WTF????
What bit don't you understand?The radiator tails should have enough play to lift it off the brackets.
If you support the radiator as it is lying flat, then no additional pressure should be placed on the tail compression joint.

As for dropping radiators... it's a crap bodge which has (as can be seen from the post above your last one) led to much water damage and work for plumber's who'd much rather do the job properly.

Locking off the valves should in theory be okay. But if you have a TRV, this'll open if the temperatures drop too low to prevent freezing. When these were installed you should have been given a cap that screws down onto the TRV instead of the actuator head.
No it won't. You take the TRV part of the valve off. The cap you screw in in it's place closes the valve like a gate valve. That said if there's a load of gunk in the system then the valves might not close fully. Besides, TRV's work the other way round, they close when it gets too hot.I'd loosen the valves a quarter turn, lay the rad down on the ground then tighten th valve back up. Miniumal water loss. When you've done reverse the procedure to re-hang the rad.
The cap will prevent them opening and flooding the room if it gets near freezing overnight.
Just thought I would update this as I did this last night with a firend and the radiator is now off and despite a little water leakage... our own fault for not properly turning off the TRV and the pressurised water coming out a little, all went well.
Some learnings for the amateurs amongst us.
- Think about the wieght of the radiator with water in (Mine was very large) as it's heavier than you think.
- Make sure your friend is at the TRV end as any pressurised water will splash him (Ha Ha)
- First time round took an hour (I know it seems like ages, but we were very cautious), next time will be about 20 mins per rad
- It was a good tip to put your finger in the holes to stop water coming out... make sure you have plenty of buckets/towel just in case
Thanks to all who contributed... just need to re-hang in a couple of days
