Depending on what they're made of fabric straps can be exceptionally strong.
Plus I doubt that carraige is as heavy as the locos.
There are four yellow straps lifting the carriage. There's just one lifting
the power units.
I saw 4 metal chains lifting those. Rather thin looking chains IMO given
those loco sections must be at least a ton each.
Those chains look to me as if they are rated at a couple of tonnes each,
with the strap being wrapped a few times round the support and hook, for
a load rating of about 4 to 6 tonnes.
The straps used on the carriages are a size I've seen used to lift a 7
tonne narrowboat in a similar configuration.
