Introducing new tool Key Block for side pulls from rear chain slots of a slideback

Recommended Posts

Hello: 

 

I've just developed and am promoting a new tool to perform sidepulls from the rear chain slots of a vehicle transport truck (slideback, rollback). The Key Block will replace the snatch block 90 percent of the time. You'll still want a snatch block to do true snatch work when compounding to pull really hard or from a tree or other anchor point. However, when doing any sidepull from the rear chain slots of a slideback's bed, the Key Block will become the tool of choice. Watch the video below and check out my website, KeyBlock.net. Then shoot me a message and let me know what you think. 

 

Thanks, Randy

I am a hard sell of "new" products.

The downside to this product and other already on the market like it( side puller 2000, chain lock cable pulley), is the pulley is fixed at a parallel angle to the deck.  This doesn't work for me.

A basic chain end snatch block doesn't have this limitation... and it is already on most rollbacks.

I appreciate your hard sell attitude to new products. Praise feels good, but does not improve flaws. You have a valid concern. Specifically, there can be a problem when using the Key Block to roll a car over with the bed lowered to the ground. As the car goes up on its side, the winch line can start to approach the Key Block in an alarming angle threatening to walk off of the top of the sheave. However, raising the bed back up reduces this angle. I feel the Key Block does a great job of a select number of tasks and can replace the snatch block in those cases. But a snatch block will still be a required tool and as you point out, it is already on nearly every slideback. 

 

Regarding the other tools you cite, I'm aware of the Side Puller 2000/Jr. etc. but not the "chain lock cable pulley". Can you provide a link or source for that? 

 

Thanks for your comment.

The fact that nothing is preventing the cable from slipping off under load is scary. Snatch blocks fully enclose the cable. I know NFPA and I think military require any pulling/winching anchor points to be fully enclosed, not an open hook etc. That cable could do some serious damage if it comes loose...

I appreciate your concern and agree. The winch line coming off my tool, or acting in other unexpected ways is scary. So is placing my body between freeway traffic and a tow truck / disabled vehicle. And I'm all for reducing risk where possible. But I believe my tool can be used safely and can make the rest of a difficult load out easier and quicker, which reduces risk. So I believe we are left with a dangerous job, that employs a number of tools that carry their own risk and demand appropriate respect. Snatch blocks require some sort of disassembly/reassembly to deploy. That takes time, additional time in the hot zone. J-hooks present a similar risk of not "fully enclosing" the winch line, and worse, damage it, but are sometimes used to redirect a winch line. I believe my tool presents a vastly better solution to the frequent need of redirecting the winch line at a chain slot.

As far as time in the Hot Zone, one thing ive always done and instructed my operators to do, we leave the snatch block on the cable at all times, it takes far less time to pull the snatch block to anywhere on the bed and drop the chain end in a key hole slot than it would to employ this tool.  Yes you have a good idea going on, but it needs to be refined somehow to enclose the cable to keep it from flying out under load. Will you offer it with different size pulleys?  On my rollback, I use 7/16th cable, and by the looks if it, with the 3/8 cable that was being used in the video, larger cable would come out easier.  I wish you luck with this and hope to see an update on your product.
