Security ground anchor

[thehomeengineer]

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.

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.

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.
