Abstract
An arrangement for turning a turret on a ship comprises two slides that can glide along a flange arrangement being arranged on a rim of a turret. The slides are moveable by respective hydraulic cylinders and provide support for a rotatable pawl arrangement which can be rotated into and out of engagement with apertures in the rim. The two hydraulic cylinders are arranged as mirror images of each other in order for the cylinders to push the rim in opposite directions. When the turret is turned, one of the hydraulic cylinders, with the associated slide and pawl arrangement, is used to push the rim in the desired direction, while the other hydraulic cylinder with associated slide and pawl arrangement is utilized to hold the rim in a fixed position while the first slide is pulled back in order for the pawl arrangement to engage with a new aperture in the rim.
