then engages the snatch block 94 which is simply a pulley system which doubles the force exerted by the winch cable 44 this is accomplished by reversing the direction of the winch cable 44 on the pulley of the snatch block 94 and securing its end to the eye hook 68 thus as the winch wraps up the winch cable 44 it effectively draws the snatch block 94 towards the winch 36 the snatch block 94 in turn has a snatch block cable 96 which extends forward and which is actually the component attached to the vehicle 12 during the extraction process the use of the pulley of the snatch block 94 effectively doubles the force generated by the winch 36 and applied to the vehicle 12 which lessens the load placed on the winch thereby extending its usable life and lessening the overall cost of operations to the owner finally the manner by which the anchor pivot bar 34 is attached to the rail horizontal member 50 of the submerged vehicle extractor 10 is further detailed in fig1 and 14 the upper surface of the anchor pivot bar 34 is equipped with two pairs of vertically oriented pivot bar mounts 60 which are made up of two parallel plates configured to fit snugly on either side of the rail horizontal member 50 additionally the two plates that make up the pivot bar mounts 60 extend upwards to the point that they pass.
