Boxing Punch Bag hung on joist (ed.)

[mrdavidj]

I am fitting a Boxing Punch Bag (60 KG) up in my garage and need some advise. I have support beams in the garage and am looking to attached the bag to one of them. The beams are 7 mm x 2 mm. I would appreciate advice: will it support this weight? how should I attatch?

Short of a structural engineer doing calculations it's not possible to be definitive, but the joists will sag less nearer the edges.

One possibility is to add a new joist spanning the width of the garage on joist hangers.

I assume by 7mm and 2mm you means 7cm and 2 cm.

On 70mm x 20mm beams I would be a little worried about the forces on that beam (its a bit thin and likley to flex).

You have a strong wall, so could use a wall mount:

Otherwise any of these hooks that are screwed into the beam, BUT these are using say 10mm screws which in 20mm thick wood might come loose quickly (do not use the rawl plugs in wood).

If it was me I would be using wall mount.

The point from which the bag is hung has to be able to resist horizontal forces as well as the vertical force from the weight of the bag.

Yes! Thank you lads. I agree the wall mounted is safes as can get heavier bag then.
