Alko Wheel lock

The point I was making is that it is a poor concept. 

I engineer vehicle parts and if I took similar concept to any vehicle manufacturer as a new improved security device they would have me escorted from site. 

I genuinely believe that ALKO do not want to improve it as they benefit from high margin on a very simple part that can not be transferred to a new vehicle thus perpetuating the sales. Fair enough if it was any good. 

This could be made into a universal part with just the same level of security very easily but then it would not generate the sales for new  vans as once you have it you would not need another one. This indeed was done see: http://caravanchannel.proboards.com/thread/3362/bulldog-max-bites-dust

A sad end to a decent bit of innovation.

Hi I had a alko wheel lock no 20 which did not fit my alloy wheel so I removed c clip .from the back .with drew the locking bolts do  fitted it to the receiver on caravan .it stuck out just enough to stop wheel turning . .and was a lot easier to fit on site  or when leaving in a car park also big red plastic marker to remind  me to remove it .or might have smashed the wheel on moving off just wish I could use it on m/home

"To the supporters of this wretched device.

Assume you have just bought your new car. On getting it home you find that it is a requirement to park it within 1mm of a wheel rotation every time you stop to meet your insurance company definition of securing it."

With cause today to move the van I thought I would check the validity of this inferred criticism.

The actual parking range precision for my Al-ko is 27 mm.

The actual lozenge clearance is  13 mm, but it is located at under half the radius of the rolling radius.

Probably, the contributors Ak-Ko is a tighter fit than mine but at just one twenty seventh it is hard to take seriously.

 There's nothing like 27mm tolerance when fitting my Alko locks ..... never measured it but nearer 1mm than 27mm

I have bought myself a second hand Bulldog Max that has a better chance of fitting the 2nd axle of my 'van ..... though the law of sod says that often, not even that will fit.

I fit the Al=ko wheel lock on the front axle and then use a Nemisis Ultra on the rear axle as fits wheel whatever position it's in.  

We are talking the "wheel rotation" tolerance for parking, not the lozenge flank tolerance, which is about half the amount the wheel moves.

As stated, I have measured mine, quite precisely, and it was 27 mm. A figure not readily misread for only a 1mm travel.

I know ..... 😙 Still, IMHO, nothing like as much as 27mm

some people have nothing better to do.

dont know what all the fuss is about. If you bought the product got it home tried it, and it wasnt fit for purpose, take the thing back and get your money back, simple. Personally i use a Milenco wheel clamp which fits every time no hassle, and an Alko hitch lock, may not be the most secure but I have read on this forum where thieves are using blow lamps to burn off wheel clamps etc so a token gesture in my book is about as good as it gets, and it keep the insurance company happy. 

I use Mailcolm's idea with the 40mm drain pipe - fits first time within minutes, although only a single axle to secure

Maybe you should patent your idea ?
