hmmm....trolleys and forklifts then ? 
We do use hoists and other machinery if we have to. But
there are certain things that still require good ol' manual
strength.
The hospital's Occupational Health and Safety Team did mention
before that they were looking into imposing a weight limit on
patients who want to be admitted into our hospital, because the
toilet bowls, beds, chairs, etc can only safely accommodate up to a
certain weight limit, and patients who weigh upwards of 150kgs
might endanger themselves, and us, the poor nurses, if they are
allowed to be admitted here. 
Fireman used to tell me real incidents of how they had to use
cranes to lift morbidly obese people who died in their apartments /
houses out of their houses through the window! 
They were THAT huge!!
