ABSTRACT:
Hoisting apparatus, comprising a side loader, passenger or freight elevator for ships, having a cage which moves along a path at least partially curved. The hoisting apparatus include an elevator shaft mounted on the ship broadside provided with one or more guide rails along which the side loader cage can be moved. The hoisting apparatus comprises at least a hoisting machine, hoisting ropes, elements moving along the guide rail or guide rails, and a lifting platform. To ensure that the lifting platform remains essentially parallel to the ship deck throughout the travel of the lifting platform, the hoisting apparatus comprises a control rail placed beside the guide rail or between the guide rails, a stabilizing element attached at one end to the lifting platform and essentially immovable relative to the lifting platform, the other end of said element running along the control rail during the motion of the cage, and a carriage placed between the stabilizing element and the lifting platform, the stabilizing element being provided with bearings allowing rotation of the carriage relative to the stabilizing element and lifting platform.
