WARNING
The 90-ton snatch block weighs 150 lb (68 kg). Use two people when lifting or moving. Do
not lift above waist. Failure to comply may result in personnel injury.
CAUTION
Use disabled vehicle tow cables as a sling leg for recovery operation (FM 4-30.31
(WP 0131)). The use of M88A1 tow cables does not allow accurate sling leg force
calculation. Improper angle will give false-use-of-shackle estimation. Failure to comply may
result in damage to equipment.

Connect 90-ton snatch block (Figure 8, Item 1) to tow cable sling legs (Figure 8, Item 3) using two 1-1/4 inch
