<p>The invention relates to a device for enabling access to a relatively moving structure such as a ship. The device has a base (1), a linkage (5, 8, 9) supported on the base and a work station (10) supported by the linkage. The linkage is adjustable controllably to vary the position of the work station (10) relative to the base (1) and means (2) are provided for attaching the work station (10) to the ship. The linkage (5, 8, 9) is automatically freed from control when the work station (1) is in position on the ship.</p> |
