Main beam is painted with zinc rich epoxy primer. It is cut by plasma numerical control cutting machine. The butt weld of tension flange shall undergo ultrasonic or x-ray flaw detection as specified.
Outrigger consists of rigid outrigger and flexible outrigger. All connection points are connected by high-tension bolt. The ladder is used by operator to enter into cab or arriving at winch. When the span is more than 30m, it needs a flexible leg to reduce the lateral thrust of the trolley to the rail when the girder lifts materials.
