Operators should check decoiler motor and gearbox holding bolts, lubricate the mandrel shaft, and test the dancer arm functionality every six months.
Check the motor and gearbox bolts
Make sure the four bolts that hold the decoiler motor and gearbox to the decoiler chassis are tight. A loose bolt can lead to serious damage to the decoiler.
Note - tools required: 6mm hex key, 24mm spanner/wrench, grease
WARNING! Remove steel from roll-former and decoiler and turn the isolation switch Off before proceeding.
1. Use the 6mm hex key to loosen the six bolt caps on both the right panel and the front panel. Remove both panels.
2. Use the 24mm spanner to check the four mounting bolts.
Lubricate the mandrel shaft
Use the decoiler winder to collapse the mandrel plates completely. This will expose a large portion of the mandrel shaft. Apply grease to the shaft.
Check dancer arm functionality
Operators should make sure the dancer arm trip height is working properly.
WARNING! Remove steel from decoiler.
NOTE! Isolation switch must be On. Roll-former must be in Manual mode. Decoiler must be in Auto mode.
With dancer arm end resting on the ground:
1. Slowly raise the arm to 50mm (2”). The decoiler mandrel should start to rotate. Lower the arm below 50mm. The mandrel should stop rotating.
2.Raise the arm above 50mm (2”). The mandrel should increase speed.
3. Continue raising the arm to 1000mm – 1200mm (3’3” – 3’11). The safety control system should trigger and the decoiler should stop spinning.
