PROOF LOADING
PROCESS OF PROOF LOADING OF HORIZONTAL AND VERTICAL LIFE LINES
The cable termination may be proof loaded upto 6KN using hydra jaws testing equipment.
The hydra jaws equipment pulls the wire out of the termination , using a hydraulic cylinder.
The pull force is increased to 6kN, & the pressure gauge ,mounted on the cylinder displays the exact
tension achieved. Once 6KN is achieved the tension is released.
Now we know that the cable termination is successful
PRE USE-CHECKS
Checks and Precautions
è
Once installed, it is important to inspect the complete line by moving the entire length of life line.
è
On site testing of the receiving structure may be provided at an extra cost.
It is mandatory for the Site Inspector/ Supervisor and the actual users of the system to perform a
thorough check of the same before carrying out work. KARAM conducts a brief training of all
concerned personnel on the subject of Pre-Use Inspection of the System as per a defined guideline
after the system has been installed by KARAM personnel.
Post Installation Inspection
Pre Use-Checks
Do not use the system receiving structure is found weak.
Checking the receiving structure
Checking the System
è
Clean the system from dust/dirt. Check for any mechanical defects.
è
Check for wear and tear in all components or unusual bending or deformation.
è
Check for any modifications done by the user.
è
Check for any missing component.
è
Check for any damages that may have been caused due to welding while maintenance of other
equipment.
è
Check the Identification Plate. The system needs to be put out of service if the label is not
legible or missing.
Checking the Cable
è
See that there is sufficient tension on the cable by checking the tension indicator in the shock
absorber.
è
Check the condition of the cable. Wear hand gloves and check the wire from all sides. Check for
broken strands or any deformity in the cable. Report if strands are found broken.
