Safe system of work - Replacement of motors for conveyors systems
Preparation:
a. Gather and inspect the necessary tools and equipment, including a replacement motor, wrenches, a hoist,
a lockout/tagout kit, and safety gear (hard hat, safety glasses, gloves, steel-toed boots, etc.).
b. Obtain the relevant electrical diagrams and manuals for the conveyor system.
c. Identify the location of the motor to be replaced.
Lockout/Tagout:
a. De-energize the conveyor system by following your facility's lockout/tagout procedures.
b. Secure the main power source to prevent accidental re-energization.
1. Isolation:
a. Disconnect any ancillary equipment, such as belts or couplings, from the motor.
b. Ensure the conveyor is stable and not in motion.
c. Isolate the motor from the conveyor, ensuring it is safely supported to prevent it from falling.
2. Removing the Old Motor:
a. The third party electricians are to disconnect electrical connections to the motor as per the manufacturer's
instructions.
b. Use a hoist or lifting equipment to carefully remove the old motor from its mounting location.
c. If lifting equipment is not practical, the load must be split into smaller sections.
d. Ensure that the area is clear of personnel to avoid any accidents while lifting.
3. Inspection:
a. Inspect the new motor to ensure it's the correct model and in good condition.
b. Check alignment, wiring, and other components before installation.
4. Installation of the New Motor:
a. Position the new motor in place, aligning it with the conveyor system.
b. The third party electricians are to reconnect the electrical wiring in accordance with the manufacturer's
instructions.
c. Reinstall any ancillary equipment (belts, couplings) that were disconnected earlier.
5. Functional Testing:
a. Conduct a functional test of the conveyor system without load to ensure that the new motor operates
correctly.
b. Monitor for any unusual vibrations, sounds, or abnormalities during the test.
6. Safety Checks:
a. Ensure all guards and safety mechanisms are in place and functioning correctly.
b. Double-check all electrical connections for accuracy.
c. Verify that the lockout/tagout has not been removed until the work is complete.
7. Final Checks:
a. Conduct a final visual inspection to confirm everything is in its proper place.
b. Remove any tools and equipment from the work area.
c. Inform relevant personnel that equipment is to be reactivated.
8. Process restart:
a. Only after confirming everything is in order, remove lockout/tagout devices and reactivate the conveyor
system.
9. Documentation:
a. Document the replacement process, including any deviations, functional tests, and safety checks.
b. Inform relevant personnel about the motor replacement.
