4.1.1 Summary Observations
KFTL has fourteen (14) Quay Cranes (QC’s) all supplied by ZPMC, but in four different batches as shown in below table.
Two new Liebherr QC have been delivered and assembled on site; these are ready to be moved to the quay and placed on the gantry rails, shortly, now waiting for the heavy haulage contractor to mobilise the necessary multi axle trailers.

4.2.1 Quay Cranes Remaining Life in Cycles
The table below, together with the associated chart, shows various data, obtained from different sources in the terminal. It can be seen that most of the data is not credible, and does not reflect, a priori, the volumes handled by these cranes from the time they became operational.
As the result, some serious extrapolation of available data, had to be made to fill the large gaps of information not available on the remaining cranes.
It has been assumed, that QC #L and #M, have over their life, handled 1,920,033, and 1,890,662 moves respectively, this data obtained from the PLC of these cranes, as “twistlock count”.
As can be seen the remaining data on twistlock count is not representative and has been discarded for this assessment.
Hence, it has been assumed that each crane has handled the same number of moves, i.e. 112,000 per annum over their respective life.
