I do remember the 6x4 beam across an old shed we used to put a 5 tonne

the 5 tonne pulley bent, and the beam deflected about 6 inches, did we
realise that the whole front of the car was 3 " off the deck.. 'er I
think the engine has caught on something chaps'

Weigh more than 5 tons, that Morris, did it?
