CallIes"'"

TRY THE "A" FRAME Suppose a truck goes head-first inco a narrow trench ... if its engine runs, and if it has a winch, the truck can recover itself with the aid of an A-frame.

1. lash two strong poles with rope (or your tow chain) to form an A·frome, and rig a snatch blodt to the joint. You need poles at leosf 8 feet long. and 6 inches or more in diameter.

3. Run the truck's winch cable to the snatch block on the A-frame and then anchor the cable on the truck's bumper.

4. Tie a snubbing line from the frame joint to a nearby anchor. Measure the slack in the snubbing line carefully. It has to be loose enough to allow the frame to be lifted upright, and tipped over the truck's hood as the truck ts lifted out.

ANOTHER WAY A ditched truck can also winch itself forward using the A-frame. Dig the frame in so it leans over the truck's hood. Attach a (Ow chain from the frame's joint to the truck's bumper. Run the winch line through a snatch block anchored nearby, in front of the \.------==i'li-~_~\._-"-'- I load, and bring the cable back and tie it (0 the joint of the A-frame. As you pay in cable the frame will lift up taking the truck's front end with it. Un-rig the frame and pull the truck on out. 9

If the ditched truck has a dead engine and no winch it can be pulled out with another truck and the help of an A-frame. Dig in the frame, as before, but this time away out in front of the truck. Run the other truck's cable to the A-frame joint (hitch it above the joint) and then attach the cable's end to the ditched truck's front bumper.

And, here as in any recovery job, "safety comes first." Use strong poles for shear legs, dig 'em in good, anchor or block the pulling ,t ruck carefully, and prepare the areas as well as you can (dig or fill around the nosed truck, or slant or ramp trench walls if it'll help to smooth-out the pull).

WHEElS UP Recovery work always takes sweat ... but sometimes more than others. Like when one of 'em goes all the way over, or lands on its side. For safety, and to avoid further damage, this misfortune calls for two separate operations. First, it's ~t to get the vehicle right-side up again, and then you set-up to haul it out. Also, it takes twO sources of power. One to roll the vehicle over, another for holding it to check a crash landing as you pull it over. With an up-side down wheeled vehicle the recovery job usually means outriggers for the wrecker ... to keep it from toppling over . .. and plenty anchorage. 10

Also, with any over-turned vehicles, watch for spilled fuel. Mark off a "no-smoking" area before you get down to the serious wrestling. It takes a lot of force to pull one back on its feet, but with care you can roll one over with few recovery bruises. 1. The safest piau to tie on to a wheeled vehicle most always is the frome, But, pulling from one point on the frame coo bend it. So it's best to use a sling. Use fiber rope lat least l oin rope) or use your tow chain to make the sling, You tie it to the frame side that's in the air. Tie one end behind the front bumper, and the other end abowe the spring·seat bearing where the frame is stronger.

n. on a second ding at the same point. as lhe firsl, for lhe holding lin.. that'll ease lhe truck's drop os it rolls ower. (Good holding lines will help prevent damage to suspension, wheels, etc,). Power for these lines can be the front winch of another vehide, or strong ropes snubbed around trees. 3. The ground's condition, os always, has a 101 to do with your other preparations for the job. For example, you may hawe to fill-in, dig-oul, or otherwise repair the spot where it's to land up·right. 4. Soft ground, on the other hand, will help you hold the truck as you start to pull it over, If you're on hard ground, though, the truck may just slide with the pull. Holding lines from the pintle hook, frame or towing eyes, to trees, stokes, or another wehide, should do the trick for you here. 2.

s. After you've righted the truck you'll likely have to reposition the wrecker before you hook.up your tackle to pull the truck out. 11

RIGHTING A TRACKED VEHICLE

Skid Along----tf your load is lighl, and the road's fair, try this: For a 'h. or 3/4 -lon truck find a strong pole, 6 to 8 feet long, and least 4 inches in diameter. Lash the pole to the frame with a tow choin or heavy wire, Dnd remove the wheel. Then you shift into front wheel drive and you can move out s-I-o-w-I-y. h might be rough getting a start, but once you get moving it'll give you a fair ride for a good piece. On a bd Isingle or duols) truck-Raise the bum reor"wheel, and lash the axle to the frame with a tow thoin or heavy wire (take care your rigging doesn't hurt the broke lines). Remove the wheel of

and you're on your way.

QUI(K HOOK_IP

Here's one you save for desperate situations. It's set-up fast, and it's helpful in an emergency, but it's not as safe as you'd want it under normal (ondi. tions (like, with a tow bar).
