper "A" dimension, irrespective of the numbers in Table 3-2.

4) After obtaining the proper adjustment, install the Shaft Stopper Pin in Hole A, insert the Split Pin

into the Shaft Stopper Pin, and securely bend both branches of the split pin.

6.0 Maintenance & Handling

6.1 Lubrication

6.1.1 Lubricate the following trolley components with NLGI (National Lubricating Grease Institute) #2 or equivalent grease.

6.1.2 Track Wheel Gear – Clean and re-grease the Track Wheel gears and motor output pinion every three months (more frequently for heavier usage or severe conditions). Do not use an excessive amount of grease and avoid getting any grease on the running surfaces of the Track Wheels or the beam.

6.1.3 Gear Box – The reduction gearing in the motor should be cleaned and lubricated at least once per year for normal usage. Clean and lubricate the reduction gear assembly more frequently for heavier usage or severe conditions. Gain access to the gears by removing the four bolts that mount the motor assembly to the trolley Side Plate. Make sure to properly orient and reuse the neoprene gasket between the motor and Side Plate.

6.1.4 Suspension Pins, Bolts and Shafts – Grease at least twice per year for normal usage (more frequently for heavier usage or severe conditions).

6.2 Brake

6.2.1 The trolley motor brake is NOT adjustable.

6.2.2 Motor Brake Removal – Remove the four Bolts that attach the Motor Cover to the Motor Frame. Carefully remove the Motor Cover, brake components, and Stator.

6.2.3 Brake Lining Inspection – The brake lining is designed for a long life and should provide years of trouble-free service. If the brake lining is being inspected due to excessive trolley drift during operation (see Section 5.7), disassemble the motor brake and inspect all motor brake parts. Braking surfaces should be clean, free of grease/oil and should not be glazed. Replace the Brake Drum and/or Motor Cover if necessary. For normal inspections, the Brake Lining and Motor Cover wear should be measured as follows.

1) Refer to Table 5-6.

2) Measure the distance "A" using calipers and a straight edge. Make sure the Brake Drum is square

against the Motor Cover. Place the straight edge across the edge of the Brake Drum and measure from the straight edge to the mounting face of the Motor Cover.

3) Compare the measurement with the values listed in Table 5-6. Replace the Brake Drum and/or

Motor Cover if the "A" measurement is smaller than the discard limit.

6.2.4 Motor Brake Installation - After the brake is inspected, carefully place the Stator and brake components into the Motor Frame. Be sure to reseal the Motor Cover to Motor Frame surface using a small bead of liquid (hi-temperature) sealant. Install the Motor Cover attachment bolts.

6.3 Storage

6.3.1 The storage location should be clean and dry.

6.3.2 Care should be take to not damage any of the electrical power cords or fittings.

6.4 Outdoor Installation

6.4.1 For trolley and hoist installations that are outdoors, the trolley and hoist should be covered and protected from the weather when not in use.

6.4.2 Possibility of corrosion on components of the trolley increases for installations where salt air and high humidity are present. The trolley may require more frequent lubrication. Make frequent and regular inspections of the unit's condition and operation.
