Lifting platform for ships

This lifting platform is used to lift larger ships out of the water.
The platform is supported on 6 hoists, each with two hydraulic cylinders. The lift is controlled fully automatically by two identical control stations with an 8 inch touch display.

The maximum lifting capacity is 1000 tons. An intelligent PLC software synchronizes the 6 lifting units fully automatically when lifting and lowering the ships, so that a horizontal up / down movement is always guaranteed. To lower a vessel, it is first anchored and secured on the lifting platform, then lifted out of the water by command from the operator display. Finally, the platform is brought into a defined inclined position in order to pull the ship into the shipyard by means of a pull wire.

Since the hoist cylinders only have a stroke of 0.7 meters, the lifting and lowering of the lifting platform takes place over several steps by gripping around massive steel bars. This can be seen clearly in the time-lapse video.
