DETAILS
The conveyor system is equipped with two shiploaders, one installed at fore and one at aft. When loading Ocean Going Vessels, the shiploaders have the chute axis distant 30 m from the centre of the foundation column and a jib inclination ranging from +12° to -10° (that can be controlled by means of hydraulic cylinders). The rotation speed at the top of the shiploader is abt. 10 m/min and the acceleration/deceleration time is 5 seconds.
The rotation is controlled by three hydraulic gearboxes fed by a hydraulic power pack. The equipment is provided with a hydraulic brake system, used while in operating conditions, and with a mechanical brake while in rest conditions (“service brake”). In operating conditions the rotation range of the shiploader is about -43° from the transversal position. The rotation of the shiploaders is limited by two magnetic limit switches (for each unit): the first generates an acoustic signal and a deceleration of the shiploader, the second stops the shiploader within the above mentioned braking time. The shiploader is installed on a high thickness steel column; the seat of the slewing bearing is placed on the top of this column.
The slewing bearing is provided with an internal teeth-range. The rotating part consists of a platform placed on top of the slewing bearing on which the support structure of the shiploader is installed. A hydraulic cylinder, manually calibrated, is provided for belt tensioning. While in rest position the shiploader is supported by two (2) rest saddles.
