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 pr e-operational procedu res provided with the hoist. For Harrington ER and NER mo del hoists, follow the p re-operational procedures in the ER/NER Owner's Manual in conjuncti on with all informati on provided in thi s section for mounting and electrical connections.

3.1.2 In addition to the information and procedures provided i n this secti on for the MR trolley, there are specific details for using ER and NER h oists with MR troll eys. Special mounting a nd wiring considerations must be taken if the trolley is used with a hoist other tha n an ER or NER mo del.

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 de signed to be used with a suspender only an d do not have the vertical clearance required for a hook to fit between t he Suspension Shaft a nd trolley beam .

3.1.4 Preparing ER and NER hoists for use wit h MR trolley. 1/8 to 3 Ton ER/NER – The standard susp ension co nfiguration u ses Suspender T which orient s the

hoist perpendicular to the trolley beam. Optional two-piec e suspension method u ses a Connection Yoke and Suspender G, which orients the hoi st parallel to the troll ey beam. If the hoist is not eq uipped with Suspender T or the Connection Yoke from th e 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 so cket head bolts an d allow the co ver to swing fully open.

3) Loosen the three or four captive screws holding the electrical comp onent mounting Pla te against

the main body of the hoist and swing the plate out to access the req uired compone nts.

4) Loosen one of two Machine Screws attaching Pl ate A and remov e the second Machi ne 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 t he holes for the

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

7) Reassemble the remaining hoist component s 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).

9) There are two oil fill holes located in the top of the gear case on the ER hoist. For ER coupl ed to

MR trolley, there are some flange widths where it will be necessary to relocate the oil cap assembly to the other oil fill hole. This will prevent interference with troll ey side plate.

3 Ton (030C) and 5 Ton ER/NER – The 3 Ton (030C) and 5 Ton ER/NER hoists (double fall) alwa ys use a Connection Yoke. The standard suspension confi guration uses S uspender T which orient s the hoist perpendicular to the trolley beam. Suspen der G is availabl e as an option an d orients the h oist 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 Suspen der T or G as shown in

Figure 3-2.

8 to 20 Ton ER/NER – Since the trolley suspen sion shaft (s) passes throug h the hoist top pl ates, no additional hoist preparation is required to mount the E R hoist to the trolley. Ho ok mount ER hoist s can not be converted to lug mount without replaci ng the hoist's to p Suspension Plat es.

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 th e Suspension S haft. For beam

flanges that are wider than the standard range, diffe rent suspension shaft an d/or spacer arrangements are provided. Refer to Ta ble 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 Suspensi on 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 Space rs and Suspen der

(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 small er and ma ke 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 Suspen sion 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 t rolley switch box. Temporarily install the split pin in the Shaft Stopper Pi n and bend the split pin slightly to hold it in place. The split pin should be fully bent after checking a nd attaining the proper beam flange adjustment.

7) For ER Hoists up through 5 Ton with Su spender T - Insert the T rolley Fixing Shaft through Sid e

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 insertio n.

8) For 8 and 10 Ton ER Hoists - Insert the Tr olley Fixing Shaft through Sid e 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 Meas ure Dimension "A". Compare

dimension "A" with the following values:

 For trolleys up through 5 Ton, "A" must be 1/8 to 3/16" g reater than "B".  For trolleys 8 Ton and larger, "A" must be 7/32 to 9/32" g reater 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, irrespe ctive of the numbers in Tabl e 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 bra nches of the split pin.
