dirty dirty 4x4
I have a hr towbar and had to replace the hitch pin and the only one i could find at supercrap was one rated at 3.5 ton, the figures for the Haymen Reece bar is about 22,000 kgs lateral force.
whats the use of having such a high rating if the weakest link is only 3.5 ton.
My question is are there better pins out there

"Lateral force 22,000 kg." That sounds like sideways force when the hitch is inside the receiver. The direct line pulling force will spread the shearing forces on the pin to each side of the receiver which will be around a total of 7 tonnes + all the safety margins. Believe me, you will never break it .

Don't buy from supercrap it will probably be under rated.
Pay the bucks and buy a genuine Hayman Reece pin and have piece of mind.
Remember you always get what you pay for.

A genuine one wouldn't cost the earth - and they have agents all over the place - a new Treg Hitch pin for my camper was about $23 from their head office here in SA. When I think of Super Cheap, I think of safety recalls in the newspapers - not sure why...........anyway, I still
shop at SC but what I expect from them and what I'd expect from Hayman Reece is .........
well, you can guess.

This ha sbeen discussed before on here and there's stuff in Archives.
But food for thought - the shear point on a GENUINE 6 inch nail is 3 tonnes! So that gives you some indication that a towbar pin rated at 3.5 tonnes is not really all that strong. The question is - how much is there in reserve?
It's prolly better to say" The pin is rated FOR 3.5 tonnes" not "The pin is rated AT 3.5 tonnes". There's a big difference.
The problem here is when they say the pin is "rated at 3.5 tonnes" - how much more load can be applied after that before it breaks? I'd damn near guarantee that if it's made in China and sold at Supercheap, then 3.6 tonnes may
well snap it or distort it that much that you won't be able to remove it from the towbar 'cos it's bent in the middle. You get what you pay for.
Do what the offshore Oil and Gas Industry is forced to do by LAW for lifting equipment. Find a reputable seller and pay a bit more for thier product. That way, it may
well have "rated at 3.5 tonnes" stamped on it, but I'll bet my right nut that pin will do 6 tonnes before it snaps, if not more.
Other that that - you'll just have to wear it. Which may
well happen if you use Supercheap pins, shackles and jacks etc.
