The document outlines commissioning procedures for conveyors in 3 steps: 1) Pre-start checks that ensure all components like belts, guards, idlers and safety devices are properly installed and functioning. 2) Running checks that test the empty operation of the conveyor by monitoring startup, speed, sensors and alignment. 3) Intermediate checks that load test the conveyor over extended periods to check for proper operation and identify any issues under load like misalignment or component failure. Records of the commissioning process are to be maintained.

1. Commissioning Procedures for Conveyors : (Typical )
1. Purpose & Scope
The purpose of this paper is to suggest procedures and guidelines to erectors for the commissioning of
conveyors and conveyor systems
2 Responsibilities and Authorities
It is the responsibility of the commission manager to ensure that the procedure as defined below are
implemented and adhere to.
3. Procedure
Unless otherwise specified it is a requirement that the erectors will have the conveying system prepared for
commissioning following their laid down procedures. The commissioning procedure for conveyors will then
proceed according to the following steps.
3.1 Pre-Start Checks
3.1.1 Ensure that all the belt splices are intact.
3.1.2 Ensure that all temporary construction struts, stays and steelwork are removed and that the belt
path is clear and free from obstructions
3.1.3 Check that all additional steelwork, plate work and attachments over the conveyor are secure and
that no loose members can contact the belt.
3.1.4 Check that all guarding requirements are met and that all the guards are in place and securely
fastened.
3.1.5 Check that belt travel (both carry and return side) is clear from any sharp edges on the conveyor
structure which may cause belt damage when tracking conveyor belt.
1.3.6 Ensure that all the idlers are properly aligned and securely bolted and that they can rotate freely, on
both the carrying and return strands.
3.1.7 Check that all safety devices have been installed and commissioning prior to start-up. In particular,
check that speed sensing devices are correctly installed.
3.1.8 Check that all over-travel devices are correctly located and are operational.
3.1.9 Check that all pulleys are securely fastened and aligned.
3.1.10 Check that all bearings are correctly greased.
3.1.11 Check that the motors rotate in the right direction.
3.1.12 Check that the power packs are securely fastened down and that the reducers are properly
lubricated with the correct grade filling oil.
3.1.13 Where the reducer is fitted with a holdback, check that the unit rotation is in the correct sense.
3.1.14 Check that external holdbacks are correctly fitted and that their rotation is in the correct sense.
3.1.15 Check that the holdback is correctly lubricated.
3.1.16 Check that all couplings are correctly aligned and that their transmission systems ( such as driving
pins, grids, etc ) are in place.

2. 3.1.17 Check that the coupling all lubrication requirements are met, for both high speed and low speed
locations.
3.1.18 Check that all coupling covers and guard covers are in place.
3.1.19 Check the counter-weight. In particular check that the counterweight is correctly fitted with the
design mass and that the position of the counterweight is in accordance with the design.
3.1.20 Check the condition of counterweight carriage and take-up carriage.
3.2 Running Checks
3.2.1 Place observers within the reach of the trip wire along the length of the belt.
3.2.2 Under local control start the belt empty.
3.2.3 Check the system during start-up ( acceleration ) and observe behavior of each belt.
3.2.4 Check the belt speed and the start-up time.
3.2.5 Monitor movement of the counter weight in the tower and the take-up carriage.
3.2.6 Check the location of over-travel switches and sensors.
3.2.7 Check for misalignment along the line of the belt and at the terminals, and correct as required.
3.2.8 Check controlled performance of safety devices.
3.2.9 Check reducer empty running temperature.
3.2.10 Check fluid coupling empty running temperature where fitted
3.3 Intermediate Checks
3.3.1 After running the system for a minimum of 3 hours or 10 full cycles, shut the system down and
observe the behavior.
3.3.2 Re-Check reducer oil level and top up to indicator as shown on reducer housing.
3.3.3 Run the system with material, up to the specified capacity.
3.3.4 Stop the system under load and observe any dynamic behavior which may occur.
3.3.5 Start the system under load and observe any dynamic behavior which may occur. It is necessary to
run the system for at least 10 hours to allow the belting to settle down, to identify and correct any
misalignment and identify mortality of idlers and bearings.
3.3.6 Check reducer full load running temperature.
3.3.7 Check idler seals for leaks.
4 RECORDS
The signed checklists, punch lists and commissioning certificates are classified as quality records and
should be maintained as per the requirements of the operating division.
