REPLACEMENT ROTARY LUG, FINAL ASSEMBLY (416000B-LTZ)

The TANDEMLOC Replacement Rotating Lift Lug is designed for Bottom Lifting — via a direct connection to the sling wire. No shackle is required as on competitor’s models, nor are they left/right handed...one size fits the right or the left!

*The Item 416000B-YPA has been replaced by either one of the two other models below, which offer enhanced corrosion resistance and can be used in low temperatures.

This lift lug fits to the side apertures of standard ISO 1161 corner fittings. It rotates to any angle of pull, however ISO 1496 does not permit 40' containers to be lifted from the bottom corners at an angle of less than 30° to the horizontal plane. The lugs fit left hand or right hand corner fittings. They do not require shackles to connect to the sling. Each is proof tested and have zinc thermal spray finish. (Zinc thermal spray is a sprayed on coating of hot zinc and is similar to hot dipped galvanizing). It is simple to use, just insert the "toe", twist 90° and lift. The roof wall of the corner fitting captures the toe and prevents fall out. The body of the assembly rotates around the toe. For added comfort for accidental disengagement, use 416000C-LSTZ.

•

NOTE: SEE BELOW FOR ISO 3874 STANDARDS FOR PROPER LIFTING FROM THE BOTTOM OF A CONTAINER.

•

USE: Use the rotary lift lug to connect lifting slings to the bottom side apertures in ISO 668 type freight container corner fittings (ISO 1161). When toe of the lug is inserted into the aperture, it is rotated manually, using the crosspin, to a lock position 90° offset from its entry position. When the sling is lifted, the flat sides of the toe head bear up onto the internal "ceiling" wall of the corner fitting and are thus held in the lock position during the lift. Because the body of the rotary lug freely rotates about the toe head, the lift sling leg can assume any angle from between 30°* to 90° from horizontal without changing the internal bearing of the toe head inside the corner.

NOTE: Once the Rotary lift lug is connected to a lift pendant, Locktite solution should be used on threads of the PC 5 Set screw to prevent unscrewing.

ISO 3874 Bottom Lift Standards

1.	The container is lifted from side apertures of four bottom corner fittings by means of slings. The bottom sling attachment shall bear on the corner fittings only and should be such to exert lifting forces not more than 38mm away from the outer face of the corner fittings. (See figure 2.)
2.	Lifting devices shall be properly engaged.
	NOTE - See footnotes to table A. Figure 1 - Lifting by means of a bottom lift sling (Dimensions in millimeters.) Figure 2 - Bottom sling attachment
3.	The applicability of bottom lift slings is given in Table A below.
4.	Folding platform-based containers (codes PL and PC; see ISO 6346), when empty and in the folded condition, may be handled in interlocked piles. The total mass of the pile shall not exceed the maximum gross mass (rating) according to ISO 668.
5.	For loaded containers, the lifting angle, a, shown in figure 1, shall not be less than the minimum values shown in Table A.
