Abstract
A ship loader or unloader includes a vertically extending first region and a horizontally extending second region; a first hydraulic cylinder connected to a lower end of the first region and to the second region for translationally displacing the second region relative to the first region as a function of vertical ship motions; a bucket mechanism including a chain and buckets mounted on the chain; guides, including a guide wheel, mounted in the first and second regions for continuously guiding the chain on the first and second regions; and a chain length equalizer in the second region for varying a chain length in the second region as a function of displacements of the second region relative to the first region. The chain length equalizer includes a second hydraulic cylinder effecting a length variation of the chain. The first hydraulic cylinder is connected to and extends between a first support forming a part of the first region; and an abutment forming part of the second region. The second hydraulic cylinder is a sole hydraulic cylinder connected to and extending between the chain wheel and a second support forming a part of the second region. An actuation of the first hydraulic cylinder effects simultaneous actuation of the second cylinder.
