Hi Chenphop,
We have received the latest, updated copy of repair time catalogue for SPS cranes.
At the first glance, I can see that the repair time for changing slewing motor is 1 hour, not 2 hour as in the case for SPS 15800.
1. I will amend on your warranty claims for labour according to this chart and send for your review end of this month
2. In future, please use this repair time catalogue for claims on labour claims
Sorry for the delay in generating this repair time catalogue.
