Bottom beam is designed according to wind resistance, dimension of the doors and, load of the intermediate steel beams during door operations. Bottom beam also supply full closing and sealing in heavy wind conditions.
Side guides
Shipyarddoor Flexible Giant® The vertical guides shall be an integral part of the door, made of extruded aluminum with a suitable depth and width dependent on the size of the intermediate beams. The guides shall be designed to provide weather-sealing on the inside and the outside faces. The guides shall be designed to provide sufficient strength to transfer the wind load and safety arrestor forces from the door beams, at maximum wind load, to the jamb steel support system. The guides shall be easily replaceable in case of damage. The installer shall furnish jamb structural steel fasteners of size and type required for attachment of the guide rails as shown on the approved shop drawings.
Cable System
Shipyarddoors are operated with steel cable, maximum of two cable each door that running inside of the door guides. Similarly, the quantity of sheaves used to guide the belts/cables shall be minimized to reduce maintenances’ requirements and spare parts inventories. Belts/cables shall be installed free of any kinks and the system design and sheave diameter shall be such to prevent the occurrence of any kinks or abnormal stress in the operating belts/cables. Where belts/cables pass through openings in the building structure the openings shall be constructed so as to prevent abrasion, wear, or damage to the belts/cables. Sheave units shall be installed in accessible locations which allow inspection and preventive maintenance. Sheaves shall not be located in enclosed locations which are not readily accessible for visual inspection.
