So this 01 Blazer lost his A frame and the right front wheel was kinda folded under it, not quite, cuz the tire was still in the fender well which you must be careful with, cuz the wheel will move when you drag it, then the wheel will start tearing out the fender and/or fender well and you then have a damage claim.
Done right, and using tricks of the trade, you don't have to move the front wheels but maybe the last 6 inches to get it on the deck, and the folded under wheel is on a skate at that point, so that wheel does not move at all, and the skate moves about 6 inches onto the deck then chain down and snug the winch.
So how the hell do you load a car onto a roll back without dragging or rolling the wheel? This was front wheel damage, and the wheels were cut hard right cuz he was backing out of parking stall when it dropped. So imagine how much room I had on the sides to get lined up and angled to compensate for the steer wheels cut hard right. I tried to straighten out the left good steer wheel, but connected by tie rods, it would not turn due to the location of the right wheel and steer knuckle. Not much room at all for a X cab Medium duty with a 21'6" in deck. So I got the best angle I could with the room I had and backed up to the rear tires, set the deck right up to the right rear wheel, left wheel is still about 1.5 feet from touching the deck due to the angle of the Blazer. Hooked up the winch line, and snugged it up and stopped. Got in the roll back, cut the steer wheels a bit to the left, to sorta match the steer wheels of the Blazers angle. Block the left front wheel from turning, put the skate in front of the right damaged side's wheel. That must be blocked very good for this trick. You don't want the Blazer to move at all and with the right wheel dragging and the left wheel blocked, it'll hold the weight of the roll back since you're winch line is snugged up to it. Then turn off your Air Brakes, or hand brakes if Hydro, and slowly start winching the roll back under the Blazer. The roll back is moving, but the Blazer's front wheels are staying put. The Blazer trans is in N of course and the rear wheels are rolling up the deck and the roll back is turning at the same since you set the front steer wheels to match the angle. It's that simple. You winch the roll back under the Blazer, til it just about hits yours blocks/skate then go pull your air brake or set your hand brake on the roll back. Reason you do that, once the Blazer is on the deck 100% you have nothing holding your roll back from rolling away. Then you winch it just enough to get the whole wheel on the left side on the deck, and the right wheel in this case too if it's riding the skate real nice and not damaging the fender wheel. Get it on just enough and chain or strap it down. Don't bring it on the deck any further than you have to. Cuz when you go to drop it, you're going to gently slip it off the end of the deck, sometimes even a little shake, to get the front damaged wheel off, then your're going to drive out from under it, just like reversing the same procedure of sucking the roll back under the damaged vehicle.
This same procedure is used when doing FWD vechiles that are nosed in up against a wall on into a car stop like at a 7-11 when you can't get in front of it if you don't have keys or can't get it out of gear so the front wheels turn. Also used when doing repossessions so your not making noise skidding tires when you don't have the keys to get inside the vehicle or get it out of park. If their E brake is on, you Dawn and water the deck so the rear wheels will slide without making noise skidding on your deck. It's a cool trick. You oughta practice it a couple times in the yard. And when you practice it, turn the towed vehicles wheels a bit to the left or right so you can practice setting your steer wheels on your roll back to do this. Also keep in mind, you don't have to set the roll back steer wheels near as much as the towed vehicle. When you have a 19-21 foot deck, just a little turn of your steer wheels, that deck moves very fast to the left or right in comparison to the towed vechile. You don't turn the roll back steer wheels near as much as you'd think you should.
So how you like that shaking them off??? I try not to have to do that in front of the customers. I do usually keep a milk jug of water in the truck side box, and will wet the deck sometimes to shake them off. When I get back from this engine fire run I'm going on right now, I'll tell about this tow I had today. 01 Blazer lost his lower front right ball joint, and that crushed the top ball joint when it dropped. Those are fun loads on rollback.
WTH you talking about.
Pretty simple really. Just gotta be quick. I always knew well ahead of time what year make and model the car and EXACTLY where the hook points were so I could hook in the dark with the 1 AAA battery pen light FAST, help with the 2 way radios and a plain car guy. Had my bridle set, already had the winch line slacked out about 1 or 6 foot past the deck depending on where the hook points were. Also had bossman put a toggle switch on my back up beeper and shut it off for repos. Jumped out of the truck with 1 soft strap for the tail end. Get the idle up high so the bed moved fast as possible and rock and roll.
