Kraiburg Bumper Question

I think this is a really dumb question but I'm going to ask it anyway :
I picked up a pair of 10 lb black , hard rubber Kraiburg bumper plates off CraigsList .I'm training in my garage with those anti-fatigue rubber mats you get at Home Depot on the floor .
My question : I was doing the Clean and Jerk WOD today and wondered , "Is it OK to drop these bumper plates from overhead ?" My left shoulder bugs me when I lower the weight from overhead so I wondered if I could just "gently" drop them as they come down from overhead . I'm not using massive weight +/- 125 lbs .
Thanks for indulging my dumb question.
Bill

Re: Kraiburg Bumper Question

What's under that mat? The reason I'm asking is that you don't want to damage anything. There's guys that drop them on concrete, but that's not recommended, because it will wear out the bumpers faster. Do you have a cheap olympic bar? If you do, avoid dropping it at all costs until you get a decent bar.

Re: Kraiburg Bumper Question

Hi Ardi;
Thanks for answering . Under the mat is concrete , the garage floor .I have another spongy type pad I could put under the drop area if that would help . Also , I'm guessing my Oly bar is kind of cheap- I got it at the local Omni Fitness about a year or so ago for ~ $ 75 I think . I'm not sure of the manufacturer . Is it possible with repeated droppings that it could shake apart ?
Is this why people use lifting platforms ? - to protect the plates and bars ?
Bill

Re: Kraiburg Bumper Question

I don't know what those 10lb bumpers look like but I have seen some that turn into floppy frisbees after being dropped frequently. Mainly because 10lb bumpers are really thin. I have a pair of Glenn Pendlays 10lb bumpers which seem very sturdy but I don't plan to drop those or let any of my buddies unless it is an accident. 25lb bumpers and up I think you can slam them all over the place with no problems.

Look at this vid from Melissa on here regarding cheap bars: http://www.xomcards.com/byersvideos.html
As far as a platform goes, if you have a Tractor Supply nearby, go and pick some stall mats this Friday. They'll have them on sale for $29.99 each.

Re: Kraiburg Bumper Question

Thanks for your answers guys.
Great video-I've met Melissa here in Nashua-great facial expression when the bar comes apart .
The bottom line : I'm going to try at all costs to avoid dropping these plates and bar- I didn't mention that I'm in my garage where the max temp is about 40 F right now , despite a small heater . So the low temp probably makes the rubber plates even more "crackable" . And who knows what my bar will do.
Thanks again for all the info . Maybe I'll contact Melissa too since she is an "expert" on Oly bar integrity.
Bill

Do you have any more info on this? Any particular mat? Do you need a coupon or anything?

Ardi;
If I put a few of those mats down in a couple of layers , do you think that would help protect the bumpers and the bar ?

I bought my 10-lb Kraiburg bumpers from this
guy: (WFS)

http://www.wwfitness.com/

coincidence?


Anyway, I don't like to drop them even when sandwiched
between two bigger wheels, they just have no strength,
but are good for light bar technique work.

You don't need a coupon and just walk in the store. http://bfads.net/Rubber-Mat-4-ft-by-...Tractor-Supply

That would be more than adequate. If you want to make it a complete platform, add a layer of plywood on the bottom of the mats and you should be set. That would be much better on your bumpers.
