COMMISSIONING CHECK LIST
1. I-Beam Flange width : Check actual width of beam, adjust washers to make equal running
clearance on all trolley wheels.
2. Dimensional clearance : Ensure that enough clearance is available for hoist & trolley
movement.
3. Power supply system : Ensure that ‘T’ section in case of trailing cable system or bus bar in
case of Akapp system is parallel in both axis w.r.t. Beam in straight or curved path. Trolley
pushers are designed correctly so that there is no pressure on trolley or current collector
during travel.
4. Trolley Limit Switch (Optional) : Proper actuators are provided on beam for the stopping of CT.
5. Oil level & fast ener s: Che ck levels ar e cor r ect & all f as t ene r s ar e correctly tightened.
6. Power supply Voltage : Check voltage in all 3 phases. R =Y=B= report under or over voltage.
7. Limit Switch : Check all limit switches like over hoisting, over lowering, right & left &
emergency Check the direction of motions w.r.t. Pendent buttons change phase sequence if
required. This is very important safety requirement.
8. Sufficiency of lift : Set the bottom Limit switch so that hook touches the floor & no further
Loosening of chain takes place. Set the top limit switch so that safe headroom is maintained
between hoist body and lower block.
9. Angular Loading : Check that equipment is not subjected to angular loading. Ensure that
equipment is installed at proper place proper hook approaches are used to prevent this.
10. Overloading, Extra heavy duty : Observe there is no overloading and excessive use of hoist.
11. Counter weight assembly : Ensure that counter weights are correctly assembled for balancing
of trolley bolts are properly locked & tightened.
12. Noise level : Observed that the is no abnormal noise in Hoist and travel motion.
13. Oiling : Apply oil to the chain for full length. Ensure free movement.
14. Name plate data: Note hoist, motor nos. & record them on Instruction manual for future use.
15. Instruction Manual: Read instruction manual of each product carefully & act accordingly.
16. Abnormal factors : Excessive dust, temp, humidity, chemical fumes, leakages etc. Report them.
17. Brake setting : Ensure that brake operation is not sluggish & load is not slipping. This is to
certify that equipment is commissioned on and found satisfactory for use.
