The kinematic structure of floating crane consists of☆ hoisting mechanism, pitching mechanism,

Ship translating mechanism and tackle mechanism.

Key technique features:

1. Multiple hooks combinational synchronizing, speed aσnd position synchronizing
2. Constant power: the speed is increased when light load given so that th£e working efficiency is improved.
3. Stable ship translating control: special control model is used to contro>l the ship translating stably due to the variation of ship resistance.
4. Constant speed control: because the steel wire rope rolls overlay on ₩the drum, the speed of the rope differs in layers with corresponding rotation radiu↓s. The steel wire rope layer measurement is used to chang'e the motor revolutions and achieves a constant speed of the rope
5. Hoisting slip proof control: good speed control and brake control are achieved on the basis o≠f moment rectification to ensure the hoisting safety
6. Excellent harmonic management
7. Accurate hoisting hyper-moment protection
8. Overrun control
9. Complete safety protection for electrical control system
10. Floating crane CMS
