...Certain people here in the UK have it in thier heads that the Semi automatic hitches ( that have a safety pin ) are unsafe and want to ban them.
Manufacturers have already agreed to cease manufacture and supply of new semi automatics, which was a knee jerk reaction in a lot of peoples opinion, mine included.
I attended a meeting last week to try and explain to a lot of suits
( no offence intended ) that the problem isnt the hitch its the guys not using them properly.
What concerns me is that the semi autos get completely banned and then 6 months later another guy gets killed ! That will happen unless the root cause of the problem is addressed, which in my opinion is the operators/drivers not fitting the bucket correctly and checking it is secure before putting it to work.
We can argue for ever about whether that is down to lack of training, work pressure, etc etc, but it is a problem that banning semi automatic hitches in my opinion wont cure.
I'm sorry if my first posting on this forum is a bit of a rant, but I feel strongly that I ought to put the other side of the case for banning semi-automatic hitches in the UK. These circumstances may also hold true in other parts of the world.
Rob; May I start by saying that you are one of the good guys; a professional construction equipment operator who has gained the respect of everybody that you have come in contact with. However, we must all recognize that a significant proportion of operators in the UK are far less skillful than yourself, and work alongside site foreman who I wouldn't trust to run my Grandmother's candy store (I'm trying to write in American English, the Scottish expression is 'my Granny's sweetie shop').
Most of the work done in the UK construction industry utilizes rental machines in one form or another, sometimes on a short-term, self-drive basis. The point on the Health & Safety crackdown on semi-automatic hitches in the UK is that, if the construction equipment industry can not regulate itself to cater for the majority of its people, then we can expect the Government to impose such harsh regulations. As an aside, we all know that the licensing/training system for UK operators is a joke.
The deaths and serious accidents caused by the misuse of semi-automatic hitches doesn't make it worthwhile to continue down this path. The excuses of “I was just moving the bucket and didn't think it was necessary to put the pin in” or “it was raining hard and I thought the bucket was secured,” or the fact that we've all seen safety pins either missing, or made out of bits of discarded metal, doesn't hold water. But these have been the reasons given for deaths and serious accidents to our colleagues.
The whole issue of semi-automatic quick hitches is, in any case, just a temporary glitch in the continued development of construction equipment. Soon, such designs will be part of our history, not our future. For what it is worth, my opinion is as follows;
If there is no need to change the attachment on an excavator more than once or twice a week (or if the machine is only used occasionally) then the standard bucket pins will suffice. Start changing an attachment once or twice a day, then a quick-change mechanical coupler has serious advantages.
To answer the originator of this post; all the brands of mechanical quick-hitches mentioned in this thread work fine. The best way to decide which one is for you is to find a local dealer who you can trust. However, if your application is out of the ordinary – for instance using maximum breakout force – it is worth seeking-out a specialist in the field.
If the application involves frequent changes of attachment, then why not invest in a fully-automatic quick hitch system? The semi-automatic versions (requiring the operators to get out of the cab to activate a safety mechanism) are only on the market to offer a cheap alternative to modern fully-automatic designs that are the real way to maximize operator productivity and safety. Privately, the hitch manufacturers welcome this move, allowing them to focus on either simple mechanical solutions or sophisticated hydraulic automatic systems.
This is a unconventional way to say hello; I trust an alternative viewpoint (from a suit) is welcome.
