Yes, there is a lot of lifting. I work peds burn unit and it usually takes two people to lift/turn a patient (even the little babies) because there are so many tubes/wires/IV's etc. A lot of our patients with new grafts (especially back or flank grafts) must be lifted straight up rather than rolled/turned to avoid damaging the graft.
A typical lift takes 2 maybe 3 people, but I've had some that take 5 or 6 depending on airway/size of patient/turning restrictions/etc.
Thankfully our management understands the need for solid staffing so we have plenty of hands on deck!
