TM 10-5430-240-13&P 0005 00 0005 00-3 M871 and M872 M127 Anchor Assembly (M871 and M872 Trailer Bed and M127 Stake Pocket) 4. The tank is secured to the trailer with a four-belt tie-down kit. There are two anchor points per belt to provide maximum support to the tank during transport. Each anchor point consists of a 5/8” diameter eyebolt (1), two retaining plates (2), one 5/8” hex nut (3), one lock washer (4), and one flat washer (5) used on Models 91093, 91094 and PD62783-3000 only. 5. Determine the strap locations as shown and install the anchor assembly. On Models PD62783-3000 and PD62783-4750, recheck the area for sharp objects. If the surface is rough and jagged, it will be necessary to place plywood or a tarpaulin down for the tank to rest upon. 6. Attach the ratchet take-up mechanism (6) to each anchor point by using a shackle (7) between the eyebolt (1) and delta ring (8) on the ratchet take-up mechanism (6). 7. Lay the tie-down straps (9) crosswise to the length of the semi-trailer bed. Make sure straps (9) are centered accurately between the eyebolts (1). Let the remaining portion of straps (9) lay over the sides of the trailer. Straps (9) should be lying flat and not twisted. The area is now prepared for tank unfolding. Tie-Down Assembly
