4.2 -- Safety Swinging Gate (Springloaded)
4.3 -- Vertical Ladder (Stainless Steel)
5. -- Lugs/Lifting Pad-eyes.
5.1 -- The manufacturer shall provide suitable lifting attachments on components or assemblies of the OILY WASTE COLLECTION TANK to provide for a four point lift directly to a crane hook using shackles and slings. The plane of each pad eye shall pass through the geometric center of the components or assemblies of the material highway to prevent side loading of shackles attached to the pad eyes.
The center of gravity shall be geometrically centered within the pad-eye locations to the maximum extent practicable to enable leveling lifting with slings of equal lengths
5.2 b Manufactured to a total thickness of .750b
5.3 -- The pad eyes shall be capable of accommodating a 2 inch shackle.
5.4 -- The lift points shall be situated such that OILY WASTE COLLECTION TANK will remain stable and level when lifted (the center of gravity must be centered, horizontally, equidistant from each pad eye) to the maximum extent practical.
5.5 -- Lifting pad-eyes shall be designed using a minimum of 5:1 factor of safety based on material ultimate strength using the minimum load capacity described below.
The padeye design for a 5 to 1 factor of safety must include a 60 degree sling angle from horizontal (30 degrees from vertical) including a 5B0 side load out of the plane of the eye with each padeye supporting half of the entire load (empty weight plus 2,000 lbs).
The lifting/handling lift points shall be sized such that two diagonally opposing pad eyes are capable of supporting the total lift capacity without the use of a spreader bar or equalizer plates.
5.6 -- The maximum gross weight includes an empty tank with residual oily waste.
5.7 -- A Professional Engineer shall provide a written statement certifying that the lifting attachments are structurally adequate for repeated lifting components or assemblies of the tank, that two pad eyes are capable of supporting the total lift capacity (empty weight plus 2,000 lbs) attributed to a 60B0 sling angle and dynamic loading, and that the lifting attachments meet all applicable American Institute of Steel Construction (AISC) and American Welding Society (AWS) design standards and requirements.
The certified statement shall be signed and dated by a Professional Engineer.
5.8 -- The pad eye's root and final weld layer shall be MT inspected. MT inspection shall be performed in accordance with ASTM E709. MT inspection acceptance criterion is no cracks are allowed. Manufacturer shall provide written certification of satisfactory MT inspection.
5.9 -- The contractor shall clearly identify the weight of the tank, the rated capacity of the pad eyes (Safe Working Load (SWL)), and rigging points on design drawings. Metal signs shall be affixed to the components as follows: Two (2) signs with 2" tall or other appropriate sized letters shall be permanently and conspicuously affixed to opposite sides of the component identifying the Oily waste tank weight with residual Oily waste weight in pounds
5.10 Load testing of pad-eyes by the contractor is not required.
Per NAVFAC P-307, testing is not required for pad-eyes that are integral attachments of components.
