SPECIFICATIONS
2’, 3’, or 4’ wide widths available up to 50’ long Gangways up to 20’ are available without handrail and have a 50 lb. live - load |
5-SERIES™ CAN HANDLE ALL FIVE OCEAN ENVIRONMENTS
BEAM PROFILE DESIGN ELEMENTS
#1 – Cutout for decking allows the decking to float inside the beam, on top of the fulcrum, resulting in less stress and twisting of the complete gangway structure. #2 – Fulcrum (triangle) allows the weight on the decking to disperse directly in the center of the beam reducing bending, twisting, and stress on the gangway structure. #3 – Sigma shape (half moon) design allows the weight on the gangway to disperse vertically through the side beam. This shape centers the stress through the center of the beam and also acts like a spring to absorb stress. The above three design elements, combined with engineered material thickness and flanges further contribute to the strength of the gangway. |
HANDRAIL PROFILE DESIGN ELEMENTS
The handrail uprights are a critical part of the handrail structure and have been designed to withstand a combination of loading conditions. Both the diagonal & upright extrusions were engineered to increase the live-load capability. The handrail upright & cross beam profile incorporate a square & rounded profile. The two different profiles work in conjunction for added strength in transverse and non-transverse load stresses on the gangway. Handrail uprights are welded to the gangway frame and diagonal beams are fastened with stainless steel bolts. ADA handrail options available |
