APPENDIX III, SHT # 5

NOTES RE. UNITIZING CERTIFICATE
(WIRE)

1. Name and address of unitizing plant.
   
   
2. The identifying mark is stamped on each unit produced under this standing certificate. It shall provide means of identifying the company, the mill, the machine, the wire manufacturer and the date of production.
   (e.g. bale number).
   
   
3. For the principle certificate issued for the annual production of the mill enter “all units”.
   For the particular copy given the ship the actual number of units on board should also be shown.
   
   
4. Show the maximum weight for the unit type.
   
   
5. General description e.g. eight bale, kraft pulp, unitized for bridle lift.
   
   
6. Show the number of wires which will be provided on each unit. This must give at least the safety factor strapped for.
   
   Indicate unitizing system used.
   
   
7. Show diameter and minimum breaking strength of the individual wire used. The mill test certificate for the wire is to be retained at the unitizing plant for two years.
   
   
8. The knot strength must not be less than 90% of the specified minimum breaking strength of the wire. The specified minimum breaking strength for the particular size of wire used is given by the wire supplier. So long as the knot is on the bottom of the unit, the wire strength rather than the knot strength can be used to compute the safety factor.
   
   
9. This is the minimum breaking strength required for each individual wire in the unitizing band. E.g. for a 4000 lb. unit, unitized for 40 degrees bridle lift, and banded with 6 wires for a 4:1 safety factor. 
   (Note: The bridle effect factor for 40 degrees is 1.3) 
   Min. B.S. per wire = = 1,733lbs 6
   
   
10. The minimum safety factor which must be provided is 3.5 : 1. This permits the unit to be lifted only once by its banding in Canada. Acceptance of the unit for discharge by its banding at the destination port should be confirmed by the shipper. If a 4:1 safety factor is used this is regarded as providing a safe lift condition for 4 separate lifts by its banding. E.g. the unit could be imported into Canada then trans-shipped and discharged at a subsequent port abroad.
    
    
11. This describes the lifting conditions which are to be observed. 
    e.g. Bridle lift. Two hooks. Max. bridle angle 40 degrees.
    
    
12. This records the lifting history for the particular shipment in question. The first entry would normally show the port of loading, the ship taking the cargo, and the date of loading.
