Security ground anchor

**thehomeengineer** · Jul 29, 2023, 02:01 PM

Hi All
when my son did motocross I made a ground anchor for security to lock the bikes too. This anchor was built several years ago and have decided to reinstate it to secure other items and share the design.

The main structure is made from steel with a commercially made eyebolt modified. The locking screws are protected with a aluminium cover which is held in place with three equally distanced M6 grub-screws. A wall plate is screwed to a solid surface and accepts four M6 socket headed screws to bolt the main body too. Even if the grub screws are removed from the aluminium the chain prevents the aluminium cover from being removed and exposing the M6 socket head screws holding the anchor together to the wall plate. This is a very heavy duty ground anchor.

Photos showing installation of ground anchor:

Wall plate screwed to wall.

Main body of anchor. The bolt into the eye bolt is a shoulder bolt which allows the eyebolt to rotate.

From the front, the four M6 socket head screws hold the main body to the wall plate.

Bolted to wall plate.

Aluminium cover in place shielding all bolts.

A heavy duty chain and padlock enables items to be chained up. Perfect for securing expensive equipment in shed, garage, simply bolted to the floor or wall.

Thank you for viewing

Very good design. Given enough time, most physical security devices can be defeated. Your method is to make it so tough and frustrating that the offender realizes that it isn't worth the effort, and that works more often than not.

A floor anchor is a far more inviting target; all kinds of things might generate force to defeat it. Less so on a resilient wall, some of those methods much harder to employ.

Cordless grinders however are cheap, and effective, so as many locking points and separate chains as possible are required. My favoured ground anchor design uses thick wall box 2" section steel, cut at 45 degrees to make it safer to roll a vehicle over, long enough for 2 or 3 rawl anchors (bolt type) that are tightened through 1" holes through the top, pass the chain through and you can't undo the bolts. Cheap and reasonably effective for most things, multiplied to delay thieves so they have to cut several chains, then U locks, then difficult to access padlocks on the cast spokes of my road bikes. Such are the joys of living in an English town these days...

I think all mechanical security systems no matter how good they are or what insurance criteria they meet, they are more of a visual and nuisance deterrent than preventive. If a thief wants it bad enough they will find away. The emphasis is on the owner to make it as difficult as possible so they just move on. Unfortunately, onto their next victim. Cameras are very good as we have these at home, we will eventually install cameras at this property. But correct me if I am wrong, camera systems rely on power the internet or recording equipment to be successful. I know you can buy dummy camera's.

Camera's are no longer a deterrent, as the thieves know the Police won't even bother looking at the recording in many areas of the UK, unless your obscenely rich or well connected. In many cases it's just seen as a 'flag' you have something worth stealing, one of the advantages of the ubiquitous Ring doorbell cam's is everyone's got one in many places, so less 'flag' effect, though you have to be careful where they can see:
