Method of operating a shiplift

摘要

The invention relates to a method for operating a lifting mechanism having a platform, a plurality of hoists to lift the platform and a plurality of blocking mechanisms to support a load of an item to be lifted on the platform, comprising:
a. collecting position data on each of the blocking mechanisms (122);
b. reading a load on each hoist (124);
c. calculating a load on each blocking mechanism based on the position of each blocking mechanism, the loads on each hoist and a predetermined relationship between a stiffness of the platform and its load;
d. outputting the calculated load on each blocking mechanism (126).
