Hubbell Electric Cable Reels SHO Series User Manual

Installation and maintenance instructions, Sho series electric cable reels

background image

All units are provided with right hand rotation unless otherwise

specified. This means that cable is pulled off spool top left

or bottom right (spool rotates clockwise to wind cable)

when

viewing spring end of reel. See diagram on parts page.

Clock-type springs provide power for automatic cable take-up.

Spring must be pretensioned at time of installation to insure

that tension is applied to cable at all times. A tension adjustment

spanner wrench is provided with each reel.

INSTALLATION

1. Insure that machinery to be serviced by reel is at position

closest to reel.

2. Securely mount reel in desired position using 3/8"(M10)

bolts. Be sure spool is aligned with cable run.

3. Position optional cable guide, if reel is so equipped.

4. Connect free end of cable to junction box on machine or

adjust cable stop so that desired length of cable

extends from reel.

5. Remove cover plate on spring housing to

expose

shaft and spring hub. (See Figure 1).

6. Insert spanner wrench into holes in spring hub (Fig 2).

Rotate wrench counterclockwise (for standard rotation).

Number of 360

º turns should match last digit in model

number on serial plate. If model number includes an “R”,

reel is reverse rotation and wrench must be rotated

clockwise. (See EXPLANATION on parts list page.)

NOTE: If reel is equipped with ratcheted adjustment

wrench, follow instructions on separate sheet.

NOTE: On reels containing more than one spring, the hubs

are connected at the factory. Therefore, by tightening the

outer spring, the inside spring(s) will be tightened.

7. Remove collector cover and connect individual supply

conductors to collector terminals.

Do not attempt to relieve spring tension using spanner

wrench. Doing so may result in personal injury.

WARNING

Some reels with large or multiple springs are equipped with

a ratcheted adjustment wrench. Follow separate instruc-

tions for its use. Failure to use ratcheted wrench, on reels

so equipped, could result in serious personal injury.

INSTALLATION and MAINTENANCE INSTRUCTIONS

SHO SERIES ELECTRIC CABLE REELS

MAINTENANCE

Periodically: A. Use compressed air to clean collector assembly

and inside of collector housing. Inspect collector assembly for

brush wear and pitted slip rings.

B. Inspect cable for wear and

check mounting bolts and other

hardware for tightness.

C. Check for broken springs by

pulling about 2/3 cable off reel

and observing “Broken Spring

Indicators” on sides of spring

canisters. See Fig. 3.

NOTE: Bearings and springs

are prelubricated and require no

periodic maintenance.

SPRING REPLACEMENT

The unique SAFETYCHANGE® spring motor consists of a

spring and hub sealed within a housing. A replacement spring is

supplied sealed in its housing and the old unit should be discarded

completely.
1. Turn off all electric power.

2. Disconnect cable from machine junction box.

3. Wind all cable onto reel to relieve all spring tension.

4. Remove inspection cover from face of spring housing.

5. Rotate spool clockwise and observe inner shaft. Shaft should

rotate clockwise and hub (with spring attached) should

remain stationary.

NOTE: Do not attempt to remove spring if

resistance is met or hub tends to rotate with shaft.

Continue to rotate spool and strike end of shaft several sharp

blows with a lead hammer or rubber mallet until shaft rotates

freely and hub remains stationary.

6. Remove (4) nuts which secure spring motor(s) to frame.

7. Slide spring motor(s) off shaft and discard.

NOTE: On multi-spring reels, be sure to remove and save

dowel pins which connect one spring hub with another. Also

remove snap rings on shaft between spring housings.

8. Install replacement spring motor(s), pawls and pawl springs.

NOTE: Pawl springs must be located between the pawls

and the deepest section of the shaft grooves. Make sure that

pawls and pawl springs are inserted flush with ends of shaft and

hub or they may rub against inspection cover.

9. Tighten nuts (and extension bolts) securing spring

housing(s) to reel frame.

10. Connect free end of cable to junction box on machine or adjust

cord stop so that desired length of cord extends from reel.

11. Tension spring with spanner wrench. Refer to

INSTALLATION section.

12. Replace inspection cover.

Do not attempt to remove spring from its housing. Clock-

type springs can be dangerous to handle. Removal of

spring from housing could result in personal injury.

Do not exceed number of turns indicated on

serial plate. Over-tensioning can cause a

broken spring, sheared shaft or other damage.

CAUTION

Failure to relieve all spring tension prior to removing

cable could result in damage to equipment or

personal injury. Follow instructions carefully

CAUTION

CABLE REMOVAL

Use the following procedure to remove worn or damaged

cable from reel prior to installation of new cable.

Move machine serviced by reel to a position closest to

1.

reel. Springs will still be under pre-tension at this point.
Turn off all electric power.

2.

Lock spool to prevent turning using wither a spool lock

3.

mechanism or by tying off.
Disconnect cable from machine junction box.

4.

Grip spool by hand and

5.

carefully release spool lock or

tie. Slowly unwind remaining tension.
Again lock or tie spool to prevent rotation.

6.

Remove cable from spool. Loosen U-bolt and water-tight

7.

connector and disconnect conductors from slip ring.
Install new cable following instruction at right.

8.

CABLE INSTALLATION

Use the following procedure to replace cable or if reel was

ordered without cable. Refer to CABLE INSTALLATION

REFERENCE DRAWING, below.

Unspool new cable from shipping spool and lay out to

1.

eliminate twist.

NOTE: This step is not essential, but will aid in winding

operation of the reel and prolong cable life.

Feed one end of the cable through water-tight connector

2.

on the main shaft inside the spool and into the slip ring

side (see drawing below).

NOTE: This may require that jacket of cable be stripped to

allow conductors to pass through shaft.

Connect individual conductors to appropriate rings on

3.

collector using crimp fitting or similar connection method.
Tighten water-tight connector and U-bolt provided on

4.

drum wrapper segments.

Do not over-tighten.

Wind the cable onto the reel spool by hand rotation spool

5.

in direction it tuns free of spring tension.
Connect free end of cable to machine junction box.

6.

Pretension reel and complete installation as previously

7.

described.

COLLECTOR REPLACEMENT

Turn off all power to reel.

1.

Remove collector cover and gasket.

2.

Disconnect electric leads to and from collector.

3.

Remove drive stud bolt from bearing housing.

4.

Remove pipe plug from hole in side of housing. Insert

5.

long 1/8" Allen wrench through hold and loosen two set

screws in collector locking collar. Set screws are at 90° to

one another.

NOTE: Older reels may have lock screws which must be

removed to reach set screws holding collector to shaft.

Slide collector off shaft.

6.

Install new collector by reversing above steps.
